Two people with bandages on their arms after donating blood form a heart shape with their hands, symbolising care and generosity.
Blood donation should be a simple act of kindness, but it is often surrounded by myths and fear. Friends, relatives or social media posts may pass on half-truths that sound convincing but are not medically accurate. These misconceptions stop many healthy people from ever visiting a blood donation centre.
Clearing these myths is essential. When potential donors understand the facts, they are more likely to step forward and become regular supporters of patients in need.
Fact: Most healthy donors feel completely normal within a short time after donating. Mild tiredness for a few hours is common, but it usually settles with rest and fluids. Guidelines on how often a person can donate are based on how long the body needs to replace the donated blood.
As long as you follow recommended intervals and eat and drink sensibly, blood donation should not cause prolonged weakness.
Fact: Approved blood centres use sterile, single-use needles and blood bags. They are opened in your presence and discarded after one use. Strict hygiene protocols protect both donors and recipients.
There is no risk of getting infections like HIV or hepatitis from donating blood at a properly managed and licensed centre.
Fact: The body is constantly producing new blood cells. After a donation, your system starts replacing the volume and cells that were removed. This process happens naturally. The minimum gap between donations is designed based on how long this recovery typically takes.
If you maintain a healthy diet and lifestyle, your blood levels remain within safe limits over time.
Fact: Weight requirements exist for a reason. People below a certain weight may not tolerate the temporary loss of blood volume well. The limit protects the donor from feeling faint or unwell after donation.
If you do not meet the weight criteria, focus on reaching a healthier weight first. Once you qualify, you can safely register as a donor.
Fact: Many deferrals are temporary. Low haemoglobin, recent illness, certain medications or recent travel can result in a short-term deferral. Once the reason is resolved and the waiting period is over, you may become eligible again.
It is always better to ask the centre when you can return, rather than assuming that the rejection is permanent.
Before donation, check that you meet the age and weight criteria. Ensure you have not donated blood in the recent restricted period. Inform staff about any ongoing medications or medical conditions. Eat a light meal and stay hydrated.
During donation, tell the staff if you feel anxious, dizzy or uncomfortable at any point. Try to relax your muscles and breathe steadily. Follow instructions on squeezing or relaxing your fist during the procedure.
After donation, rest as advised, have the snack provided and drink extra fluids. Avoid running, gym workouts or heavy labour on the same day. Seek medical advice if you feel unwell for an unusually long time.
Rely on information from medical professionals, not rumours. Ask questions at the donation centre whenever you have doubts. Maintain a healthy lifestyle to improve your eligibility. Use Blood App or similar platforms to stay updated on guidelines. Encourage others by sharing your positive donation experiences.
