Five major parts of the body are prone to air-conditioning diseases

Lesser Heat and Greater Heat are the hottest periods in summer, and are also the most common times when people use air conditioning to cool down. Air conditioning is a good facility to prevent heatstroke and cool down. However, if you don't use it properly or use it for too long, you must be careful about getting air-conditioning disease. Today, we will discuss the causes of air-conditioning disease when using air conditioners, the parts of the human body most susceptible to air-conditioning disease, and how to prevent the occurrence of air-conditioning disease for your reference.

1. Causes of air-conditioning disease

First, the stimulation of excessive cold causes differences in human skin temperature. That is, the temperature of the limbs is lower than that of the trunk, the hands and feet cool down, and the body's ability to regulate temperature is powerless to do anything about this.

Second, when entering an air-conditioned room from the higher temperature outdoors or other houses, the temperature difference is large and the temperature changes suddenly. The human body's autonomic nervous system is difficult to adapt, and symptoms of air-conditioning disease will appear. Symptoms include irritability, tension, insomnia, etc.

Third, in an ultra-cold room with air conditioning, the negative ions are almost zero. Negative air ions are negatively charged air molecules that can invigorate people and improve human body functions. They are called the "vitamins" of the air. If there is a lack of negative ions, people will feel that the air is "stale" and feel chest tightness, palpitations, dizziness, weakness, and a significant decline in work efficiency and health. It has been determined that the number of negative ions per square centimeter in an ordinary room is fifty, but this can be reduced to less than ten after using an air conditioner.

2. Five parts of the human body that air conditioners love to attack

Part 1: The respiratory tract is the most "vulnerable"

The respiratory tract is the most vulnerable. Once the cold air breaks through the fragile "defense line" of the respiratory tract, mild symptoms of a cold such as coughing, sneezing, runny nose, etc., that is, upper respiratory tract diseases, will appear; experts say that the more serious lower respiratory tract disease caused by air conditioning is pneumonia. Experts point out that central air conditioning is very suitable for the spread of Legionella, especially when working and studying under it. The incubation period is about 2-12 days. Although there is no upper respiratory tract reaction, there will be fever, chills, muscle aches, dry cough, no sputum or little sputum. If not treated in time, fever, dry cough, chills will continue, and severe cases may even lead to death from respiratory failure.

Part 2: Brain nerves become unbalanced

I often hear people who often sit in air-conditioned rooms complain like “I feel dizzy, I see stars, and I tend to forget things.” It is reported that this is a common brain nerve imbalance reaction caused by air-conditioning disease. In addition to causing people to catch colds, air conditioning can also cause serious damage to the brain. The anions contained in the air can inhibit the human central nervous system and relieve brain fatigue.

However, the air conditioner absorbs too many anions, causing more and more cations in the house. The imbalance of anions and cations also causes the brain's nervous system to become disordered and unbalanced.

Part 3: Joints and stomach are susceptible to cold

Young people often don't pay much attention to the joint pain caused by air conditioning, but frequent use of air conditioning will cause various problems. In summer, the air outside is scorching hot and people generally wear less, but the air conditioning indoors is very strong and the clothes are so thin. Such a low temperature environment will stimulate blood vessels to contract sharply and blood circulation will be poor, leading to joint damage, cold, and pain. Common reactions include stiff neck and back, pain in the waist and limbs, and cold and numb hands and feet.

In addition, a house that is too "cold" can easily lead to weakened gastrointestinal motility. Coupled with the fact that people tend to stay cool in the summer and often drink cold drinks, the intestines are controlled by "cold" inside and outside, so it is no wonder that many people suffer from diarrhea and vomiting.

