The popularity of air conditioners has almost eliminated the existence of fans in every household. However, in the opinion of health experts, hair fans are healthier than air conditioners. Especially for people who are relatively weak, they should pay more attention to the way of cooling in summer.
But it does not mean that having a fan is necessarily a healthy way to cool down. What diseases will be caused if the fan is incorrect?
1. Cold. Especially in the daytime, when the heat wave is rolling, everyone likes to blow the fan at the maximum gear, and the body becomes cold after blowing for a long time. In the evening, the temperature drops, causing difficulty in temperature regulation, decreased immunity, and a stuffy nose and throat cold.
2. Facial paralysis. Many people can do it when the fan is blowing in the face, but blowing in the face for a long time will lead to facial neuritis and cause mouth and eye deviation.
3. Gastroenteritis. The intestinal tract gets cold, and the local temperature is low, leading to hyperactivity or even spasm of the digestive tract, stomach pain, stomachache, and diarrhea.
4. Increase cardiovascular and cerebrovascular burden. The air flow is accelerated, and the heat is taken away with water to reduce the temperature, leading to the loss of body fluid. If water cannot be replenished in time, the blood viscosity will increase, which will increase the risk of aggravating the disease for patients with cardiovascular and cerebrovascular diseases.
