[Enough science] Air conditioning can also be the source of disease, so beware of ＂air conditioning disease＂

In the scorching sun, people like to enjoy the coolness brought by air conditioning in the office, but some people will have dizziness, shoulder and neck pain and other symptoms when blowing air conditioning for a long time, which is called "air conditioning disease".

"Air-conditioning disease" occurs mostly in summer, and the elderly, children and women are prone to it. Xiong Yan, deputy head of the Youth Study Group of the Sports Medical Branch of the Chinese Medical Association and associate professor of west china hospital, said that there are three main reasons for the "air conditioning disease": First, long-term work at the desk leads to continuous tension in the neck and shoulder muscles, and over time, there will be chronic strain and fibrosis of the neck and shoulder muscles; Second, being stimulated by cold air of air conditioner is easy to cause spasm of neck and shoulder muscles and blood vessels, which in turn leads to tissue ischemia and hypoxia, causing pain; Third, the air in the relatively closed air-conditioned room is dry and turbid, and the dust spreads, which is easy to breed microorganisms and lead to the decline of the body’s resistance.

What are the tips to prevent shoulder and neck pain in the office? Xiong Yan said, first of all, you should keep a correct sitting posture: sit up straight, use cushions to support your back, look straight ahead with your eyes, your shoulders and upper arms naturally droop, your elbows are close to your torso, your forearms are at 90 degrees to your body, your thighs are flat, your knees naturally bend at 90 degrees, and your feet are flat on the ground. At the same time, hot water bottles can be used for local hot compress to promote blood circulation of neck and shoulder, relax muscle groups and relieve the symptoms of neck and shoulder muscle pain.

It can perform the greatest stretching in sitting posture, improve the mobility of cervical and thoracic vertebrae and reduce the degree of muscle stiffness. Fourth, carry out functional training. Remodeling the habitual position of joints and changing posture can keep the posture of head up and fundamentally reduce the occurrence of cervical pain.
