Is it better to take a nap or not?

Researchers in Germany believe that the sleep cycle is controlled by the brain, napping is a part of the natural sleep cycle, taking a nap can make people more awake, especially mental workers will experience that work efficiency will be greatly improved after lunch break. There are foreign data to prove that in some countries and regions with napping habits, the incidence of coronary heart disease is much lower than that in countries that do not nap, which is related to the fact that napping can soothe the cardiovascular system and reduce the tension of the human body.

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.

Frequent napping can increase the mortality rate of cardiovascular and cerebrovascular diseases and shorten the life expectancy. According to a study by Columbia University in the United States, napping causes cardiovascular pressure to drop rapidly, and rises rapidly after waking up, which is prone to cardiovascular and cerebrovascular lesions. In other words, napping causes you to alternate between exercise or work and sleep, and your heart rate and blood pressure fluctuate like a roller coaster, making it easy to go off track.

If you don't take a nap in the afternoon, there is no need for people who don't feel tired in the afternoon, so they don't have to sleep, so they will make themselves uncomfortable.

Not taking a nap is easy to cause various brain-dead behaviors in the afternoon.

First, for people over 65 years old or 20% overweight, napping will increase blood viscosity and easily cause blood vessel blockage;

The other type of person is a person with very low blood pressure, and the blood pressure will be relatively low during napping, and it will be more difficult to breathe;

The third type of people are people with serious disorders in the circulatory system, especially those who are often dizzy due to narrowing of the cerebral blood vessels, because the blood from the brain will flow to the stomach after lunch, the blood pressure will decrease, and the oxygen supply to the brain will be reduced.

In addition, people with insomnia problems should also avoid napping during the day. If you can't sleep for a while at noon, then do other relaxing things, such as listening, etc., so that you can maintain a good state of relaxation and better meet the work and study in the afternoon.

For some elderly people, one more nap will increase the possibility of a cardiovascular and cerebrovascular disease attack, especially those with underlying cardiovascular diseases, if you do not pay attention to these small details in life, it may cause irreversible consequences.

According to the study, people over the age of 64 who weigh more than 20% of the standard body weight, people with low blood pressure, people with serious disorders of blood circulation, especially people who often experience dizziness and dizziness due to narrowing of cerebral blood vessels. This is because during sleep, the heart rate is relatively slow and the cerebral blood flow is reduced, which makes it easy for them to have a temporary lack of blood supply to the brain, causing autonomic nerve dysfunction and other diseases. As long as these people pay attention not to overwork during the day (especially in the morning), do some physical exercise in moderation, have a regular life, and go to bed on time at night to ensure the quality of sleep.

No nap is required.

I would like to make three points:

1. Lunch break is very important, but not everyone needs it. At noon, the yang energy rises, and people have eaten lunch in a busy morning, and they are easy to get sleepy, so it is best to take a rest; If you don't think it's necessary, and your spirit in the afternoon is not affected, you can skip sleeping.

2. The best time to take a lunch break. Doing the right thing at the right time is the best time to be efficient, and the best lunch break is around one o'clock, ten minutes after eating. And the nap time should not be too long, not more than 1 hour, otherwise it is likely to have a headache;

3. Where to take a nap. It is best not to lie on the table during the nap, it is harmful to the eyes and arms, and it is better not to sleep if you sleep.

ps: Sitting down or taking a nap just after eating will indeed increase the fat in the lower abdomen, and it is not good for the stomach, so it is best to take a walk for ten minutes after a meal to read a book or take a lunch break, which is more scientific.

Napping is a good habit, but don't sleep too long, generally 30-60 minutes is best! It is good for study and work in the afternoon, there is no direct connection between the belly and the nap, if you want to be in good shape, you must exercise more and pay attention to your diet!

A lunch break is necessary. If you don't take a lunch break, there is no quality at all in the afternoon class.

I guess, your question shouldn't be about taking a lunch break, it's about how to reduce belly...

Sit-ups are useful!

Because of this habit, once you develop it, you will never be able to quit it again.

Get up in the morning and get some exercise!

Is it OK to take a nap for too long?
