Good sleep is essential for good health.Melatonin is a hormone secreted by glands in the brain, which plays an important role in adjusting the biological clock and the body's sleep cycle.Recently, researchers from Uppsala University in Sweden have published a study in the Journal of Sleep Research, showing that sleep under thick blankets can significantly increase the release of melatonin before going to bed, from from bed, from from, fromIt promotes better sleep.

Melatonin secretion often increases as it is dark and decreases as it is bright.Melatonin production decreases as we get older, this can cause sleep problems in some elderly people.However, it is still unclear whether the weight of the blanket will change the release of melatonin.

The researchers conducted a randomized research with 26 participants (15 men and 11 women) with an average ages of 24.4 years old.

Participants using blankets with weight (about 12% of body weight) and mild blankets (about 2.4% of body weight).For adults weighing 70kg, blankets weighing 8.4kg and light blankets are equivalent to 1.68kg.

During the experiment, the researchers analyzed the impact of different weight blankets on in saliva melatonin, cortisol levels, alpha-amylase activity (an indicator of the operating index of the magic system.Sutta), subjective feeling of sleepiness and sleep time of participants.

The results showed that within 1 hour before going to bed (22: 00-23: 00), the concentration of melatonin in saliva of participants using blankets weighing about 32%, while participantsUsing lightweight blankets without that change.

There is no significant difference between heavy blankets and mild blankets in cortisol levels in saliva, alpha-amylase activity, total sleep time and subjective sleep feeling before going to bed and the next morning.

The researchers believe that the pressure created by a thick blanket can activate the sensory organs on the skin, bringing the feeling of feeling through the spinal cord to the nucleus of the lonely sugar.The Solitarius nuclear area is the brain area containing small cell oxytocin cells, helping to promote the feeling of calm, happiness and reduce fear and stress.

Slone nuclei is also connected to the spare route and affects the release of melatonin.Therefore, thick, heavy blanket will eventually promote increased melatonin by activating the mind -direction to the feeling of the skin.

Using thick blankets can increase the amount of melatonin in saliva an hour before bed, this can help promote better sleep.However, it is still unclear whether this increase is significant in terms of therapeutic or the use of different weights whether or not the same weight will bring similar results.

Although this study shows that the weight can help increase the level of melatonin, each person may react differently with different weight blankets.Should choose the right weight of blankets based on comfort and personal needs.

In addition to using thick blankets, you can also combine other methods to improve sleep such as maintaining a regular sleep schedule and avoiding caffeine as well as blue light from electronic devices at night.

With the faster life rhythm of modern life, more and more people are facing sleep problems.This study gives the public a new perspective on how to improve sleep quality by adjusting the weight of the blanket.
