Why is there a big difference in the need for sleep among peers who have similar living conditions?

Sometimes it's a habit, and it has something to do with the quality of sleep, I haven't been to work for a while, I have to sleep enough for 10 hours a day, if I get up one day early for an hour or two, I'm dizzy all day, but now I'm at work, I get up at seven o'clock every day, go to bed at 11 o'clock at night, and don't have to rest at noon, and I'm still very full of energy.

Insomnia is often a combination of poor sleep diathesis and learned insomnia factors. For example, major and small events in life that cause mood swings, or excessive dependence on mobile phones, can lead to insomnia. For the vast majority of insomnia sufferers:

Each additional hour of sleep within the normal range significantly reduces the risk of depression, hopelessness, nervousness and restlessness. In today's high-pressure work and life, insomnia is a relatively common phenomenon, and the proportion of young people represented by the post-90s generation is very high. According to the data released by a health platform, it is

Adults have people who sleep for six hours, have enough energy every day, and some people who don't sleep for ten hours feel that they haven't slept enough, which is related to the physical fitness, slow metabolism, poor physique, shallow sleep, insufficient cerebral blood supply, and people with high blood lipids love to sleep, and always feel that they don't sleep enough, dizzy, people with good physique are easy to fall asleep, sleep quality is high, although the sleep time is short, but it has met the needs of the body. It is normal for adults to sleep 6 to 8 hours a day. If you have too little or too much for a long time, you need to go to the hospital for examination.

Because sleep habits are different, sleep quality is different. If you want to sleep shorter, you need to consciously adjust it. Sleep time can be completely adjusted, there is a saying that the more you sleep, the more you want to sleep, as an adult, generally 6 hours is enough, and you can be very awake during the day.

Adjust the sleep time at night, first of all, you can't sleep during the day, go to bed early at night, then set the alarm clock, get up early in the morning, no matter how tired you are in the morning, you must get up, at most a week, and the sleep time will be adjusted.

So many people sleep differently, some people like to suffer, some people like to please, of course sleep is different, some are insomnia and some are sleep of course are different, insomnia and sleep are both diseases, they have not adjusted well, they must master their habits and exercise rest.

There are indeed many such people in life, who can be active in the circle of friends at two o'clock in the morning and the morning running group at seven o'clock in the morning at the same time. Even if you only sleep a few hours a day, you can move bricks all day, which makes us who rely on coffee to sleep at 10 o'clock every day to live really envy. In addition to insomnia, it is also possible that there is a lack of sleep.

You don't need to sleep too much to be able to stay refreshed all day, which is the "innate advantage" brought by genes. Scientists have discovered a gene, ABCC9, which can determine the duration of sleep, which may partly explain why some people can work energetically after sleeping only 4 hours a night for a long time.

External factors, such as the degree of time and leisure, (work is busy, do you have time to sleep, the exam is about to begin, you have to fail the course, do you still have time to sleep). Internal factors such as the degree of sleep (the deeper the sleep, the less sleep time is required), the degree to which the individual pursues sleep.

There is a saying that if you can't wake up 30 years ago, you can't sleep after 30 years, maybe it's because of your body. Human beings have to nourish themselves when they reach a certain age, and all organs of the body are slowly going downhill, and everyone's physical fitness also has a certain impact, so we have to exercise our bodies after work to achieve a combination of work and rest, and the body will be great.

Introduction: In fact, the older the elderly, the less time to sleep, this statement is actually unscientific, the normal elderly physiological need of sleep time is the same as that of young people, are to ensure that within 7 or 8 hours. Some elderly people will feel that the older they are, the less time they need to sleep, this is because they are not less required for sleep, but in the process of sleeping, it is easy to be carried out by external factors, once sleep is interrupted, it is difficult to enter the state of sleeping again, and some elderly people will also go to take a nap at noon, so this time can also be regarded as a full day of sleep.

