Many women often go to bed with wet hair, especially college students and office workers. Because they usually don't have time to wash their hair during the day, they wash their hair late at night. Their long and hard-to-dry hair often doesn't fully dry before they go to bed, so they can't resist the temptation to sleep with wet hair. This habit of sleeping with wet hair may seem harmless in the short term, but it actually accumulates damage to health over time.
【Causes Facial Paralysis】
When sleeping at night, the facial nerves are at their most relaxed and least resistant. If they are exposed to the cold stimulation of wet hair, it is easy to affect the facial nerves behind the ears, causing local spasms and resulting in facial paralysis.
【Causes Cold and Flu】
Traditional Chinese medicine believes that the body's yang energy is weakest at midnight, and after a day of consumption, women are easily physically and mentally exhausted, with reduced ability to resist wind and cold. Therefore, if the dilated capillaries in the head are stimulated by the external environment after washing the hair with hot water before sleep, the yang energy in the head will condense when it encounters the cold, causing the body to freeze and easily triggering a cold.
【Causes Headaches and Dizziness】
The main cause of headache is the long-term accumulation of moisture on the scalp, which lowers the scalp temperature and affects the blood circulation in the brain. Therefore, when sleeping in the middle of the night, one may feel numbness in the scalp area, accompanied by a lingering dull pain. In the early morning of the next day, there may be unexplained headaches or dizziness, and in severe cases, nausea may occur.
【Breeds Bacteria】
Pillows kept indoors for a long time are already prone to bacterial growth. If you go to bed with wet hair, the moisture on the wet hair will seep into the pillow core. Over time, the pillow core will naturally turn yellow.
【Causes Hair Loss】
Sleeping with wet hair has a serious impact on the health of the hair and can easily lead to hair loss.
In conclusion, it is recommended that everyone change the habit of sleeping with wet hair as soon as possible. If you wash your hair before sleep, no matter how busy you are, make sure to blow dry your hair before sleeping.
