Scientific health care needs to pay attention to small details. Xilinmen tells you six bad habits.
1. Wear a watch to sleep.

Some people like to wear watches to sleep, which will not only shorten the service life of watches, but also be harmful to health. Because watches, especially luminous watches, have radium radiation, although the amount is extremely small, experts believe that long-term accumulation will lead to adverse consequences.

Sleep with "teeth"

Some people are used to sleeping with dentures, and often accidentally swallow dentures when sleeping. The hook of denture may puncture the aortic arch beside esophagus, causing massive bleeding and even life-threatening. Therefore, people who wear dentures had better take them off and clean them before going to bed, which is not only beneficial to oral hygiene, but also safe to sleep.

Sleep under the hood

According to a survey of more than 5,000 women conducted by the Hawaii Institute of Civilized Diseases, women who wear bras for more than 12 hours a day are more than 20 times more likely to develop breast cancer than those who wear bras for a short time or don't wear bras at all. Women wear bras to show their beauty or protect their breasts, but it is not necessary to sleep at night.

4. Take the "machine" to sleep

Some people put their mobile phones at the bedside when they sleep at night, which is convenient for talking. American expert james cook pointed out that all kinds of electronic equipment, such as color TV sets, refrigerators, mobile phones, etc. In the process of use and operation, a large number of electromagnetic waves with different wavelengths and frequencies are released, forming electronic fog, which affects the disorder of human nervous system and physiological function. Although the release is very small, it is inevitable.

Step 5 put on makeup and sleep

Some women, especially young women, are often too lazy to take off their makeup before going to bed. It should be noted that sleeping with residual makeup will block your skin pores, cause sweat secretion disorder, hinder cell breathing, induce acne for a long time and damage your face. Therefore, you must remove makeup and wash your face before going to bed, which can remove the stimulation of residual makeup on your face in time, let your skin breathe fully, and only keep your skin moist, which will help you fall asleep as soon as possible.

6. Western medicine: Sleeping with wet hair can easily cause dizziness and nausea.

Rui Liu, a doctor at Beijing Puren Hospital, said that people who have the habit of washing their hair before going to bed at night are most likely to get sick if they don't dry their hair carefully and leave a lot of moisture on the scalp surface, especially when the temperature is low in winter. Sleeping until midnight will cause scalp numbness and persistent dull pain. The next morning, there will be inexplicable headache or dizziness, and in severe cases, nausea will occur. In the long run, it will also lead to a disease called "lower scalp phlebitis".

TCM: Sleeping without hair is easy to catch a cold.

Dr. Miao Qing from Xiyuan Hospital, Research Institute of Traditional Chinese Medicine said that in a day, people's yang is the weakest at midnight, and people tend to feel tired after a day's consumption, which shows that the activity of "defending qi" of human body is reduced, that is, the ability to resist cold is reduced. Therefore, if you wash your hair with hot water before going to bed, the dilated capillaries will be stimulated by the outside world. When the head is yang and cold, it will freeze the body, thus reflexively contracting the capillaries of the upper respiratory tract, reducing the local blood flow and the resistance of the upper respiratory tract, making the existing viruses or bacteria take advantage of it to grow and multiply, causing upper respiratory tract infection, thus causing cold symptoms, such as runny nose, stuffy nose, headache and even fever. So sleeping with wet hair is more likely to catch a cold.