If the elderly often lack sleep, the impact on the human body is also very large, so we should pay more attention to the problem of sleeping, if there is a long-term sleep disorder, it will make the whole body function disordered, resulting in hypertension, heart disease and other diseases, because the elderly are likely to suffer from some chronic diseases, then there is a vicious circle of the body may cause a vicious circle of the body, which is very unfavorable for health, and if the sleep is not good, it will also have a certain impact on the concentration and memory of the elderly. It will make the aging of the elderly more serious, and it will also induce some psychological problems, resulting in obesity.

It is very important for the elderly to ensure a good sleep quality, so it is necessary to create a good sleep environment, to make this environment more comfortable to reduce the interference of light and noise, mainly to improve the quality of sleep, and usually to maintain a good attitude, to avoid emotional tension and anxiety or thinking too much, to relax the mood, usually to adhere to regular physical exercise, which can help people enter deep sleep and reduce the number of times they wake up.

Finally, the elderly can drink a glass of hot milk before going to bed, because there are some ingredients in the milk that can help calm down, and drinking a glass of milk can make the elderly relax physically and mentally and fall asleep as soon as possible.

Because a person's sleep is controlled by the human brain, the brain's control over sleep will gradually weaken as we age.

Because there are many older people who are very poor in physical fitness and are very prone to illness, this situation will occur.

Because the older you get, the worse your health will become, and then you won't be able to sleep, so the need for sleep time will become less and less.

It is normal to need less sleep as you get older, because it is people's experience and a fact that sleep duration changes with age.

In general, the younger you are, the longer and more often you sleep. This is because children are not yet mature in the growth and development stage, whether it is the brain or the body, and need more sleep time to ensure that the needs of physical growth and growth are early, which is determined by the law of human growth and development. As we age, our bodies develop and our nerve cells decrease.

From the age of 30 onwards, nerve cells decrease every year. Medical studies have shown that from the age of 30 to 80, people lose 100g of brain weight.

Sleep is an activity in the brain, and due to the decrease in nerve cells, it naturally affects the time of sleep.

Most young people with insomnia complain of difficulty falling asleep, but once they fall asleep, they sleep well. On the other hand, the elderly who suffer from insomnia do not have difficulty falling asleep, but due to the disease and physiological changes, the number of awakenings throughout the night and in the early morning is increased. According to research, young people wake up at night an average of 21 times, and older people wake up twice as often as young people at night.

It can be seen that the sleep of young people after falling asleep is relatively stable, and the sleep of the elderly is mostly very shallow, and they wake up frequently in the middle, and sleep is in an unstable state throughout the night, making the sleep fragmented.

Generally speaking, it is mostly due to the slowing down of metabolism in older grades, so the vitality of brain cells is reduced, that is, various functions are reduced, and the time required to repair the function of brain cells through sleep is reduced, of course, there are individual differences. Second, with the increase of age, the body's metabolic capacity declines, the basal metabolic rate is also gradually decreasing, the functions of various organs are also gradually decreasing, and oxygen consumption and oxygen demand are gradually decreasing. The amount of activity is also decreasing, and the secretion of various hormones in the body is also decreasing, so there is less sleep time.

In their opinion, there are uncertain factors in everything, so the elderly generally worry more, and the second is physical factors, people don't do it when they are old.

<> calcium deficiency is common in older people. A lot of backache. It's all caused by a lack of calcium!

The human body is a whole day, and the smallest unit of the human body is the cell! As we age, our cells slowly decrease and our ability to repair as we age! A considerable number of people, especially after the age of 60, have a slow decline in many functions of the body, especially in terms of immunity.

We know that many times we are tired after repairing in sleep, the point is that in middle age, you must not overdraw your body, on the contrary, middle age is the best time to take care of your body, and to maintain your body is to buy an insurance after 20.

