Aurora, Colo. (January 16, 2025) – Subzero temperatures arriving across the Front Range this weekend put Coloradans at a heightened risk of frostbite. Frostbite occurs when skin and underlying tissues freeze, causing damage that can become permanent if untreated. Recognizing the symptoms and acting quickly can help prevent severe outcomes.

Frostbite can happen quickly in extreme conditions. When the temperature is 5°F and the wind speed is 30 mph, frostbite can develop in just 30 minutes. At -5°F with the same wind speed, frostbite may set in within 10 minutes.

Common symptoms of frostbite include:

Redness or pain in the affected area, white or grayish-yellow skin, firm or waxy skin, numbness, and, in severe cases, blisters or blackened skin. If left untreated, frostbite can lead to long-term effects like nerve damage, muscle weakness, chronic pain, or even amputation.

If you suspect frostbite, UCHealth’s Burn and Frostbite Center recommends:

• Prevent additional exposure to the cold.
• Rewarm the affected area in warm (not hot) water for 15–30 minutes.
• Keep the affected area elevated to reduce swelling.
• Take over-the-counter pain medication like ibuprofen if warming is painful.
• Avoid walking on frostbitten feet or toes.

If the skin appears blue, bluish-gray, or blisters form when the area begins to warm, seek medical attention immediately.

To reduce your risk, dress in warm layers, limit time outdoors, and stay alert to signs of frostbite. For more information on frostbite and cold-weather safety, visit UCHealth’s frostbite resource page.
