in one's life, one-third of people sleep, and one-third of them sleep every day. Many people also form the habit of taking a nap at noon. Let's take a look at the benefits of taking a nap at noon.
What are the benefits of a midday nap? 1. Repair brain nerves, improve strain and memory
Researchers at the University of Wisconsin found that sleep can promote the repair of brain cells. In addition, in 2014, a study on the website of the American Public Library of Science showed that sleep at night and during the day can also strengthen memory. Napping also has the function of resting and recovering the brain, improving people's memory and helping people remember complex concepts. A 2008 study by Sarah middlenick and colleagues at the University of California showed that daytime naps generally improve memory, while caffeine consumption does not help, or even worse, memory.
2. Promote lacrimal secretion, effectively 'nourish' eyes
When you close your eyes and go to sleep, the ciliary muscles of your eyes can rest after a long morning's hard work, effectively preventing the decline of your vision. Not only that, the lacrimal gland in the inhibition state in the daytime also began to secrete a large number of tears, moistening the eyeball which was dry due to long-term working condition; the temperature of the cornea increased, and the cell metabolism accelerated. Shi Ming reminded that if you can't guarantee a nap every day, you can also play a role by closing your eyes a little.
3. Repair the body's immune function and strengthen the body
Professor berry middot Darby, an immunologist at the University of Florida, led the research team to conduct a series of studies on the relationship between sleep, hypnosis and human immunity. The results showed that the levels of T-lymphocytes and B-lymphocytes in the blood of the subjects were significantly increased after hypnotherapy. The immune system can be patched up to some extent during sleep and in turn regulate sleep. Sleep experts at the German Institute of psychiatry found that 1:00 noon is a clear peak of sleep during the day. At this time, a short sleep can effectively stimulate the body's lymphocytes and enhance the activity of immune cells.
4. Promote cell renewal and repair skin
The metabolism of skin is the most vigorous in sleep. Because when you fall asleep, the consumption of muscles, internal organs, etc. is reduced, skin blood vessels are completely open, blood can reach the skin fully, provide nutrition for it, carry out self-healing and cell renewal. That's one of the reasons why the whole person looks refreshed after a good quality nap, Shi said.
5. Repair oxidative damage, delay aging
Another possible function of sleep is antioxidation, which provides repair of oxidative damage to the body, according to an article published on the US' nature 'website. Experiments have proved that animals deprived of sleep will show more obvious oxidative damage. This may be because during sleep, many proteins begin to synthesize, including some needed for antioxidation. Siesta is helpful to supplement the lack of sleep at night and play a certain role in promoting repair.
