Donating blood at regular intervals has been linked to a lower risk of heart disease because of several factors. Let’s understand these factors:
1. Reduces Blood Viscosity
Blood donation lessens the number of red blood cells thus leading to reduced blood viscosity. A higher blood viscosity obstructs your flow of blood. This can lead to high blood pressure and a higher workload on your heart. Donating a pint of blood (close to 500 mL) can approximately remove 200-250 mg of haem iron from your body.
This loss of iron may reduce the oxidative stress and blood viscosity. This can reduce the thickness of blood and thus, reduce the risk of heart disease in the long run and promote better cardiovascular health.
2. Helps alleviate Iron Overload
Iron overload can increase the oxidative stress in the body and may result in developing atherosclerosis which is a major cause of heart disease. Regular blood donation helps alleviate iron overload and consequently decreases the risk of developing heart disease.
3. May Improve Lipid Parameters
Donating blood at regular intervals can improve your lipid parameters. Regular blood donation may lower iron overload, and this in turn lowers lipid peroxidation. It has also been witnessed that regular blood donors have reduced total cholesterol, LDL cholesterol, and triglyceride levels. All these parameters are linked to a higher risk of developing heart disease.
Why does Blood Donation Make a Difference?
Donating blood has an array of benefits to the donor, including a reduced risk of heart disease. When you donate blood, your body encourages the production of active blood cells to replace the donated volume. This entire process stimulates blood circulation and stops the build-up of old and impaired red blood cells which are known to increase the risk of cardiovascular disease.
Hence, being a regular donor may help promote uninterrupted blood flow, reduce arterial blockages, and reduce the risk of developing heart disease.
Frequently Asked Questions
What are the benefits of donating blood to the heart?
Donating blood regularly may help reduce the risk of cardiovascular disease by depleting the iron overload in the body. It can also stimulate the production of newer blood cells which replace the aging and impaired red blood cells from the body. This helps reduce arterial blockages and encourages smooth blood circulation diminishing the risk of developing heart disease.
Why do I feel so good after blood donation?
When you donate blood, your body starts to replenish the lost blood volume within 48 hours of the donation. All the lost red blood cells are completely replenished within four to eight weeks after the donation. This entire process of replacement helps your body to stay active and makes you feel energetic and efficient.
Can donating blood reduce cholesterol?
Studies suggest that donating blood at regular intervals can significantly reduce the mean total cholesterol, triglycerides, and low-density lipoprotein (LDL cholesterol) levels in comparison to those who do not donate blood.
The Bottom Line
Although blood donation plays a crucial role in saving lives, it is equally beneficial for the donor as well. Through several scientific research studies, it has been established that donating blood frequently can reduce the risk of developing cardiac disease.
By bringing down the blood viscosity, preventing excessive iron storage, and reducing blood cholesterol and triglyceride levels, Blood donation plays a vital part in maintaining heart health. Hence encouraging people to come forward for blood donation not only contributes to a healthier society but also can reduce the chances of increasing heart disease universally.
It is of vital importance to promote awareness regarding the beneficial impact of blood donation and encourage more individuals to become regular blood donors. This in turn can contribute to a healthier community. So donate blood, save lives!
