Recently, the hot weather is coming
All kinds of "cooling artifacts" began to sell well
Neck-mounted portable electric fan
It's loved by everyone
This fan is easy to use
But there may be risks
A 7-year-old boy in Nanning, Guangxi
Just because I slept with a halterneck fan
As a result, his face was paralyzed
↓↓↓
It is understood that the 7-year-old boy likes to wear a halterneck fan because he wants to be cool, whether outdoors or at home. One day at noon, the boy fell asleep wearing a halterneck fan, but when he woke up, he found that his face was blown crooked, and his face was paralyzed.
According to the doctor, the reason why the 7-year-old boy was blown into facial paralysis was due to the poor flow of meridian qi and blood after the fan was blown on a part of the human body for a long time. Usually, there is no big problem for everyone to use the neck fan for a short time, but "too much", especially for children and the elderly, if the neck fan is blown on the face, head and neck for a long time, it is easy to cause facial paralysis or even more serious diseases.
There are also quite a few on social platforms
Improper use of cooling equipment such as air conditioners and fans
Cases of facial paralysis↓
The halterneck fan is convenient though
However, here are some of the hazards to be aware of
↓↓↓
1. Some products have design defects
At present, the neck fans on the market are generally made of plastic, and some products have large gaps in the mesh fan cover, and in the process of rapid rotation of the fan blades, users are likely to be scratched by accidentally touching the fan blades. However, the product design of some neck-mounted electric fans is not reasonable, which can easily cause the hair to be caught in the rotating fan blades, thus damaging the scalp.
2. There is a risk of fire
The sales price of the neck-mounted portable electric fan is often between twenty or thirty yuan and nearly 100 yuan, and the reason for the price difference is mainly due to the inconsistent quality of the lithium battery used. If the product uses a counterfeit lithium battery, it may cause an explosion or fire.
3. It is easy to "accidentally injure" children
In terms of product appearance, many small fans with halternecks use cartoon images and colorful shells, which are easy to be used as toys by children. If you accidentally touch the switch, your child's fingers will touch the fan blades, and they are likely to get injured. It should be noted that the national mandatory standard clearly stipulates that "the shape and decoration of the shell of the appliance should not make the appliance easy for children to use as a toy".
4. Blowing the neck fan directly may cause facial paralysis
Zhang Zhi, director of the Department of Neurology of the Second People's Hospital of Hefei, once treated a patient with facial paralysis caused by blowing a neck fan. "The fan blows on the patient's cheeks, which is exactly where the facial nerve emerges from the skull, which is relatively weak, and if the fan or air conditioner blows directly at this part, it is easy to be invaded by the virus, causing common facial paralysis, also known as facial neuritis." "Patients with facial paralysis are prone to symptoms such as crooked corners of the mouth and weak eyelid closure." Zhang Zhi said that in addition to causing the above symptoms, hanging a fan or ice ring directly on the neck will also cause the physiological curvature of the cervical spine to straighten, which will have a certain impact on the cervical spine and the nerves and blood vessels of the neck. "The most common ones are neck and shoulder pain, cervical spondylosis, and in severe cases, it can also cause blood vessels in the neck to constrict and reduce blood flow, leading to the occurrence of cerebrovascular disease."
How to choose and use it correctly?
Experts remind
↓↓↓
●When purchasing and using a neck-mounted portable electric fan, purchase the product through regular channels;
● Before purchasing, observe whether the surface of the product is smooth and flat, and whether there are risks in the gaps of the fan cover;
●Strictly abide by the instructions in the manual, use the product correctly, and if there is any abnormal situation such as smoke and abnormal noise in the process of use, the power should be cut off quickly;
●Avoid using the neck-mounted portable electric fan for a long time to prevent diseases caused by neck and facial cold;
● Be careful not to let water or metal objects enter the inside of the electric fan when using, so as not to cause a short circuit in the power supply;
● Remember to use the charger provided by the manufacturer when charging, and do not replace other charging equipment at will;
●It is best to place the electric fan out of the reach of children to prevent accidents.
And these few things
Don't do it no matter how hot it is

1. Blow directional wind
The hazards are just like the neck fans mentioned above. The correct way to use it is to shake the head fan, so that the wind blown by the electric fan constantly moves the position and direction, so that the blowing forms a large and small burst, which will make the body surface wind slower, not make people feel too cold, and feel the temperature of the whole body is uniform. So, it's better to use a shaking head fan and not blow directional winds.
2. Add ice and water to the wind
In the high temperature, many people think that the air coming out of the electric fan is hot, so they add water or put ice. However, the surface temperature of the human skin drops too quickly, the pores are blocked, the sweat inside the body cannot be released, and it will feel hot, and at the same time, fatigue and weakness, back pain will occur, which is "sweating".
Dr. Liu Zhongxing reminded everyone that this will gather "wind, cold and dampness", and the evil qi will invade the human body unconsciously, so we must have a sense of protection and don't be greedy for cold.
3. Blow near the wind
If a strong wind blows nearby, and only one side of the body is blown, the sweat of the skin on the windy side will evaporate quickly and the temperature will be significantly reduced.
On the side that does not blow the wind, the sweat evaporates slowly, resulting in a large gap between the blood circulation and sweat excretion on both sides of the body, and the nerve center will lose its balance, and once the time is too long, the organs will be exhausted, and the whole body will feel uncomfortable.
