Forced social isolation causes neural craving similar to hunger (scientificamerican.com)

More or less for my entire life I've had the idea that my social needs were not on par with the rest of the people, and this quarantine seems to have proven just that.

Bear in mind I do enjoy social life; when I was living in Spain in my 30s (and single) I had a very active social life, and had a moderate (~30) amount of friends split in 2 groups with which I continuously interacted.

When I left Spain for my place of origin I had only a handful of friends, and then I moved to where I live now and have only one friend, whom I see sporadically.

Nowadays I mostly interact with my partner and daughter, and the people I work with (I've been working remotely for 13 years) and to be honest, I have no cravings for social life (Except that I miss going for a stroll every once in a while at nights).


Can you really call living with your family isolation? There are people out there who live with no one, aren't near family, and can't see friends because of the lockdowns.


Yep, this me. I haven't been able to see friends or family since March 15th. So I haven't even touched another human in that long. It's been really bad for my mental health. I have a hard time empathising with people who say they've been super lonely but still live with family.


I feel you, me too. I also had a relationship fall apart late last year and did quite a lot of my own social isolating at the time combined with my natural inclination to hibernate around the winter solstice because of lack of light.

My closest friends also moved away in part motivated by the situation.

I really don't remember the last time I interacted with another human who wasn't selling me food or through a computer or phone (which helps of course but is no substitute).

There are probably a lot of us out there. If it weren't for a couple of cat monsters I probably would have lost all of my marbles by now.


>There are probably a lot of us out there. If it weren't for a couple of cat monsters I probably would have lost all of my marbles by now.

I think you might be underestimating yourself as a human being. I spend about 8 months with little human contact. I spoke twice with my parents for about 10 minutes each, once for 2 minutes to ask some questions, and maybe 10 seconds each time to the cashier when buying food (however it never deviated from this script; "Would you like bags?" "Yes." "How are you paying?" "Cash." "Have a nice day."). That was it. Nothing else.

I won't say that it was an easy or enjoyable thing to do, but I think given enough time and focus, almost anyone can probably acclimate to a complete lack of human contact without loosing all their marbles.


Long periods of isolation like this are really hard the first time you go through it. Having gone through this many times I can honestly say you learn to adjust like it were a change in seasons.

The hardest part of isolation, though, is the complete inability for somebody who has never experienced it to relate or appreciate the changes it imposes upon people.


Dude. Seems you didn't have it easy.

Also, I'm curious as to why you have been through this several times?


Military deployments and military schools. My first one of these that I count was my first deployment in 2004 because my first kiddo was 4 months old.


Feeling it too. Last few weeks I decided that I was going to negotiate some limited contact (occasional masked walks and hugs) with a few select people.

This is arguably a little irresponsible of me; I have a housemate who is a social worker and not isolating, which makes me a potential link in a transmission chain. But on the other hand, we're spending nearly zero time together in shared spaces (we literally go weeks w/o seeing each other) and I'm very conscientious about what I touch and when in shared spaces. And delivery or random passers-by on walks are my only other form of exposure, so it seems like a managed risk if not absolutely minimized.

I think some who live alone are going to find this kind of quaran-team approach important as we break past the first few miles of the marathon. The trick may be in really doing it thoughtfully in a planned-out conscientious manner rather than waiting until arriving at some breaking point and throwing caution to the wind.


> This is arguably a little irresponsible of me

I'd say it isn't irresponsible at all. You've got to do what you need to do to look after your own mental health. One thing I am utterly sick of is the shaming of anyone that breaks "the rules" that seems to have become normalised. Especially when it comes from people who have families and partners at home.

We seem to be obsessed with the idea that you could be somehow responsible for someone's death if they get infected via you, even after several degrees of separation. I guess this idea has some logic to it, but it's such a departure from how we think about things normally.

By the same logic, many of us have probably helped to "kill" a few elderly/vulnerable people in the past by passing on the influenza virus.

I'm not saying we shouldn't all take sensible precautions, like isolating when you have symptoms and hand washing etc. But this shaming needs to stop.


I think it should be fine if you form a very small group and only ever meet these same people (optimally outside with a bit of distance of course). It shouldn't be that much different from people living in a medium-size household and much better for mental health.


Yeah, similar boat. I was content with the arrangement for about two months. I finally relaxed my shelter in place a little before memorial day. The point of living in a desirable area and within a city was to randomly meet people that also had their life together, while working on the career and financial circumstances that allow you to do this.

With SIP, everything closed, and ongoing social distancing none of that is possible and you're also cut off from other social circles if you hadn't locked in a core friend group or significant other.

