Is it good for your health to sleep naked?In the Japanese environment, I recommend wearing pajamas "Pajamas from nakedness" is good for Japanese sleep

In order to increase the difference between the day and night of deep body temperature, we recommend that you spend regularly rather than sleep naked.If you can't sleep well, your body temperature will not rise even at the peak in the evening, the body temperature will not fall down even in the evening at night, and the rhythm of the deep body temperature is disturbed.Hormones called "melatonin" affect the rhythm of deep body temperature.Melatonin is secreted a lot during sleep, and when waking up in the morning and exposed to the sun, the secretion stops with the command from the brain.However, many modern business people are late home, and they tend to be disturbed with natural light because they are exposed to artificial light (blue light) by looking at smartphones and PCs just before going to bed.Review your lifestyle and improve your sleep quality.

■ It is good to do aerobic exercise such as walking and stretching

Another thing I would recommend is moderate exercise.Many of the business people centered on desk work may feel chronic lack of exercise.In such a case, it is a good idea to do aerobic exercise such as light walking or stretching 2-3 hours before going to bed.If you temporarily raise your body temperature in this way, your body temperature will decrease by the time you enter the futon, and you will naturally sleep.However, if you exercise too much, your brain will get excited and you will not be able to sleep, so avoid exercising until you become a kuttakuta.

Also, there is no comparative data, but when you sleep, it is better to wear a sleepwear, not naked.Because this is a hot and humid Japan.We are sweating about one plastic bottle during sleep and in winter.If you sleep naked in such an environment, your sweat will remain on the surface of the body, and the discomfort caused by stuffiness will turn over.Frequent turns can hinder sleep.What I recommend for sleeping is "pajamas", which has a good touch and has excellent moisture absorption and has a certain amount of trunk.Pajamas are easier to maintain high quality sleep because they absorb and vaporize sweat to lower body temperature.

In addition, the habit behavior that you do before going to bed every night, such as listening to music or reading a book, is also called a "sleep ceremony", but changing into a sleepwear is also true.The consciousness of "doing what to do before going to bed" is transmitted to the brain and body as a signal of "I'm going to sleep", and it naturally switches to a sleep switch.
