这个也许和你的问题相关： https://www.vox.com/science-and-health/2018/4/16/17233860/night-owl-chronobiology-sleeping-late-health-risk This past week, researchers at Northwestern and the University of Surrey published a huge study in the journal Chronobiology International of more than 433,000 adults in the UK, who had been tracked for an average of 6.5 years. It found a correlation: Those who reported having a later chronotype (people who are night owls) had a 10 percent increased likelihood of dying compared to people who had an earlier chronotype. And this was true for people of all ages in the study, and for both men and women. It’s always important to note with studies like these that the 10 percent indicates a relative increase in the risk of death. An individual’s actual risk of dying in any given year is small. Of the 430,000-plus subjects in this study, just a fraction — 10,500, or about 2 percent — died within the study period. These results don’t mean an early death is imminent for late risers. But it’s still concerning. As the authors note, “any increase” in risk of death “warrants attention.” The analysis also revealed greater rates of cardiovascular disease, diabetes, respiratory disease, gastrointestinal problems, and psychological distress among evening-type people. 研究的局限性： https://www.popsci.com/night-owl-death/ Unfortunately, the Biobank data only indicated whether someone identified as a morning or evening person, not whether they had a sleep schedule that suited their chronotype. “We know what their preferred time to sleep is, but we have no idea what they were actually doing on a day-to-day basis,” says Knutson.

The association was strongest for psychological disorders (OR 1.94), followed by diabetes (OR 1.30), neurological disorders (OR 1.25), gastrointestinal/abdominal disorders (OR 1.23) and respiratory disorders (OR 1.22). When chronotypes were considered as categories, being a definite evening type was associated with a 10% increased risk of all-cause mortality (OR 1.10, 95% CI 1.02, 1.18, p = 0.012) compared to definite morning types. 这个和你描述的一样： https://www.sciencedaily.com/releases/2016/06/160608174254.htm A new study suggests that among healthy adults with a habitual sleep duration of at least 6.5 hours, late sleep timing was associated with higher fast food consumption and lower vegetable intake, particularly among men, as well as lower physical activity. 另外 Melatonin (褪黑激素) 和睡好觉对于对付新冠病毒也许有一些作用。晚睡早起可能会让你在对付新冠病毒中处于下风。 https://cancerres.aacrjournals.org/content/66/10/5521 Melatonin levels may be closely related to sleep duration. Serum melatonin concentrations have shown to be lower in habitual short sleepers (<6 h/night) than in long sleepers (>9 h/night; ref. 14), and in elderly insomniacs than in age-matched controls ( 15). Under experimental conditions, increasing the length of the night (participants were confined to a dark environment 14 hours per day for four weeks) was associated with both longer sleep duration and increased nocturnal secretion of melatonin ( 16).
注明一下，因为看到不少MM说只要保证睡眠时间，晚睡也没关系，但是他不是这样，他早上要早起上班，每天睡不足6小时。
正确的做法时，你准备点好吃的把。跟他一起熬夜打游戏，熬夜看电影。还有，晚上一两点，真不算熬夜。 我记得，刚来美国时候，有个老美(MD, PHD)还给我看过一篇发表的文章（是CNS级别的期刊），里面认真的描述了人的睡眠，每天只需2-3个小时，其他时间只睡觉就浪费。
至于糖尿病，少吃多运动。
这不可行啊，家里还得至少留一个健康人养娃吧……
一熬夜就吃零食，一吃还没节制，更别说少吃多运动。还是熬夜习惯是根本问题
宋美龄也晚睡，很长寿，只要早上也有条件晚起，就没大事。
每个人生物钟不同，不要施加不必要的压力。
推荐你老公看这本书：Why we sleep. UCB 专门研究睡眠的教授写的，论据全部基于科学实验的证据，符合你的要求。如果你老公认真看，应该会改变的。 https://www.amazon.com/Why-We-Sleep-Unlocking-Dreams/dp/1501144316
看医生吧，随便转个微信文章反正别人给我看我是不信的
N多年前，我的很多男性同学和朋友圈的野鸡总结，晚睡晚起晨勃减弱或没有，早睡早起晨勃增强或恢复。。。
他要早起上班，不能保证睡眠时间，通常不足6小时。不然我也不管他了，还少了多少矛盾
太谢谢啦
谢谢MM。 可惜健身这事对他比早睡更难，哎。
这话说的...lzlg怎么可能像宋美龄那样养尊处优，晚睡晚起天天自然醒，普通人都要早起上班赚钱的
我知道有些人一到晚上就特别精神，我自己就是，哪怕睡到床上也半天睡不着
听两个朋友说养狗可以改变，因为狗狗早上要出去尿尿，还要遛狗，不然他会一直刨门让你没法再睡
身体健康不在于每天非要睡8个小时以上，在于有规律的饮食和锻炼。吃和睡眠都需要节制。
GOOGLE “nature circadian” 会看见图，简明扼要有说服力。
这个研究人员每天睡2/3 小时试试看？
谢谢MM
关于睡眠剥夺的研究有很多，楼主可以搜一下；幻听幻视等在 极少睡眠 情况下都是会发生的，当然，还有很多其他side effect
每周一本书，每天睡三小时，很多人这么做。 就是晚上12点，1点睡，第二天4点起来去锻炼。 但我觉得每周一本书，能坚持十多二十年，还是对自己很有帮助的。

然后白天 中东人呼呼大睡
反正中东人都靠社会救济， 也不需要工作！！
为啥我们中国人不能学习学习人家中东人啊，
看看人家中东人过的多舒服啊！！
不需要工作， 靠社会救济， 也能活的很好啊！！
再看看中国人， 一个个累的面黄黄的！！
可悲！！
