What harm does fan often blow fan to have?
4hw.org: it's hot in summer. Many people like to stay under the air conditioner. They want to keep cool. Some people even let the air conditioner stay up all night. In fact, there are many dangers in blowing the air conditioner for a long time. Recently, there is a little girl who blows the air conditioner and fan all night, and then suffers from facial paralysis. What's the matter? What are the dangers of blowing the air conditioner? Let's have a look at the details!
It is understood that facial paralysis is facial nerve paralysis, commonly known as "crooked mouth", "crooked mouth", "facial neuritis", "crooked mouth wind", etc., which is a common and frequently occurring disease characterized by the movement dysfunction of facial expression muscle group, with the general symptoms of mouth and eye crooked and not limited by age. After the disease, the patient's face is often difficult to complete the most basic actions such as eyebrow raising, eyes closing, mouth bulging, etc.
"Many people, including children, who sweat a lot after sports like to turn on their fans or air conditioners as soon as they enter the room and blow directly at the air outlet. Feng BIHONG, deputy chief pediatrician of the hospital, said that the sudden cold wind would invade the facial microcirculation, stimulate the contraction of facial nerves and blood vessels, affect the blood supply barrier, and cause facial paralysis.
Under the hospital's care, although Jiajia's mouth angle was still askew compared with the children with normal face, she said it was better and the muscles on her face were not very uncomfortable. 'it's too hot and sultry. I went to bed at night and blew the electric fan all night. That's how I got up in the morning. 'said Jiajia's mother.
It is reported that since this summer, Jiajia has been the second patient with facial paralysis in the ward.
Feng BIHONG also said that if you want to cool down in hot summer, you should avoid blowing hard at the air conditioner and electric fan. The electric fan should be placed in a little distance. Use a breeze or shake your head. Don't face the face and joints. You should always prepare a blanket and wrap it around your abdomen and joints before you go to sleep. In case of facial paralysis symptoms such as angle of mouth askew and difficulty in closing eyes, diagnosis and treatment should be carried out in a regular hospital in time.
The normal fan has the following hazards:
1. The blower fan is easy to catch cold. The fan will make the water on the body surface evaporate rapidly, and the evaporation of water will make the temperature on the body surface drop rapidly, so it's easy to catch a cold, especially if it's already cold, it will aggravate the disease, and then it's more serious to eat when sleeping.
2. Affect the secretion of body fluids and endocrine disorders. Blowing the fan will only reduce the temperature of the body surface, and the sweat glands and pores will be closed. In this way, the temperature inside the body cannot be reduced, but it will be higher, and there will be headache, nausea and other symptoms.
3. It's not good for joints. For a long time, blowing the fan will cause joint pain and even arthritis. This is because the joint temperature is very low when blowing the fan, and the temperature is very high when leaving the fan. Such a cold and hot joint is unbearable.
Note: blowing the fan is not a good thing, like drinking poison to quench thirst, especially when you are sleeping, you must not blow it directly.
