This is the reason why we often do blankets when sleeping no matter how hot it is

It is a familiar item, but do you know for some reason that many people often put on blankets when they tell how hot the weather is?

Herding used to be a very expensive item in BC until the Middle Ages. But this day, the vast majority of us have at least one blanket for our own and the "body of separation" when we go to sleep.

But what is the reason why we form the habit of covering blankets, even when the weather is so hot?

According to Professor Alice Hoagland from the Sleep Disorders Prevention Center in Roschester, New York, the need for bed covers has two main reasons:

"The first reason is related to behavior, and the second is about physiology."

After 60-90 minutes of falling asleep, people show signs of hypothermia.

Compared to behavioral factors, physiological factor is a clear explanation for our behavior of quilting behavior.

About 60 - 90 minutes after falling asleep, people show signs of hypothermia. According to physiology, the higher the body temperature, the easier it is to wake up.

In contrast, when body temperature decreases, the body releases hormones melatonin - which helps to make it easier to sleep. Some doctors have tested when giving patients a special body temperature costume. They found that patients were more likely to sleep if their body temperature dropped by 0.5 to 1.5 degrees C.

But it is only in the early stages of sleep, after that time, the body will have more physiological changes.

When our sleep enters Rapid Eye Movement (REM), our body temperature is no longer regulated. At that time, the body is forced to rely on outdoor temperature.

And at night, the outdoor temperature will decrease, regardless of the weather. To prevent the body from getting cold, covering the blanket is an essential solution.

In addition, REM stage also causes the body to reduce hormone hormone serotonin - which regulates the mood of people.

A thick blanket can magically increase serotonin production.

However, many studies have shown that thick blanket can magically increase serotonin production.

In addition, Hoagland also shared that many people who have blankets when sleeping are formed from an early age . Due to the fear of having a cold when resistance is not fully developed, parents often have a habit of putting blankets on their babies when they sleep.

Over time, blankets become an integral part of when they go to sleep. And when they become habits, they will feel more sleepy if they have a warm blanket.

Now do not wonder why we should cover up when sleeping again! That's because you want to have a good night's sleep throughout the day.
