When Qi and blood deficiency occurs, the decision to exercise or rest should be based on the cause of Qi and blood deficiency. If the Qi and blood deficiency is caused by weakness of the spleen and stomach, uneven diet, etc., it can be improved by more exercise, but if more rest will aggravate the Qi and blood deficiency. If the lack of qi and blood is caused by excessive blood loss, overwork, etc., you should rest more, and more exercise in this case may aggravate blood loss or fatigue, etc., which is not conducive to physical recovery. More exercise can fundamentally enhance physical fitness and change the state of Qi and blood deficiency caused in part by physical weakness. Strong limbs and bones can enhance liver, kidney and spleen functions. Common exercises include mountain climbing, pull-ups, etc. Aerobic exercises such as swimming, rope skipping and jogging can exercise the heart and lung function and improve the upper limit of qi and blood, so proper exercise can improve the state of qi and blood deficiency. However, we should pay attention to gradual and orderly progress, do not suddenly or blindly a large number of, strenuous exercise, in order to avoid damage to the body. More rest is mainly applicable to Qi and blood deficiency caused by the loss of blood from the body. If the amount of blood loss is too much and already seriously affects daily life and action, more exercise may aggravate the blood loss, at this time it is recommended to rest more. Due to excessive exertion caused by insufficient qi and blood, doctors will also generally recommend appropriate rest, but this rest mainly refers to avoid staying up late, excessive worry, etc., and does not mean complete bed rest. However, for some people who are suitable for more rest, it is also recommended to exercise properly after the symptoms are improved and the body can tolerate it. More exercise is not strenuous, but conducive to strengthening the muscles and bones, and to enhance the internal organs and blood flow, as well as to regulate the balance of the body’s yin and Yang.
