For good quality sleep, it is important to start sleeping. To enhance immunity, September 1: 4:31

I think there are many people who say that it is difficult to fall asleep and that they cannot get tired because the severe heat continues.

Sleep is deeply related to the immunity that protects the body from the infection of viruses, etc. Experts say, "In order to get a deep and high quality sleep, it is important to especially value the time at the beginning of sleep."

I spoke to Seiji Nishino, director of the Sleep Biological Rhythm Institute in Stanford University, USA, who has been studying sleep for many years.



According to Nishino, the immunity that protects the body from external "invaders" such as viruses is closely related to sleep, and during sleep, autonomic nerve regulation and hormone secretion occur.



When sleep is disturbed, the balance of hormones and the like is lost, and the immunity is also reduced.



In order to get a good quality sleep, "how deeply you can sleep" is more important than "when you sleep", and you can get the deepest sleep within 90 minutes of starting to sleep.



During deep sleep, the brain can rest well and growth hormones are secreted.



Proper secretion of growth hormone helps to recover the fatigue of the brain and body, repairs cells while sleeping, and makes you feel "sleep well" when you wake up, as well as immunity and autonomy. It means that it also helps regulate nerves and helps maintain good health.



When Nishino's for good quality sleep is sleeping ", deep body temperature of the body is down.



The core body temperature is the minute that rose temporarily in such as exercise and bathing, there is a nature to be S'Agaro.



Sleep this order Taking a bath about 90 minutes before will lower the elevated core body temperature, which is effective for good quality sleep."



In addition, when you operate your smartphone before sleeping, the brain is stimulated and you feel as if you are in the daytime.



As a result, it can interfere with sleep, so caution is required.



Mr. Nishino said, "Increasing immunity also helps protect the body from viruses. In order to get a deep and high quality sleep, please start your sleep, especially the first 90 minutes." I will.
