What is the typical duration and effect of an ice bath?

• A. 5-10 minutes to cause vasoconstriction and reduce blood flow to the area
• B. 5-10 minutes to cause vasodilation and increase blood flow to the area
• C. 15-20 minutes to cause cooling but is less effective
• D. 1-2 minutes to relieve soreness

Answer: (A)

Ice baths work by cooling the tissues enough to trigger vasoconstriction, which reduces blood flow to the area. A typical duration is 5–10 minutes, which provides sufficient cooling to achieve this effect without risking tissue damage. Longer durations (like 15–20 minutes) can increase frostbite risk and may offer no extra benefit, while very short exposures (1–2 minutes) might not achieve meaningful cooling. The result is reduced swelling and a calmer area, rather than increased blood flow.
