But it has been circulating in the market that bare ankles belong to? Beauty, not health The practice will make the body in trouble, and WeChat articles also advocate this statement.

But in fact, there are many mistakes in the content in the screenshot above.
Blood is different from skin and muscle. Blood is circulating, always flowing. A local cold does cause vasoconstriction, but? Will there be more blood in the joints? There is no basis; To say the least, it doesn't matter if it's worse, it will flow away anyway.
Of course, our point of view is, is it really related to the disease?

Rheumatoid arthritis (RA) is a systemic autoimmune disease. In other words, there is something wrong with the patient's immune system. He doesn't regard his own organization as his own, but attacks it at will. It makes the synovium of the joint hyperemia and edema, then, the synovium edge proliferates, forming granulation tissue, covering the articular cartilage surface, and finally, granulation tissue fibrosis. Clinically, just like osteoarthritis, there will be symptoms such as pain, swelling and fricative sound; However, what is osteoarthritis? What's wrong with it? Rheumatoid joints are characterized by bilateral and multi-joint involvement at the same time, and different degrees of deformity can occur in the late stage.

The cause of rheumatoid arthritis is still unknown. From 65438 to 0939, some scholars detected a special antibody from patients with rheumatoid arthritis, which was later named as rheumatoid factor (RF). [5] Thus, the hypothesis of rheumatoid factor was born, which believed that rheumatoid factor would interfere with the normal immune system, thus causing rheumatoid arthritis. However, recent research shows that many normal people have rheumatoid factors, so scholars have revised this theory: heredity determines whether people will carry rheumatoid factors, and microbial infection, hormone level (which can explain why female rheumatoid arthritis is more frequent) and eating habits may be risk factors for activating rheumatoid factors. [4]
Well, we have summarized the causes of various rheumatism and arthritis, and we can see that it has nothing to do with cold.
Previous large-scale surveys have also confirmed this. In 2005, a survey involving six administrative districts in China showed that osteoarthritis was closely related to age, drinking and occupation. There is no linear relationship with latitude and longitude (temperature); [5] In 2000, a survey in a third-class first-class hospital in Hefei showed that there was no statistical significance between the living terrain (mountain or plain, with temperature difference) and the prevalence of rheumatoid arthritis. [6]
The weather is not a problem, and showing your ankles is naturally not a problem. But for arthritis patients, there is often a change in air pressure before the weather changes, and the change in air pressure will affect the joint pressure. Therefore, arthritis patients seem to bring their own weather forecast.
In addition, it's okay to show your ankles, but you must choose your shoes. Too small, too high, and too peaceful can all cause joint damage, and then develop into osteoarthritis.
Truth: A cold caused by bare ankles will not cause rheumatism or arthritis.
