Frostbite happens when parts of the skin and other tissues
freeze due to low temperatures. Frostbite usually affects
the fingers and toes as they are the parts of the body
furthest from the heart.
If someone has severe frostbite then they might permanently lose
all feeling in that part of their body. Frostbite can also lead to
gangrene, when the blood vessels and soft tissues become
permanently damaged leading to death of the tissue.
Frostbite usually happens in freezing or cold and windy weather.
People who cannot move around are more likely to get it. Someone
with frostbite will probably have hypothermia, so be prepared to treat them for

What to look for - frostbite
If you think someone has frostbite, there are four key things to
- ‘Pins and needles’ to begin with
- Paleness, followed by numbness
- Hardening and stiffening of the skin
- Change in skin colour: first white, then blotchy and blue. On
recovery, the skin may be red, hot, painful and blistered. If they
get gangrene, the tissue may become black due to the loss of blood
supply and death of the tissue.
What you need to do - frostbite
• First, encourage them to put their hands in their
armpits. Then help move them indoors or to somewhere warm.
• Once inside, gently remove anything constricting like
rings, gloves or boots.
• Next, warm the body part with your hands on your lap, or
under their armpits. Don’t rub it though because this could damage
their skin tissue. (If there is a danger of it refreezing then
don’t warm it up yet as this can cause more damage).
• Place the body part in warm (not hot) water at around
40°C (104°F) and be careful not to put it near direct heat as this
can cause more damage. Dry it carefully and put on a light
dressing, ideally a gauze bandage from your first aid kit.
• Once you’ve done that, help them to raise their limb to
reduce swelling, with cushions or a sling for instance.
• Advise them to take some painkillers if they have some
(paracetamol for example).
• Then take or send them to hospital, keeping their limb
