吃饱了撑的研究这个，故意不睡觉的就那么几个。大部分不是睡不着就是没的睡

2.3万！🤣

明显不靠谱，晚睡多数会时间不足，睡眠不足当然的下降了。

怎样才算越早睡越好？我在纽约12点睡，可是这时候才相当于洛杉矶的9点钟就睡了。那我是睡得早还是睡的晚呢？

那我熬夜到两点睡觉，不是相当于早正常作息的人19、20个小时睡吗？那我肯定是最聪明的人类。

关键是“规律性”

老毛一般凌晨睡觉，中午才起来。

起点高往下掉的空间本来也比别的多，100分有100空间可掉，10分最多也只能掉10分

那些极端明锐的人大部分都是夜猫子

1. Chronotype vs. Social Jetlag
Chronotype itself (being a night owl) is a natural biological variation.
The bigger issue is circadian misalignment (social jetlag), when someone’s internal clock doesn’t match their external obligations (e.g., work or school schedules).
The authors note:
“If an individual can live according to their own biological clock, the chronotype will reflect the circadian rhythm. However, in case of circadian misalignment leading to social jetlag, this factor could also partially explain the association, rather than chronotype itself.”
This means the harmful effect may not come from being a night owl per se, but from being forced into schedules that don’t fit their body clock.
2. Why highly educated people were most affected
The study only found significant cognitive decline in highly educated participants, who are more likely to work rigid 9-to-5 jobs.
By contrast, people in lower or middle education groups may have jobs with more flexible hours, which allows their work time to align better with their chronotype.
The authors suggest this flexibility may protect them from the negative effects
3. Implication: Matching schedules could help
While the study didn’t directly test flexible schedules as an intervention, the discussion strongly implies that:
If night owls could align their work and social lives with their natural rhythm, the risk of cognitive decline might be reduced.
The authors even recommend:
“…the promotion of flexible work schedules, particularly among highly educated individuals.”
所以夜猫子不是问题， 问题是如果夜猫子可以根据自己的生物钟作息， 就没那么严重。别武断的拿去给自己孩子说让他们早睡哈。。。。

熬夜加班那是熬夜，熬夜玩游戏那叫晚睡，对健康影响天差地别。玩游戏猝死的有几个？

这项研究可能不包括职业吧,我的一个亲戚是农民不吸烟，不喝酒，早起晚归，应该说作息时间很规律，晚年也得了阿尔兹海默症。我认为，该研究依然缺少普遍性。
