Why does it cause facial paralysis without drying?
Actually, cases of facial paralysis appear several times during the summer.
Because the human body is more prone to sweating in summer, the pores are in a state of expansion at this time. Prolonged blowing can cause severe constriction of blood vessels, and over time, local swelling and compression of facial nerves will occur, resulting in facial nerve paralysis.
And this woman may directly ride a bicycle after washing her head, and the facial paralysis is caused by the stimulation of cold and heat.

A bad hair wash can also hurt your body
For this kind of everyday thing, there are also many details to consider when washing your hair. However, some people think that the time of shampooing is very particular, and if the time is not right, it may damage the hair or human health.
Shampooing your hair in the morning or in the evening, which time is better?
Actually, it’s not that strict when it comes to washing your hair.
Some people feel that getting up in the morning and washing their hair can start a new day of work and life refreshed; some people think that washing their hair before going to bed can get into the bed neatly and prepare to rest and sleep.
Therefore, if you already have the habit of washing your hair at a fixed time, and you are not uncomfortable after washing your hair, you can wash your hair according to your own time plan. There is no “best time” “.
However, it should be emphasized that although there is no set time for shampooing, the temperature of shampooing water needs to be kept moderate.
Hot water will dilate the blood vessels on the surface of the scalp, and too cold water will stimulate blood vessels to constrict. Excessive dilation or contraction of blood vessels will cause physical discomfort.
For patients with cerebrovascular disease, too cold or hot water temperature may stimulate the occurrence of the disease, resulting in dizziness, headache and other phenomena.
In addition, after washing your hair, be sure to blow dry your hair. You need to wait until your hair is completely dry before going out or going to bed. If the hair is wet, the evaporation of water will take away the heat of the head, causing the scalp blood vessels to be stimulated by cold and heat, which will cause health risks.
How often is the best time to wash your hair?
Actually, there is no particularly accurate statement on how often to wash your hair, it mainly depends on the quality of your hair.
1. Oily hair
If you have oily hair and your scalp often produces oil that makes your hair look greasy, then washing your hair once a day should do the trick.
Because the hair and scalp cannot be cleaned in time, oil may clog the hair follicles, affect the absorption of nutrients by the hair, and even lead to hair loss.
2, dry or normal hair
If your hair doesn’t produce a lot of oil, then you have normal or dry hair. In this case, it is better to wash your hair every two or three days.
If your hair loss is serious, you can reduce the number of times you wash your hair and choose a suitable shampoo.
Some people may have a cleanliness addiction and wash their hair once in the evening shower, but have to wash their hair again when they wake up the next morning.
Actually, this approach is wrong.
If you wash your hair too many times a day, it is easy to damage the sebaceous glands on the scalp, resulting in a significant loss of oil, thus losing the natural protective film of the scalp and hair , thereby causing more damage to the hair quality.
Shampoo, but not too hard
Some friends think that scratching the scalp with nails will feel very comfortable and refreshing.
But in fact, rubbing and pulling too hard may inadvertently scratch the scalp, causing some inflammation on the scalp, or stimulating damaged hair follicles, causing hair loss.
It is recommended that during the shampooing process, the intensity is moderate, and the scalp and hair should be gently rubbed from front to back with the pulp of the fingers. Damages hair, causing hair loss and hair loss.
