There are approximately 5-6 liters of blood in the human body (8% of body weight), and millions of its cells die every day and are replaced by new blood cells. The life cycle of an erythrocyte lasts 120 days, and then it is "reutilized" so that iron from hemoglobin is not lost.
Donating 450 ml of blood adds work to our body, but is not a big burden on it. On the contrary, it is an opportunity to spend calories lying in a chair!
The total volume of blood is restored almost instantly - in a few minutes. Plasma components are restored the fastest - within 24 hours. Erythrocytes return to normal in 4-6 weeks, and the level of hemoglobin - in 6-12 weeks.
Men can donate whole blood no more than 5 times a year, women - no more than 4 times a year. This is the average optimal number of times for the body to restore the level of red blood cells and hemoglobin. Women irreversibly lose a certain amount of hemoglobin during each menstrual cycle.
A person who has donated blood in no way feels that something is "restoring" in his blood or that something is missing.
But every donor can help the body recover by simple actions:
☛ drink enough water;
☛ eat a varied and nutritious diet;
☛ add more iron-rich foods to your diet: liver, cereals, spinach, etc.;
☛ Foods rich in vitamin C help the absorption of iron, so add tomatoes, sauerkraut, peppers, etc. to your meals.
The main thing to remember is that your blood saves lives!
