What are the dangers of sleeping too little?

Sleep deprivation varies from person to person and requires different amounts of time. Some people get enough sleep by sleeping 4 hours or even 2 hours a night. Generally speaking, the sleep duration in infancy is relatively long, generally about 10 hours, and in childhood it is 8-10 hours.

Entering adulthood, most people generally take 6-8 hours. Older people may sleep for a shorter period of 6 hours. If it is lower than most people's sleep time, it is called sleep deprivation, so it is a relative concept, everyone is different, and each age stage is different.

The harm of lack of sleep is first of all to affect the quality of life, lack of sleep can easily cause dizziness, memory loss, unsteady walking, decreased work efficiency, etc., and even cause high-risk workers, such as taxi drivers, doctors in the medical industry, operating departments, surgeons lack of sleep, easy to lead to occupational risks. There is also long-term lack of sleep, which can easily lead to neurasthenia, anxiety or depression, and even mental abnormalities.

There are many harms of sleep deprivation, mainly including susceptibility to disease, neurasthenia, and organ damage, as follows:

1. Prone to illness: lack of sleep may cause low immunity, easy to catch colds, and cause pain and discomfort all over the body;

2. Neurasthenia: Lack of rest for a long time, brain cells can not get effective rest and sufficient oxygen supply, causing nerve excitability damage in the cerebral cortex, resulting in neurasthenia, easy forgetfulness and even dementia;

3. Organ damage: long-term lack of sleep, cardiovascular and cerebrovascular can not get effective rest, resulting in cardiovascular disease.

Regular sleep deprivation can cause many physical and mental harms, such as decreased thinking ability, weakened alertness and judgment, and immune dysfunction.

If a person only sleeps 6 hours a day, according to scientific research, the most important thing is to ensure the quality of sleep at the beginning, because as long as you ensure that you will not be disturbed by the outside world at the beginning of sleep, then the impact of less sleep time can be minimized. In the book "Stanford Efficient Sleep Method", the concept of "**90 minutes" is proposed, and the most critical thing for high-quality sleep is 90 minutes at the beginning of sleep.

As long as no one is disturbed for the first 90 minutes, even if we only sleep 6 hours a day, we will get a good night's sleep. But if we are disturbed by the outside world, or if we can't sleep because of our own situation, then no matter how long we sleep, we won't have any energy the next day.

In order to improve the quality of sleep, you can go to bed at 12 o'clock at night and wake up at 6 o'clock in the morning. You can take a short lunch break at noon, why do you choose such a rest schedule? Because everyone is busy with work now, and many people have a lot of workload, which causes a situation of poor sleep quality.

In order to avoid this from happening, it is best to improve the quality of sleep at night as the main premise.

Let's talk about how to spend the day efficiently. In the morning, you can set two alarms, and points, the first alarm should be gentle; When you wake up to the alarm, open the curtains and wash your hands with cold water; Have breakfast and start your day. In the evening, after dinner, start soaking your feet, finish after 10 minutes, and then have fun or read a book for a while until you start to fall asleep.

Go to bed early and get up early is in good health, the plan of the day lies in the morning, I believe that with a good work and rest habits, the day will be a hundred times more energetic.

With the continuous acceleration of the pace of modern society, more and more people have the problem of sleep deprivation in their lives. For many people, staying up late has become the norm, but does one or two hours of sleep each day also count as staying up late? This article will delve into this question from a scientific point of view.

First of all, we need to understand the importance of sleep for the human body. Sleep is one of the most important physiological needs of the human body, and it is also one of the most basic repair and recovery mechanisms of the human body. During sleep, various physiological functions of the human body will enter a state of rest, so that the body can be fully rested and repaired.

Moreover, getting enough sleep can also promote the body's internal metabolism and the function of the immune system, thus maintaining the health of the body.

However, if you don't get enough sleep every day, it will cause great harm to your body. Studies have shown that sleep deprivation can lead to a decline in physical performance, making the body prone to fatigue and sleepiness. Long-term lack of sleep can also lead to decreased immunity, susceptibility to diseases, and damage to cardiovascular and cerebrovascular organs.

At the same time, lack of sleep can also have a negative impact on the physical mood and psychology, making people prone to negative emotions such as irritability, depression and anxiety.

So, does one or two hours of less sleep a day count as staying up late? According to the World Health Organization, adults should get 7-8 hours of sleep a day. If you sleep less than 7 hours a day, you can be considered sleep deprived.

And if you sleep less than 6 hours a day, it can be considered a severe sleep deprivation. Therefore, one or two hours of sleep per day can indeed be considered a state of sleep deprivation, and severe sleep deprivation is even more harmful to the body.

So, why are modern people prone to sleep deprivation? On the one hand, the pace of life in modern society is faster than ever, and many people have to shorten their sleep time for the needs of work and life. On the other hand, many people rely too much on electronic devices such as mobile phones, TVs, and computers, resulting in a late time to go to bed at night and make it difficult to ensure adequate sleep time.

In addition, some bad lifestyle habits, such as excessive alcohol consumption, smoking, and unhealthy diet, can also affect the quality of one's sleep.

In response to the problem of lack of sleep, we should take positive and effective measures. First of all, we need to pay more attention to sleep and ensure that we sleep no less than 7 hours a day. Secondly, we should reduce the amount of time we spend using electronic devices as much as possible, especially at night close to bedtime.

At the same time, establishing good lifestyle habits, such as regular diet, proper exercise, and avoiding excessive fatigue, can also help improve sleep quality and maintain a healthy physical state.

In conclusion, one or two hours of sleep less per day can indeed be considered a state of sleep deprivation, and sleep deprivation can have a negative impact on a person's body and mind. Therefore, we should take active measures to ensure adequate sleep time and maintain a good living state to maintain a healthy and happy life.

Sleep is our normal physiological activity, our body gets enough rest when sleeping, and each organ operates, its own role. Let us be able to work energetically the next day, too little sleep every day will cause a great burden on the body, affecting the normal work of various organs of the body.

Normal people should sleep for about seven hours a day, if they have their own good sleep quality, with an adapted rest and rest schedule, they can adjust to about six hours a day, but four hours is really too little, and the body can not get effective rest. We should ensure that the sleep time is two to three hours a day to make our work, study and life not affected, four hours to the eye tracking cycle, to the light sleep time, the deep sleep time is very short, about two sleep cycles, so that the body can not get effective rest will lead to a decline in immunity. The working condition deteriorates.

So we're going to take proper breaks. No matter how busy young people are with their studies, they must ensure normal rest, at least no less than six hours, because the sleep time is too short, the body can not get effective rest, our work, study and life will be very inefficient, and we feel that our brains are chaotic and cannot concentrate on anything?
