What happens if a fan blows towards your face

Summer is here, and with it comes the heat wave. Many people want to turn on the fan all night and turn on the air conditioner when they sleep. They cannot live without fans and air conditioners. But can you imagine that simply blowing a fan at your face may cause symptoms such as headaches, dizziness, and general discomfort, and in severe cases may even induce a stroke. So what will happen if you blow a fan at your face? Are there any good solutions and tips? Let me introduce them to you in detail.

1. Causes

Place the fan very close to the body and keep it blowing for a long time. In this way, the sweat on the side that is blown by the wind will evaporate quickly and the body surface temperature will drop significantly. On the side that is not blown by the wind, the sweat will evaporate slowly, the skin temperature will be relatively high, and the blood vessels on the surface of the body will still be in a state of dilation, which will eventually lead to an imbalance in the body's blood circulation and an unbalanced sweat excretion. Symptoms such as headache, dizziness, and general discomfort may occur, and in severe cases, a stroke may be induced.

2. Guidance and Suggestions

(1) The wind speed of the electric fan should not be too high to allow the human body to adapt. The indoor wind speed should be controlled at 0.2-0.5 m/s, especially in well-ventilated rooms and places with drafts. The fan speed should not be too high.

(2) Electric fans should not be directed directly at people. If they are directed directly at people, cold winds can easily invade the body. Especially when people are weak or sweating profusely, it is best to direct the fan toward a corner. Children, the elderly, and people with weak bodies should use electric fans less often, because "where evil enters the skin, the qi will be weak", but electric fans can be used to adjust the indoor airflow to indirectly reduce the temperature. When sweating profusely, you should avoid getting close to an electric fan to avoid sweating problems on the body surface, which may lead to circulation disruption and easily cause a stroke.

(3) The air volume should not be turned on too high when sleeping. When people are sleeping, the body's circulation slows down, and this is when the body is most vulnerable. If the air volume is too high and blows directly at the body, it will cause the body to feel uncomfortable and weak, and in severe cases, a stroke may occur.

(4) It is not advisable to keep an electric fan on for a long time. There is an old Chinese saying that goes "Everything turns into its opposite when it reaches its extreme". If you keep an electric fan on for too long, your body will feel uncomfortable. The human body temperature will drop with the evaporation of sweat. Over time, it is easy to cause symptoms such as colds, abdominal pain, diarrhea, etc. It should be turned on appropriately. It is recommended to turn it on for about 1 hour.

(5) Correct placement is also very important. The electric fan should not be too close to the human body. If it is too close, the blood circulation and sweat circulation will be greatly affected, and the nerve center will be unbalanced. Once the time is too long, the various organs of the human body will feel tired, and the whole body will feel uncomfortable. The best place to place an electric fan is about 2 meters away from the human body, so that the wind is softer and more even.
