Does sleeping more shorten life? Does too little sleep affect a person s lifespan?

Who said that a girl who sleeps well will be much better.

That's for sure. The reasons are: first, too much sleep time, blood circulation slows down, for a long time, the heart mistakenly thinks that the speed of blood circulation does not need to be accelerated, still like this at work, because the work of the human organs will also keep the influence of inertia, because the blood circulation is too slow, all other organs of the human body will not be able to get timely and sufficient nutrition and oxygen, in the long run, the function of the human organs will be weakened; Second, too much sleep, the body's immunity will be reduced, immunity depends on the body's immune cells, immune cells are transported to all parts of the body by blood, because of the first reason, blood circulation is slow, when there is a problem in a certain part of the human body, and the immune cells can not rush to the destination in time to deal with the work, so that in the long run, the physique will get worse and worse.

Considering the above effects, do you still doubt that too much sleep is detrimental to lifespan?

Sleeping too much is not good for the brain anyway, and the lifespan generally does not have any effect. Who can have enough sleep all their lives, now that society is so busy, don't think about it.

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.

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.

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

Let me cite some experiments to illustrate.

A study of nearly one million people over the age of 30 found that people who regularly slept less than four hours a day were three times more likely to die within six years than those who slept seven or eight hours a day.

2. A 1983 study conducted by the Naval College of Health Sciences in San Diego found that people who slept 5 to 7 hours a day performed worse in all performance evaluation measures than those who slept more than 7 hours a day. Overall, people who don't sleep well get fewer promotions in their careers, lower pay scales, fewer referrals to work longer, have higher turnover rates, and are more likely to be hospitalized in the course of work.

One study found that women who slept an average of five hours a night were 39 percent more likely to develop heart disease than those who slept eight hours a night.

Another study found that men who slept only four hours on two consecutive nights had changes in their hormone levels, especially a decrease in leptin and an increase in ghrelin, which made them feel hungry and want to eat carbohydrate-rich foods such as cakes, candy, ice cream and pizza. Researchers believe that frequent sleep deprivation is associated with obesity.

Finally, I would like to say that it is true that a small number of people only need 4-5 hours a day, but most people feel this way, which is very embarrassing. And there's no way to train our body to reduce its own sleep needs.

I think you should shorten your sleep time because you want to have more time to work or study, but Einstein should sleep at least 10 hours a day, which means that your work achievements or academic performance may not have anything to do with the length of sleep, but after enough sleep, your attention and willpower will be better, and you can better complete the tasks you want to accomplish.

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.
