What are the health threats caused by staying in an air-conditioned room for a long time?

It's getting hotter and hotter recently, and people are always sweating. Many people spend their summer by air conditioning, but too much air conditioning is harmful to their health and easy to get "air conditioning disease". Some people may not know that it is because the air conditioner "blows". Today I will tell you some related knowledge ~

1, dry skin &; Sweating system is affected.

Many people have noticed that if you stay in an air-conditioned room for a long time, your skin will become very dry, because the general household air conditioner only controls the temperature of the air, without humidity control. In order to ensure the cooling effect, the air outlet and wind force of the air conditioner are very strong, which makes the indoor air dry, and the skin will become dry and dehydrated after a long time. If the skin loses moisture further, there may be slight itching.

The human body has its own temperature regulation system. If you stay in an air-conditioned room for a long time under the temperature environment of manual intervention and adjustment, it will affect your own temperature adjustment, and your pores will shrink due to cold, which may lead to the closure of sweat glands and affect your perspiration system. You may not be able to sweat normally for a long time. Perhaps what others often say "it's good to sweat occasionally" is really reasonable.

2, facial nerve disorder

It is what we commonly call "facial paralysis". Children and the elderly are more likely to appear, because the cold wind will stimulate the rapid contraction of hair blood vessels, leading to poor blood circulation, and even serious symptoms of facial nerve disorder. d

3. Upper respiratory diseases

The air-conditioned room itself is a relatively sealed space. When the air conditioner is turned on, the doors and windows are closed and the air is not circulated. Once the human body is broken by cold air, it is prone to cough, runny nose, dry throat and other upper respiratory diseases, which are actually similar to colds. If you are in poor health, bacteria may enter the lungs through breathing, causing pneumonia!

Some friends with rhinitis sneeze more frequently if they stay in an air-conditioned room for a long time.

4, joint pain

In summer, many people like to wear shorts and short skirts, but stay in air-conditioned rooms. Long-term exposure of legs and knees to low temperature will invade our joints and affect the vasoconstriction of legs. After a long time, you will feel pain in your joints.

5. Irregular menstruation & dysmenorrhoea

In summer, the environment where the body is exposed to air conditioning will change and the body will be affected. Our female friends often blow air conditioning, especially before this physiological period or during menstruation. Long-term cold stimulation can easily affect ovarian function and cause irregular menstruation.

However, there is a big difference between the room temperature and the outdoor temperature in air-conditioned rooms. Suddenly going out and coming back from a low-temperature air-conditioned room will make the body feel that the temperature difference is too large and the peripheral blood vessels cannot contract quickly. In the long run, there will be dysmenorrhoea, which is what we often call dysmenorrhea.

In addition, there may be symptoms such as dry eyes, dizziness and headache, reminding you that you can't always covet the cool feeling brought by air conditioning. It's not that you can't blow the air conditioner in summer, but you should pay attention to this and don't get sick.

? Keep warm measures in place.

Many friends have to stay in air-conditioned rooms for a long time because of work. In this case, it is necessary to keep ankles, knees and belly buttons warm. You can bring a long-sleeved dress to the company, prepare two pairs of thin socks, or prepare a small blanket to cover your legs to keep warm. Keeping warm can reduce a series of problems caused to the body.

Increase air humidity

You can buy a humidifier online and put it in an air-conditioned room. Controlling the humidity at 40%-60% will make you feel more comfortable and relieve the problem of dry skin. Remember to drink plenty of water to moisten your throat, which can promote metabolism.

Clean the air conditioner regularly.

In fact, air conditioners will accumulate a lot of dust after being used for a period of time, especially the filter, which will not only affect your health, but also affect the service life of air conditioners. It is recommended to find a professional master to clean and disinfect the air conditioner regularly, replace the filter screen if necessary, and give it a "maintenance".

? Turn on the air conditioner to the right temperature.

Some people like low temperature to cool down, but the temperature difference between indoor and outdoor is too big, and the moment when people walk out of the air-conditioned room is really uncomfortable! So the temperature should be adjusted. Generally speaking, 26℃ is the most suitable temperature for human body. It is best to control the indoor and outdoor temperature difference not to exceed 7℃, so that it will not be greatly affected even if it goes in and out of the human body.

Also, don't blow the cold air of the air conditioner directly to the human body. Pay attention to adjust the tuyere. You'd better adjust your timing when you sleep at night. Stop blowing all night. After blowing the air conditioner for a long time, it is best to turn off the air conditioner or open the window to discharge indoor air and let in fresh outdoor air, which can keep the indoor air clean and is more conducive to human health.

Finally, I hope the steamed stuffed bun will not be lazy. Bed sheets, pillowcases and other bedding at home should be cleaned frequently. Exposing them to the sun can sterilize them. Clean and hygienic, so that sleeping will be more fragrant ~
