How to blow the fan correctly during the mild summer weather

　　With the arrival of the Xiaoshu solar term, the weather is hot, and fans have become the main tool for most people. Heatstroke prevention Cooling equipment. But some people use electric fans improperly, causing healthy bring harm, happen cold ,noodle nerve Paralysis, frozen shoulder, backache and other symptoms. How to use a fan correctly to help you cool down all summer? Next, the editor will tell you about the misunderstandings about blowing fans and how to use them correctly.

　　5 ways to use fans to harm your health

　　1. Hair drying for more than 1 hour

　　If you expose yourself to an electric fan for a long time, the body temperature will drop due to the evaporation of sweat, which can easily cause colds, colds, stomach ache、diarrhea wait disease . Generally, it is advisable to blow dry for half an hour to 1 hour at a time.

　　2. Wind speed is too high

　　When the temperature exceeds 30°C, the wind blown by the electric fan is also high-temperature wind. At this time, the body's heat should mainly be dissipated by evaporation of sweat. If the fan blows too hard, skin The surface temperature drops, the pores are blocked, the sweat inside the body cannot be emitted, and you will feel hot. At the same time, you will also experience fatigue, weakness, and back pain. This is "holding back sweat." Therefore, it is not advisable to use the electric fan to blow at high speed. It should be adjusted to medium or low speed to blow gentle breeze.

　　3. Fan placed too close

　　If a strong wind blows nearby and only blows on one side of the body, the sweat on the wind-exposed side of the skin will evaporate quickly and the temperature will drop significantly. On the other hand, the sweat on the side not exposed to the wind will evaporate slowly. Over time, you will feel general discomfort. Therefore, when blowing the electric fan, it is best to keep the distance from other people at least 2 meters away.

　　4. blowing directional wind

　　When blowing, the fan continuously moves its position and direction, and the blowing wind forms a big wave and a small wave, so that the body surface receives the wind more slowly, so that the person will not feel too cold, and the whole body temperature will be even.

　　5．sleep Tokibuki

　　When a person is asleep, the functions of various organs in the body are reduced to the lowest level, all reflexes disappear, immunity is reduced, and diseases are easily caused.

　　How to use electric fans correctly during Xiaoxiao Festival?

　　In the hot summer, it is very pleasant to turn on the fan and feel the cool breeze blowing on your face. However, many people get sick due to improper use of electric fans. The reason is that many people lack the knowledge to use electric fans. common sense。

　　Some people are too greedy for coolness and place the fan very close to the body and keep blowing it for a long time. In this way, the sweat on the side that is exposed to the wind evaporates quickly and the body surface temperature drops significantly. On the side that is not blown, the sweat evaporates slowly, the surface temperature is relatively high, and the blood vessels on the body surface are still in a state of relaxation. Eventually, the body's blood circulation is out of balance, and sweat excretion is also uneven. Symptoms such as headache, dizziness, general discomfort, etc. may occur. In severe cases, it can even induce stroke.； Some people suddenly blow hard with a fan when their body is too hot and sweaty, which can easily cause heat colds. ； If you turn on a fan while sleeping, it can easily cause a cold.

　　1. The wind speed should not be too high: Modern science believes that the indoor wind speed is best controlled at 0.2-0.5 meters/second, especially in rooms with good ventilation and in places with cross-ventilation. The wind speed of electric fans should not be too high.

　　2. It is not suitable to blow directly on people: blowing directly, wind evil can easily invade the body, especially when you are weak or sweating profusely, it is best to let the fan blow towards a corner.；

　　3. The fan should stop blowing and use a swing-head fan. For children, the elderly, and people with weak health, it is better to use the fan less to blow the air, because "where evil is trapped, the Qi will be deficient." However, an electric fan can be used to adjust the indoor airflow to indirectly cool down.

　　4. When you sweat a lot, do not blow the air immediately while sitting or lying down, because at this time, the blood vessels on the whole body surface expand and are suddenly blown by a cool breeze, which often causes vasoconstriction and stops perspiration immediately, causing the body's heat production and heat dissipation to lose balance, and excess heat cannot be excreted.；

　　5. After the cold wind blows, the local defense function decreases and viruses and bacteria invade, which can cause upper respiratory tract infection, muscle and joint pain, and some even abdominal pain and diarrhea. In short, you must pay attention to the method when using an electric fan, otherwise a good thing will turn into a bad thing, which will be detrimental to your health.

　　Let this summer be low-carbon

　　Use fan with air conditioner

　　Because the fan can directly convert electrical energy into kinetic energy, the power consumption is very low, with a maximum power of only 60W, which is equivalent to the power consumed by a table lamp for general lighting. Therefore, from the perspective of energy conservation, using a fan in midsummer is undoubtedly the best choice. Using a fan with an air conditioner and setting the air conditioner temperature at 26 degrees to 28 degrees can save energy and money.

　　Try to use medium or slow gears

　　As far as the use of the fan itself is concerned, generally fans with larger blades have greater electric power and consume more electricity. The power consumption of an electric fan is proportional to the speed of the fan blades. For example, a 400 mm electric fan consumes 60W when using the fast gear, and only 40W when using the slow gear. The power consumption of the same electric fan differs by 40% between the fastest gear and the slowest gear. One hour of power consumption on the fast gear can be used for nearly 2 hours on the slow gear. Usually, turn on the fast gear first, and then use the slow gear after cooling down, which can reduce the power consumption of the electric fan.

　　When in use, the fan is best placed next to doors and windows. This facilitates air circulation, improves cooling effect, shortens usage time, and reduces power consumption.
