Menstrual women are not recommended to donate blood. Menstruation is a regular physiological shedding of endometrium. During menstruation, the human body's resistance and immunity decline, and it will also affect the human endocrine system. Physiological ischemia can also be caused during menstruation.
Menstruation itself is a relatively weak period, and then blood donation is "deficiency plus deficiency." It will be even harder to recover in the future. Blood donation during menstrual period makes it difficult for blood cells to recover, which will further cause physical injury, fatigue and disease. Therefore, it is best to avoid blood donation during menstruation.
