Many people like to blow the fan when they sleep, and blow directly at their body and head. When they wake up, they often feel sore all over. Although the body can relieve itself, the long-term fan blowing mode is wrong and the harm is very great.

Don't sleep with a direct fan

When the human body is in sleep, the epidermal blood vessels relax, the pores relax and the body surface temperature becomes relatively low. If the fan is blown excessively, the blood vessels of the body will contract and the blood flow will be blocked, resulting in muscle paralysis, muscle soreness, etc.

Don't blow the fan after sweating or bathing

After exercise or after taking a hot bath, blood circulation accelerates and pores dilate. If you directly blow the fan, your body is prone to shoulder pain, dizziness, runny nose and other symptoms due to alternating cold and heat.

Don't blow the head with the fan

Especially after sweating and just after washing hair, when the fan blows directly against the head, it will reduce the local temperature of the head and slow down the blood flow, resulting in the imbalance of blood flow in the whole head, and then cause headache.
