When starting to exercise, the body will heat up, the heart will beat faster, the breathing will be quick. These reactions will go hand in hand with faster blood circulation in the body.
During exercise, the capillaries will dilate, allowing blood to flow 20 times faster than normal. As blood rushes to the muscles, the body begins to convert glucose into energy. This process will require a lot of oxygen.
In particular, the demand for oxygen is even higher when exercising. Therefore, it is not uncommon for the body to be deprived of oxygen. Because the hands and feet are farthest from the heart, the first signs of hypoxia will appear at these locations, manifested as a tingling sensation in the hands and feet.
This tingling or numbness is also related to poor blood circulation due to working in cold weather, smoking, vitamin deficiency.
Another reason why feet become numb during exercise can also be due to wearing inappropriate shoes. If the shoe is too tight, it can put pressure on the nerve in the foot, resulting in numbness and tingling.
When this pressure is removed, the tingling sensation is gone. Therefore, the immediate solution is to loosen the shoelaces, then find the right shoes. When choosing shoes, everyone should note that when exercising, the feet will temporarily swell a bit. Based on this factor with the thickness of the socks, the practitioner should choose shoes that are slightly wider than the foot size.
In addition, some diseases that also cause feet to itch during exercise, such as diabetes complications, multiple sclerosis or other nerve-damaging diseases, can also cause feet to become numb and itchy.
If the practitioner is worried about the numbness and tingling of the feet when exercising, do not hesitate to see a doctor.
