There are many myths about blood donation. Below we present common claims followed by the evidence-based facts to help you make an informed decision.
Myth: Donating blood is painful and dangerous
Fact: Donors may feel a brief pinch when the needle is inserted. Donations are performed by trained staff using sterile single-use equipment and are generally very safe.
Myth: You can catch diseases from donating blood
Fact: Donation uses sterile, single-use needles and strict infection control procedures — the process does not transmit infections to donors.
Myth: Donating blood makes you weak for weeks
Fact: Fluid volume returns quickly within 24–48 hours and most energy returns in a few days; red cell mass can take several weeks to recover, which is why donation intervals are recommended.
Myth: People with tattoos can't donate
Fact: Policies vary by country; recent tattoos or piercings may require a short waiting period depending on local infection-risk rules, but many donors with older tattoos can donate.
