Why do my hands feel numb after exercise

Many friends will experience adverse reactions such as numbness in the hands and feet after exercise. This situation is most likely caused by long-term inactivity and the body is not adapted to exercise. Increasing the frequency of exercise can alleviate this situation. It may also be because the amount of exercise is too much and the body cannot adapt to it in a short time, so we should proceed step by step when exercising. Let’s analyze the reasons for numbness in the hands when running in detail.

1. Why do my hands feel numb when I run?

If your hands feel numb when running, it has something to do with blood circulation. When you run, most of the blood flows to the parts of your body where you exert force, especially your legs. This causes insufficient blood supply to the hands, leading to numbness. More exercise should eliminate this phenomenon.

When the human body is not supplied with Qi and blood, it will first feel numbness at the ends of the limbs. If the Qi and blood are seriously deficient, the numbness will increase centripetally. First of all, your physical strength may not be very strong. In addition, you do not have a good diet. In this case, you consume a lot of physical strength. Of course, your current situation will occur.

2. Numbness in hands while running

The numbness during running did not first appear in the legs, where the muscles contracted the most, but in the arms, suggesting that the numbness may not just be muscle fatigue. In fact, the feeling of muscle numbness is often a manifestation of nerve irritation and fatigue.

An obvious characteristic of nervous fatigue is that it affects the whole body, not just the part that is moved. Because nervous fatigue is often central fatigue, the reaction of the central nervous system (mainly the brain) will be transmitted to all parts of the body. This is why when you run with your legs, your arms will feel numb.

Sports fatigue experts believe that fatigue is caused by the accumulation of certain metabolites in body tissues. Lactic acid is a very important metabolite related to fatigue.

Lactic acid is an intermediate product produced during the metabolism of glucose in the body during exercise. Judging from the characteristics of running movements, although the arm muscles generate less strength and energy metabolism, and produce less lactic acid themselves, the lactic acid in the body's blood circulation, that is, blood lactate, can cause irritation to the arms.