I could really the see value of these areas plummeting much harder than before. Even when thinking of the protests as having some allure for being social, many of the people are from surrounding suburbs coming in for the action, whereas the wealthy transplants have already left indefinitely.

I don't get the impression that those with family are overwhelmingly content. But some have routine at this point and aren't considering the social starving that people in different arrangements may be going through.


> Even when thinking of the protests as having some allure for being social

I have wondered if there’s an aspect of that in the huge turnouts. People are unemployed and isolated, and joining the protests gives them a chance to feel like part of something.


All my friends are doing this to get out and protest. I've also started doing it from the weekend.


I'm sorry to hear that. The reality is that there's no substitute for human touch.

Obviously it's an incredible complex decision, but have you thought about getting a pet? (If that's within your possibilities)


I've been going to protests. Can you try that maybe? I felt lots of camaraderie. I've been wearing facemasks and a face shield which makes it a little hard to interact with people in crowd though.


> I have a hard time empathising with people who say they've been super lonely but still live with family.

This. They have no idea.

Point in case, my friends group starting organising weekly group video calls, to see each other and play scribl.io. After a few weeks it quickly became apparent who was really isolated and who had a partner or even just flat mates. The isolated people were really looking forward to the video chat (also you could tell they were more grumpy / on edge than usual). People who don't live alone, started missing the video chat evenings because video chat is such a poor substitute for actual social contact, it really wasn't bringing them anything.

I'm glad to hear (elsewhere ITT) that isolation is worst the first time you go through it. Because I'm fully expecting a second wave when autumn hits or something. And I fully expect people who do not live alone to continue being oblivious to the mental state of the isolated ones.


Do most people consider going 2.5 months without touch a long time??????


No reason to stay so isolated now that covid testing is widely available. Get tested, have your friends get tested, hang out, be human.


This fits me, and I have 0 problems with it. Do I want to see my friends again? Yes. But as I don´t live in my home country anymore, I´m accustomed to only seeing friends and families a couple of times a year.

Takes a bit of effort and empathy to remember that I'm an outlier and people truly did suffer during lockdown.

I really wonder, how many people are there like me? What's the distribution? You naturally hear mostly from social people and extroverts. Hope there are some studies going on right now.


Well, guess you are correct here, I can't call my current situation isolation.

But there have been times where I've been there (My partner tends to go on extended vacations with her mother) and, even without quarantine, I've been locked up all by myself only going out a couple of times a week only for grocery shopping.

I enjoy reading an investigating things (And for programming related discoveries, time gets consumed too fast) probably a bit too much, and there are times when even family comes in the way.


there are even more severe forms of isolation, but yes only spending time around the nuclear family is a form of isolation. Friends, peers, church (or secular equivalents), the wider community and so on all provide forms of social interaction that don't exist within the immediate family and that humans generally are accustomed too and need.

In fact, the detrimental effects of long term isolation only surrounded by the nuclear family is a common theme in American fiction in particular (American Beauty), or even in horror as in The Shining.


Okay sure, but try not seeing any friends AND having no partner/children.

There are literally consecutive days in a row where I spend 0 minutes in a day talking aloud to a living person. Less so now that the restrictions have been lifted, but the last few months were significantly harder for me as a person living on their own who wasn't able to see friends than for my friends who at least could share their experience with someone else.

Not saying people who had families shouldn't feel like they are isolated, but I'd easily take the isolation with the partner experience over isolation with literally zero people experience.


Exactly, family is its own community.


Yes, this has certainly solidified my understanding of myself as an introvert... I am stuck home with my wife and two young kids, and I mostly want more alone time... I don't miss seeing other people.


Same here. Though, I do wonder if it'd be a case of _be careful what you wish for_ if, for some reason, all of the sudden I was completely isolated.


Same here, including your worry.


Being around your partner and daughter is social.


Well, yes. But it's not the same, and I'm in this boat as well:

https://news.ycombinator.com/item?id=23460927


The article is about severe social isolation, meaning you don't interact with another person in any way.

> the researchers had 40 socially-connected healthy human adults spend 10 hours (9am to 7pm) alone, with no social interaction and no other social stimulation (e.g., twitter, email, reading fiction).

I'm not even sure what I could do during the day to avoid social interactions to this extent.


I do wonder what the participants were allowed to do. It’s possible they just measured the effects of terminal boredom.


Yes, I understand that. But also from the article:

> Participants with higher levels of chronic loneliness at baseline reported less craving for social contact after 10 hours of isolation

Based on what the article states I guess this is similar to people that react differently to fasting; those that are used to loneliness for whatever reason (In my particular case I understand it to be my "natural" state) are better prepared to go through this.

