Why is it easy to get rheumatoid arthritis when the weather is cold?

It is true that personal feelings are related to the cold weather.

The main reason is that the cold circulation is not good, and I don't feel anything at ordinary times, but I feel obvious when I am cold.

In fact, the cause of rheumatoid arthritis is not very clear. At present, most people think that it is an autoimmune disease of human body, and it can also be regarded as a chronic syndrome, which is characterized by nonspecific inflammation of peripheral joints.
