The weather is very hot recently. Do you know what to pay attention to when blowing air conditioning?

Recently, the weather is hot, and many diseases caused by air conditioning are increasing, especially for middle-aged and elderly people over 50 years old. A 70-year-old aunt couldn't walk because she caught cold and had severe pain in her knees after blowing air conditioning. There is also a 42-year-old man who came home from the outdoors covered in sweat, blew the air conditioner for more than ten minutes and had an acute myocardial infarction. These diseases caused by improper use of air conditioners are constantly happening around us. Although air conditioning is an essential survival artifact in hot summer, don't endanger the health of yourself or your family because of improper use. So when middle-aged and elderly friends use air conditioners, what wrong practices may affect their health? Who needs extra care? Today, I will summarize the following four points that are most easily overlooked.

First, don't blow the air conditioner directly at your body. The wind is very cold. When we come back from the hot outdoor, don't turn on the air conditioner and blow it directly at our bodies. Use the air conditioner as a fan. Although the weather is cool, sudden cold stimulation will cause rapid contraction of blood vessels and limb ischemia, especially in the elderly with fragile blood vessels, which may lead to serious cardiovascular and cerebrovascular accidents. You can raise the air outlet of the air conditioner, or cover it and blow it against the roof or the ground to reduce the indoor temperature.

Second, the temperature should not be too low. Many middle-aged and elderly people have low back pain, leg pain and joint pain. In summer, they wear thin clothes. Long-term cold stimulation of shoulders, knees, waist and legs is easy to induce pain, joint pain and muscle pain. It is easy to have abdominal pain and diarrhea after catching a cold. Therefore, the elderly must pay attention to the low temperature when turning on the air conditioner, but many elderly people live with young people, and young people are stronger.

Third, prevent colds. The air in the air-conditioned room is not circulating, and it is easy to catch a cold, such as coughing and wheezing, if you enter the air-conditioned room with lower temperature from the hot outdoor. Especially, middle-aged and elderly people are weak, and they may have some basic diseases, such as asthma and tracheitis, which are easy to be induced. Moreover, when sleeping, the air conditioning temperature is too low, muscle activity is less, body metabolism is slow, fever is less, and it is easier to catch a cold.

Fourth, the air conditioner should be cleaned before use. Recently, many people got pneumonia because of blowing air conditioners, especially the elderly who are weak. Air conditioners will absorb a lot of dust and microorganisms when they are not used for a long time. If they are inhaled into the lungs, they may cause allergies or pneumonia. Therefore, it is recommended that you clean the air conditioner before you start using it. If you can't clean it yourself, you can ask a professional worker to help you clean it.
