Why do you need less sleep when you get older?

Normally, we need eight hours of sleep a day to meet the requirements.

However, for older people, the amount of sleep per day is getting shorter and shorter, not reaching the level of eight hours a day.

The reason why the older you get, the shorter the sleep time is, is due to the following reasons:

1. Aging of the body.

As we get older, our organs gradually age. ......This results in the following aspects:

For one, the body's metabolism slows down.

Second, hormone secretion levels decrease.

The direct result of this is the shortening of the body's sleep time.

2. Life factors.

After old age, people's living conditions have changed greatly with the arrival of retirement.

I used to be busy going to work, but now I walk around the park every day. ......This results in the following aspects:

For one, the amount of daily activity is greatly reduced.

Second, there is less contact with society, resulting in a sense of loss and loneliness.

The above problems will affect the sleep state of the elderly.

3. Influence of environmental factors.

As you get older, you become sensitive to your surroundings. Once there is noise and other influences, it is easy to affect the sleep of the elderly, resulting in a shortened sleep time for the elderly.

4. Disease **.

As we get older, our physical condition deteriorates, and various diseases can affect our health.

At the same time, these diseases can also affect the sleep state of the elderly, resulting in shortened sleep time and other problems.

It is precisely because of the above problems that problems such as shortened sleep time of the elderly will occur. ......Therefore, for the elderly, they often only have five or six hours of sleep per day, and the specific manifestations are problems such as reduced deep sleep.

Therefore, for the elderly, measures should be taken to improve the problem of sleep deprivation. Specifically, on the one hand, it is necessary to exercise the body to strengthen the physical fitness, and on the other hand, it is necessary to soothe the body and mind and maintain a happy mood. This will allow you to sleep better.

In addition, the elderly have less sleep time at night and can take a nap during the day to compensate for the lack of sleep. In this way, the elderly can get enough rest, which is conducive to the physical health of the elderly.

Because their sleep quality is accumulated over the years, the sleep quality will get higher and higher, and they don't need too long to improve the quality of sleep, and then their brains are actually degrading with age, so they don't need so much sleep time to maintain the operation of the brain and the rest of the brain.

Many elderly people generally go to bed late at night, but they still wake up early. What is this for? Most people think that as people get older, their ability to sleep decreases, so the time and quality of sleep will gradually decline in the elderly.

So, what are the specific reasons for this?

1. Physiological factors.

1. Sleep is divided into two types: deep sleep and light sleep. One cycle decreases, and the other increases. As the elderly age, the deep sleep cycle of the elderly becomes less and less, resulting in more and more light sleep cycles, so they are easily awakened.

2. The elderly are more sensitive to environmental factors. It's easy to be woken up by some other sounds.

3. The living habits of the elderly are generally better than those of the young people now, and the biological clock wakes up earlier. Moreover, the body adjustment of the elderly is generally about an hour earlier than that of the young. So it usually gets up early.

2. Pathological factors.

1. Many elderly people suffer from certain diseases because of their reduced resistance and regulatory ability, and it is difficult to fall asleep when they go to bed at night.

2. Even if you fall asleep, the pain or discomfort of the body can easily bring the elderly out of sleep, resulting in a decrease in sleep quality.

3. Mental illness.

1. If the elderly suffer from insomnia, the quality of sleep will be very poor.

2. If the elderly are prone to dreaming when they sleep at night, it is easy to wake up in a dream, and it is more difficult to re-enter the society.

3. There may be some depression or anxiety in the spirit, resulting in poor sleep quality and easy to wake up early.

4. Long-term lying down will lead to a decrease in metabolic ability and blocked blood flow. It can cause pain in the body and is not conducive to sleep.

4. Respiratory diseases.

Most elderly people have loose throat muscles, and when they sleep, their tongue is easy to fall back, so the trachea will be blocked, resulting in poor ventilation. It will cause the elderly to wake up immediately after falling asleep, resulting in poor sleep quality and easy to get up early.

Sleep does have a lot to do with ageIn infants and young children, they need enough sleep, and it takes more than 9 hours to completely ensure the day's active energy. The middle-aged and elderly only need to maintain 7 hours of sleep to maintain the day's needs.

There are differences in sleep duration at different ages, why is there such a difference?

As we all know, human sleep gradually decreases with ontogeny and the passage of time. The sleep structure varies from deep sleep to light sleep, from babies born to teenagers, middle-aged and elderly people.

There is no universal standard for sleep, and it gradually develops with age. Like a newborn baby, in addition to eating, drinking, and Lazar are sleeping, sleeping more than 10 hours a day is to grow the body quickly. With the increase of age, the sleep time gradually decreases, the activity time gradually increases, and the sleep structure changes in old age, and only 7 hours of sleep is needed to meet the needs of the human body.

The only medical explanation is that the human body has fewer free recovery cells when they are young, and they need enough time to proliferate and grow, repair the necrotic cells in the body, meet the needs of the replacement of growth and development cells, and replenish fresh blood. Middle-aged and older people do not have this process, so the older you get, the less sleep you need.

