Frostbite Guide

Frostbite — Cold Tissue Damage

Proper first aid for frostbite to protect damaged tissues and prevent permanent nerve and blood vessel damage.

Immediate Clinical Assessment Required

Seek medical care immediately if you suspect frostbite. Symptoms include white, grey, or yellow skin, numbness, a hard/waxy feeling, and blisters after rewarming. Never rub or massage the skin.

Step-by-Step Instructions

1

Move Out of the Cold

Move the person to a warm, dry environment as quickly as possible. Remove all wet clothing and insulate them from the ground.

2

Remove Tight Jewelry/Clothing

Gently take off any rings, watches, or tight boots/socks near the affected areas before swelling and inflammation begin.

3

Gently Rewarm the Area

Submerge the frostbitten area in warm (NOT hot) water — ideally between 100°F and 104°F (38°C–40°C). Rewarm for 20 to 30 minutes. If water is not available, use body heat (e.g., placing cold fingers in armpits).

4

Protect the Rewarmed Skin

Gently pat the skin dry. Place clean, dry sterile gauze between rewarmed fingers or toes to keep them separated and prevent friction.

5

Elevate the Affected Area

Keep the rewarned limb elevated above the heart level to reduce severe swelling, pain, and throbbing as circulation returns.

6

Transport to a Medical Facility

Get the person evaluated by medical professionals immediately. Do not allow them to walk on frostbitten feet or toes as this causes further cell destruction.

Do's and Don'ts

Do's

  • Submerge in warm water (100°F–104°F)
  • Handle the frozen areas extremely gently
  • Place sterile gauze between affected digits
  • Keep the rewarmed limb elevated

Don't's

  • Don't rub or massage the frostbitten skin
  • Don't use dry direct heat (heating pads, fires, stoves)
  • Don't pop any blisters that form on the skin
  • Don't allow the area to freeze again after rewarming

Aftercare & Recovery

Hospital treatment includes pain control, wound debridement, infection prevention (antibiotics/tetanus toxoid), and hyperbaric oxygen in severe cases.
Recovery takes weeks to months. The rewarmed skin may stay red, swollen, and painful for a long period, and might experience skin peeling.
Protect the rewarmed area from future cold. Frostbitten skin remains highly vulnerable to cold injury for years.
