Due to the high concentration and tension of physical and mental power, new fatigue is generated, and the calories in the human body are also greatly consumed, at this time, physiological functions in addition to compensating for the calories consumed, but also require to be able to properly eliminate fatigue, restore energy, and have a relatively good mental state in the afternoon to cope with work.

2. Replenish sleep, relieve heat and relieve fever.

In summer, the days are long and the nights are short, the weather is hot, the birds and cicadas are noisy in the morning, the mosquitoes and flies crawl at night, and the heat hits people, falling asleep late at night, waking up early in the morning, not only the sleep time is short, but also the sleep quality is not high, which requires more napping to supplement the lack of sleep at night.

3. Enhance physical strength and improve function.

Napping is not only conducive to making up for the necessary sleep time, so that the body can get full rest, but also has a good effect on improving the function of the brain blood supply system, enhancing physical strength, eliminating fatigue, and improving the work efficiency in the afternoon. In addition, napping can also reduce the chance of cerebrovascular accidents.

4. Protect the brain and relieve tension.

During sleep, not only the nerve cells of the cerebral cortex are protected and inhibited, and they are rested, but all parts of the body also get a comprehensive rest, the muscles of the whole body are relaxed, the physical strength consumed by the activity can gradually recover, and the various organs inside the body can work calmly and regularly.

Studies have confirmed that napping relaxes and rests all systems of the brain and body, and is more effective than drinking coffee and cola in helping people relax their minds, reduce stress, and eliminate fatigue. And this relaxation is becoming more and more important for modern people. A 30-minute nap a day can reduce the incidence of coronary heart disease by 30%.

But it's best not to take a nap.

However, in order to achieve a healthy nap, there are also a few points to pay attention to: it is not advisable to overeat before napping, and start taking a nap half an hour after meals, and the time should be within half an hour. If possible, it is best to lie down for a nap, but most office workers take a nap due to limited conditions, which will reduce the blood supply to the head, and a series of symptoms such as dizziness, dizziness, and fatigue will occur after waking up, and will also compress the eyeballs and induce eye diseases.

In addition, napping at the desk can compress the chest, affect breathing, and also affect blood circulation and nerve conduction, making the arms and hands numb and painful.

Take a nap to work harder.

Napping is good for the body's circulatory system.

Napping is a powerful way to help people concentrate and can also be used for beauty.

Take a nap after eating at noon, preferably for 30-40 minutes.

It can restore physical strength and will not gain weight easily.

This will affect the blood supply to the head, and it is easy to experience dizziness and dizziness after waking up. In the long run, a person's memory will fade or they may develop cerebral ischemia.

Avoid taking a nap immediately after lunch, people's gastrointestinal peristalsis is strengthened, blood circulation is accelerated, and falling asleep at this time will cause insufficient blood supply to the whole body and brain, and after waking up, it will be more tired and uncomfortable.

Do not wake up violently after waking up after a nap after waking up the heartbeat slows down, the blood supply to the body is small, the heart and cerebral blood vessels are relatively constricted, if you wake up, it will inevitably make the heart and cerebral blood vessels expand rapidly, which is easy to cause cerebral hemorrhage.

But napping is good for most people, and even a 30-minute nap may help you get rid of fatigue. However, there are some people who are exceptions. The German psychiatrist Schulley, through a large number of studies, believes that at least the following types of people are not suitable for napping:

1 Persons over the age of 64 who weigh more than 20 of the standard weight; 2 People with low blood pressure; 3 People with severe disorders of the blood circulation system, especially those who often experience headache and dizziness due to narrowing of cerebral blood vessels. Because when people are sleeping, the heart rate is relatively slow, the cerebral blood flow is small, the above kinds of people, in the afternoon nap is prone to temporary insufficiency of the brain, resulting in autonomic nerve dysfunction, so that when you wake up from a nap, there will often be dizziness, headache, fatigue and other phenomena, making people feel uncomfortable and uncomfortable. In particular, if the nap time is too long, the central nervous system of the brain will deepen the inhibition, prompting the blood vessels of brain cells to close for too long, so that the blood flow to the brain will be further reduced, and the symptoms will be more obvious after the nap, and even aggravate the condition.

Therefore, it is best for the above patients not to take a nap. Pay attention to work in the morning and do not overly fatigue, and ensure the quality of sleep in the evening, which can reduce physical fatigue and other discomforts.

Maintaining your beauty can relax your body and mind.