Because the older they get, the aging of their tissues and organs and the deterioration of their functions, their immunity has been at a low level, and their ability to resist diseases has decreased; 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.

The short sleep time of the elderly has a lot to do with the speed of the body's metabolism. As we age, our body functions decline, our metabolism slows down, and we don't have as much time to rest, so we sleep less. Normal elderly people should sleep for 6-7 hours a day, which is normal, but if it is less than 6 hours, health will also be affected.

Sleeping too much can also increase the risk of Alzheimer's disease.

The older you get, the less sleep you get, which is caused by slower metabolism, deterioration of brain function, and the appearance of geriatric diseases.

1. Patients with short sleep time and body metabolism in the elderly are increasing in age, and their body functions are constantly weakening, their metabolism will slow down, and the rest time will also decrease, so the time to sleep every day will be less. In general, the elderly can sleep for 6-7 hours, but if it is less than 6 hours, the health of the elderly will also be affected, and too much sleep will also increase the risk of Alzheimer's disease.

2. When you get older, your body organs will also age, your brain function will decline, your brain cells will degenerate, and your brain's ability to coordinate day and night will decline, which will lead to sleep chaos, and the elderly will often have trouble sleeping.

3. Due to the deterioration of the body organs of the elderly, the body's immunity will also decline, and many diseases will appear in the body, such as high blood pressure, and these diseases will affect the sleep of the elderly.

It's not that the older you get, the shorter the sleep time you need, but the older you get, the secretion of melamine decreases, which makes it difficult to fall asleep, the quality of sleep decreases, you can't sleep, it's not that you don't want to sleep, now there are health products that can supplement melatonin! Help the elderly sleep peacefully!

What people tend to ignore is that the elderly often take a nap during the day or take a nap in the afternoon, and the total sleep time is not short. Therefore, in terms of the total amount of sleep throughout the day, the elderly do not sleep a lot, and the statement that "the older you get, the less sleep you need" is untenable.

In addition, during the survey, many elderly people who were in good health also reported that their sleep quality was not high, and they were always in a state of half-asleep and half-awake. To this end, CCTV financial reporters invited a young man and an elderly person as volunteers to conduct a comparative test. During the test, both volunteers slept with sleep monitors.

The test results showed that young people fell asleep quickly, had good sleep continuity, and had significant deep sleep, and had a wide range of EEG amplitude oscillations, while older people had the opposite effect, falling asleep slowly and EEG fluctuations were smaller. This suggests that older people have longer light sleep and shorter deep sleep.

A good sleeping environment can be created by comfortable bedding, protection from light and reduced noise disturbances. If the elderly have the habit of taking sleeping pills for a long time, then the incorrect way of using the drug will also affect their sleep, and the sleeping pills must be used in the hospital under the guidance of a professional doctor. We take regular walks during the day, engage in some physical activities, maintain a positive, optimistic and cheerful attitude, communicate more with other people, reduce the occurrence of depression and anxiety, which will also significantly increase our deep sleep time.

1.The brain is also immersed in the emotions of the day, and so on; 2. Physical factors. For example, it is not tired at all, physical sleeping habits, excessive tension, eating habits, etc.; 3. Environmental factors.

Such as noise, light, room temperature, bed, quilt, room, etc. 4. The combination of the first three factors. If the environment is not good, it affects the psychology, the environment is improved, and the psychology is strange.

As people age, their sleep time will also change, and as they get older, they will get shorter and shorter, which is regarded as an inevitable phenomenon and is considered to be not harmful to health.

In fact, this is a misconception that human health is closely related to the body's immunity, and an important factor in determining human health is the length of sleep, and sleep will also have an impact on brain health.

The older you get, the worse your physical fitness, the lack of the ability to sleep, if you get older, the better your sleep will be, you will live longer, otherwise it won't.

1. Physiological factors: As a person ages, the amount of time he needs to sleep also changes. Generally speaking, the older you get, the less time you sleep. And the younger you are, the longer you sleep and the more often.

Why do you need less sleep as you get older?

This is a natural phenomenon. In fact, the elderly, like the young, also need about eight hours of sleep a day.

And in addition to sleeping at night, many elderly people will also have a lunch break or afternoon break during the day, if you add these times together, in fact, the time is not short.

So why do the elderly feel that they feel less and less, because the elderly sleep has two characteristics, one is that the sleep time at night is short, and the other is that the sleep quality is not high, so many elderly people feel that their sleep time is constantly decreasing, which is related to psychological factors, and may also be the cause of the body, such as: melatonin secretion decreases, etc., these factors affect the quality of sleep, so many elderly people do not sleep well at night, and are easy to get sleepy during the day.

Take a walk regularly in your daily life, maintain a positive and optimistic attitude, reduce the occurrence of anxiety, help sleep, and also contribute to health and longevity.

Why do you need less sleep when you get older? 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 the needs of physical growth and growth, 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, older people with insomnia do not have difficulty falling asleep, but due to diseases and physiological changes, they wake up more frequently throughout the night and early in the morning. 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.

In conclusion, as we age, sleep also gradually decreases, which is due to several of the reasons mentioned above.
