Three days of volcano will come, representing the highest temperature of the year and humid, hot days will come. The temperature is climbing higher and higher, so how can you stand it without air conditioning? The troubling thing is that, although the air-conditioned room is comfortable, but the family of the elderly always chatter, “always blowing air conditioning, it is easy to get arthritis in the future, ah, hurry off!” In the end, to blow, or not to blow? Today we will run through the summer air conditioning is really easy to get arthritis? People who think that blowing air conditioners in summer can cause knee problems think that staying in a cold environment for a long time will increase the risk of knee arthritis. To know whether this idea is reliable or not, we must first understand how knee arthritis is actually caused. What exactly is knee osteoarthritis? Joint pain is often the most common reason for patients to visit the doctor. There are many etiologies behind the onset of the disease, including osteoarthritis, traumatic arthritis, rheumatoid arthritis, and gout. The most common clinical causes are osteoarthritis of the knee and rheumatoid arthritis, and patients often confuse the two. Osteoarthritis of the knee is a degenerative disease, usually caused by obesity, family factors, age, joint trauma and other reasons that lead to increased wear and tear of the cartilage and a series of clinical symptoms. Rheumatoid arthritis of the knee is an autoimmune disease that is caused by lesions and inflammation of the synovial membrane, resulting in joint effusion in the joint, causing joint swelling and pain. What I want to tell you is that the occurrence of knee arthritis is generally related to the natural degeneration of the body’s functions and problems with the autoimmune system, and that there is no direct causal relationship between cold and the development of arthritis. Therefore, blowing on the air conditioner does not directly cause arthritis, so you can rest assured! What’s wrong with knee pain when you blow on the air conditioner? We need to know that cold does not cause arthritis, but it can be a trigger for arthritis-related symptoms! For those who already have knee arthritis, an overly wet and cold environment may make the symptoms of arthritis worse. So, when you feel that your knees often feel cold, chilly and windy, it is possible that you have problems within your knee joints and should visit a hospital as soon as possible to clarify. We would also like to remind patients that it is not only important to keep the joint area warm when blowing on the air conditioner, but it is also best to protect the joint area in cold and wet environments during the week. For most people with healthy joints, especially the younger age group, there is no need to worry about arthritis caused by air conditioning. However, it is important to remind everyone that although the weather is hot, it is still important to control the temperature in the air conditioning room and pay attention to ventilation so that the temperature difference between indoor and outdoor does not cause colds and heat stroke.
