Cold application may decrease coordination and strength. Rewarming takes about how long?

Explanation:
Rewarming after cold therapy is about letting normal nerve and muscle function return as tissue temperature rises. Cold slows nerve conduction and dulls muscle response, so coordination and strength drop. As warmth returns, blood flow and metabolism pick up, nerve signals resume, and motor control improves. That recovery isn’t instantaneous and requires a moderate amount of time for the system to normalize. In typical practice, this rewarming period is about twenty to thirty minutes. Shorter times aren’t enough for full restoration, while a much longer wait isn’t necessary and can interfere with therapy or risk re-cooling. Warming happens gradually, not immediately, which is why the 20–30 minute range is recommended.
