The NHS is urging people across Yorkshire to give blood this summer before they head off on their holidays.
Blood stocks reduce during the summer months as people enjoy the warm weather and have less time to donate, but the health service remains reliant on 7,000 people giving blood every day across England and North Wales.
There is particularly strong demand for those with blood groups B Rh negative and O Rh negative.
There will be blood donation sessions at Morley Town Hall on August 7 and August 20, from 2pm - 4pm and 5pm - 7.30pm.
Donna Batty, lead donor relations manager for Yorkshire and the North said: “We know people are busy and especially in the summer but we’re asking that they remember those hospital patients who need blood to save or improve their lives. We’re asking our donors to please make an appointment to donate before they go away.
“If you’ve never given blood before, why not make this summer the time you join our donors an make a difference to others? Each blood donation can potentially save up to three lives.”
Anyone aged between 17 - 65 and weighing more than 50 kg (7 stone 12lbs) can give blood. Appointments can be made at www.blood.co.uk.
