What is the treatment time for ice immersion?

• A. 3-5 minutes
• B. 12-15 minutes
• C. 20-25 minutes
• D. 60 minutes

Answer: (B)

Cooling the tissue to a level that slows metabolic processes and reduces swelling is the goal of ice immersion. A duration around 12 to 15 minutes hits that sweet spot: it provides enough time for the superficial tissues to reach an effective cooling level without pushing into unsafe territory. Shorter times, like 3–5 minutes, often don’t produce enough cooling to meaningfully limit edema or metabolic rate. Longer sessions, such as 20–25 or 60 minutes, increase the risk of frostbite or nerve injury and tend to offer diminishing additional benefits once the tissue is adequately cooled. If you’re applying ice immersion, watch for numbness, color changes, or excessive discomfort and stop if these occur.
