Donating blood is good for your health. If you are healthy, free from any diseases and full of energy, it is usually good for you to donate 200 ml of blood each time.
Blood itself is a circulation in the body, and the heart is like a pump, which pushes the blood forward, circulates all the way to the whole body, and then returns to the heart to continue the circulation. In this process, there will be some blood loss, but the loss will not be much, but the toxins in your body are increasing day by day, and there may be some toxins in your blood (which will not affect your health). If the blood is not updated, then these toxins are likely to remain. So if you choose to donate blood at this time, your blood will be reduced by a part (a small part).
Your hematopoietic stem cells will absorb the energy in your body and make blood until you are full. Your blood will also be purified to some extent. It will be more beneficial to your health.
Blood donation can speed up the circulation in your body, promote your metabolism and make your body stronger.
Moreover, the purpose of donating blood is to save other people's lives, which is a supreme merit.
Disadvantages of blood donation If you are in poor health, there may be some problems after blood donation, such as weak body and easy to get sick, or headache and brain fever. And many girls are prone to chills after donating blood.
Of course, most institutions will check whether you have any physical illness before you donate blood.
How to do it before and after blood donation? Before blood donation, you must pay attention to rest, energy and sleep. And the nutrition must be balanced, and you can't overeat or drink alcohol. These will affect your blood quality. And be sure to avoid big fish and big meat, which will cause your blood lipid to rise instantly, so try to keep a balanced nutrition before donating blood.
Pay more attention to rest after donating blood, because nearly 200 or 300CC of blood is drawn from your body, which is a great consumption of your physical strength, and your body organs will also strive to make blood, so you must pay attention to rest, but you must be careful not to overeat. Even if you feel hungry after donating blood, you should try to achieve a balanced nutrition and eat seven points full. And be sure to eat more vegetables and supplement protein and iron. And overeating also has a disadvantage that it is easy to get fat.
Therefore, under normal circumstances, blood donation is beneficial to physical and mental health, but we must do what we can and take care of our bodies first.