I guess the idea was to be able to _really_ measure the effect of being alone in the least harmful way so they went all in (Not even allowing the participants to read) trying to make the time of the experiment as short as possible.


I've been almost completely alone for about 3 months now, at least physically. And honestly... I couldn't feel much happier in that regard. It's been great. Maybe I'm broken or something.


Not broken just a different type of person. See this episode from Mythbusters about Cabin Fever: https://www.dailymotion.com/video/x2m7k1y

You're more like Jamie.


That explains fair amount of us, I think. I'm on the same camp. It makes it a bit challenging as my wife is extremely social, so finding balance is a bit tough for both of us :)


I have the same issue. My wife is going absolutely stir-crazy and dreaming of all the adventures, while I'm absolutely happy to be productive at home with relatively few distractions.


Well, my partner has the same issue.

Even thought we are living in this city because it was the best for her career (She's a professional flamenco "bailaora" and where we lived before her career was dead in the water) she doesn't have a large amount of friends, but boy does she crave for going out.

She is really having a bad time going through this, while I'm surfing the wave without issues.


Same here. The missus is almost crawling on the walls due to the lack of social contact, while I'm having the time of my life; the lack of social interactions gives me so much extra spare time.


If you live with a partner and a daughter, you're not socially isolated.

I really get a strong feeling that a lot of people who do not live alone, have no idea what others who live alone actually went through (during lockdown / quarantine). It's hard to explain, it's like being lost at sea, maybe. My mind just started blanking all the time


Sounds like a normal introvert.

extroverts get recharged by being with more people.

introverts get recharged by being with fewer people.


Regarding that matter, I found this comment also in this thread interesting:

https://news.ycombinator.com/item?id=23462232


I think social needs are not static, it depends on what you are become used to.


I am an introvert. Many people (including many introverts) thinks this means you don't like people or social gatherings. That's not the case. Or at least it's not necessarily true.

Here's the best way I can describe it: being an introvert means that social interactions cost you energy. Being an extrovert (since I'm not one) seems to mean that social interactions gain you energy.

I see this in a relative of mine who is clearly an extrovert. Social interactions are her drug. She craves them and gets almost like a high from them and honestly gets really hyper as a result.

Compare this to me. At work I've had these extended work gatherings for several days where it's a lot of team-building, brainstorming and so on. By the end of the day I'm physically exhausted from all these interactions. Some people are not. Some will go to dinner in the evenings then out to a bar to drink and then back to someone's Airbnb for another gathering after that. That's all fine for them but it's just way too much for me.

So it's not like I don't like interacting with these people. It's merely a question of how much mental energy I'm capable of expending before I need to recharge.

So you see these differences really exposed by the forced isolation. I miss some of the interaction (and, to be fair, the food) of being in the office but otherwise I'm fine. You can clearly see that other people are not. While I have a natural excuse to avoid many draining activities, others are clearly being denied their recharging activities.

So yeah, I can totally buy neural cravings here. For some.


For me, part of the draining effect isn't just due to being an introvert... it's because I tend to engage far too willingly in what most would treat as shallow casual interactions.

I tend to treat even strangers with too much respect to give them less than my full attention and thoughtful responses. That makes it a draining chore.


Er, yeah, I've been saying this for months.

We are social animals. Literally just existing is stressful at the moment for most of us, because there's a constant urge that is not being satisfied.

Not only for socialisation but simply the low-level stress of constantly having to 'check yourself' when you realise literally everything you'd normally be doing is either disabled or handicapped in some way.

To me, lockdowns feel like some sort of irrational loss aversion strategy. If you gave me the option in, say, 2017, of halving my mortality rate for a year, but the cost was that I had to endure relatively strong anxiety for that year, there's no way I'd take that bet regardless of my age.

Mucking around with your mental health is not wise. Add on top of that all of the economic effects, the political effects of dividing populations, domestic abuse, "non-essential" healthcare like dentistry, and so on and so forth, and honestly I reckon it's been a net negative.


I've found this period has had an overall positive effect on my mental health. At first I was rather depressed, religiously following the news and subreddits about what was happening, but after a couple of weeks of that I realised I couldn't continue living like that forever. I started introspecting and tried to figure out what was causing the stress and low level anxiety I've been experiencing for a few years.

During this period I feel like I have figured a lot of things out, and overall feel more relaxed now than I did before quarantine. I realised that I was putting a lot of pressure on myself to achieve things, and I don't need to - at first I used the pandemic situation as an excuse to myself to not have to do these things, but now I just feel naturally relaxed.

Also as a newish (1 year old) father I found talks by Gabor Maté resonated a lot with me.

