4 mistakes to avoid when using electric fans in hot weather.
Dr. Osamu Nishizaki, Director of Nishizaki Hospital in Japan, stated that prolonged exposure to air blown from fans can affect the body's natural thermoregulation mechanism, harming health.
"Electric fans reduce the surface temperature of the skin and internal organs through the blood circulation mechanism, causing feelings of fatigue, weakness, stress, headaches, and loss of appetite."
You should avoid the following habits when using electric fans to prevent harm to your health:
The fan blows directly onto the person and head.
Direct airflow from a fan at high speed and close range causes sweat to evaporate quickly, lowering skin temperature, disrupting blood circulation, and increasing susceptibility to colds and flu. Blowing air directly onto the head can cause headaches, dizziness, and fatigue. Users should position the fan facing a wall or ceiling for better air circulation.

Use a fan while sleeping.
While sleeping, the human immune system and internal organs rest. Prolonged exposure to fan drafts can easily cause colds, runny noses, and sore throats. You should use the fan at a medium speed, about 2 meters away from you, rotating in all directions, and setting a timer to turn it off.
Use a fan when you're sweating a lot.
When your body temperature is high, or you're sweating profusely from exercise or coming in from outside, you shouldn't sit in front of a fan to cool down. Instead, you should drink plenty of water, dry yourself off, and only use a fan to cool down gradually once your body temperature has stabilized.
The fan speed is set too high.
The higher the wind speed, the faster the sweat on the skin evaporates, clogging pores and making the body feel hotter, leading to fatigue. Users should adjust the fan to a moderate speed to create a gentle breeze, enough to make the body feel comfortable.
