As the saying goes, "spring sleepiness, autumn and summer nap", every morning when you wake up, do you feel like you have slept enough? Some people fall asleep when they touch the pillow, but wake up feeling groggy and weak...... Scientists believe that these "junk sleeps" that "sleep equals no sleep" are even more terrible than insomnia.

打呼嚕不代表睡得好，睡眠暴力也很糟糕，睡過頭可能睡出高死亡率……曾有日本研究調查顯示，每天睡7小時的人可以活得最久，而睡得愈多死亡率就愈高，如果每天要睡9個小時以上的人可能身體有毛病。作為生存的根本，睡眠與我們的生活息息相關。

Over the years, sleep experts around the world have been looking for a sleep rule that is truly suitable for humans, and in addition to the "secret of the biological clock" that won the Nobel Prize in Physiology or Medicine, scientists have made many different discoveries on the road of sleep research.

For example, according to the National Institutes of Health, people who get 6 hours of sleep per night respond best, and if they only get 0 hours of sleep every night for 0 weeks, they are forced to "open the night" for two nights. The amazing thing about the study is that people who sleep 0 hours a night think they have enough sleep, but in fact, their physical functions and cognition deteriorate unconsciously, and although they do not feel sleepy, their functional response will become worse and worse. Sleeping too little is not good for your health, and sleeping too much is not good for your health.

On World Sleep Day, the concept of "junk sleep" was investigated by the British Sleep Council, which once again aroused heated discussions in the academic community. "JUNK SLEEP" CORRESPONDS TO "JUNK FOOD" AND REFERS TO THE PROBLEM OF INSUFFICIENT SLEEP TIME AND LOW SLEEP QUALITY.

Is your sleep like "garbage"? What is the right amount of sleep? What are the dangers of sleeping too much? Don't worry, you'll know after reading it!

What kind of sleep is like "garbage"?

(1) Falling asleep while watching TV, listening to music, or playing video games;

(2) Forcing yourself to go to bed and get up in the morning according to the "time point", and the time "point" is always adjusting;

(3) After waking up naturally, thinking about "lying in bed" again, forced to prolong the sleep time;

(4) Don't sleep at night, make up for sleep during the day, and make up for sleep on weekends;

(5) High work pressure, need to work overtime at night, fall asleep immediately after high-intensity work, etc.

What is the right amount of sleep?

Sleep has a certain health standard in "time", the British Sleep Association recommends that the best sleep time is 8~0 hours for infants aged 0~0 months, 0~0 hours for children aged 0~0 years old, 0~0 hours for children aged 0~0 years old, 0~0 hours for children aged 0~0 years old, 0~0 hours for adolescents aged 0~0 years old, 0~0 hours for adults aged 0~0 years old, and 0~0 hours for adults over 0 years old.

The director of the Department of Psychiatry and the director of the Sleep Medicine Center of the First Affiliated Hospital of a university said that the more sleep "time" the better, and it should be moderate. Numerous studies have shown that excessive sleep increases the morbidity and mortality of disease, especially in the elderly population.

What are the dangers of sleeping too much?

(1) Excessive sleep induces diabetes

The normal sleep time is 3-0 hours, and more than 0 hours becomes too long sleep, and some studies have found that too long sleep is easy to induce diabetes. Studies have shown that if you sleep more than 0 hours, the risk of diabetes increases by more than 0 times.

(2) People who sleep too long will become stupid

If you sleep for too long, you will become lazy, and because you sleep for a long time, the brain will rest for too long, which will lead to a decrease in the cell activity of the brain, because if you sleep for too long, the nerve cells will be inhibited for a long time, and over time, it will affect intelligence, lead to memory decline, and cause people to become more and more stupid.

(3) Prone to death

Relevant data show that people who sleep 9 hours a day have the lowest mortality rate, less than 0 hours will increase the chance of death, and more than 0 hours will also increase the chance of death. And the results of this statistic do not discriminate between men and women. Therefore, the more sleep is not the better, everything is the opposite, less is harmful to health, and more will also be life-threatening.

(4) Weight gain

Researchers have studied the increase in weight and fat among adults in Quebec over a period of 6 years. They found that people who slept too little and too long each night gained more weight than those who slept seven or eight hours.

During the study period, people who slept 25 to 0 hours per night were 0% more likely to gain 0 kg of body weight, even with controlled food intake and increased physical activity. Therefore, these results underscore the need to consider sleep duration as a factor in weight gain and obesity, the researchers wrote in the study.
