Many people have this feeling that after lunch every day, people begin to feel sleepy. If you don't sleep for a while at noon, you will feel weak all afternoon. That's true. More and more studies have found that a nap is really needed by the human body.
Sleep at noon and take a nap at noon.
Under normal circumstances, the two most sleepy hours in a day are 1:00~4:00 in the morning and 13:00~ 16:00 in the afternoon. In the way of keeping in good health, sleeping "meridian sleep" is called the magic weapon of keeping in good health. Meridian sleep means falling asleep on time at noon and noon every day. Its main principle is "sleep at noon and take a nap at noon".
Viscount means that you must get ready for sleep around 22:00 at night, and it is best to fall asleep before midnight (23: 00). The sleep efficiency during this period far exceeds other periods.
◆ Taking a nap means taking a rest for 20 ~ 30 minutes at noon (1 1 ~ 13). Even if you can't sleep at noon, close your eyes.
During these two periods, controlled by the biological clock, the human body needs sleep to ensure physical strength and spirit again.
Short time and high efficiency.
1. Eliminate fatigue and restore energy
After a morning's activities, the human body consumes a lot of heat. At this time, physiological function requires not only to supplement calories, but also to properly eliminate fatigue, restore energy, and have a relatively good mental state in the afternoon. Therefore, even if you only sleep for 10 minutes at noon, the effect of eliminating fatigue is much better than sleeping for two hours at night.
2. Regulate emotions and relieve stress
Taking a nap in the afternoon can improve mood and reduce tension. Psychologists at Harvard University have found that taking a nap can improve mood and relieve stress. Taking a nap every day can also effectively drive away depression.
3. Improve body immunity
People with low immunity tend to feel tired every day and need to take a nap during the day to restore their physical strength. Sleep experts at the German Institute of Psychiatry found that noon 1 is the obvious sleep peak during the day. At this time, lunch break can effectively stimulate lymphocytes in the body and enhance the activity of immune cells.
Protect your 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%; In addition, taking a nap for 30 minutes every day will make the hormone secretion in the human body more balanced and reduce the incidence of cardiovascular diseases by 30%.
How to have a high quality lunch break?
1. It should not be too long.
The nap time should not be too long, 10-30 minutes is appropriate.
2.20 minutes lunch break
Find a quiet place, close your eyes and rest for 20 minutes, whether you can fall asleep or not. Otherwise, if you sleep too long, you will wake up dizzy and unconscious.
Pay attention to your lunch break posture
Although the lunch break is short, don't sit on the table or lie prone to sleep, which will affect the blood supply to the head and make people feel dizzy and weak after waking up. During lunch break, you can put on your neck pillow and lean back on the chair, and put your feet on the lower table for a while.
