Oh the irony, it's pretty late at night (depending on which time zone arjunlall is in). But I'd presume most people on News.YC have a late-night schedule. Why should we "learn to live like an early bird" anyway?
Reduced melatonin production has been proposed as a likely factor in the significantly higher cancer rates in night workers,[26] and the effect of modern lighting practice on endogenous melatonin has been proposed as a contributory factor to the larger overall incidence of some cancers in the developed world.[27] As inadequate as blood concentrations may be in brightly lit environments, some scientists now believe that a person's overnight output of melatonin can be further jeopardized each time he or she interrupts his or her sleep and turns on a bright light (suggesting that using a less-bright nightlight would be safer). Others suggest that such short exposures do no harm.[28]
I couldn't find the words "fitness" or "exercise" anywhere in the article. In my opinion any discussion of sleep habits should include exercise (if I was a doctor that's the first thing I'd ask my patients about). The writer does mention coffee and caffeine, which is another good indicator of potential sleep issues.
I used to work vampire hours years ago while an independent. It was fun in some ways, but waking up at lunchtime made me feel like I missed most of the day. Now I'm up before the sunrise and accomplish more (it's also somewhat necessary in my commuting environment).
Find what works for you, but mind your health (says grandma)!
you should work, when you feel your at your most productive. Day or night shouldn't matter, employers need to understand this when dealing with some jobs (most held by people here at news.yc)
