Do you know the best time to sleep?

How to get better sleep is a science. It is not the best to get eight hours of sleep a day as we generally believe. In fact, scientists have been continuously studying the optimal sleep time and have obtained a lot of unknown data. And some false rumors are scientifically denied, so everyone should have a correct understanding of this issue.

Scientific research shows that the best sleep time is 6-7 hours a day. Maintaining this habit can increase a person's lifespan; sleeping 4 hours or less will shorten lifespan. Understanding these theories can help us arrange our daily routines reasonably and achieve our highest efficiency.

Many young people have a misunderstanding that they can make up for lack of sleep. In fact, staying up late during the week and sleeping too much on weekends will disrupt their normal sleep patterns. Xu Liang also believes that long periods of catching up on sleep will disrupt the normal biological clock, which will directly lead to physical discomfort. "It is not surprising to feel dizzy and headache after sleeping too much." He also added that clinically the most scientific sleeping time is considered to be from 10 pm (no later than 11 pm) to 6-7 am.

"Segmented sleep" is not recommended because night sleep generally has 5-6 cycles from light sleep to deep sleep. It usually takes 50-60 minutes from falling asleep to deep sleep. Only in deep sleep can the brain get enough rest, which is crucial for eliminating fatigue, restoring energy, and improving immunity. Segmented sleep will disrupt sleep patterns and affect brain rest.

But for growing and developing school-age children, adequate sleep is very important. When sleep is deepest, growth hormone is secreted the most. If children do not sleep well for a long time, it will lead to problems with growth hormone secretion, affecting growth and development. Poor sleep at night will lead to lack of energy during the day, decreased memory, and lack of concentration, affecting learning.

Knowing the optimal sleep time can explain problems such as why you get a headache if you sleep too long, why you sleep longer than others but don’t have as much energy as others, etc. In addition, listening to some relaxing music before going to bed can help relax the mind and achieve a hypnotic effect, thereby improving the overall sleep quality, waking up in the morning with good energy and maintaining a relaxed mentality.
