People in Sheffield are being encouraged to give blood over the Easter holidays.
Health bosses said blood stocks are traditionally low around this time of year.
Amanda Eccles, Senior Marketing Coordinator at NHS Blood and Transplant, said: “During the Easter period we normally give gifts and chocolate to loved ones. By giving blood you could be helping to save lives.
“Blood donations are always needed but it is particularly important to give around Easter as blood stocks are often more vulnerable around public holidays.
“This is due to people going away or spending more time outdoors with family and friends as the weather improves.
“The need for blood never stops and hospitals in England and North Wales need more than 6,000 blood donations every day. I urge both new and returning donors to make a date to donate.”
