Why do my shoulders feel sore when the fan blows on or gets a little cold?

Generally speaking, the occurrence of frozen shoulder is not only closely related to the lack of righteousness in old age, but also mainly because the shoulder is invaded by wind, cold and damp evil, such as living in wetlands for a long time, sleeping at night with shoulders exposed to block the wind, resulting in Wind, cold and dampness cause blockage of blood vessels and muscles. Therefore, special attention should be paid to avoiding wind chill and direct air-conditioning breeze in summer. Once symptoms are discovered, treatment should be carried out as soon as possible to alleviate the pain and inconvenience caused. What you need to pay attention to when using an electric fan: In the hot summer, it is very pleasant to turn on the fan and feel the cool breeze blowing on your face. However, many people get sick due to improper use of electric fans. The reason is that many people lack the common sense to use electric fans. Some people are too eager to cool down, placing the fan very close to the body and blowing it for a long time. In this way, the sweat on the side that is exposed to the wind evaporates quickly and the body surface temperature drops significantly. On the side that is not blown by the wind, the sweat evaporates slowly, the surface temperature is relatively high, and the blood vessels on the body surface are still in a state of relaxation, which ultimately leads to the body's Blood circulation is out of balance, and sweat excretion is also uneven. Symptoms such as headache, dizziness, and general discomfort may occur. In severe cases, it may even induce stroke. Some people suddenly use a fan to blow hard when their body is too hot and sweaty, which can easily cause a heat cold; if they blow a fan while sleeping, it can easily cause a cold. How to use a fan correctly? First of all, the wind speed should not be too high: Modern science believes that the indoor wind speed is best controlled at 0.2-0.5 meters/second, especially in rooms with good ventilation and in places with cross-ventilation. The wind speed of electric fans should not be exceeded. Too big. Secondly, it is not suitable to blow directly on people: blowing directly, wind evil can easily invade the body, especially when you are weak or sweating profusely, it is best to let the fan blow towards a corner; also, the fan should stop blowing and stop, and it is better to use a swing For children, the elderly, and people with weak bodies, it is better to use electric fans less to blow air, because "where evil is trapped, the Qi will be deficient." However, electric fans can be used to adjust the indoor airflow to indirectly cool down. Finally, be careful not to blow the wind while sitting or lying quietly when you sweat a lot, because at this time, the blood vessels on the surface of the whole body are dilated, and the sudden cold wind will often cause the blood vessels to constrict and stop perspiration immediately, thus causing internal damage to the body. Heat production and heat dissipation are out of balance, and excess heat cannot be excreted. In addition, after the cold wind blows, the local defense function decreases, viruses and bacteria invade, which can cause upper respiratory tract infection, muscle and joint pain, and some even abdominal pain and diarrhea. . In short, you must pay attention to the method when using an electric fan, otherwise a good thing will turn into a bad thing, which will be detrimental to your health.
