Feeling faint

Some people can feel faint or unwell after donating, but most recover quickly.

If you felt faint during or after your donation, we advise you to:

  • drink plenty of fluids such as water or juice, and have a salty snack
  • eat your normal, regular meals
  • avoid hot rooms and hot showers/baths
  • avoid vigorous exercise or rushing about
  • avoid standing for long periods

What to do if you feel unwell

If you start to feel faint or unwell after you have left the donation session, we advise you to:

  • tell someone, either a friend or family member if possible, and ask them to keep an eye on you
  • lie down and raise your legs if you can
  • get up slowly when you feel well enough, drink plenty of fluids and eat a salty snack

How to prepare for your next donation

Follow this advice to reduce the chance of you feeling unwell at your next donation.