(And I've somehow lost 6kg - even though I've been cooking whatever tasty deserts I've found on YouTube - probably from not eating out)


This is totally ad hominem but I'm just going to go for it, because I think you've missed the point of what 'social isolation' is -

"Also as a newish (1 year old) father I found talks by Gabor Maté resonated a lot with me."

I assume your child (and partner) haven't been 200 miles away for 3 months, inaccessible because taking a train is pseudo-illegal or frowned upon by society at the moment.

I assume you've been cuddling them without thinking that every journey, every interaction point, is some 'vector' bullshit.

If I'm making the wrong assumptions here, and you're actually watching your child's formative years through a video link, I feel for you, but I can't believe that's the case because there's no way that a normal human would claim that were a superior state of affairs.

Come on, man. Please think before posting.


Mortality isn't everything. You don't seem to be taking into account the suffering of people who survive -- but are often very sick for quite a long time, and may never fully recover -- and the extra anxiety caused by an unchecked deadly pandemic. (Or if you are, you don't seem to think it is very significant?) In this comment you also seem to ignore that the trade-off isn't just about increasing your risk, but everyone's, including the people you care about -- though I think you acknowledge it in another reply.

Even if I got lucky enough that nobody close to me died and I suffered no permanent damage myself, personally I would feel immense anxiety knowing that the virus was likely to affect many of the people I care about (and also that I had limited but non-zero control over this, so I could neither try to ignore it nor bring the odds down far enough to feel optimistic), watching some of them suffer and wondering whether they would make it, possibly suffering myself and wondering how bad it would get and how fully I would recover, and so on. That's aside from the effect of empathising with strangers suffering and dying at a much higher rate than usual, too.

(I'm in Australia, where so far our measures have kept the infection rate very low. Maybe you feel like you've experienced something closer to the worst of both worlds?)


I'm in Tasmania, the State and the people here have done a very reasonable job.

Tasmania: 13 deaths, 228 confirmed cases, zero new cases in the past 24hrs, 33,000 test conducted.

Active cases in Tasmania: 2

The restrictions here have certainly had an impact on our lives, and I can hardly imagine how it would feel to be in an area with many more cases and more strict restrictions.


The problem with your analysis is that you're not considering just how much "loss" we were averting via lockdowns. Do you think those negative effects of our partial lockdowns outweigh 5X more COVID casualties, including many from preventable deaths that have nothing to do with COVID? We need a functional healthcare system, we could not allow it to become overwhelmed and collapse. There's also the ethical issue of allowing a disease to run rampant and ravage our elderly population - could we recover morally and ethically if we allowed 100's of thousands of older folks to die long, painful deaths so our economy was a tad stronger?


On that last part, I will confess it's unclear to me what the greater moral failing is between the 100s of thousands of elderly deaths, and lost economic growth. It comes down to how much is actually lost of course, and while I do believe what we're collectively going for is a good middle ground, I think also a lot of people don't really understand the magnitude of effects of economic growth over long periods of time.

The difference between growth of 2% and 3% are enormous 50 years down the line, and may very well translate in many more deaths due to poverty and disease, as well as a great quality of life difference for billions of people (among many other effects).


There are also mental health consequences to large-scale death and hospitals being over capacity. Would you choose a year of watching your friends and family randomly die over a year of staying home most of the time?


I believe my comment about halving mortality addresses this.

They're already likely to arbitrarily die - if in 2017 I could reduce that probability by half (coronavirus roughly doubles mortality across all age groups) by having everyone stay inside or perform the various rituals like standing far apart, wearing masks etc I wouldn't do it.

If instead of decreasing life expectancy by less than a year it were something like 10 (and so we went full hazmat, disallowing things like even entering a supermarket in favour of MRE deliveries) then the calculus would be different.

The main inescapable issue, which exists lockdown or not, is visiting elderly or immunocompromised relatives, not because of the absolute risk, but because of the impact that being able to say "my visit probably killed Grandma" would have.


Coronavirus may only double overall mortality, but having no hospital capacity would cause a further increase in deaths. We'd probably just end up in a real lockdown (shelter in place orders are not a lockdown) and have a bunch of extra dead people.


You could always get both.

I haven't seen another human other than through zoom since march 15th.

Meanwhile, my extended family, people I love, are ignoring isolation mandates and out and about, hosting gatherings, like normal. Many of them are seniors with chronic conditions that put them at high risk for covid complications / mortality.

I'm depressed as fuck staying home all the time and waiting for the inevitable as covid reaps my loved ones.


yeah I did maybe a little after march 15th till late may. around early may I found myself pacing around my apartment saying "this is bullshit" more than once per day. referring to the scenario itself, not the utility of the lockdown mandates - yet.

but I can definitely go two months without physical human interaction! video conferences, video dates, video for sake of video? CALL OF DUTY: WARZONE? all of those are chores to me.


