Is it good to blow a fan in the summer? Why do I have headaches?

Don't blow overnight!

It's easy to get dizzy, dizzy, and of course, it's easy to catch a cold!

There is also the old man who often says, it is easy to let the wind into the stomach!!

What to pay attention to when blowing an electric fan:

In the hot summer, turn on the electric fan, the breeze blows, so comfortable, but there are many people who get sick due to improper use of electric fans, and the reason is that many people lack the common sense of using electric fans.

Some people are too greedy for coolness, so they put the fan very close to their body and blow it for a long time. In this way, the sweat evaporates quickly on the side that can be blown into the wind, and the body surface temperature drops significantly, and the side that is not blown is slow to evaporate, the epidermal temperature is relatively high, and the blood vessels on the body surface are still in a state of relaxation, which eventually leads to the loss of balance in the body's blood circulation, and the sweat excretion is unbalanced, and symptoms such as headache, dizziness, and general malaise may occur, and severe strokes can also be induced.

When some people are too hot and sweaty, they suddenly blow with an electric fan, which is easy to cause heat cold; If you also blow the fan while sleeping, it is easy to cause a cold.

How to use the fan correctly?

First of all, the wind speed should not be too large: modern science believes that the indoor wind speed is best controlled at 0 2-0 5 meters per second, especially in the room with good ventilation and in the place where there is too much wind, the wind speed of the fan should not be too large.

Secondly, it is not advisable to blow directly on people: blowing directly, wind evil is easy to invade the body, especially when the body is weak or sweating, it is best to let the electric fan blow towards a corner; For children, the elderly, and people who are weak, it is better to use less electric fans to blow the air, because "where the evil is, its qi will be empty", but you can use an electric fan to adjust the indoor airflow, so as to indirectly cool down.

Finally, it should be noted that when you sweat a lot, do not immediately blow the wind in the situation of sitting or lying still, because at this time, the blood vessels on the surface of the whole body are dilated, and the sudden cool breeze blows will often cause blood vessels to constrict, and sweating will stop immediately, resulting in the loss of balance between heat production and heat dissipation in the body, and the excess heat will not be excreted; In addition, after the cool breeze blows, the local defense function decreases, and viruses and bacteria invade, which can produce upper respiratory tract infection, muscle and joint pain, and some even abdominal pain and diarrhea. In short, we must pay attention to the method of using electric fans, otherwise good things will become bad things, which will be bad for your health.

Blowing the fan must not blow to people for a long time, the fan blowing for too long will destroy the balance of sweating, you can take the action of letting the fan blow the wall to promote air circulation.

When people sleep, they will automatically be in a state of low temperature perspiration, and it is not good to blow the fan all the time. It is easy to catch a cold when sleeping. My mom told me that I've been playing and being careful of strokes.,I don't know why.,But I believe it.,My mom is a doctor.。。。

So you better not blow it all night. If you have a cold, it's not good.

Because blowing the fan will take away the surface moisture, evaporation and heat absorption, causing the body to be cold, causing headache, fever, brain fever, etc.

Blowing the fan for too long can disrupt the balance of sweating, so it can cause headaches, dizziness, leg soreness, general malaise, and in severe cases, other diseases.

Don't blow on your body all the time, you won't feel comfortable if you can't sweat!

Don't blow at one part and swing your head

Don't get too close.

Blowing a fan on the head can be very harmful:

1. If you use an electric fan to blow the air on your head for a long time, your body temperature will decrease with the evaporation of a large amount of sweat, and over time, it is easy to cause cold, fever, diarrhea, abdominal pain and other symptoms.

2. It will increase the gap between blood circulation and sweat circulation, and the nerve center of the brain will lose balance, causing all organs of the human body to feel tired, thus causing general discomfort.

3. It will cause damage to blood vessels, reduce cerebral blood flow, and eventually cause brain cells to be damaged or die.

The weather this year is actually quite strange, it has been a few days in June to feel a little hot, so every household has taken out the electric fan, maybe many places have begun to use air conditioning, but now it is not so hot, so most people will choose to fan the fan is enough, but many people may find that the fan overnight, the head will be particularly painful in the morning, I don't know why this happens, so why does the fan have a headache? What should I do if I have a headache with a fan?

1. Problem analysis

Many people may feel the heat will blow on the fan all the time, the fan may make people feel cool, but it will also bring a lot of fan diseases to people, such as dizziness, weakness, headache, shoulder pain, runny nose and other symptoms, all belong to what we call fan disease, when people evaporate a large amount of sweat under the fan, the temperature of the surface of the ** will slowly drop, and the blood vessels of the body will slowly contract, but the temperature on the side away from the electric fan has not dropped, on the contrary, the blood vessels are expanding, so it is easy to cause an imbalance in the temperature of the human body. The part that has been blowing the fan may suddenly feel uncomfortable, and the central nervous system cannot be adjusted all at once, so it is easy to catch a cold, which can lead to headaches.

2. Solution

You can use ice to relieve the headache, put an ice pack or a towel with ice water on the headache, and the headache will be relieved slowly. You can also reduce the headache by massaging the head, mainly by pressing the temples, with just the right amount of force, not too heavy and not too light. Find a quiet place to sleep well, remember not to blow into the fan when you sleep, and if you have symptoms of a cold, you can drink more cold boiled water.

3. Pay attention to it

Remember to prevent fan disease when fanning, don't adjust the wind of the fan too much, blow the fan for too long, and remember that the fan should not be too close to yourself, don't keep letting the fan blow in one place, you can set the fan to shake the head, which can reduce the chance of suffering from fan disease.
