Sleeping with your belly covered is a habit in the DNA of Guangdong people

Cover your stomach when you sleep or you will catch a cold! This is a familiar saying that every mother nags her children countless times before going to bed. So is there any scientific basis for covering your stomach when you sleep?

Essentially, the belly button is a scar. During the embryonic stage, the fetus relies on the umbilical cord to connect to the mother to obtain oxygen and nutrients to maintain life. After birth, the doctor will cut the umbilical cord, and when the umbilical cord stump falls off, the belly button appears.

The navel is the last closure point of the abdominal wall during embryonic development. It is the thinnest part of the abdominal wall, has the weakest barrier function, and has no muscle and fat tissue protection under the skin. Therefore, it is particularly sensitive to external stimuli and is a relatively weak part of the human body, which needs to be protected. Traditional medicine believes that the navel is most afraid of wind and cold invasion, and the Ren Meridian governs the uterus. Especially for women, if they do not pay attention to keeping the abdomen warm, wind, cold, summer heat and dampness can easily enter the human body through the navel, causing diarrhea, dysmenorrhea, etc.

Therefore, we have to cover ourselves with a quilt when we sleep to protect our bodies from the cold.

(1) Helps improve sleep quality. Scientific research has confirmed that a moderate quilt weight can give the body a gentle sense of pressure. This weight therapy can stimulate the tactile nerves, promote body relaxation, and reduce insomnia.

(2) Covering the belly button gives people a sense of security. Covering with a blanket can also bring a sense of psychological security, as if returning to the mother's arms, which comforts the soul and helps people fall asleep quickly.

(1) Do not touch your belly button casually to avoid inflammation or infection. If you encounter slight discharge, you can ignore it; if you detect odor, handle it gently, wipe it with clean water or mild lotion, and gently clean it after softening.

(2) Wear less belly-baring clothing. Regardless of the weather, your clothes should cover your belly button. Avoid wearing low-waist pants and belly-baring clothing to prevent cold air from invading and affecting your gastrointestinal health.

(3) Rub your abdomen before going to bed. Getting used to rubbing your abdomen before going to bed promotes health. The navel, called Shenque acupoint in traditional Chinese medicine, is a well-known longevity acupoint in health care, connecting the meridians and internal organs of the whole body. Rubbing the abdomen is a great way to regulate the internal organs. Before going to bed, lie on your back, fold your hands, and gently rotate counterclockwise and clockwise 50 to 100 times with your navel as the core to promote blood circulation and harmonize the internal organs.

So the advice of our elders is not without reason. When night falls and everything is quiet, please cover yourself with a blanket to protect your weak spot, your navel.
