What are the dangers of taking a half hour nap and taking a 2 hour nap?

Do not exceed half an hour, otherwise you will wake up dizzy and unconscious. If you don't have the conditions to rest in the place where you work during the day, you can choose to look at the scenery outside the window, or let your mind go and think freely for 5 10 minutes.

You can also move around, stretch your limbs, and stretch. Taking a break from heavy work for 20 minutes will save a lot of energy for the afternoon's work. For people who are overweight by 20%, napping will increase blood viscosity and easily cause blood vessel blockage;

People with low blood pressure and impaired blood circulation are not suitable for napping, because during sleep, the heart rate is relatively slow, the cerebral blood flow is reduced, and the cerebral blood supply is insufficient, causing autonomic dysfunction and causing other diseases. These people just don't overwork during the day, do a moderate amount of exercise, and ensure the quality of sleep at night.

True continuous sleep is at night, and napping is optional. If you are tired from work during the day, make up for it at noon, and make up for sleep will not have any effect on your sleep at night, but the nap time should not be too long.

Taking too long a nap can affect sleep at night, just as eating too much during the day will make you less hungry at night. Some people take a lunch break for two or three hours to sleep, and this is a problem. The normal lunch break should be half an hour to an hour.

The above content refers to People's Daily Online-It is best to control the nap time within half an hour What should I do with a high-quality lunch break?

You don't give me a lot of points, so I'll just score less, and I'll talk about it briefly.

It has been scientifically proven that people are divided into deep sleep and light sleep. I abstractly explain these two sleeps, people must sleep 8 10 hours at night, because of the biological clock, when you just fall asleep at night, it is light sleep, 22:00 2:

00.At this time, you have a lot of dreams, which belongs to the state of "half-asleep and half-awake", and sleeping is equal to sleeping in vain, so you get up at 2 o'clock to pee and still have fatigue. 2：

00 4:00 is a deep sleep, when consciousness is completely out of state, and the thief is most rampant at this time. Therefore, someone invented the ** sleep method, which is to only sleep deeply for 4 hours a day, but I think it is better to be a normal person.

Speaking of deep sleep, hypnotists can make you sleep deeply, and 15 minutes of sleep is equivalent to 3 hours of sleep. That's the magic of deep sleep.

I explained the above you should understand a little bit, and then go back to the original topic, short sleep at noon is because of the relationship between the biological clock, the quality of sleep is different in each time period, noon nap can enter deep sleep in a short time, sleep for half an hour to an hour, which is equivalent to sleeping for 6 or 8 hours, which can ensure the spirit of the day.

Because it is enough for people to take a ten minute nap at noon, that is, to rest and rest, the eyes to rest and rest, and the brain can be fine, so that there is a lot of energy for the afternoon work.

It should be said that a 10-minute nap at noon in winter is enough to restore our strength, but in summer we still need to sleep for about an hour.

It is best to keep the nap time at 10 to 20 minutes, you should have reached a state of meditation in this situation, and anyone who has meditated knows that as long as it is really quiet, it is more comfortable to sit for a few minutes than to sleep for several hours.

In practice, it varies from person to person, but a nap of 10 minutes to half an hour is generally the most suitable rest during work.

Of course, a reasonable nap is very beneficial, and of course, a bad nap is also harmful to health. Where there are two sides, isn't it?

Busy work and tense rhythm often make manpower inadequate, so napping has become an important guarantee for many people's work in a day. Experts believe that napping can not only enhance physical strength, eliminate fatigue, improve work efficiency in the afternoon, but also have the effect of enhancing the body's protective function. However, there are many things to pay attention to in napping, and only a reasonable napping method can achieve the best effect.

First, don't rush to take a nap after eating. Many people are accustomed to going to bed after lunch, and at this time, the stomach is just filled with food, a large amount of blood flows to the stomach, blood pressure drops, and the oxygen supply and nutrition to the brain drop significantly. Therefore, it is best to move for 10 minutes before napping to allow food to digest.

The second is to pay attention to the time to fall asleep. Most people think that as long as you sleep at noon, you can achieve the effect. However, according to experts, the easiest time for people to fall asleep is 8 hours after waking up in the morning or 8 hours before going to bed at night, around 1 o'clock in the afternoon.

Because at this time, people's alertness is in a natural decline period, and the body will get a good rest during the nap at this time.

The third is to pay attention to hygiene during naps. Don't eat anything too greasy before going to bed, and don't eat too much, because greasy will increase blood viscosity, aggravate coronary artery disease, and oversatiety will increase the burden of stomach digestion. In addition, after waking up, you can drink a glass of water to replenish blood volume, dilute blood viscosity, and then you can do some light activities such as walking.

Fourth, napping should not be too long. Experts believe that a healthy nap is most appropriate for 15-30 minutes, and the longest should not exceed 1 hour. If the time is too short to achieve the effect of rest; If it takes too long, you will wake up with a slight headache and general weakness, and it will not be easy to wake up.

Fifth, don't sleep on your stomach during a nap. It is understood that most people do not pay attention to the posture of napping, some lie on their stomachs, and some simply sleep on the table. In fact, sleeping at the desk will reduce the blood supply to the head, and people will wake up with a series of symptoms of cerebral ischemia and hypoxia, such as dizziness, dizziness, and fatigue.

At the same time, using your hands as pillows will compress your eyeballs, which will easily induce eye diseases over time, and lying on the table will compress your chest, affecting blood circulation and nerve conduction.

Taking a nap for an hour is a good habit because napping has a good effect and effect on the human body:

1. Napping can relieve stress, especially office workers, mental power, manual laborers, busy all morning, appropriate napping can make all organs of the human body completely relaxed, can effectively relieve pressure.

Second, high-quality napping can also consolidate people's memory, and through the complementarity with night sleep, it can also enhance people's creativity, improve the sharpness of thinking, and thus improve the quality of life and efficiency.

3. High-quality napping can promote cell renewal, silently regulate endocrine, make people's best and delay aging. During sleep, the human body can repair the body's immune function, recharge energy, and enhance the body's physique.

Fourth, in addition, napping can also be eye-catching. Relax your whole body during a nap, even if you don't have enough time to sleep well, take a nap, close your eyes and refresh your mind, so that your eyes are also in the most relaxed way, which can effectively prevent eye fatigue and effectively nourish your eyes.

If you insist on changing it, you have to re-establish the circadian clock rhythm and adapt it again, as long as your physique is good and you can adjust it.

That's a habit, I used to be like this, and now it's okay to go without sleeping at noon.
