Tissue freezes at -2°C — fingers, toes, and the cold-injury science

Survive Frostbite Quiz: Test Your Cold-Injury Knowledge

Anna Bågenholm survived frostbite-level cold with a body temperature of 13.7°C — lower than any other adult ever resuscitated, and she returned to medical practice as a doctor. Frostbite is a deceptively complex injury: tissue freezes at around -2°C, but rewarming is a one-shot procedure where mistakes can cost a finger. This quiz covers degree classification, the rewarming protocol, hypothermia stages, and the legendary cold-survival cases that shaped modern wilderness medicine.

How It Works

Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.

What You'll Learn

You'll learn the four frostbite degrees, the 37–40°C rewarming bath, the role of tPA and iloprost, hypothermia thresholds, the 'no one is dead until warm and dead' rule, wind-chill physiology, and lessons from Beck Weathers, Anna Bågenholm, and Antarctic explorers.

Frequently Asked Questions

What is frostbite?

Frostbite is the freezing of body tissue once skin temperature drops below the freezing point of cellular fluid (around -0.55°C). Ice crystals damage cells directly, while reduced blood flow worsens the injury.

What temperature is dangerous?

Frostbite risk rises sharply once ambient temperatures fall below about -10°C. With wind chill of -28°C, exposed skin can freeze in 30 minutes; at -50°C, it can freeze in less than 2 minutes.

Should you rub frostbitten skin?

No. Rubbing frozen tissue causes mechanical damage from ice crystals and worsens the injury. Standard treatment is rapid rewarming in 37–40°C water, ideally only once you're certain the area won't refreeze.
