These people who stay in the hospital are all due to air conditioning!

1. Sweating heavily on the air conditioning, causing myocardial infarction

According to the Qianjiang Evening News, recently, 69 year old Ms. Liu came home from the square dance with a sweat on her head. She blew the air conditioner for several minutes before feeling much more comfortable. She kept the air conditioner on all night as usual when sleeping at night. However, at about 1 a.m., Ms. Liu suddenly felt chest tightness and discomfort, accompanied by pain under the xiphoid process, and her symptoms could not be alleviated. She was urgently sent to the Second Affiliated Hospital of Zhejiang Chinese Medical University (Zhejiang Xinhua Hospital) for medical treatment. The examination result was initially considered as "acute non ST segment elevation myocardial infarction".

2. Failure to clean the air conditioner may result in Legionella infection

Last month, a man in Changsha, Hunan Province, who had not driven a car for two months, suddenly developed symptoms such as high fever and difficulty breathing. He was rushed to the ICU and diagnosed with Legionella infection. Recently, some people were sent to the intensive care unit due to extreme discomfort after blowing air conditioning at home, and were later diagnosed with "Legionella pneumonia".

Zhang Xiaohong, a doctor from the Emergency Department of Sichuan Provincial People's Hospital, said in an article published on the official account of Chengdu Business Daily's Sichuan famous doctor WeChat that the peak period of Legionella infection is from June to October every year, especially August, or it is related to the use of air conditioners that have not been cleaned for a long time. During the process of air conditioning, Legionella spreads into the air in the form of aerosols, which are inhaled in large quantities by immune compromised individuals. After a latent period of 1-10 days, the collective onset of the disease occurred.

3. Blowing air conditioning at too low a temperature can trigger asthma

Sun Yilan, Chief physician of the Department of Respiratory and Critical Care Medicine of Zhejiang People's Hospital, explained that Xiao Chen's acute attack of asthma was related to the respiratory tract infection caused by staying up late and turning on the air conditioner; The second possibility is that prolonged use of air conditioning can easily breed dust mites and trigger allergic asthma attacks.

4. Long term air conditioning can induce gout

Du Xinru, the Chief physician of orthopaedics department of Beijing Chaoyang Hospital, said in an interview with CCTV Finance that if the air conditioner is blown for a long time, this cold wind stimulation will cause muscle spasm and vasomotor dysfunction, and local metabolic disorder will easily occur, inducing symptoms. For example, gout is originally a disease with increased uric acid, which can easily form gout stones under cold stimulation, induce acute inflammation, and lead to gout attacks.

Blow the air conditioning on a dog day, be careful not to harm yourself at 10 o'clock!

How to use air conditioning scientifically in the scorching summer, in order to enjoy the coolness while avoiding the occurrence of "air conditioning disease"?

(1)Clean before using the air conditioner. Central air conditioning should undergo regular testing and use professional disinfectants to prevent respiratory infections caused by accumulated bacteria and mites in the air conditioning.

Home desktop air conditioners can also be cleaned by yourself:

Cleaning the filter screen:Unplug the power supply, open the outer cover of the air conditioner, remove the filter screen, and clean it under running water;

Clean the air conditioning heat sink:Select the air conditioner cleaner with "National Ministry of Health Disinfection Product Certificate No.", spray the radiator with air conditioner cleaner foam, and let it stand for about 15 minutes. After installing the filter screen, run it for about 15~30 minutes according to the normal refrigeration procedure.

Alcohol is not recommended for cleaning air conditioning!Although medical alcohol can be disinfected and sterilized, it also evaporates quickly and easily forms flammable and explosive gases. If it does not evaporate completely, turning on the air conditioner can easily be ignited by the starting current and cause an explosion!

(2)It is recommended not to turn on the air conditioning immediately when entering indoors from outside in summerAvoid rapid constriction of blood vessels, which can cause cardiovascular and cerebrovascular accidents.

(3)Do not close the doors and windows temporarily when turning on the air conditioningAllow the air to flow for a period of time before closing the doors and windows. When using central air conditioning, the fresh air rate should be increased and a certain amount of air circulation and natural ventilation should be maintained.

(5)Avoid direct blowing of cold air from air conditioningIf it is impossible to change the air conditioning outlet, you can buy an air conditioning windshield;

(6)Do not use the air conditioner for too longIt is generally recommended to open for 3 hours and close for a period of time, and open doors and windows for ventilation.

(7)When sleeping at night, you can set the air conditioner to Light-on-dark color scheme or turn it off regularly. The dehumidification function of air conditioning can make indoor air drier and sweat on the body surface evaporate better, thereby reducing body temperature.

(8) Staying in an air-conditioned room for a long time shouldAvoid getting cold in the joints, neck, waist and abdomen.

(9) Personnel who work and live in air-conditioned rooms for a long time shouldPay attention to increasing outdoor activities.

(10)Clean the air conditioning 2-3 times a year.
