My knees are particularly cold and painful. What's going on here?

When the knee joint is cold, the blood vessels will contract, the blood circulation will become worse, and the pain will increase. So be sure to keep warm when the weather is cold. Arthritis patients should pay more attention to keep warm in winter. It is very important to keep joints and adjacent muscles and ligaments warm. It is suggested that patients with arthritis wear gloves, scarves, warm boots and trousers, and appropriately increase warm "equipment" such as leg protection and waist protection to protect skin and joints from outdoor low temperature. But the knee pads should not be too tight, otherwise it will hinder local blood circulation and aggravate the condition.

In winter, people like to stay in warm rooms and seldom go out. However, maintaining daily activities can help joints maintain flexibility and normal function. The reduction of outdoor activities in winter will lead to the reduction of people's range and amount of activities, which is not conducive to joint health. Moreover, reducing activity can also lead to weight gain and joint compression. If it is too cold outside, you can choose to do proper aerobic exercise indoors. Using a treadmill or exercise bike is an effective way to keep body temperature and exercise joints. In addition, swimming in the indoor heated swimming pool is also a good exercise.

Eating more vitamin E and foods containing B vitamins can dilate peripheral blood vessels. Eat more isothermal foods such as nuts and carrots instead of cold foods. Eating spicy food, such as pepper, pepper and mustard, can promote blood circulation.

Hot compress can dilate blood vessels, improve local blood circulation, relieve muscle spasm and nerve relaxation, and improve tendon softness. Wet and hot compress are recommended. Wet hot compress is to soak the towel in a hot water basin, take it out and wring it out until it is half dry, and apply it to your knees. Can be covered with a cotton pad to prevent heat loss. Change it every 5 minutes and apply it for 20-30 minutes. Apply it 1-3 times a day. Soaking feet with hot water can prevent osteoarthritis. In the cold and humid season, it is best to soak your feet with hot water after coming home from outside, which can improve your immunity and prevent rheumatic diseases caused by humid environment. The hot water level of soaking feet should be about 20 minutes above ankle joint, which can promote blood circulation of lower limbs.
