What is the relationship between sleep time and length of life?

The younger the person, the longer the sleep, and the older the person, the less sleep time. Elementary school students sleep 10 hours, adult men and women sleep 8 hours, and older people sleep 6 hours. Sleep is not widely said to be the length of time, sleep is mainly said to be quality, if you sleep without quality for a long time, it is useless.

What is sleep quality? That is, fall asleep quickly and don't dream, and it doesn't matter if you usually dream less, as long as you don't dream often. The quality of sleep is very important, if you often fall asleep and can't sleep, you often dream when you fall asleep, and you get sick after a long time, it is very important for people to live a long life and have a good sleep.

Of course, people's normal sleep time is 8 hours, but it can reach 7 hours, and the sleep time also has certain requirements, such as the best time to sleep at night at 10:30, so as to ensure that you can enter deep sleep before 11 o'clock, so as not to bring harm to the body because of staying up late, it can be seen from the meridian flow chart of traditional Chinese medicine that sleep plays a very critical role in the repair and prayer of our body, such as gallbladder, liver, lungs, etc. If you miss this time, then it will cause harm to your body.

Ensuring adequate sleep also has an important role is to avoid fatigue, at present we are concerned about the harm caused by staying up late, but the damage caused by fatigue is also far-reaching, more and more young people are experiencing sudden death, in fact, it is directly related to fatigue, on the one hand, because of too long working hours, on the other hand, due to the short rest time at night and poor sleep quality, these are the factors that cause excessive fatigue, and the small problems that seem to be fatigue are often the key factors that lead to sudden death.

It takes about 6 to 8 hours, and you go to bed at 10 p.m. every night and wake up at 6 a.m. for the best rest. Especially in winter, it is better to go to bed early and wake up late. In addition to the body getting enough time to rest, the temperature is relatively high when you wake up late.

It will not make the body feel cold or runny nose, the body has undergone a night of rest, full energy and good blood circulation, which will make our ** more shiny, elastic, and look more hydrated, while the body's toxins and metabolic wastes are eliminated from the body, and will also make our body stronger.

At least 6 to 7 hours a day, depending on the person. Sleep is no less important to a person than eating, or in other words, eating is a material meal, sleep is a spiritual meal, and the key is a person's self-regulation ability. A person who does not eat for several days may not starve to death, but may have a nervous breakdown if he does not sleep for several days in a row.

Maintaining a good night's sleep is first and foremost about dinner, not overeating, not doing strenuous exercise before going to bed, and not overthinking. At around 10 o'clock in the evening, you should tell your subconscious mind to go into sleep immediately, or drink a cup of yogurt and soak your feet before going to bed, which will help your body quickly fall asleep.

Nowadays, my friends pay less and less attention to sleep, and they are gradually shortening their sleep time, and they are constantly busy every day. If the body does not get a good rest and repair, it will cause the body's immunity to decline and various symptoms will appear for a long time.

Sleeping at nine o'clock is not old, sleeping at ten o'clock to protect the brain, and eleven o'clock hair falls out.

There will be an impact. Short sleep time and lack of sleep have a lot of harm, because short sleep time, if you can't recover your energy and physical strength normally, it will lead to a decrease in the secretion of neurotransmitters in the brain. Growth hormone and melatonin are secreted during sleep, if the sleep time is short, it will cause a lot of growth-promoting hormone secretion to decrease and inhibit growth, so that children in the process of physical development become dwarfism or short stature, and will also cause malnutrition.

In addition, due to the lack of certain neurotransmitters, the immunity is narrow, and it is easy to develop infectious diseases, which will also cause the constriction of blood vessels, the acceleration of arteriosclerosis, the emergence of cardiovascular and cerebrovascular diseases, and the occurrence of malignant tumors in severe patients.

A healthy, good night's sleep depends on good, enough deep sleep, as well as adequate sleep time and a complete sleep structure, and everyone needs different sleep time, short sleep time may be seen in normal people, and there may be certain sleep disorders. Some normal people have a short sleep gene, that is, a sleep talent, even if they only sleep 4-5 hours a day, it is enough to ensure sleep quality, and there will be no lack of energy, mental power, and physical strength during the day. Some elderly people will sleep shorter, but it will not affect their daily life, and there are no other uncomfortable symptoms during the day, which is a normal aging process and there is no need to worry.

Others have a short sleep time because of the social environment and the demands of certain jobs, such as health care workers on night shifts, emergency workers, or police officers. There are also people who get short sleep because of mood disorders, such as depression, lack of daytime sleep stress, such as not exercising enough, eating coffee, alcohol, and other foods. In conclusion, there are many factors that cause short sleep duration, and it needs to be analyzed on a case-by-case basis.

The purpose of sleep is to restore mental and physical fatigue, as long as you have enough energy to complete work, study and life during the day, there is no need to worry about whether the sleep is long or short.

It needs to be well conditioned, such as combining work and rest during the day, participating in cultural and sports activities, exercising, and not taking too long a nap. Sleep on time at night, go to bed early and wake up early, don't drink coffee before going to bed, and don't drink strong tea. Appropriate under the guidance of a physician, you can use drugs to calm your sleep, take them as needed, use them intermittently, and do not become addicted.

In addition, find out the exact **, whether it is a brain disease, a physical disease, or an emotional illness that interferes with the short sleep time. Treatment, good treatment, plus symptomatic treatment, can receive good results.

It can affect a person's life because it is not good for our physical health, it is not good for our physical development, and it will also reduce our resistance, and it will also reduce our immunity, so we must pay attention to this problem.

For different people, the sleep time is different, but the long-term lack of sleep, staying up late is easy to endocrine disorders, the symptoms of fire and acne, and the excessive mental burden can make the body in a sub-healthy state.