We should definitely be beginning to examine the mental health toll the lockdowns are having on people. Changing our behaviour for the sole purpose of extending our life expectancies as long as possible is not living at all.


"We are social animals." Are we though? We're not like a flock of fish, herd of sheep, pack of wolves not even like apes. Or when was the last time you met a silverback human?

If we keep indoctrinate that, we may miss the real solutions.


This was Maslow's point from back in the 40s, that there's no real distinction between physiological and social hunger, besides the fact of an importance hierarchy (one needs to be decently fed in order to start caring a lot about sociality, although even a person in starvation may care somewhat).

Glad to see it's being neurologically researched as well.


Yes, all needs in the hierarchy are basic and necessary!


I wouldn't classify social interaction as a need. There's plenty of examples of people without any human contact surviving, to the point that we have a well established word for these people; hermit.

Imperial Japanese holdouts after the end of WW2 are the classical example, and to a lesser degree you have hikikomori in modern day. The most extreme example is Christopher Thomas Knight (the North Pond Hermit) with only one claim instance of human interaction in that period; he said, "Hi" to a hiker.

A need has a specific meaning; more or less, you will die if you don't have water for more then a week. It doesn't matter how strong willed you are, lack of water will kill you. Lack of social interaction will not universally kill everyone.


Maslow was working with a theory of human motivation, not just survival. I quote the following from his original text https://psychclassics.yorku.ca/Maslow/motivation.htm:

> what happens to man's desires when there is plenty of bread and when his belly is chronically filled?

> At once other (and 'higher') needs emerge and these, rather than physiological hungers, dominate the organism. And when these in turn are satisfied, again new (and still 'higher') needs emerge and so on. This is what we mean by saying that the basic human needs are organized into a hierarchy of relative prepotency.

> One main implication of this phrasing is that gratification becomes as important a concept as deprivation in motivation theory, for it releases the organism from the domination of a relatively more physiological need, permitting thereby the emergence of other more social goals. The physiological needs, along with their partial goals, when chronically gratified cease to exist as active determinants or organizers of behavior. They now exist only in a potential fashion in the sense that they may emerge again to dominate the organism if they are thwarted. But a want that is satisfied is no longer a want. The organism is dominated and its behavior organized only by unsatisfied needs. If hunger is satisfied, it becomes unimportant in the current dynamics of the individual.

Basically, Maslow's definition of a "need" is "a human drive that acts as a determinant of behavior" and not purely in the sense of "a physiological requirement for survival".

You may disagree with his framework as presented (I do, but on psychoanalytic grounds, that it's overgeneralized, lacking a few steps in terms of how individuals interact with desire, and therefore only sociologically and not individually useful), but it seems difficult to argue humans lack "psychical needs" of some form beyond pure physiology.

In the case of hikikomori, recall that they spend a lot of time with media, creating "parasocial" relationships, or even on (usually anonymous) social media websites, which do offer a form of social interaction and connectedness. But there is a reason why very few individuals end up as genuine hermits, without any social interaction whatsoever.


Please review Maslow's Hierarchy of Needs [1]. I'm just communicating what he said in his book Motivation and Personality. His theory is taught in every introduction to psychology textbook.

I enjoyed a non personal specific event. Thank you.


Honestly its scary the talk of another year like this. I have a family and even with them around living all day in my apt is starting to drive me crazy. I'd hate to be living by myself. Its a lot like solitary confinement.

My Brother had the bug, had a mild cough for a few days and lost his taste. I'm very jealous.


It's funny because I am having the opposite issue... stuck at home with my wife and two young kids, and what I want is MORE alone time. I need daycare!


Try spending 2+ months in an 18m² apartment alone AND under the obligation of following courses and studying for exams. Being a college student in a French elite school sucks.


Is that a CitéU? Or just your avg. attic conversion?

(But yes it sucks)


À la CitéU but down in Saclay.


> Honestly its scary the talk of another year like this.

I don't think anyone is seriously suggesting you will not be able to leave your house for another year. I think everywhere has concrete plans to re-open everything short of mass gatherings pretty soon. That's the cautious countries and the less cautious countries alike.


The open or closed status of everything has little to do with whether or not you should engage in non-essential visits. Policymakers do not schedule the virus.


The 'non-essential' guidance is also being relaxed in all locations I've seen reporting on. Most are encouraging distanced socialising and return to work.


The non-essential guidance has little bearing on whether or not someone should engage in non-essential visits, as policymakers do not schedule the virus.


It also seems to have little bearing on how essential an activity is, and it hastens the ongoing consolidation of our economy into a small number of enormous companies.

