The 8-hour sleep theory may be wrong
8小时睡眠论可能是错的
Recently, an expert pointed out that the 8-hour sleep theory may be wrong. This expert stated that good sleep and the length of sleep are not necessarily related. Sleeping for 8 hours is just a false proposition. Our sleep is calculated according to sleep cycles, with each cycle lasting 90-120 minutes. The so-called 8-hour sleep theory is calculated based on 4-5 sleep cycles. If calculated according to sleep cycles, sleeping for 6 hours or 10 hours is also possible, as it varies from person to person.
近日，一位专家指出8小时睡眠论可能是错的。这位专家表示：实际上睡的好和睡眠时间的长短并没有必然联系。睡眠8小时只是一个伪命题。我们的睡眠是按照睡眠周期来计算的，一个睡眠周期为90-120分钟，所谓的8小时睡眠论就是按照4-5个睡眠周期来算的。如果按照睡眠周期来算，你的睡眠6小时也行，睡眠10个小时也行，这都是因人而异的。
In fact, sleep time is not that important. What is important is to have a regular schedule. For example, many young people who stay up late suddenly decide to go to bed early to catch up on sleep, or go crazy on weekends to catch up on sleep, which may cause problems with falling asleep or sleeping poorly. For our body, if the sleep time is fixed, delaying or advancing it by an hour is just like “jet lag”. To ensure sleep quality, one is to follow a fixed rhythm, and the other is to try not to forcibly interrupt nighttime sleep. The 8-hour sleep has always been just an average, not a mandatory requirement!
其实睡眠时间并不是那么重要，重要的是要有规律，比如很多爱晚睡的年轻人，突然决定今天晚上要早点上床补个觉，或者周末疯狂补觉，都可能会造成睡不着或者睡不好的问题。对我们身体来说，睡眠时间固定了，再推迟一小时或提前一小时都是在“倒时差”，想要保证睡眠质量，一个是要遵循固定的节律，另一个是尽量不要强行中断夜间睡眠。8小时睡眠从来只是一个平均值，而不是一个必选项！
