What is the recommended cold whirlpool temperature and duration?

• A. 45° to 50°F for 30–40 minutes
• B. 55° to 65°F for 5–15 minutes
• C. 65° to 75°F for 20–30 minutes
• D. 75° to 85°F for 40 minutes

Answer: (B)

Cold whirlpool therapy uses cold water to reduce inflammation and pain by causing vasoconstriction and lowering tissue metabolism. The agitation from the whirlpool helps transfer cold more effectively, but you want the water to be cool enough to trigger those protective responses without being so cold that it risks tissue damage. A mid-range cool temperature with a brief exposure provides that balance: it achieves the anti-inflammatory and analgesic effects while keeping the risk of cold injury low. If the water is too cold and the session lasts too long, you can provoke frostbite or numbness; if it’s too warm or the session is too long, you won’t get the cryotherapy benefits and edema or pain may persist. So the best approach is a cool, not freezing, water temperature for a short duration to safely maximize therapeutic effects.