Part 4: Be careful with your neck so it doesn't get blown crooked

Staying in an air-conditioned environment for a long time and being blown by cold wind frequently will cause many people to have "crooked necks" and "hunched backs". Experts pointed out that white-collar workers work at their desks with their heads down for a long time or surf the Internet in one posture for a long time, which causes the cervical spine to be in a flexed position for a long time. In addition, when working in an office building, wearing little and suddenly exposed to cold, the joints can easily catch cold and be injured. Old problems in the cervical spine, shoulders, lumbar spine, etc. are more easily stimulated at this time. Therefore, once the air conditioner is turned on, if you do not pay attention to keeping the head, neck, shoulders, etc. warm, it is very easy to cause cervical, shoulder and lumbar diseases.

Part 5: Exposed skin allows eczema to "take advantage of the opportunity"

Many air conditioners have not been used for a long time, and a large amount of dust, mold, etc. have been absorbed on the filter. As the cold air from the air conditioner blows into the room, it attaches to human skin or is inhaled into the body. In addition, many indoor environments are closed and air is not circulated, which greatly increases the chance of inducing eczema. In addition, long-term cooling of the air conditioner will produce a large amount of condensation water, making the air drier and drier. However, we wear less clothes and most of our skin is exposed, which accelerates water loss and becomes another major cause of recurrence of eczema.

3. The air conditioning temperature needs to be “degree”

1. The difference between the air-conditioning temperature and the outdoor temperature should be within 5℃

According to tests, for people who are sitting still or doing light work, when the air conditioner is set at 26℃, the humidity in the room is around 50%, which is a more suitable humidity for the human body and makes the human body feel more comfortable. The most suitable air-conditioning temperature for the human body is also between 24℃ and 27℃. Considering energy saving, it is most appropriate to set it to 26-28℃ in the summer night. The temperature difference between indoor and outdoor should not be greater than 5℃. Too large temperature difference can easily cause air-conditioning disease. When the air conditioner is cooling, setting the temperature 2℃ higher can save 20% of electricity.

2. What is the most suitable temperature for the air conditioner when sleeping at night?

Under constant temperature, the room temperature maintained at 28 degrees is best for rest. Because when resting, the human body's immunity will decrease. If the room temperature is too low, you will experience symptoms such as fatigue, headache, back pain, limb pain, joint pain, etc. when you wake up the next day. In more serious cases, it can cause diarrhea, irregular menstruation, "air-conditioning disease" and more diseases. When people sleep, their metabolism decreases by 30-50%. The air conditioner should not be lower than 24℃ at night, or the air conditioner should be set to the sleep switch. Therefore, young friends should not turn on the air conditioner all night long when sleeping for the sake of coolness. At most, you can set it to night mode. As long as you can fall asleep coolly, it will be fine. Otherwise, it is easy to catch a cold after falling asleep.

Four, six methods to deal with air conditioning disease

Method 1: Pay attention to ventilation. When using air conditioning, you must pay attention to ventilation. It is recommended to open the windows regularly every day, turn off the air conditioner, let fresh air circulate, and clean the air conditioner body every two weeks.

Method 2: Drink more water for your body. When you go out from an air-conditioned environment, you should first move around in a cool place for a while, and then move around in the sun after your body has adapted. Drink more water, which can speed up the metabolism in the body.

Method 3: The temperature should not be set too low. The difference between the air-conditioned room temperature and the natural outdoor temperature should not be too large, preferably not exceeding 5 degrees. It is best not to use the air conditioner when sleeping at night. It is safer to turn off the air conditioner when going to sleep. Doing outdoor activities before going to bed will help promote blood circulation.

Method 4: Don’t blow directly under the air conditioner. When working or studying in an air-conditioned environment, do not let the cold air from the vents blow directly on your body. It is best not to blow cold air directly when you are sweating profusely, as this will cool you down too quickly and easily cause physical discomfort.

Method 5: Keep your skin clean and hygienic. Due to frequent entry and exit of air-conditioned environments and sudden changes in temperature, bacteria attached to the skin can easily become blocked in the sweat glands or sebaceous glands, causing infection and suppuration. Therefore, you should take a bath frequently to keep your skin clean.

Method 6: Don’t smoke in an air-conditioned room. Never smoke in an air-conditioned room to avoid the accumulation of carcinogens in the smoke, which may cause harm to the human body.
