How long can I keep fit after blood donation

how long can I keep fit after blood donation?

Because the human body absorbs oxygen through hemoglobin in red blood cells, and then transmits oxygen to muscles and other organs. The reduction of red blood cells after blood donation will make all parts and organs of the body unable to get enough oxygen, and various life functions of cells can not be normally played. For example, dizziness after blood donation is mainly due to insufficient oxygen in the brain.

Therefore, the level of aerobic exercise may be temporarily affected after blood donation. Blood donation will temporarily reduce the blood volume for about a day, and the oxygen carrying capacity will be reduced for about a few weeks. These changes can lead to reduced athletic performance. Until the red blood cells recover to the previous level, it is safe to avoid fitness, have a good rest, enhance nutrition and supplement more liquid ingredients appropriately within the first three days after blood donation. After three days, you can take part in some light fitness exercises, such as walking, cycling and so on.

If there is no obvious discomfort, you can gradually increase the amount of exercise, such as fast walking, jogging and so on. Generally, the number of white blood cells and platelets in the human body will return to the original level within about a week after blood donation, and the albumin, inorganic ions and immunoglobulins in the plasma will also return to the level before blood donation. However, the recovery time of red blood cells is longer, sometimes it takes about three months. So mild blood donation has no obvious effect on the human body, but try to take part in fitness activities after a week.
