What are the hazards of not drying your hair after washing?

It's a big disadvantage. It must be a bad habit.

Laziness is a common problem for us girls. Many people often leave their hair alone after washing it in winter. They go out with water droplets in their hair, and then they have all kinds of discomfort. But this habit will do great harm to their health.

1, chronic headache: If you don't blow dry your hair before going to bed, it will easily lead to wet and cold invading your body. The main cause of headache is that water stays on the scalp surface for a long time, which will reduce the temperature of the scalp and affect the blood circulation of the brain. Therefore, when you sleep in the middle of the night, you may feel scalp numbness and dull pain. The next morning, inexplicable headaches or dizziness are more likely to occur, and serious people feel sick. In the long run, it may even lead to a disease called "lower scalp phlebitis".

2. Cold: Girls don't blow their hair after washing, but when the water evaporates, it will take away the heat. If the ambient temperature is also low at this time, they may catch a cold because of catching cold.

3, hair loss: If girls do not blow their hair after washing their heads, because there is more water on the scalp, bacteria may multiply in large numbers, thus affecting the development of hair follicles. In the long run, you may lose your hair.

4, induced facial paralysis: many girls do not blow dry their hair at night, get up very early in the morning. Facial paralysis, scientific name facial paralysis, is a common and frequently-occurring disease, regardless of age. The general symptom is that the mouth and eyes are skewed, and patients often can't even complete the most basic actions such as raising eyebrows, closing their eyes and bulging their mouths. Why wash your hair and wash out facial paralysis? According to the doctor's analysis, when sleeping at night, the facial nerve is in the most relaxed state and the resistance is the lowest. If stimulated by cold and wet hair, it will easily affect the nerves behind the ear, leading to local spasm, thus inducing facial paralysis. It may not be so obvious when the weather is warm in summer, and it is very likely to cause facial paralysis when it is cold in winter.

5. It will cause bacterial growth in pillows: high temperature in summer is the high season for bacterial growth. If the hair lies directly on the pillow in a wet state, the pillow will become wetter, which is beneficial to the growth and reproduction of bacteria and harmful to health.

6, prone to white hair: hormone secretion is the most vigorous at night, but if the scalp is wet, the blood vessels in the hair follicle are in a state of contraction, which will inhibit the secretion of melanocytes and easily grow white hair for a long time.

7. Others: If it is menstrual period, girls do not blow their hair after washing their hair. Because the pores are open, cold air may enter the body. If cold air enters the uterine cavity, it may also induce dysmenorrhea.

So don't be lazy. If you wash your hair before going to bed, be sure to dry it before going to bed. Otherwise it's just a headache, dizziness, cold and fever. If you accidentally become facial paralysis like the little girl in the news before, don't think about it. It's really a big deal!
