Recently, there has been a significant increase in the number of patients experiencing physical discomfort due to air conditioning in outpatient and emergency departments of some major hospitals in Beijing.

Yi Fan, a medical teacher, deputy director of the Department of Cardiology of Beijing Chaoyang Hospital affiliated to Capital Medical University, said: If you stay in this air-conditioned environment for a long time, some people will have dizziness, headache, fatigue, and lethargy. Some people will have this kind of loss of appetite, nausea, vomiting, and respiratory symptoms, including dry mouth, dry throat, and sore throat. Some patients will even have cough, Allergic rhinitis symptoms. For patients with cardiovascular diseases, if the temperature difference between indoor and outdoor is too large, it can cause the contraction of our blood vessels, leading to an increase in blood pressure. This can cause angina, even myocardial infarction, and stroke.

Some patients suffer from muscle soreness, Joint stiffness, and Fasciitis because they have stayed under the air conditioner for a long time, and the elderly with arthritis will also suffer from increased pain.

Du Xinru, Chief physician of orthopaedics department of Beijing Chaoyang Hospital affiliated to Capital Medical University, said that if the cold wind stimulation of long-term air conditioning causes muscle spasm, as well as the vasomotor dysfunction of our blood vessels, local metabolic disorder will occur, which will induce symptoms. For example, gout, which is originally a disease with increased uric acid, can easily form gout stones under cold stimulation, leading to acute inflammation and gout attacks.

How to use air conditioning scientifically while enjoying coolness without harming the body?

How can we use air conditioning scientifically during the scorching summer heat of this year, which lasts for 40 days, in order to enjoy the coolness while avoiding the occurrence of "air conditioning diseases"?

Du Xinru, Chief physician of the Department of Orthopaedics of Beijing Chaoyang Hospital affiliated to Capital Medical University: When we sleep, many people blow air conditioners to cover quilts. In fact, this is a way in itself. Different people have different parts that are afraid of cold. For example, if someone has joint pain, they should cover their joints.

Moist air can limit the evaporation of sweat in the human body, making the body temperature higher and feeling hotter. The dehumidification function of air conditioning can make indoor air drier and sweat on the body surface evaporate better, thereby reducing body temperature; If you leave the room for no more than 1 hour, it is best not to turn off the air conditioning, as it consumes the most electricity when the air conditioning is activated. Before leaving, you can increase the temperature by 1 to 2 degrees Celsius, which saves electricity and keeps you cool; Clean the air conditioner 2-3 times a year. It is recommended to clean the air conditioner once before, during, and when it is no longer in use in the summer.

Moderate outdoor activities can be carried out in summer to maintain metabolic balance

In addition, the doctor also suggests that one should not stay in an air-conditioned room for a long time due to the hot weather. In summer, it is also necessary to engage in moderate outdoor activities and sweat, which is beneficial for maintaining metabolic balance.

Du Xinru, Chief physician of the Department of Orthopaedics of Beijing Chaoyang Hospital affiliated to Capital Medical University: Even in hot days, you should take time to exercise outdoors for a while, and then let the body fully have a metabolic process. In fact, sweating itself is a process of releasing energy. At the same time, after our own activities, we can also let some muscles that have cramped joints in the air-conditioned room stretch out to achieve a metabolic balance.

The doctor reminds that if Joint stiffness, body aches and other symptoms occur due to air conditioning, it is generally not necessary to take medicine, and you can relieve the symptoms by wiping with a hot towel or soaking in hot water.
