The 8-hour sleep theory may be wrong
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.
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!
