1, how about washing your hair at night?
In fact, it is the same to wash your hair at any time, but it is difficult to blow dry your hair. If you don't do it thoroughly, it will be harmful to your health. If you don't wash your hair thoroughly at night, it will be harmful to sleep. Therefore, it is best not to wash your hair at night.
Everyone knows that the scalp is very fragile. After washing the hair, the pores of the scalp will all open, and many bacteria will take this opportunity to breed on the scalp. Many people go to bed after washing their hair at night, which is easy to catch a cold and cause headaches after a long time.
If you wash your hair in the morning, on the one hand, you can keep your hair fresh and bright all day, on the other hand, from a health point of view, washing your hair in the morning can promote hair health. After washing the hair, the capillaries in the head are in a dilated state, which is very vulnerable to external stimuli. The yang in the head will condense when it is cold, the body will be frozen, and the capillaries will naturally contract, resulting in a decrease in blood flow in the head, which is very unfavorable for hair growth. How about washing your hair at night? Of course not. After washing your hair, your body's cold resistance will be reduced, viruses and bacteria will easily multiply and reproduce, and various cold symptoms will appear, such as sneezing, runny nose and stuffy nose.
Secondly, after washing your hair at night, wet hair will stick tightly to the pillow all night, and there is no room for free breathing, and your hair will gradually deteriorate. Especially in summer, most people take a bath before going to bed. On summer nights, we usually turn on the electric fan or air conditioner, which does more harm to our health and hair.
2. Disadvantages of washing your hair at night without drying it.
1, induced facial paralysis
Many girls don't dry their hair at night, and their mouths are crooked 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.
Step 2 catch a cold
Yang of human body has its own movement law. Chinese medicine believes that human yang is the weakest at midnight. After a day's consumption, women are easily exhausted physically and mentally, and their ability to resist the cold is also reduced.
Therefore, if you wash your hair with hot water before going to bed, the dilated capillaries will be stimulated by the outside world, and the head yang will freeze when it is cold and condensed. Moreover, after washing the head, the head will evaporate a lot of water and take away a lot of heat in the body.
If the immunity is low, heat dissipation will shrink the capillaries of the upper respiratory tract and reduce the local blood flow. If the upper respiratory resistance is reduced, bacteria and viruses may enter, causing upper respiratory infection and cold symptoms, such as runny nose, stuffy nose, headache and even fever. Therefore, it is easier to catch a cold when sleeping without dry hair.
3. Headache and dizziness
If you don't blow dry your hair before going to bed, it is easy to cause wet and cold to invade 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 pins and needles, accompanied by dull pain.
If you don't blow dry your hair before going to bed, it is easy to cause wet and cold to invade your body. Cause a headache
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".
3. Correct shampoo method
Get ready before washing your hair.
Comb the tangled hair slowly from the end of the hair, then comb it from the root to the end, or even comb it head-down from the brain spoon, which can make the hair smooth, improve blood circulation and clean it with half the effort! It can also make the oil fully moisturize the hair on the whole scalp, and it can also brush off dead cells and fallen hair on the scalp.
This step is very important, especially for people with dry hair. It can stimulate blood circulation and oil secretion, thus making hair more moist.
4. Hazards of washing your hair at night
I am in a hurry to go to work in the morning, but I have no time at noon. It is most appropriate to solve the problem of shampoo when taking a bath at night, so it becomes the same time for most urban white-collar workers to shampoo at night. Some of them also think that using a hair dryer will hurt their hair, but they always blow it carelessly.
After washing your hair at night, it is of course best if you have enough time to let your hair dry thoroughly before going to bed. But sometimes after 10 at night, I'm too busy to wash my hair. After washing my hair, I was so tired that I couldn't open my eyelids and fell asleep before my hair dried.
Washing your hair and sleeping wet at night is a big no-no. Sleep with wet hair and air conditioning on. When I wake up the next day, I often feel headache and fatigue. This is because in a day, people's yang is the weakest at midnight, and they are prone to fatigue and have low disease resistance. Shampooing before going to bed makes water stay on the scalp, which will lead to qi stagnation and blood stasis for a long time, and the meridians are blocked. Moreover, sleeping in an air-conditioned bedroom after washing your head and blowing your head against the cold wind will lead to dampness and cold. Many people sleep until midnight, and their scalp is numb and accompanied by pain. In the long run, it will also lead to a disease of phlebitis under the scalp.
If you fall asleep when your hair is not dry, the regulation function of the thermoregulation center is low at this time, and you are more likely to catch a cold.
Therefore, generally speaking, it is best not to wash your hair before going to bed. If you want to wash it, dry it with a dry towel, and then blow dry your hair with a hair dryer before going to bed, so that you won't catch a cold.