Personal anecdote: I need a biopsy from a specialist surgeon who does not treat respiratory diseases and does not reside in a hospital.

Sorry. That's non-essential. I haven't been able to get it done, and it's been months. I'm also on COBRA, so...clock's ticking.

But if I want to buy a paperback? Well I can't visit my favorite local bookstore which is usually quite empty (non-essential), but I can go to a packed Walmart or order it off Amazon.


The virus alone also doesn’t schedule human behavior. I’m not sure exactly what you are implying.


If that is the case, why were non-essential businesses shut down and shelter in place orders enacted all over the world?


I was simply trying to point out the other side of what I felt was an overly rigid line of thinking from the GP.

The shutdowns were a tactic taken with limited information and imperfect effectiveness. I don’t think it was the wrong thing to do. However, we could have and should have had a more effective, sophisticated, and timely response across the board.


I don't know what you mean about 'scheduling the virus', sorry. Generally people are probably best off listening to official advice, not making their own assumptions.


> I don’t know what you mean about ‘scheduling the virus’

They’re saying just because non-essential restrictions have been relaxed doesn’t mean you should partake in non-essential activities.

I agree with them, but not everyone will.


Yeah I go outside 2-3 times a week already. I just want to visit my parents, sit at a proper desk, and have my children play with some friends.


Currently around ~5% of the US has contracted COVID. 60-70% of the population needs to become infected in order to gain herd immunity. Meaning we're about 7% of the way to herd immunity. We still have a long way to go.


We have no idea what the required percentage of infection is for herd immunity, given that we don't know what percentage of people are naturally immune or resistant, what percentage of people clear the virus without any antibody response, etc.

There is a decent amount of research beginning to indicate we won't need nearly that level of infection to reach herd immunity. It's not guaranteed but I'd keep an open mind.

https://arxiv.org/abs/2005.03085 https://www.ncbi.nlm.nih.gov/pubmed/32209383 https://www.medrxiv.org/content/10.1101/2020.04.27.20081893v...


I don't think anyone's saying they're aiming at herd immunity any more, are they? The European and North American countries opening up, which is all of them, are just saying they have the situation generally under control enough to relax restrictions.


I mean it will continue to spread until that percent of the of the population is infected. Containment is not possible. So right now it's a balancing act of opening up the economy and preventing an explosive outbreak. The hope is a vaccine will be created soon and a large proportion of the population will gain immunity through a vaccine rather than just naturally contracting the virus.


Yes. Those restrictions were from the time we were thinking the virus is more deadly than this (1-2% IFR).

Now with more publications, data suggests an IFR of 0.1-0.6%. Which is pretty low and does not worth crashing the economy.

This does not mean vulnerable people has to pay the price no. It is trade off. We have to reopen and go back to normal, while helping vulnerable people.

Even some paper suggest far more infections than we thought.


I don't know where you're getting that IFR figure from. Let's take the UK: 7% of the population have had it[1], and about 60,000 people[2] have died (!). That's 1.3%.

[1]https://www.bbc.co.uk/news/health-52837593 [2]https://www.bbc.co.uk/news/health-52976580q


The IFR is proving to be ~1%.

For 0.1-0.6% to be true, 50-100% of NYC would have to have gotten infected with COVID-19...


IFR is not a fixed value and is affected by many things. For example, intial viral load may be higher in NYC than many other places, vitamin D levels, air pollution, etc. There is no single IFR for any disease.


Yes, IFR is not a fixed value. But a range (0.1-0.6%) was provided by the person I was responding to. Even assuming NYC hit the top of the range of IFRs (which seems questionable given that NYC isn't a particularly old city), one would need an infection rate of 50%, which contradicts serology studies that turned out to be half that.

IFR in other locations (e.g. small towns in Europe where blood tests show widespread exposure) has also consistently come in at roughly 1%.


The data you are putting out there is completely wrong.

You can check this subreddit for publications: https://www.reddit.com/r/COVID19/

All most all the publications from the past 2 months show an IFR if 0.1-0.6 or at most 0.8%.



Funny how you cherry picking those.

confirmation bias. Look at the other publications.


To prove that 0.1-0.6% is wrong, one only needs to show a single example that had an IFR > 0.6%. I provided several. You meanwhile have provided none.

And this range of IFR estimates (~0.7-1.1%) is what you tend to see across localities where serological tests result in substantial positive antibody rates. Studies based on low (e.g. <5%) exposure rates aren't that meaningful because false positives can dwarf the true-positives, skewing the results.


> You meanwhile have provided none.

When I say you cherrypick, I am talking about this:

https://www.reddit.com/r/COVID19/comments/g4tqvk/dutch_antib...

