At least 7 hours of sleep is the single most effective thing we can do to maintain a good mental and physical health
If we all slept enough? …our healthcare burden would plummet, we would have better mental health and fewer suicides… our business would be more productive, global economies would be healthier, our roads would be safer and our children would be smarter (they would develop their brains more completely in childhood). We would lower our lifetime risks of common mortality issues, we would have happier relationships and healthier marriages physically and psychologically.
(…) sleep is the very best health insurance policy you could ever wish for- and for the most part, it is democratically and freely available universal healthcare plan; one that is rather painless yet extraordinarily effective.

Early risers have a 12 -- 27 percent lower risk of being depressed than intermediate types.
That is the result of a June 2018 study carried on 32 000 middle-to older-aged women female nurses. The research shows depression risk is not only driven only by environmental (e.g. light exposure) and lifestyle factors (e.g. work schedules) as we might think; but also by the chronotype – the propensity for the individual to sleep at a particular time during a 24-hour period.
Research founds that late chronotypes are less likely to be married, more likely to live alone and be smokers, and more likely to have erratic sleep patterns.
Are night owls doomed to be depressed? Not as long as they get enough sleep, exercise, spend time outdoors, dim the lights at night, and try to get as much light by day as possible.
Still, 4 years of study and 2,581 cases of incident depression show that early chronotypes have lower risk of depression.
Go to bed early and feel better.
