Electric fans are tools used to drive away high temperatures in summer, but there are always people who, due to improper use, directly cause physical discomfort, such as body acid, dizziness, mainly due to improper use of electric fans. Therefore, how to avoid these wrong practices should be read the precautions for using electric fans. Precautions for using an electric fan, which provides a detailed description of common situations and discomfort during use. It should be modified according to one's own problems and should not harm the body for the sake of temporary coolness. The specific steps are as follows:
Precautions for using electric fans
1. Long term blowing
Many people love to blow on electric fans for a long time. They feel that if they just stop blowing when they cool down, they may feel hot on their bodies and feel more comfortable blowing them for a long time. However, if you blow on an electric fan for a long time, the body temperature will decrease with the transpiration of a lot of sweat, which can easily cause diseases such as colds, colds, abdominal pain, diarrhea, etc. Generally, blowing for about half an hour is very proud.
2. High speed blowing
(1) Some people, in order to cool down as soon as possible, turn on the electric fan to the highest speed and believe that the strong wind is enough to relieve heat. This approach is not good. When the temperature exceeds 30 ℃, the air temperature is close to the normal body temperature. The wind blown by the electric fan is also high-temperature wind. At this time, the heat of the human body should be dissipated by the evaporation of sweat.
(2) If the electric fan is blown too hard, the surface temperature of the skin drops, the pores are blocked, and sweat cannot be released from the body, it will also feel hot, and fatigue, weakness, and back pain will also occur, which is called "holding sweat". Therefore, it is not advisable to use an electric fan for high-end high-speed blowing. It should be adjusted to medium or low speed, and gentle bursts of breeze should be blown.
3. Blow near the wind
(1) Electric fan hair dryers should not be placed close to the body. If strong winds are blown in close proximity and only one side of the body is blown, the skin sweat on the affected side will evaporate quickly and the temperature will significantly decrease. On the side that cannot be blown, the sweat will evaporate slowly, causing a large gap between blood circulation and sweat secretion on both sides of the body, and the nerve center will lose balance.
(2) Once the time is too long, various organs will become exhausted and feel unwell throughout the body; When blowing an electric fan, it is best to keep a distance of 2 meters away from people to ensure that the blowing wind is even and soft.
4. Blow a steady wind
Nowadays, electric fans are mostly head shaking fans. When blowing, the fan constantly moves in direction and direction, creating large and small bursts of wind, allowing the body surface to receive the wind slowly and not making people feel too cold, and feeling a uniform temperature throughout the body. So, it's best to use a shaking head fan instead of blowing directional wind.
5. Sleep and blow
By using an electric fan to cool down while sleeping, the function of various organs in the body decreases to the lowest level during deep sleep, and all reflexes disappear, leading to a decrease in immune function and easily causing diseases.