And so, so mare which I don’t have time to find one by one right now. Like the study from Finland, or other places.

I don’t have anything to add to this discussion, since this clearly shows you are incapable of research. One other point is there is non negligible amount of people who does not develop antibodies therefore they are not detected in serological tests. I would expect IFR go down.

(You could have find in other publications too:

The only required skill required is googling and having open mind.)

“ Iceland, (1st May) reports ten deaths in 1798 patients, CFR. 0.56%. If we assumed 1% of the population (364,000) is infected, then the corresponding IFR would be 10/3640 = 0.3%. Iceland’s test and quarantine measures may have shielded the elderly group, and deaths may still go up as they lag infection by about two weeks.

Iceland’s higher rates of testing, the smaller population, and their ability to ascertain all those with Sars-CoV-2 means they can obtain. an accurate estimate of the CFR and the IFR during the pandemic (most countries will only be able to do this after the pandemic).

Current data from Iceland suggests their IFR is somewhere between 0.3% and 0.56%.” -CEBM

P.S. FYI Iceland has done more test than anybody I think (ratiowise).

I have a suggestion for you: READ MORE!


That's only if infection grants lifetime immunity. Other coronaviruses (like those that cause colds) only grant immunity for 4-12 months. We don't know if this coronavirus is the same, but if it is, we may not be able to achieve that herd immunity without biannual vaccinations.


One of the things that scares me a lot about covid is the risk of losing my sense of smell and/or taste.

So I'm not sure if I would be jealous of your brother.

I mean, sure, I'm also tired of this, but just thinking that I could potentially never smell coffee again, or taste avocado or not being able to notice the scent of my partner, or lot of other things... it's terryfing.


I guess he can eat the same food all the time now then


The one person I know who had covid said they didn't want to eat anything. It wasn't just that you lose taste/smell, it's that everything tasted/smelled funny.


Is it a permanent loss of taste or do your senses come back after?


For some it's come back. More rarely it stays gone for months. Hard to know about 'permanent' since it's only been 6 months this thing has been around.


Texture is (just/almost) as important as taste!


Once you get used to protein shakes, you can stomach almost any texture.


I blend frozen banana, peanut butter, milk, Greek yogurt, and protein powder together and it’s as good as any milkshake (once you get the proportions right). The frozen banana seems to be the key for giving smoothies a creamy texture.

Everyone: if you drink protein powder mixed with water, you are committing a food crime.


Not even close.


I have been having backyard beers with a friend at a time, at a distance, on nice days. Feels safe enough and it is nice to see friends!


I've spent the majority of my life in social isolation, mainly because I keep forgetting to maintain relationships. I'd drop off the radar for months on end, until a concerned friend or family member would manage to get in contact with me (I don't use social media because it's too much bother to maintain). In 2001, after the dotcom crash, I took a yearlong sabbatical where I saw no one, spoke to no one, and by the time I was pulled into the open again it hurt to speak.

TBH until I met my wife, I never thought it possible to be comfortable living with someone.

I know I'm an extreme exception, but I'm one of those people who don't feel a craving for human contact.


That's not forced; that's your choice. I'm someone who also naturally ends up being alone, however, being forced to be alone is a completely different situation. The power of choice is everything and it seems essential to this study.


That conclusion of the study is highly suspect. "To address this challenge, the researchers had 40 socially-connected healthy human adults spend 10 hours (9am to 7pm) alone, with no social interaction and no other social stimulation (e.g., twitter, email, reading fiction)."

The subjects chose to spend 10 hours away from all social interaction in order to participate in the study. That's not the same as being forced.

However, the results were striking. Just like choosing to fast from food, choosing to fast from social interaction caused similar cravings in the subjects.


We need to ban solitary confinement in prisons.


I have a lot more sympathy for animals in the zoo as well.


I have never liked zoos! The animals look so sad. The San Diego and Cincinnati zoos are very large and that helps, but I still don't enjoy going to them. The reptiles are usually fine, but many of the mammals really shouldn't be locked up like that. A polar bear swims up to 600km a day in the wild.

I like aquariums. Most fish are fine in a big enough tank; turtles too. I avoid aquariums with Dolphins or Whales. Considering how much they swim in the while, that seems cruel too.


> A polar bear swims up to 600km a day in the wild.

Off topic, but there's no way that can be true. 600km in a day is 25 km / hour for 24 hours straight. Looking online, it looks like the top swimming speed of a polar bear is closer to 10 km / hour.

That said, I agree about the sadness of zoos.


In some countries it's illegal to have just one of a kind of some animals as a pet.


Would explain why I'm eating a bowl of cereal at 9PM nowadays...

