Side effects after female blood donation

The human body's blood is constantly metabolizing. Normally, red blood cells need to be replaced every 4 months. Donating blood will stimulate the hematopoietic function of the bone marrow, promote metabolism, increase new blood cells, and enhance various physiological indicators. There are side effects after girls donate blood, therefore, donating blood is good for health. Regular blood donation may also protect against heart disease, which is primarily related to the loss of stored iron in donors. A mild iron deficiency can reduce the risk of heart disease, while an excess of iron in the body can increase the risk of heart disease.

1. Donating blood has good long-term effects on the cardiovascular and cerebrovascular systems: it can prevent and alleviate blood viscosity, and reduce the occurrence of cardiovascular and cerebrovascular diseases. Due to the improvement of living standards and the reduction of physical activity, people accumulate more and more fat in their bodies and it remains at a high level for a long time, commonly known as "thick blood". The result of "thick blood" is that fat attaches to the blood vessel walls layer by layer, eventually forming arteriosclerosis, reducing blood vessel elasticity, and leading to cardiovascular and cerebrovascular diseases. Regular blood donation reduces the amount of viscous blood in the body, and normal drinking of water replenishes the blood volume, which naturally dilutes the blood, and blood lipids will decrease. Donating blood in moderation can reduce all components in the blood, with the largest reductions being blood iron and protein. It also reduces blood viscosity and speeds up blood flow. With increased oxygen supply, people feel relaxed and clear-headed. It can effectively reduce arteriosclerosis, thrombosis, cerebrovascular accidents, myocardial infarction and other diseases.

2. Regular blood donation can improve hematopoietic function: because after the fetus is born, the bone marrow becomes the main hematopoietic organ. As age increases, hematopoietic function and blood cell production rate gradually decline. After donating blood, the number of blood cells decreases, which stimulates the bone marrow, prompting the release of mature blood cells stored in the bone marrow, and stimulates the bone marrow hematopoietic tissue to promote the production of blood cells. Regularly donating blood within the prescribed period can keep the bone marrow vigorous.

3. Men donating blood may reduce the incidence of cancer: if the iron content in the body is too low, it is easy to suffer from iron deficiency anemia and slow movement, while if the iron content is too high, it will have the opposite effect. "International Cancer" once reported that if the iron content in the body exceeds 10% of the normal value, the chance of developing cancer increases (because the red blood cells in the blood contain a large amount of iron), and donating blood in moderation can prevent cancer - this statement currently lacks evidence and has not been internationally recognized.

4. Can promote and improve mental health: A large number of studies have shown that healthy emotions can communicate with the brain and other tissues and organs through the nervous, body fluid, and endocrine systems, keeping them in a good state, which is beneficial to enhancing the body's immunity and resistance. Donating blood is a noble act that saves lives. While helping others and being kind to others, it also purifies one's spirit, comforts one's soul, and makes work and life more fulfilling. Those who do good deeds are doing good with virtue, and in fact they are helping themselves while helping others, which is an important factor for health and longevity.
