Donating blood is a small decision you can make that can have an immeasurable impact. Taking around an hour out of your day and braving a tiny pin prick could mean the difference between life and death for someone in need.
Each person has between 3.5 and 5.5 liters of blood, yet donating one unit – just 525ml – can save the lives of as many as three people.[1] On the other hand, car accident victims can require upwards of 50 units[2]. Blood is always in demand, and demand is always shifting. Canada’s lifeline is fragile; factors as commonplace as bad weather or as terrifying as natural disasters can destabilize systems and deplete stores, leaving people’s lives hanging in the balance.

Managing hurdles
| If you’re worried about… | Try… |
| Needle pain/fear | Looking away from the needle, breathing slowly and deeply, distracting yourself (with music, talking, reading, playing a game or watching a video on your phone, etc.)[3] |
| Soreness after donating | Icing the area, elevating your arm, gentle movement.[4] |
| Fainting/feeling lightheaded | Using the Applied Muscle Tension (AMT) technique – tensing major muscle groups to increase blood pressure.[5] |
| Irritation from the materials | Alerting staff of allergies (e.g. latex, certain disinfectants, etc), removing the bandage after donating and washing the area with soapy water.[6] |
| My blood type being too rare/not being rare enough to matter. | Remembering that donations of all types are always needed. Less common types can be harder to source (meaning supply is lower), while more common types are transfused more often (meaning demand is higher). Either way, someone out there could benefit from your donation.[7] |
