Colds are a common illness that we have all experienced, and many people are torn between blowing the air conditioner in the summer after catching a cold. In the end, blowing a fan and blowing air conditioning which is more likely to make people cold, summer use of air conditioning and should pay attention to what? Today to talk about this topic.

First of all, people can not blow the air conditioning cold, cold, the body is particularly weak, thermoregulation is not normal, cold and hot and cold is easy to make the condition worse. From this point of view, the cold is not absolutely can not blow the air conditioning, but to pay attention to the method.

If the weather is particularly hot, the room is stuffy, not blowing the air conditioning simply can not stay, this time you can adjust the air conditioning temperature a little higher, generally 26 ℃ - 28 ℃ is more appropriate, do not let the cold wind blowing directly at the person.

And don't stay in the air-conditioned room, go out from time to time to get some air, so that the body can adapt to the outside temperature. If the temperature in the room is not so high, or cold symptoms are more serious, always runny nose, headache, fever, then try not to blow the air-conditioning, use a fan or open the window to cool down.

Besides, it is easy to catch a cold by blowing a fan or an air conditioner. In fact, whether it is a fan or air conditioner, it is easy to catch a cold if you do not use it properly. When blowing a fan, the fan rotates so that the air flow is accelerated, the sweat on the body evaporates quickly and feels cooler.

But if you keep blowing on a place, the local skin temperature drops, blood vessel contraction, over time, the body can not regulate, it is easy to get cold. Especially at night when you sleep, people fall asleep, the body does not react so sensitive, if the fan has been blowing, it is easier to catch a cold. Air conditioning is easy to catch a cold, mainly because the temperature in the air conditioning room is low, and there is a big temperature difference between the outside and the air conditioning room.

From the heat of the outdoors all of a sudden into the low temperature of the air-conditioned room, or from the air-conditioned room out to the high temperature of the outdoors, the body can not adapt to the temperature change, it is easy to catch a cold.

Moreover, air-conditioned rooms are usually closed and the air does not circulate, so if someone catches a cold, viruses and bacteria can easily spread in the room, increasing the chances of others catching a cold. Also, if the air conditioner is not cleaned for a long time, it hides a lot of dust, bacteria, blowing out the wind with these dirty things, be inhaled, but also easy to get sick.

What should we pay attention to when using air conditioners in summer? First of all, the air conditioning temperature should not be adjusted too low. Many people feel that the temperature is low enough to cool, the air conditioning to a dozen degrees, in fact, this is particularly bad. The temperature difference between indoor and outdoor temperature is best not more than 7 ℃, if the temperature difference is too large, especially easy to catch a cold. 26 ℃ or so, both cool and will not make the body too heavy, but also more energy-saving.

Secondly, the air conditioning wind direction do not blow against the person. Cold wind blowing directly on the body, it is easy to let the joints, muscles cold, causing headaches, leg pain. You can adjust the air conditioning wind direction to blow upward, so that the cold air slowly sink, so that the temperature in the room is more uniform, and will not blow directly to the person.

In addition, pay attention to the ventilation of the air-conditioned room. Air-conditioned room is closed, the air does not circulate, stay a long time, carbon dioxide concentration rises, oxygen content decreases, people will feel dizzy, chest tightness. It is best to open the window every once in a while, ventilation, fresh air, each ventilation 15-20 minutes on the line. If it is not convenient to open the window, you can also use an air purifier or fresh air system to improve air quality.

Also, air conditioners should be cleaned regularly. Air conditioning used for a long time, the filter, evaporator will accumulate a lot of dust, bacteria, mites, if not cleaned, blowing out the wind and dirty and unhealthy. Generally 1-2 weeks should be cleaned once the filter, you can remove it yourself and rinse it with water, and then soak it in disinfectant to sterilize it. Deep cleaning inside the air conditioner, it is best to find a professional to do, 1-2 times a year will do.

In addition to these, summer use of air conditioning there are some small details to pay attention to. For example, do not immediately enter the air-conditioned room when sweating, the first sweat dry, and so the body a little cooler before going in.

When you go to bed at night, you can set the air conditioning into sleep mode, the temperature is appropriately adjusted a little higher, and then cover a thin quilt to prevent catching cold. If you have an elderly person, a child or a weak person at home, you should pay more attention to the use of air conditioning and don't let them stay in the air-conditioned room for a long time.

In short, no matter when you have a cold, or usually use the air conditioning, you have to master the right way. Knowing this knowledge, you can make the air conditioning in the summer to better serve us, not only to enjoy the cool, but also to maintain good health, away from the trouble of colds.
