More nap in the afternoon, scientific nap can live longer
The fierce competition in society and the accelerated pace of life will inevitably lead many people to work hard and have no time to take care of lunch breaks.
In fact, after a morning of work and study, the human body consumes too much energy. After a nap after lunch, it can effectively compensate the human brain, and the physical exertion is a substitute for health.
銆€銆€From a physiological point of view, the excitement of human brain cells can generally last for 4?
After 5 hours, it will be transferred to the suppression state.
Especially after lunch, the blood supply to the digestive tract is significantly increased, and the blood supply to the brain is significantly reduced, which leads to a corresponding decrease in oxygen and nutrients that enter the brain with blood flow. Therefore, the body’s biological clock has a sleep rhythm, which makes people feel uncomfortable., a feeling of drowsiness.
At this point, the body needs to be adjusted for a short period of time to eliminate fatigue, restore physical strength, and stabilize the balance of nervous system function.
銆€銆€鈥淣apping鈥?is the most recommended 鈥渉ealthy living habit鈥?by experts. It not only can significantly improve immunity, but also quickly relieves nausea and makes mood and energy better.
銆€銆€The Spanish store will be closed every 2:30 pm until 5 pm in the evening.
It turned out that the Spaniards participated in the “National Nap Sports”, and it was fixed for two and a half hours every day for everyone to take a nap.
銆€銆€In the United States, 鈥渓earning for a nap鈥?has become the latest fashion. Many companies have stipulated that employees should be encouraged to take a nap at noon and gradually work hard to cope with more work in the afternoon.
銆€銆€3 big benefits in the afternoon, 1, higher immunity, immunologists say that after lunch, to help digestion, the body will automatically be caused by parasympathetic nerves. At this time, a short sleep can stimulate lymphocytes in the body and enhance immune cells.Active.
Cardiac over-force Spanish medical research shows that 30 minutes a day nap, the hormone secretion in the body is more balanced, and the incidence of cardiovascular diseases can be reduced by 30%.
銆€銆€3, the mood is more comfortable American Harvard University psychologist wrote a report, published in the latest “Natural Neuroscience” journal, the content shows that afternoon snoring can improve mood, reduce body tension, relieve stress – the effect is like sleepingAll night (8 hours).
銆€銆€So how do you take a nap scientifically?
銆€銆€First of all, the nap time should not be too long, preferably within 1 hour.
銆€銆€Physiological studies have shown that human sleep is divided into two stages: shallow sleep and deep sleep.
Usually, people are sleeping 80?
After 100 minutes, it gradually changed from light sleep to deep sleep.
During deep sleep, the inhibition process of the brain’s central nervous system is obviously strengthened. Many capillary networks in the brain tissue are temporarily closed, the cerebral blood flow is reduced, and the body’s metabolism level is significantly reduced.
If people suddenly wake up during deep sleep, because the deep inhibition process in the cerebral cortex cannot be immediately relieved, the closed capillary network can not be opened immediately, which will inevitably lead to transient blood supply to the brain and transient autonomic nervous system function.The tension will make the body feel very uncomfortable.
This discomfort will last for about 30 minutes and will gradually disappear.
It can be seen that the nap time is not as long as possible, but should be within 1 hour, which can effectively eliminate fatigue, and not sleep too much and not wake up easily.
銆€銆€First of all, it is not advisable to take a nap immediately after a meal.
銆€銆€Do not sit down or lie down after a meal, stand for 30 minutes, wash the dishes, place flowers and the like.
Then go downstairs for 30 minutes to help digestion.
Then you can sleep, it is best to sleep for only 30 minutes, many friends said that it is very painful at the end of the nap.
But I still want to sleep after I have finished sleeping. I have a headache and a headache. This is because you have slept for too long and your head is deprived of oxygen.
Because the stomach is full of undigested food after lunch, and then immediately flipped over and turned to cause a feeling of fullness.
The correct way is to do some light activities after lunch, such as walking, belly, etc., and then take a nap, which is conducive to the digestion and absorption of food.
銆€銆€Third, pay attention to sleep posture.
銆€銆€It is often seen that someone is sitting on a chair or a sofa while napping, and some people simply sleep on the table.
In fact, these practices are not scientific.
When the human body is in sleep state, the muscles relax, the heart rate slows down, the blood vessels dilate, the blood pressure decreases, and the blood flowing into the brain is relatively reduced.
Especially after lunch, the breakthrough blood enters the body. If you sit back and sleep again, the brain will be deprived of oxygen for a long time, causing people to feel heavy, weak, soft legs and other discomfort.
While sleeping on the table, it will press up and down, block breathing, and increase the burden on the heart and lungs.
It is generally believed that the sleeping position is better in the right lateral position, because this can reduce the burden on the heart and increase the blood flow of the liver, which is conducive to digestion and metabolism of food.
But in fact, because of the nap time correction, you don’t have to be forced to sleep on the left, right, and supine, as long as you can fall asleep quickly.
