As the saying goes: 'When a person sleeps three times, his life is thinner than paper', what does it mean? Not a superstition, it is recommended to understand

Sleep is one of the most basic physiological functions of the human body. Through sleep, people can rest and restore their energy. Nearly a third of life is spent sleeping. When you wake up, your body and brain will recover better.

Poor sleep habits play a decisive role in human health. Almost 20% of heart disease is caused by lack of sleep. When the human body ensures enough sleep, it will have enough energy and perseverance to complete the day's work tasks the next day. If you don't have a good rest at night, stay up late and have insomnia, your mental state will be relatively depressed the next day.

The 8 hours of sleep that is recognized as the best, is "pseudoscience" or fact?

Eight hours of work and rest are considered the healthiest, but research has found that Chinese citizens' sleep time has been reduced from eight hours to 6.5 hours, with 60 percent of people not falling asleep until 11 p.m.

Most of them didn't go to bed until 1am, and some got up before 7am, so the average sleep time was less than 6 hours, and only 18.79% actually got 8+ hours.

According to different brain wave components, sleep experts divide the sleep cycle into five stages, namely: falling asleep, light sleep, deep sleep, deep sleep, and rapid eye movement. It usually takes 90-110 minutes to complete a sleep cycle , depending on the person, the duration of the cycle will vary.

Generally speaking, as long as the sleep time is a multiple of 90 minutes, and 4-5 sleep cycles are completed every night, the quality of sleep can be greatly improved.

The human body has a normal circadian rhythm that requires rest at night and movement during the day. Circadian rhythms are associated with changes in endocrine hormones, especially a specific hormone called melatonin.

It is secreted at 2-3 o'clock in the evening, can regulate the sleep of the human body, and has antioxidant effects. Anti-aging, anti-aging and anti-cancer effects, staying up late at -3 o'clock will seriously affect the secretion and health of melatonin. In addition, in the definition of sleep time, the currently recommended optimal sleep time is 7-7.5 hours.

Domestic and foreign studies have shown that if the sleep time is less than 7 hours or more than 9 hours, the life expectancy will be shortened. There is little effect on the patient's final lifespan if they sleep between 5-7 hours, but if they sleep less than 5 hours it can lead to serious health problems.

Sleep is also learned, and there have been many studies on sleep since ancient times. "If you don't want a short life, don't sleep three times." Some people say, "If you sleep three times, your life is thinner than paper." Literally it is not difficult to understand. This sentence says that three sleeps are harmful to health. So which three types of sleep are specifically referred to?

As the saying goes: "When a person sleeps three times, his life is thinner than paper", what do you say? Not superstition?

【Sleep after dinner】

"Three full and one down" every day is not conducive to maintaining health, and will also allow diseases to come to you. Therefore, the most taboo is to "sleep after a meal" and not lie down or lie down on the sofa immediately after a meal, which is not conducive to digestion and easily induces gastrointestinal diseases.

It's easy to get sleepy after a meal, but don't go to bed right away. "Sleep after meals" will not only affect digestion, but also affect sleep quality, which is beneficial to the skin.

【Sleep late】

Many people have the habit of sleeping in, especially on weekends and holidays. They often sleep until noon, but this is not recommended. Traditional Chinese medicine believes that lying down for a long time hurts Qi, and morning is the best time for Yang Qi to grow. At this time, sleeping late will affect the stretching of yang energy and hurt the body.

In addition, sleeping in late can also cause irregular work and rest, disrupting the biological clock. Due to sudden changes in sleep habits, the body can lead to hormonal disturbances, depression or headaches.

In addition, sleeping in late can also make people miss the golden period of eating breakfast. If you skip breakfast, overeating midday can also impair bowel function, leading to chronic gastritis or indigestion.

【Headsup】

When winter comes, the temperature drops and the surrounding winds are biting. Especially at night, the temperature will be lower than during the day. In this way, many people like to bury their heads in the quilt to keep warm, which can not only avoid the problem of cold head, but also solve the problem of cold nose after getting up in the morning.

Such bad habits are wrong. Sleeping in the quilt, the oxygen and carbon dioxide needed by the human body cannot be exchanged in time, and are hindered by physical factors, which can easily cause physical diseases such as breathing difficulties.

Especially for young children, their lung development is not perfect, which is weaker than that of adults. If they have such a bad habit, it is easy to cause poor breathing and gas exchange in the lungs, leading to lung function diseases.