Sleeping too little can affect a person's lifespan because sleeping too little can affect physical health and can lead to the occurrence of various diseases.

The length of sleep will have a certain impact on a person's lifespan, but there is no direct proportional relationship. In addition to sleep time, a person's genes, physical fitness, and other factors also have a lot to do with the length of their lifespan.

The best time to get a good night's sleep is between 9 and 11 p.m. During this period, the body's energy decreases, the reaction is slow, and the thinking slows down, which is conducive to people turning to slow-wave sleep.

The best time to sleep is between 11 p.m. and 6 a.m., and 11 p.m. to 3 a.m. is the time to sleep**. At this time, the metabolism of the liver is most vigorous. If you miss this sleep** time for a long time, sleep disorders will occur, leading to physical dysfunction.

Those who prefer nightlife or have to work overtime and often fall asleep at 1 or 2 o'clock in the morning are the precursors of disease and aging, although not for the time being.

With the general acceleration of people's pace of life, sleep deprivation has become a common phenomenon among urban people today.

How the length of sleep determines longevity p> Everyone's personality is different, and so is the amount of sleep needed.

The average adult is suitable for 7-8 hours of sleep, sleep research experts call people who sleep 6 hours or less "short sleepers", such as Edison and Thatcher, people who sleep 9 hours or more are called "long sleepers", such as Einstein, many creative people in the field of science and art are envious of long sleepers.

So if you always need to sleep for more than 9 hours to be refreshed, it may not be because you are lazy, it is likely that you are a long sleeper, and you do not need to deliberately sleep less in order to be like others.

Different ages need different amounts of sleep.

These numbers are just average time, not necessary to measure how good or bad sleep is, and can range from less than 3 hours to more than 10 hours if you want to get quality sleep.

We will find that with the increase of age, the time of sleep will be less and less, so we should also adjust the time of sleep according to the change of age, the best sleep time of different age groups is also different, we should ensure scientific sleep according to our age, so that it is more conducive to our health and longevity.

What is usually related to sleep time? This is a question that many people are confused about, sleep usually affects a person's mental state! About, Is there a relationship between sleep time and longevity? What factors are associated with the length of sleep? I'll answer them all for you!

What factors are related to sleep duration.

The length of sleep is usually related to age, circadian rhythm, self-awareness, physical health, human lifespan, illness and other behaviors. Usually 8 hours of sleep a day is enough, and studies have shown that the optimal sleep time is different for different ages.

Is there a relationship between sleep time and longevity.

There is a relationship between sleep time and longevity. One study found that sleeping too long is more likely to shorten life. Studies have shown that people who sleep more than 8 hours have a 20% higher mortality rate; People who sleep less than 5 hours and more than 8 hours are at risk of increased mortality.

People who slept more than 8 hours a night were 30% more likely to have a stroke. Scientists say there is a link between sleep and longevity, but it's unclear whether it's too much sleep that causes short life or something else** that causes drowsiness.

Survey and analysis of sleep time in various countries.

According to a report in Sweden**, researchers in the country tracked 70,000 Swedes aged 45 to 83 from 1998 to 2012 about their sleep habits and sleep duration. During this period, 1.45 million people died. Sail results showed that those who slept 7 hours outlived 1 year longer than those who slept more than 8 hours and slept less than 6 hours.

British researchers found that people who slept less than 6 hours had a 1-fold increase in the incidence of metabolic syndrome. It has also been found that lack of sleep not only makes people physically tired, but also makes it easy to gain weight. The volunteers slept only 5 hours a day and gained 1 kg after 5 consecutive days.

Sleep deprivation comes at a cost, with at least 4 ills, namely low productivity, ease of work accidents, increased risk of diabetes, and ease of aging. Many people know that alcoholism and smoking are chronic suicides, but many more don't know that overeating and sleep deprivation are also chronic suicides. According to medical experts' estimates, long-term severe sleep deprivation can shorten a person's life expectancy by about 15 years.

Researchers in the United States have found that after a good night's sleep, many people wake up feeling refreshed and energetic. The reason is that during sleep, the body's essence and energy are kept in the five organs, the five bodies are comfortable, the qi and blood are harmonized, the body temperature, heart rate, blood pressure decreases, and the respiratory and endocrine are significantly reduced, so that the metabolic rate is reduced, and the physical strength can be restored. The brain consumes the least oxygen during sleep, which is conducive to the storage of brain cells, the recovery of energy, the improvement of brain power, and the natural enjoyment of longevity.

Of course, not enough time to rest, that is an overdraft of life.

Sleep does not have to be much, the key is the quality, if the quality of sleep is high, then even if it is 4 hours, the next day can still be a hundred times more energetic, on the contrary, no matter how much sleep you sleep, it is not necessarily good Adults should be in 6 9 hours. For example, going to bed at 10 or 11 o'clock at night and getting up at 6 or 7 o'clock in the morning can enable people to maintain a relatively stable biological rhythm with several other biological rhythms, which is beneficial to the human body and mind The standard of high-quality sleep: 1) Fall asleep quickly, fall asleep in about 10-20 minutes; 2) Sleep deeply, breathe deeply, and not easily wake up; 3) No or very little waking up at night, no dreaming phenomenon, forgetting dreams soon after waking up; 4) Wake up quickly, wake up in the morning and be in good spirits; 5) Clear mind during the day, high work efficiency, not sleepy and tired.

The average adult is suitable for 7-8 hours of sleep, sleep research experts call people who sleep 6 hours or less "short sleepers", such as Edison and Margaret Thatcher, people who sleep 9 hours or more are called "long sleepers", such as Einstein, and many creative people in the fields of science and art are long sleepers.
