First of all, applying a hot towel to the knee joint is the most important and simplest way to care for the legs. Before going to bed every night, you can soak your feet with a basin of water. At the same time, you can also use a hot towel to hot compress your legs. Especially in the knee joint, hot towels can promote the blood circulation of the legs, relieve the pain of the knee joint and relax the muscles.
Second, massage your legs a little every day. Massage the legs can promote blood circulation. Knee joints can be massaged clockwise every day. Be sure to master the strength when massaging, and don't use too much force. For example, acupoints such as Zusanli can be massaged every day, and each massage can last for ten minutes. Massage can also relax leg muscles.
Third, we can always see many old people in the square. They gently twist their knees in the square every day. Gently twisting the knee joint can promote the blood circulation of the knee joint in the leg and make the joint not stiff. When twisting the knee joint, you can do it according to your own preferences. Some people like to twist their knees clockwise, while others like to twist their knees counterclockwise. The action of twisting the knee requires the body to stand up straight, bend one leg, and gently lift it parallel to the ground. Many people will hear a click when they twist their knees for the first time, because they haven't twisted their knees for too long and make a normal sound.
