5 Ways donating blood benefits your health

The 14th of June was World Blood Donor Day, when we celebrate those who help save lives through the simple yet profound act of donating blood. It’s a great reminder of how vital blood donation is, especially in South Africa, where the need for blood is constant and urgent.

Just one unit of donated blood (around 450ml) can save up to three lives, yet in South Africa, less than 1% of the population are active blood donors. While we mainly focus on the lives saved through blood donation, many people don’t realise that there are direct health benefits for the donor themselves. In honour of World Blood Donor Day, here are five ways that giving blood regularly can benefit your overall health:

1. It’s a free mini-health screening

Each time you donate blood, you’ll undergo a quick screening process to check your pulse, blood pressure, iron levels and temperature. Regular monitoring can be a good way of flagging potential health concerns you may not have noticed, like low iron, high blood pressure or an irregular heartbeat. While this “mini-screening” certainly isn’t a replacement for a regular GP visit, it can be a valuable tool to help you stay in tune with your body and pick up any minor issues before they become a more significant health concern. These mini-screenings are also helpful if you don’t have the time or money for frequent medical checkups.

2. It regulates your iron levels

Iron plays a vital role in the body by helping red blood cells carry oxygen. While having low iron levels in your blood can be harmful, high levels can also be dangerous. Known as hemochromatosis, high iron levels are linked to an increased risk of heart disease, liver problems and even diabetes. Donating blood regularly stimulates the regulation of iron levels in the body, which negates this risk. According to the American Journal of Epidemiology, blood donors are 33% less likely to suffer from cardiovascular disease and 88% less likely to suffer a heart attack. Other studies have shown that regular blood donation also reduces oxidative stress in the body, which is one of the main contributors to cardiovascular disease, chronic inflammation and arterial damage.

3. It stimulates new blood production

Each time you donate blood, your body is stimulated to produce new red blood cells to replace those that have been lost. This process helps keep your blood fresh and makes your circulation more efficient, which allows oxygen to be delivered to your organs and tissues more efficiently. Stimulating your body to produce new blood cells in this way can also be particularly helpful as you age, when your body becomes less efficient at cell renewal. While this is not a miracle cure by any stretch, it’s a gentle nudge for your body to stay responsive, balanced and keep its internal rhythms in check.

4. It can lower your medical costs

Donating blood means you’re proactively managing your health: as well as being aware of health markers, you’re regulating your iron levels and stimulating new blood production at the same time. By being healthier in these small ways, you can also help reduce your medical costs by being sick less often and needing less medication. If you belong to a medical aid like Fedhealth, their flexiFED medical aid plans allow you to only pay for day-to-day cover when you need it. The healthier you are, the less this cover will need to be, which means you could end up paying less for your medical aid each month.

5. Your mental health gets a lift

While you may be giving blood to help others, you’re also taking care of your mental resilience at the same time. Donating blood is personal, generous and empowering: after all, you’re doing something that directly impacts someone else’s life. Because of this, donating blood has a positive psychological effect by activating the brain’s reward pathways that can improve your mental wellbeing, lower rates of depression and anxiety and even reduce feelings of isolation or disconnection. Studies have also shown that altruistic behaviour triggers the release of feel-good chemicals like endorphins, oxytocin and dopamine that enhance mood and reduce stress. In addition, a study in the Journal of Health Psychology found that people who volunteered had a significantly reduced mortality risk than those who had never done so.

We don’t often see blood donation as something we do for ourselves, which makes sense when we think of the profound benefit it has in saving the lives of others. But giving blood also benefits you by making you more aware of your health, enabling a mini-reset and giving you a psychological lift. While it only takes about 30 minutes to donate blood, the positive effects last far longer. This World Blood Donor Day, let’s remember why giving a little does much more than you think.
