I was mixing up correlation and causation, which is also some kind of irony my tired/jet lagged brain is too foggy to work out.
Correlation has no causation direction so you are absolutely right.
What I meant is that ED can be caused by hypertension, so if you get ED you should start checking your blood pressure. AFAIK chronic bad sleep doesn’t CAUSE high blood pressure in the same way. Not sleeping well will elevate your blood pressure, but not make it chronically worse. Put differently, if you have trouble sleeping at night, that doesn’t mean you have elevated risk of high blood pressure when rested.
But yeah, if you have high blood pressure (as I do), getting good sleep makes a huge difference in your numbers.
