Every day in Singapore, more than 350 bags of blood are needed to save lives. Blood is not only required for accidents and emergencies, it is also for sustaining the lives of patients with disorders like leukaemia, thalassaemia and some types of disorders. In addition, any patient who is undergoing a major surgery would require blood transfusions. With our aging population which means more people living longer but requiring sophisticated health care services and treatments, not only might we expect an increased demand for blood, we may even see a decrease in the donor pool if younger Singaporeans are not stepping up to donate blood.
If the giving others the all-important gift of life is insufficient to persuade you to donate blood, perhaps some health benefits of regularly donating blood will:
- Reduce risk of heart disease and cancer brought about by excess iron.
Excess iron in blood oxidises, damages artery walls and promotes the growth of tumours. According to a study by the American Journal of Epidemiology, regular blood donors are 88% less likely to have a heart attack than non-donors. They also have lower-than-average cancer rates. Excess iron is usually attributed to existing health conditions or imbalanced diet.
- Burn about 650 calories per pint of blood donated.
The body will expend this amount of energy to replace the blood loss. However, you can only donate blood once every two months, so you probably shouldn't count on it as a weight-loss tool.
- Renews your red blood cells
The old has to clear out in order to make way for the new. Blood donation is a save way to remove a significant amount of old blood cells. The new blood cells that replace them will carry more oxygen, helping your body to work better.
Sounds tempting, isn't it? And donating blood on a regular basis really isn't as intrusive, time-consuming or painful as some people imagine it to be.
How long does blood donation take?
According to the Singapore Red Cross, the whole process including administrative procedures and health screening takes about 45 minutes, and the blood donation itself takes about 10-15 minutes. After that, you are free to do light activities. Physically strenuous activities (athletics, heavy lifting) are to be avoided for 24 hours. 45 minutes to save a life or more, that's hardly much to ask for.
Is it painful?
A local painkiller will be applied, so the pain should be very minimal, and only lasting for that brief period when the blood is being drawn.
Possible side effects and how to resolve them?
They vary from person to person, but these are the normal side effects:
- lightheadedness: Lie down with your feet up until the feeling passes
- Bruising where the needle was: apply a cold pack periodically during the first 24 hours after the blood donation
- Soreness in arm: You can take a pain reliever like acetaminophen. Aspirin and ibuprofen should be avoided for the first 48 hours after donation.
The staff at the blood donation drive will advise you accordingly, so don't worry.
You should not experience any prolonged/permanent side effect or scarring. For faster healing, you should drink plenty of water and consume an iron-rich die after donating blood.
Who can donate blood?
- Aged 16-60 (people below 18 will require parental consent)
- weigh at least 45kg
- in good health
- no symptoms of infection (e.g. sore throat, cough, runny nose, diarrhoea) for at least one week before
- did not have fever in the last three weeks
- have a haemoglobin level of at least 12.5g/dl (A test will be administered by trained nurses at the donation site)
Donating blood is very convenient. You can book an appointment via Singapore Red Cross's website.
There are not only 4 blood banks operating across Singapore, but regular community blood drives are also organised at various locations.
So if you have some free time and are in good health, think about the less fortunate struggling for their lives. A little sacrifice on our part can make a huge difference to their lives and earn you some great karma. Those with rare blood types especially should donate. We hate to think of the worst, but life is unpredictable but you never know when you'll also need blood from a fellow rare type.
