However, it is not advisable to do strenuous exercise, and do some sports suitable for the elderly, such as playing Tai Ji Chuan, dancing in square dance, and doing broadcast gymnastics.

Second, keep warm, go out as little as possible in rainy days, and don't wear wet clothes. Pay attention to the warmth of joints, and you can wear a pair of elastic knee pads at home to prevent joints from being exposed. Avoid going out in rainy days, change clothes frequently when sweating, and keep clothes dry and not wet. Now it's getting colder and colder in the north, so it's best to bring a pair of warm gloves when going out in winter.
