Why are my legs so cold?

There is a folk saying that aging starts from the legs, which shows that the legs have a special aspect in the human body's physiological functions. Some people are afraid of cold legs and always feel that their legs are cold from the inside out. For example, in summer, when the weather is extremely hot, they feel uncomfortable when they turn on the fan, let alone stay in an air-conditioned room. So, what is going on? Can I be completely cured if I see a doctor?

The knee joint is an important joint that supports human activities such as standing, walking, running, and jumping. It consists of the distal end of the femur, the patella, the meniscus, and the joint capsule at the upper end of the tibia. Some people's knee joints will be worn to varying degrees due to standing, running, and jumping for a long time; or due to excessive fatigue, cold, humidity, and other knee joint diseases, the knee joints will become afraid of cold.

To avoid this situation, you can take the following preventive measures:

1. Avoid moisture. After exercise, when your whole body becomes hot and sweaty, and your clothes and socks become wet, you should change them quickly, dry your body, and ensure that your body is in a good dry environment.

2. Clothes, shoes and socks should be soft and warm, and not too thin or too tight. Because being too thin will not be warm, and being too tight will affect systemic or local blood circulation, making the knee joint more sensitive to cold.

3. You can make a "knee belt" with cloth and cotton or animal fur such as rabbit hair, cat skin, etc. (the fur should face the knee joint). When you are active, you can change to "knee pads" (available at sporting goods stores) to protect yourself from the cold. However, "knee pads" are made of elastic bands. Long-term wearing will hinder blood circulation in the knees and affect the condition of the knee joints. Therefore, you should take them off in time after activities and replace them with "knee belts".

4. Before going to bed every night, soak your feet in hot water for 10 to 15 minutes, keeping the water temperature at around 40°C. This can not only eliminate fatigue but also promote sleep.

5. You can use cold water to scrub the front, back, left and right sides of the knee joint once in the morning and evening for 3-5 minutes each time. Then wipe it dry with a dry towel until it is slightly warm (do not break the skin) to improve the knee joint's ability to resist cold. This kind of local cold water bath is best started in the summer and continued into the autumn and winter. If you can persist in it all year round, the effect will be better.