First, physiologically speaking, as we age, our body gradually develops and improves, and our nerve cells decrease with age. Sleep is an active phenomenon of the brain, due to the decrease of our nerve cells, as we get older, a hormone secreted by his body gradually decreases And this hormone is related to the length of sleep time So older people (especially the elderly) sleep less People over 50 years old are prone to sleep disorders The sleep time of a person's life is decreasing with age, and the infancy sleeps more than 20 hours a day, and the older the person, the less time he sleeps, it may be that the rest of his life is getting shorter and shorter, so he especially cherish the time he is awake.

As they get older, their body needs will decrease, so their sleep will also decrease. Because some older people have less space to use their minds, they also get less sleep.

This is because as we age, many body organs are less sensitive, and we need less and less rest time in our daily life, which is why we are prone to illness when we get older.

I think it may be because my spirit is not very good, so I wake up for a long time, and I don't sleep too long and I don't feel sleepy.

When a person sleeps, all the vital activities of the body are slowed down, and they are in a state of rest, recovery and reaccumulation of energy. However, due to the aging of tissues and organs and the deterioration of functions, the elderly have a low level of immunity and a reduced ability to resist diseases. On the other hand, the pineal gland in the brain, which coordinates the diurnal relationship, shrinks, and the sleep rhythm is disrupted, making it difficult to get enough sleep. Poor sleep and the body does not get enough rest, which in turn affects the immune function and weakens the immune system.

It can also affect the health of the brain, making memory loss and cognition of things slow. Geriatric diseases appear gradually.

Mainly because I am older, my organs in all aspects are not as sensitive as before, and my mental aspect is not as good as before, so I feel less.

Because I am older, there are more trivial things in life, which occupy most of my life, and I have no time to continue sleeping, and my body is very accustomed to this kind of life and rest.

Because the body function of the elderly has undergone a great change, there are fewer sleep requirements, which is why the elderly have poor sleep quality.

Because the older people are, the less sleep they have, and they often think about what they don't have, which will make their brains unable to enter a dormant state.

Because when we get older, many organs are relatively well developed, so we don't need to sleep to rest.

Because the biological clock of older people will become shorter, so as they get older, they will have less time to sleep.

During the period from birth to aging, the amount of sleep time is gradually decreasing. Many people think this is normal, but it's not because you get older that you need less sleepIt is because the metabolism of the elderly is relatively slow, brain degeneration, diseases, anxiety and other conditions will cause the elderly to sleep less. In fact, the elderly should also have enough sleep time like us young people.

1. The reason for the slow metabolism of the body With the increase of age, the various organs in the body are gradually weakening, and the body is depleting slowly. Therefore, the metabolic rate will also drop rapidly, so the sleep time will be reduced accordingly. According to scientists' research, the elderly should maintain some sleep time with the young, and sleep enough for 7-8 hours a day before the body will have energy.

Second, the cause of brain and body secretion The sleep characteristics of the elderly are: falling asleep quickly, lying down to fall asleep, easy to wake up, and waking up early. Because the older you get, the faster the brain degenerates, because the pineal gland in the brain gradually degenerates.

Because the pineal gland helps the body regulate the relationship between day and night, the sleep system is disordered, and it is difficult to have good sleep quality. And the older you get, the less melatonin your body secretes, and melatonin is a substance that promotes sleep, so the older you are, the more difficult it is to get enough sleep.

3. Disease and mental causesWith the growth of age, the elderly will have various physical and psychological problems, and common cardiovascular diseases and Alzheimer's diseases and other diseases in the elderly will affect sleep; The elderly are particularly prone to feelings of loss, depression, nervousness, and so on. These emotions can affect sleep, and it is more difficult for the elderly to fall asleep due to frequent disturbances such as cramps, dreams, and waking up in the middle of the night while sleeping.

Sleep is very important for people of any age, lack of sleep time will reduce our body's immunity, and the body will have many diseases, so having enough sleep is very important for good health. The elderly should maintain a peaceful mind, have a regular daily routine, and create a warm sleep environment if it is difficult to fall asleep.
