Rest Day Planner
Plan active recovery on rest days.
About Rest Day Planner
Recovery timing for Rest Day caps how long to stay in cold water based on the temperature and your experience, then estimates the recovery window that follows. Cold exposure benefits are dose-dependent, and safety limits drop sharply as the water gets colder.
Formula
Rest Day
Suggested time caps exposure by water temperature and experience
- experience
- How accustomed the body is to cold exposure
