Bathing can also improve sleep
Professor Kobayashi, a professor at the Faculty of Engineering, Japan’s Ashikaga University of Technology, compared five healthy male college students between the ages of 20 and 25, comparing the situation of falling asleep after bathing with the situation of not sleeping directly without sleeping.
The test conditions are: bedtime is from 10:30 to 12:30, and wake-up time is from 7:00 to 8:00 the next morning.
The bathing time starts at 8 or 9:30 in the evening, and the temperature of the bathroom is set at 42 degrees Celsius, 40 degrees Celsius and 38 degrees Celsius.
The way to bathe is free to choose.
In order to accurately measure the temperature in the body, a special thermometer was inserted into the rectum of 5 people and monitored for 24 hours.
The brain waves of 5 people in sleep were analyzed.
Each person was observed for more than one month.
It was found that the bathing time did not bathe the index, and the time to go to sleep after going to bed was shortened by five people.
Moreover, the time is shortened to a large extent, and the time to sleep is extended to one-sixth.
It takes an hour and a half to go from bed to sleep without bathing. It takes only 20 to 30 minutes to get asleep after bathing.
There are also cases where a person who takes 30 minutes from going to bed without bathing can sleep in just 5 minutes after bathing.
The test results show that “the bath before going to bed can produce the result of entering deep sleep as soon as possible”.
The bathing ratio is 9:30 in the evening, and the effect is more obvious when bathing at 8:00 in the evening.
Regardless of the temperature of the bath water, once bathed, “the body temperature rises by zero.
5 seconds to 1 second”, which can lead to optimal sleep.
It seems that the process of releasing trace amounts in the body is closely related to falling asleep.
Professor Xiao Lin pointed out: “The general goal is to bathe in warm water for about 30 minutes.
This is good news for modern people who are upset by sleep.
