Some people say that napping is a health care method, do you believe it? It is estimated that there will be many people shake their heads. Modern urban population life and work pace is increasing, especially some “office workers” about napping, I’m afraid it can only be a luxury, and the British and American countries people do not have the habit of napping, but also do not see people’s health is not good. So how about napping in the end? There has been a study found that 60 minutes of napping on the athletes’ responsiveness and body movement function recovery has a significant role. There are also scholars through the same group of college students found that the students after the nap on the cognitive performance of the graphic structure is significantly better than when there is no nap. U.S. scholars through the brain MRI results found that napping testers brain can automatically process and reorganize information, after the nap learning and memory test scores relatively high. China’s Yellow Emperor’s Classic of Internal Medicine also mentioned 11:00 to 1:00 p.m. proper napping is beneficial to the body to nourish Yin and Yang. Song dynasty statesman and literary scholar Wang Anshi also had made a poem: “fine book can hurt the old eyes, long woven grass comfortable drowsing. According to the woven grass and a rest, throw the book also young.” The meaning is tired of reading, leaning on the bamboo mat to take a nap, a snooze, there is the beauty of returning to old age. So it seems that napping on our health or have many benefits. So how should we nap? First, what time to sleep after lunch the human stomach has just been filled with food, a large amount of blood flow to the stomach, blood pressure drops, the brain oxygen and nutrition dropped significantly, immediately after the meal to sleep will cause insufficient blood supply to the brain, it is recommended that half an hour after the meal and then sleep. Second, how long to sleep the best 10 minutes or so nap “wakefulness” is the best, and after the nap 2 to 2.5 hours, the effect is still obvious. This “quick charge” nap helps to quickly improve alertness and restore body energy. After a nap, you can quickly get back to work and continue to complete important tasks. A particularly recommended time-control technique: grab a pen in your hand while napping and wake up as soon as it hits the floor. This process is usually 10 to 15 minutes. 20 to 30 minutes of napping is the worst, waking up feeling shaky “drunkenness” will last 30 minutes, then the “recovery effect” of the nap will be visible. 60 minutes of napping is not suitable for The 60-minute nap is not suitable for most workplaces, but it is the most beneficial for improving the brain’s cognitive memory. A new study published in the American Journal of the Neurobiology of Learning and Memory at the University of Notre Dame found that participants in the 60-minute nap group still scored better on cognitive tests taken a week later compared to participants in the 10-minute nap group. Napping for 90 minutes ensures a complete sleep cycle that includes both light and deep sleep (especially the dreaming stage), which is beneficial for improving creativity and enhancing emotional and procedural memory. For example, learning to ride a bicycle, play the piano, etc. After waking up more awake, there is no groggy feeling. Third, the sleep position is very important wrong sleep position on the one hand, easy to cause the body’s breathing obstruction. It is recommended to try to choose to lie down, so that all parts of the body to maximize the stretch, such as the office should try to lie on a chair or choose a comfortable side sleep position, bring your own pillow to reduce discomfort. Of course, nap is certainly beneficial, but not that everyone must nap, if there is no napping habits, and after the afternoon experience is still abundant, you do not have to join the ranks of nappers.
