Using the fan for a long time
The electric fan has the function of regulating the air in the room, making the room more ventilated. Leaving the fan blowing for a long time in one position is not good for the body and also causes the motor to overheat, in the worst case can burn the motor.
It is best to turn off the fan once every 4-5 hours (about 30 minutes) so that the fan does not reduce its lifespan and protect the health of the user.
Fan speed setting too high
When the ambient temperature exceeds 30 degrees Celsius, which is close to body temperature, the wind blowing out from the fan is also wind at high temperature. Therefore, turning on the fan at the highest level will make the skin surface temperature decrease, the pores will close, sweat cannot escape, the body feels hotter, leading to fatigue, exhaustion and back pain. .
When using the fan regularly, you must remember to periodically clean the propeller, fan cage, brass motor shaft, … for the device to work effectively. A fan full of dirt will not be able to bring a clean cool breeze to the family, on the contrary, it will also quickly reduce its service life.
Use a fan when the body is sweating a lot
If you have the habit of walking into the house from outside in the hot sun, or after playing sports with sweat like taking a shower, immediately turning on the fan to cool off, this is a huge mistake.
When exercising vigorously, the blood vessels are dilated, sweat secreted a lot. The wind from the fan will stop the sweat secretion process, causing the blood vessels to contract suddenly, which is extremely dangerous.
You should take a dry towel to wipe away the sweat and then turn on the remote fan to cool slowly to ensure health safety.
Let the fan blow directly at you, above your head
When the wind blows directly on the body (with too much speed and close distance), the sweat evaporates quickly, the skin temperature drops significantly. As for the part without wind, sweat evaporates slowly, skin temperature is relatively high, skin blood vessels dilate. At this time, the blood circulation of the whole body is out of balance, so it is easy to catch the flu.
In addition, when the fan blows directly on the head and face, it is easy to cause headaches, dizziness, fatigue, stress… Therefore, when using the fan, you should sit far away and let the fan rotate in all directions. to avoid catching a cold.
The taboo position should not install an electric fan
Electric fans should not be hung above the sofa or bed because it will create “pulse peak pressure”, which adversely affects human nerves.
Wall fans should be installed at a certain height. Installing the fan too low will make users prone to headaches or neurological diseases. Therefore, if the ceiling is not high enough, you should only use a standing fan.
Do not place the fan in the White Tiger position
To locate Thanh Long and Bach Ho, you stand from inside the house looking out the main door: the left hand side is Thanh Long, the right hand side is Bach Ho. In which, Thanh Long is a lucky position and Bach Ho is a bad position. The position of Bach Ho should be “static”, not “dynamic”.
Placing the fan in the position of the Dragon fruit will help blow lucky air into every corner of the house. If you put the fan in the position of Bach Ho, the result will be opposite.
