Donating blood is an active way of helping others and the whole of society.
Specialist medical staff are on hand at all times during the donation, which is a simple, safe and painless procedure. There is no risk for donors of giving blood, and it may help patients in Catalonia recover more quickly.
Despite medical and technological advances, blood cannot currently be made. The only way of getting hold of it is via blood donations from people who give blood.
Because each blood donation provides three different blood components, each with its own role in treating patients, it helps up to three different people.
Because the need for blood is constant, so is the need for donations. Every day, all the hospitals and clinics in Catalonia need blood and blood components to treat patients, since most surgical interventions and a great number of medical procedures require blood transfusions.
Transfusions of blood and blood components have become an essential part of healthcare today.
We don't just need to give blood in the event of tragedies or emergencies. Instead, it should be a normal and routine part of our lives. Regular blood donations mean that there will be sufficient amounts of safe blood in stock.
Remember that men can give blood up to four times a year - women up to three times -providing there are at least two months between donations.
The WHO has established an optimum threshold of between 43 and 45 donations per thousand inhabitants per year
