6+ Health Benefits of Donating Blood That are A Pity To Miss

Blood is one of the most important components in the human body. Your decision to donate blood through blood donors can save one life, or even several lives at once. Not only beneficial for the recipient, as a donor, you can also get the health benefits of donating blood for your own health. Anything? Check out the review below.

What are the health benefits of donating blood?

Blood donation allows you to give a small amount of blood in the body. Usually, as much as 480 milliliters of blood is taken.

Men can donate blood every 12 weeks (3 months) and women can donate blood every 16 weeks (four months)—a maximum of 5 times in 2 years—because men usually have more iron stores than women.

Later, the blood you donate will be checked and tested for safety and grouped by blood group. This is useful so that the blood given is truly in accordance with the patient’s needs and is ensured to be safe from possible diseases that appear in the blood.

Some conditions that require blood donation, including:

In addition to patients, there are several health benefits of donating blood, namely:

1. Lowers the risk of heart and blood vessel disease

Regular blood donation is known to be beneficial for lowering blood viscosity. The thicker the blood that flows in the body, the higher the possibility of friction between blood and blood vessels.

The friction that occurs in these blood vessels can damage blood vessel wall cells, which can further increase the risk of blood vessel blockage. This condition increases your risk of experiencing heart disease.

According to American Journal of Epidemiology, blood donation activities can reduce the risk of heart disease by 33% and heart attack by 88%. The American Medical Association says that donating blood every 6 months can reduce the risk of heart attack and stroke at the age of 43-61 years.

This is because blood donation also helps the body to get rid of excess iron. Excessive iron in the blood can cause oxidation of cholesterol. The results of the oxidation process can accumulate on artery walls and increase the risk of heart attack and stroke.

Through blood donation, iron levels in the body can become more stable and reduce the risk of heart and blood vessel disease.

Lower blood pressure

Research shows that people who donate blood experience a gradual drop in blood pressure. Normal blood pressure will prevent you from having heart attacks and strokes.

2. Lowers the risk of cancer

The next benefit of blood donation is to prevent cancer. This is also still related to the amount of iron that is reduced when donating.

According to research published in Journal of the National Cancer Institute, excess iron can cause free radical damage that puts you at risk for cancer and aging.

3. Help lose weight

According to the University of California San Diego, donating 450 milliliters of blood can actually burn as much as 650 calories. That’s why, blood donation is also useful for maintaining ideal body weight and keeping you from obesity risk.

Even so, do not make blood donation as an ‘event’ to lose weight. Excessive blood donation can be harmful to your health.

4. Detect serious illness

Every time you want to donate blood, you will undergo routine basic checks, such as checking your weight, body temperature, pulse, blood pressure, and hemoglobin levels.

You will also be asked to undergo a blood test to detect the presence or absence of infectious diseases, such as: HIV, hepatitis B, hepatitis C, syphilis, and malaria. It aims to prevent the occurrence of disease transmission through transfusion.

For donors, this examination is of course useful for early detection of certain diseases. So in addition to helping others who need blood, you can also get free health checks.

5. Encourages Blood Cell Production

By donating blood regularly, your spinal cord will produce new red blood cells to replace the donated blood. That way, the production of blood cells will increase and cause blood flow to become smooth.

6. Helps to be psychologically healthier and live longer

A study in the field of psychology shows that people who donate blood with the aim of helping others have a lower risk of death. These results are compared with those who donate blood for their own sake or don’t donate blood at all.

Another important benefit of blood donation is the fact that donating something priceless to the needy will make us feel psychologically satisfied.
