Everyone's sleeping habits are different. Some people like to sleep on their side, some like to sleep on their stomach, and others like to sleep under the quilt. Do you know that sleeping under a quilt is good for your health? Do you know how to recuperate when sleep is not good? Today Sihai Xiaobian will introduce you to the knowledge about sleeping.
Is sleeping with quilts healthy
Many women like to sleep with a quilt between them. They think it's more comfortable and safer to sleep in this way. In fact, there's a certain scientific reason for this kind of sleep management.
Wrong sleeping posture can not relieve fatigue, but can make people feel pain all over.
Sleep may wish to use a small pillow to ensure the correct position.
Sleep at night, people in supine legs are in a relaxed state, but in the connection between the waist and leg muscles due to day long time to maintain tension, will cause lumbar discomfort, especially the spine is not good people are more sensitive.
At this point, you can put a pillow under the knee to protect the spine joint.
When lying on the side, the spine is arched, and the pressure on it is relatively light. However, if the upper knee is pulled down, the front chest will be pressed to the side of the bed, which is not conducive to the health of the spine.
Therefore, when lying on the side, it's better to bend the legs slightly, and clip a small pillow between the legs to ensure that the spine and head are kept in a straight line, so that the muscles connecting the waist and legs can be fully relaxed, and the neck can be at a comfortable angle.
At the end of the speech, the relevant experts also specially remind you not to sleep in a prone position as far as possible. This position will be harmful to your health if it goes on for a long time.
Because prone, chest compression, easy to cause stiff neck, joint and ligament strain and increase the burden of heart and lung.
Suddenly shaking when sleeping
This is a normal phenomenon. Don't worry too much.
This is not a lack of calcium, the performance of calcium deficiency is cramps, limbs shaking, weakness, not convulsions when falling asleep.
To understand this problem, let's take a look at an example: many athletes shake their hands and feet to relax their muscles after doing strenuous exercise, especially anaerobic exercise (refers to weight lifting, dumbbell and other exercises that need to be suffocated).
Shaking the muscle is beneficial to release the lactic acid (a substance that makes people feel sore) accumulated in the muscle tissue after severe transportation.
Similarly, we need to know that sleep is not just a brain phenomenon, it is a physiological phenomenon that requires the whole body to participate.
During sleep, the nerves of human sensory organs, such as ears, nose and skin, are in a very dull state. Muscle tissue also needs sleep.
You can do a small experiment. When you wake up in the morning, squeeze your fist hard. Hehe, is it a little bit hard? )。
When you are sleeping, all aspects of your body are gradually relaxed, and muscles are no exception.
When the muscle relaxes to a certain extent, it will twitch by itself, just like an athlete shaking his hands and feet. Its function is to make the muscle reach the state of deep relaxation.
Therefore, this kind of limbs twitch when sleeping is very normal, in the case of daytime fatigue, it is more likely to happen at night.
How to recuperate bad sleep
Relax yourself properly
People's sleep is divided into two stages: physiological sleep and psychological sleep.
Physiological sleep refers to people's daily sleep time. If it reaches 3.5 hours, it can fully meet the needs of the human body.
Psychological sleep is a kind of satisfaction of people's subconscious to sleep.
So the more relaxed you are before going to bed, the better. Don't worry that you may only sleep three or four hours today. Worry that lack of sleep will affect your work the next day.
Don't worry too much about the amount of sleep
The amount of sleep requirements vary from person to person, and people of different ages are not the same. The younger the age is, the more sleep is needed. With the growth of age, sleep will gradually decrease.
A person does not have to sleep 8 or 7 hours a day. A reasonable amount of sleep should be able to relieve fatigue, maintain a happy spirit, and carry out a good day's work and study.
On the contrary, if you care too much about the amount of sleep, you will often feel uneasy because you sleep less than half an hour, which is harmful to a good sleep.
