Should the electric fan blow its head or feet?
I have seen and heard many arguments: "Should electric fans blow their heads or feet?" People who insist on blowing to the head think that if the head is afraid of heat, it is of course blowing to the head. People who disagree think that blowing on the head is easy to catch a cold and have a headache. At first glance, it seems that "the public is right and the old woman is right." For a while, I didn't know how to place the electric fan correctly.
In fact, if you have to choose one, you might as well not blow the fan under your feet.
As the saying goes, "cold comes from the soles of your feet", and Chinese medicine also says that "it is better to take medicine to warm your feet with cold head". Cold head and warm feet are considered as an important principle of health care. The foot is farthest from the heart and located at the bottom of the human body. Once it is cold, its blood return will be blocked, which will cause meridian obstruction and easily lead to various diseases.
On the contrary, the head has sufficient blood supply and is the most cold-resistant-that is, it is most afraid of heat. Before the birth of electric fans, our ancestors used fans to cool the air. Even now, there are still many old people who like to gently shake the cattail leaf fan to enjoy the cool. You can observe that they are all slapping their heads, only occasionally, they are patting their feet. Their main purpose is probably to repel mosquitoes more than to remove heat. This is because, under normal circumstances, as long as the head does not feel hot, the body will not feel irritable and uncomfortable.
Therefore, it is unhealthy to put an electric fan at your feet and let it blow against your feet. Of course, it is not appropriate for the fan to blow directly at the head all the time.
The most suitable method is to let the fan shake its head naturally and speed up the air flow in the whole room, so that the indoor temperature will be lowered and the human body will feel more comfortable.
Are you clear? The electric fan can't blow your head and feet, so it's best to shake it!
