What is the recommended bucket immersion temperature for ice immersion?

• A. 30° to 40°F
• B. 40° to 50°F
• C. 60° to 70°F
• D. 70° to 80°F

Answer: (B)

Ice immersion works by cooling superficial tissues quickly to help reduce pain, swelling, and inflammation after an injury. The bucket temperature should be cold enough to produce vasoconstriction and a noticeable cooling effect, but not so cold that it risks tissue damage during a typical brief session. A common target for bucket immersion is about 40 to 50°F (roughly 4 to 10°C). This range provides effective cooling within a safe time frame (often around 10 to 15 minutes) and is generally tolerable for most people when they begin with shorter exposures and monitor how the skin and sensation respond. Warmer temperatures won’t achieve the same cryotherapy effect, while much colder temperatures increase the risk of frostbite and nerve irritation. So, choosing a cooler but not extreme range like 40–50°F aligns with the goal of rapid cooling while maintaining safety during the immersion. If the skin becomes numb, pale, or painfully uncomfortable, the session should be ended and warmth restored.
