Instead of signing up for a gym class the NHS Blood and Transplant unit in Hounslow are asking people to take an hour out of their time to book an appointment and make a life-saving blood donation.

A number of venues have been setup for people to go along and donate blood in Feltham, Hounslow, Chiswick and Isleworth, up until May.

Each blood donation can potentially save or improve up to three lives.

Nelson Olivares, senior marketing coordinator at NHS Blood and Transplant said: "The beginning of the year is a great time to make changes to your lifestyle and it is the perfect time to give blood. If knowing that your blood is helping to save sick and injured people isn’t satisfaction enough, we can also guarantee donors a warm welcome, a refreshing drink and a biscuit when they donate. This year, make a resolution you will want to keep and help us save lives at the same time."

Universal blood group 0 Rh Negative is often in short supply and rarer blood groups include A Rh Negative, B Rh Negative and AB Rh Negative. To book an appointment visit www.blood.co.uk or call 0300 123 2323 or download the app NHSGiveBlood.
