After running for 40 minutes, my back was sweaty, but my arms were cold and a little painful. Why?

After running for 40 minutes, my back was sweaty but my arms were cold. The reason why I feel a little cold and a little painful may be that my body is adjusting the temperature. When we exercise, our bodies generate heat and dissipate it by sweating. Sweating on the back may be because there are many sweat glands here and the heat dissipation effect is better. The cold arm with mild pain may be caused by insufficient blood supply.

During exercise, the body will give priority to supplying blood to the moving muscles to meet their needs. This has led to a relative decrease in blood supply to other parts. As one of the parts far away from the heart, the arm is likely to be affected by insufficient blood supply, thus feeling cold and painful.

Cold weapons may also be related to circulatory problems. When the body is exercising, the heart needs stronger contractility to promote blood flow. If there is a problem with heart function or poor vasoconstriction, it may lead to slow or poor blood flow, which will affect the arm.

In order to improve this situation, the following measures can be taken:

Strengthen exercise: gradually increase the intensity and time of exercise, improve heart function and vascular elasticity.

2. Uniform motion: After running, you can relax your arms and shoulders and promote blood circulation.

3. Keep warm: During exercise, especially in cold weather, keep your arms warm. You can choose long-sleeved sportswear or gloves.

4. Develop good living habits: a reasonable diet, adequate sleep, and reducing stress are all conducive to improving the function of the circulatory system.
