Why do you have a headache when you blow the air conditioner or even the fan for a long time?

It is important to blow air conditioners and fans in hot summer, because the weather is hot and cold. If there is no air conditioner and fan, everyone's health will be more painful, so it is necessary to use air conditioner and fan to cool the room at this time.

But many people find that they have a headache after blowing the air conditioner or fan. In fact, there are many reasons. When blowing air conditioners and fans, many people will stand near the wind source because of the hot and cold weather. Some people even saw the electric fan placed directly in front of them, keeping him close to his body and blowing at his body all the time.

Although you can feel cool quickly, you will find that after blowing for a while, the whole person will have a headache. This is because when the wind speed is faster, the sweat on the body surface actually evaporates faster. At this time, the temperature of the body will drop rapidly, and sweat will slowly evaporate on the side of the body that has not been blown.

Then its skin surface temperature will be relatively high. At this time, its body surface temperature is in a relaxed state, the temperature on one side of the epidermis is relatively high, while the temperature on the other side of the epidermis is relatively low. This will cause the blood circulation of the human body to lose balance, and sweat is also in an unbalanced state during excretion.

Therefore, dizziness, headache and even stroke are likely to occur. So when you blow an electric fan in your daily life, you must pay attention to the wind blown by the electric fan or air conditioner, and don't let it blow on your body.
