Six benefits of taking a nap
1. Reduce blood pressure
A recent study by researchers at Allegheny College in the United States found that if people's blood pressure rises due to work stress, they might as well take a nap, which will help lower their blood pressure.
Protect the heart
A study in Greece shows that taking a 30-minute nap at least three times a week can reduce the risk of sudden cardiac death by 37%; Another data proves that the incidence of coronary heart disease in countries and regions with lunch break habits is much lower than that in countries that do not take a nap. Researchers believe that this may be because lunch break can relieve the cardiovascular system and reduce the tension of the human body.
Enhance memory
American researchers have found that taking a nap can greatly improve people's energy and alertness; Research from the University of Dü sseldorf in Germany shows that taking a nap can not only eliminate fatigue, but also enhance memory.
4. Improve immunity
Sleep experts at the German Institute of Psychiatry found that noon 1 is the obvious sleep peak during the day. A short sleep at this time can effectively stimulate lymphocytes in the body and enhance the activity of immune cells.
Step 5 cheer up and drive away depression
Psychologists at Harvard University have found that taking a nap in the afternoon can improve mood, reduce tension and relieve stress. A study by Stanford University School of Medicine found that taking a nap every day can also effectively drive away depression.
6. Eliminate fatigue and restore energy
In the morning, people are more energetic, because after a night's rest, people's internal functions have been rested, and the fatigue of the previous day has disappeared. However, after a morning's work or study, due to the high concentration and tension of physical and mental strength, new fatigue appears, and the heat in the human body is also consumed in large quantities. At this time, the physiological function not only needs to compensate the consumed calories, but also needs to properly eliminate fatigue, restore energy, and cope with the afternoon work with a relatively good mental state.
Matters needing attention in summer nap
1. Don't go to bed immediately after lunch.
Taking a nap after a meal may cause food reflux, make gastric juice stimulate the esophagus, make people feel uncomfortable, and may cause reflux esophagitis in severe cases. So it's best to rest for about 20 minutes before going to bed after lunch.
2. The nap time should not be too long.
Our nap time must not be too long, but it should not be too short. Generally speaking, ten minutes' sleep is enough. If you are used to sleeping for a long time, it is best not to exceed forty minutes. Because after we sleep much, people will fall into a deep sleep state at 1, and then our central nervous system will be deeply inhibited, thus gradually slowing down the metabolic process in the body and waking up more sleepy.
You'd better go to bed and take a nap.
The ideal siesta is supine, which can ensure more blood to flow to digestive organs and brain, and supply enough oxygen and nutrients, which is conducive to the recovery of brain function and help digestion and absorption. Many people are used to sitting on the table or taking a nap on the table, which will oppress the body, affect blood circulation and nerve conduction, and can't make the body adjust and rest, which will seriously lead to cervical spondylosis and lumbar disc herniation.
