What are the advantages and disadvantages of donating blood?

Blood donation has become a public welfare activity that everyone participates in. It is the best choice for people to show their love. Walking on the street, you can often see slogans such as "Donate blood for free, everyone is responsible". So what are the benefits of blood donation? Will it cause harm to the human body?

What are the benefits of donating blood?

1. Donating blood not only shows love, but also stimulates the body's hematopoietic function, accelerates the production of red blood cells, and promotes blood metabolism in the body. Those who insist on donating blood regularly have much higher numbers of fresh blood cells than others, and the red blood cells they produce are younger and more energetic.

2. Donating blood can also delay the occurrence of some common diseases. After donating blood, the viscosity of the blood will decrease, and the blood flow rate will also increase. The energy of carrying oxygen and transporting nutrients will be enhanced. In this case, the blood vessels and blood will be in a healthy and normal state, and the probability of humans developing high-incidence diseases such as stroke, hypertension, and hyperlipidemia will also be significantly reduced.

3. When people donate blood, they are not only showing their love, but they can also get a chance for a free physical examination, which is one of the important benefits of donating blood. Because blood donation has certain requirements for human health, doctors will conduct a comprehensive health check on the blood donors, and if any problems are found, they can be treated in time.

4. In life, people who choose to donate blood for free can also give themselves, their immediate family members and spouse the opportunity to use blood for free, and within three years of their blood donation, they can enjoy three times the amount of blood they received. In other words, people who donate blood for free are storing a certain amount of blood for themselves, which can be used directly in the event of an emergency in the future.

Disadvantages of donating blood

Although donating blood is good for the human body, if you are physically weak and are forced to donate blood, you will experience symptoms such as being weak and sickly and having cold hands and feet. In addition, many people are prone to hunger after donating blood, and they will overeat and become obese, which is also a common disadvantage of donating blood.
