How important is sleep for our physical health? There was once a study that told us the answer.
People who slept less than 5 hours a day had a 27 percent risk of developing arteriosclerosis.
People who sleep 7 hours a day have a 6% risk of developing arteriosclerosis.
Two hours of sleep time, why is the gap so large?
This is caused by blood pressure.
When people fall asleep, their blood pressure will also decrease. However, people who sleep less for a long time have high blood pressure.
Moreover, the pressure is large, the cortisol secretion is strong, and it will further raise blood pressure. In the long run, how can it not be easy to get cardiovascular and cerebrovascular diseases?
Since sleep health is so important, is it better to sleep more?
There used to be an old saying that "a person sleeps three times, and his life is thinner than paper." After modern scientific research, the four kinds of sleep really can't sleep, otherwise it may be life-threatening!
01 Sleep under a quilt
As the saying goes, "sleep under a quilt", in fact, it is really not safe. Many people like this way of sleeping, which can easily lead to some health problems.
Sleeping under a quilt, the human body can inhale much less oxygen. The quilt will contain a lot of carbon dioxide that cannot be discharged. As a result, chest tightness, shortness of breath, dizziness and other situations are very easy to occur.
Moreover, if you sleep with your head covered by a quilt, the environment is too humid and not ventilated, and it is more likely to cause a cold.
02 Sleep upside down day and night
In daily life, many people will fall asleep day and night because of various factors such as personal living habits and work arrangements.
If we sleep in this way, "sleep replenishment" will not make up for the health we owe to the body.
Once the university of Surrey research team has done research on the method of sleeping day and night upside down. They found that if a person stayed asleep for three days and nights, the body's gene expression would be disordered!
Over time, the risk of genetic mutations skyrockets. The body's metabolic capacity declines, and various small problems appear.
03 Go to sleep after eating
There are also many people who like to fall asleep immediately after eating a full meal. If you talk about him, he still feels wronged. It is a physiological phenomenon that when you are full, you will fall asleep.
When you have just eaten a full meal, most of the blood in your body will be concentrated in the gastrointestinal tract. At this time, it is indeed normal for people to be sleepy. But don't sleep!
Sleeping after eating, gastrointestinal peristalsis becomes slower, which not only affects digestion and metabolism of food, but also may cause other diseases, such as gastroesophageal reflux disease.
Because the stomach is regurgitated, it will also be close to the throat, trachea, lungs and other tissues, so many people who eat and sleep will not only have heartburn and pantothenic acid, but also cough, throat ulcer, asthma and so on.
04 Fall asleep after getting drunk
After people get drunk, immediately falling asleep on their heads is also an extremely dangerous move.
People who are in a drunken state have a full stomach for the most part. If you vomit later, if you sleep on your back, you can choke on your own vomit.
That's why after getting drunk, someone has to look after it. Or you can't sleep upside down and spit out what's in your stomach to lie flat.
Otherwise, vomit enters the respiratory tract and the person may be life-threatening.
Dr.X said
When I was a child, I didn't understand the importance of "eating well and sleeping well". Now I understand that eating well and sleeping well can prove to a certain extent that the body is relatively healthy. However, 4 types of sleep can not sleep. The more you sleep, the more you hurt your body!
