The fan blows on the head

In summer, many people choose not to turn on the air conditioner or those who do not have air conditioner at home will turn on the electric fan all day long because they think that electric fans are less harmful to the body than air conditioners. However, you must pay attention to learning the correct use of electric fans. This will not only save electricity, but also better maintain the health of the body. If the electric fan blows at the head for a long time, it will cause headaches and even induce stroke in some elderly people. Therefore, you must use electric fans appropriately in summer and never use them excessively.

Be careful of stroke if you blow towards your head.

It is best to choose a fan that can shake its head. If an electric fan blows directly at the head and neck, the scalp temperature will drop, and the reflex will cause the cerebral blood vessels to constrict, and cerebral blood flow will also decrease. For the elderly with cardiovascular and cerebrovascular diseases, it can induce cerebral stroke in severe cases.

In addition, if the fan blows towards one side of the face, there is a risk of causing facial paralysis. Although the cause of facial paralysis is unknown, it is currently recognized that local cold is one of the causes. This is because cold causes the blood vessels that nourish the nerves to spasm and contract, leading to changes such as nerve ischemia and hypoxia, edema, swelling, and compression degeneration.

Don't blow dry when sweating

When you come back from outside and are sweating all over, remember, it is not suitable to turn on the fan at this time, otherwise it will cause heatstroke or facial paralysis. It is recommended that you stay at home for a few minutes after returning home from outside and then turn on the fan to blow air.

Don’t blow dry after bathing

After taking a shower, the surface temperature of the human body drops, so it is not suitable to use a fan at this time. Also, because there is moisture on the skin surface, the heat can easily evaporate too quickly, leading to a cold.

The fan does not blow directly

Especially when you go to sleep at night, it is not suitable for the fan to blow directly towards your body. It is recommended that if you want to turn on the fan, you can let the wind be parallel to your body, as long as it causes air convection in the space.

The fan does not blow the head

The fan is the least suitable for blowing your hair. Blowing directly on your head will not only cause wind evil, but also cause migraines. This is especially true when you are drying your hair after taking a shower.

The fan does not blow for a long time

Fans are tools that should be turned off after half an hour at a time. Therefore, they are not suitable to be turned on all the time at night. After all, the temperature will naturally drop at night, and if you keep turning on all the time, there is a risk of catching a cold.

Don't blow dry when eating

When eating, remember not to blow in front of the fan. One reason is that the food will get cold, which is not conducive to digestion. Another reason is that if you blow in front of the fan while eating, a large amount of air will enter the stomach along with the food, causing gastrointestinal bloating.

Rain without wind

In rainy weather, the air is humid and especially hot and stuffy. It is recommended that you open the window directly and do not use a fan. Using a fan in rainy days will not have any effect. Instead, it will make the temperature even hotter.
