We should have a correct understanding of blood donation. In the past, our country didn't have enough blood reserves, because many people had some misunderstandings about blood donation at that time, thinking that blood donation would harm health. Then it caused the lack of blood bank resources in our country. At that time, there were still cases of spending money to buy blood. With the development of the times, everyone's awareness of blood donation has gradually improved. In fact, as long as you keep a proper amount of blood donation, it is good for your health, because human platelets can regenerate blood, and proper blood donation is beneficial to human metabolism. So everyone must have a correct understanding of blood donation. Under such circumstances, the blood resources of our national blood bank are also relatively rich.
Make relevant preparations before donating blood. You can't take medicine before donating blood, because some drugs will reduce some functions of platelets, so you can't take medicine three days before donating blood. Then eat normally the day before donating blood. It is best to eat some low-fat food, and at the same time, don't drink alcohol. You should also keep enough sleep. After donating blood, protect the blood donation site until the wound heals. Don't wet or rub the blood donation site within one day. You can't stay up late and you can't exercise.
Many people think that they need to replenish energy after donating blood, and then they will eat a lot. In fact, this is also a wrong supplement. Their nutrition is right, but they can't overdo it. You can eat some fresh vegetables or fruits, or you can eat some fatty foods, dairy products or beans. It is also good to eat some fish. Do not eat too much.