I would encourage people to see friends at a distance whenever possible. We must remember to balance our mental health (greatly affected by seeing others) with our physical health.


I just haven't been able to read books when I've been isolated a lot. It's just like my mind can't focus, it's so anxious and doesn't considering the reading to be important. My theory is it's similar to waking up in the middle of the night when lonely. The mind is searching for dangers from being isolated and alone.

I also notice my urge to buy stuff goes up when I am lonely. Another salve for the pain.


I call bullshit. I stopped reading at the setup: "the researchers had 40 socially-connected healthy human adults spend 10 hours (9am to 7pm) alone, with no social interaction and no other social stimulation (e.g., twitter, email, reading fiction)." All they did was deprive them of social media. I think it's well known by now that this is a source of dopamin.


Additionally, they also forced them to get up in the early morning on the social isolation day, locked them in an unfamiliar room, and gave them close to nothing to do:

On the day of the isolation session, participants arrived at the McGovern Institute for Brain Research, MIT building 46, at 8.15am...Subsequently, participants gave their phones and laptops to the experimenter and were guided to a room containing an armchair, a desk and office chair, and a fridge with a selection of food, snacks and beverages. Participants remained in that room from 9am until 7pm. [1]

It's not clear to me why reading material was withheld. It seems to make it harder to draw conclusions regarding the social isolation aspect.

For the fasting session, they only had to report for the 7pm fMRI session. It strikes me that the type of people with time to participate in an experiment like this likely correlates with people that get up later than 6-7am each morning (as would have been required for the isolation session), but it seems there wasn't any accounting for possible sleep deprivation effects.

In some circles, there's even an expression for a related phenomenon: "skin hunger"

https://globalnews.ca/news/6929793/coronavirus-disability-to...


I feel like they could have come up with a better name.


Interestingly there is a Japanese phrase 'kuchi sabishii' that translates to 'lonely mouth' which means you aren't hungry but want to snack.


I've lived alone my whole adult life. I haven't seen anyone I know since March 8. Doesn't seem to bother me. Guess I'm a freak.


I think there is also difference in the type of people. I feel people on the spectrum are able to empathize over text more than others and so can socialize somewhat more or feel less need to.


People whose chosen occupations require a lot of time away from people they know well -- authors, artists, explorers, prospectors and geologists, traveling musicians and salespersons, fur trappers, truckers for example -- probably cope better with social distancing.

Being isolated for long periods can lead us to difficulty articulating our thoughts well. The 'gears get rusty'. Not so much for authors I'd guess ... but a fading ability to connect no doubt leaves many increasingly frustrated and feeling even more isolated. I'd guess that, for desert travelers, the word 'oasis' meant a lot more than just water.


I wonder what people will think of criminal and justice systems after this (probably nothing). We send people to prisons all the time for extended period without outside contact in an abusive environment between the real nasty criminals and authorities.

Is it really a good idea to send someone to prison for months for a small mistake that many might end up making and getting caught?

Is overusing imprisonment for different types of crimes okay?

A murderer will be fine in a prison since they are harmful for the society but someone stealing food because they couldn't afford any doesn't seem as harmful that they need being locked up.


This... makes a lot of sense. I get hunger cravings even when full when I have those 70+ (rare) or even 55+ (more often) hour weeks.


> when I have those 70+ (rare) or even 55+ (more often) hour weeks

This is likely a different phenomena. You're burning more fuel by working longer. Especially if it comes with less sleep as well.

The brain is quite a fuel-hungry organ and will crave sugars and carbs when stressed. If you're also sleeping less, you're burning more physical energy as well simply by being active longer.

I regularly lose weight during hard weeks unless I compensate by eating more.


This makes sense to me because I dont think the feeling we call hunger is actually our bodies call to eat. I think from an evolutionary origin it is supposed to be a call to action. If that is so, then social isolation could trigger the same feeling.


Eric Berne talked about this long time back in 1964 in his book "Games People Play"


Hah yes the classic "8 stroke American greeting" to prevent "spinal shriveling", good stuff.


Like for many people here, my need for socialization seems to be vastly inferior to the average. However, after years of living very isolated, I can strongly relate to the craving as it's described in this article.


Cravings are satisfied a thousand different ways these days. Social interaction has a lot of competition.


According to a May 25, 2020, WSJ article (https://www.wsj.com/articles/together-review-all-the-lonely-... of Americans felt lonely during the Covid-19 crisis. While this percentage is higher than normal, the issue is not new. 2-3 years ago President Trump brought on a "loneliness" advisor (not for himself, for Americans), and since at least 2018 the UK has a Minister of Loneliness. This is becoming a global issue, including in China, where children are not spending time with their elderly parents the way their previous generations did.
