Recently, rong’er saw a news——
A 20-year-old college student in Jinhua, Zhejiang Province, washed his hair before going to bed one day, but went to bed without drying it. Who knows, when I got up the next day, I felt headache and dizziness, and my left eye could not help crying, and I could not close my eyes. After a day’s rest at home, she suffered from numbness on her left face, deviation of the angle of her mouth, laborious eating with drooling, and pain behind her left ear. Therefore, accompanied by her mother, she went to the Chinese medicine hospital for treatment. The doctor diagnosed facial paralysis and required hospitalization.

This kind of tragedy usually happens to women, especially college students and office workers. Because such women usually don’t have time to wash their hair during the day, they wash their hair later, and their hair is long and difficult to dry. They often can’t wait until their hair is completely dry, so they can’t help going to bed.
Although the probability of facial paralysis is slightly small, younger sister paper, who has the habit of sleeping with wet hair, can’t take chances. This habit seems to be “harmless” in the short term, but it is actually a cumulative harm to health.
hazard 1: easy to induce facial paralysis
Facial paralysis, the scientific name of facial nerve paralysis, is a common disease and frequently occurring disease, which is not limited by age. The general symptom is that the mouth and eyes are crooked, and patients often can’t even complete the most basic movements such as raising eyebrows, closing eyes, and drumming their mouths.
Why does washing your head cause facial paralysis? According to the doctor’s analysis, the facial nerve is at the most relaxed and has the lowest resistance when sleeping at night. If it is stimulated by the cold of wet hair, it is easy to affect the facial nerve behind the ear, resulting in local spasticity, thus inducing facial paralysis. The warm and timely weather in summer may not be so obvious, while the cold weather in winter has a great chance of causing facial paralysis.
hazard 2: causing colds
Traditional Chinese medicine believes that people’s Yang Qi is weakest at midnight. After a day’s consumption, women are easily exhausted physically and mentally, and their ability to resist wind and cold is also reduced. Therefore, if you wash your hair with hot water before going to bed, the dilated capillaries are stimulated by the outside world, and the Yang Qi of the head condenses when it is cold, the body will be frozen.
Moreover, after shampooing, a large amount of water will evaporate from the head, which will take away a lot of heat from the body. If immunity is low, heat dissipation will constrict capillaries of the upper respiratory tract and reduce local blood flow.
If the resistance of the upper respiratory tract decreases, bacteria and viruses may enter, causing upper respiratory tract infection and cold symptoms, such as runny nose, stuffy nose, headache and even fever. Therefore, it is easier to catch a cold when you sleep with your hair dry.
hazard 3: possible headache and dizziness
Rong’er had a headache. Once, I didn’t want to use an air dryer when I washed my hair before going to bed. I went to sleep directly before my hair was dry. As a result, I woke up the next day with a headache that I didn’t want. I don’t want to experience it again.
The main reason for headache is that moisture stays on the scalp surface for a long time, which will lower the scalp temperature and affect the blood circulation of the brain. Therefore, when you sleep in the middle of the night, you may feel numbness in part of the scalp, accompanied by continuous dull pain. In the morning of the next day, inexplicable headache or dizziness are more likely to occur, and serious people feel nausea.
In the long run, it may even cause a disease called “phlebitis under the scalp”.
hazard 4: bacterial breeding in pillows
Pillows are easy to breed bacteria if they are kept indoors for a long time. If you go to bed without dry hair, the moisture in your wet hair will permeate into the pillow core. Over time, the pillow core will turn yellow naturally.
The pillow materials that people often sleep on belong to the materials that are easy to get damp and moldy. A humid environment is more conducive to the growth of bacteria. In this way, the pillow has become a bacterial incubator, and its harm can be imagined. Although this sounds a bit alarmist, the truth is so cruel.
hazard 5: damage hair quality and style
Sleeping with wet hair is a devastating blow to hair style! When I got up the next morning, my hair was absolutely in a mess. It was inevitable to tie knots. I couldn’t cut it and cut it disorderly.
Why? Because the hair will be rubbed and squeezed when sleeping, it is easy to be bent into various shapes. When the hair dries, the softness decreases, and then it is shaped. It becomes a big problem that can not be solved by combing it. In addition, in this situation, it is more likely to cause hair breakage, damage to hair quality, and more serious, a lot of hair will fall out during combing. If you lose a lot of hair, be careful of being “extremely smart” and feel distressed.
In short, in short, girls should not take the risk of “sleeping with wet hair”. If you wash your hair before going to bed, no matter how busy you are, you should blow dry your hair before going to bed. The suffering of colds and colds has been enough. If you are really unlucky to encounter facial paralysis, it is a big event in “paralysis”!
