Sports medicine experts share a progressive cold exposure protocol for safely building tolerance to ice baths, maximizing recovery benefits while minimizing the cardiovascular risks that have made headlines.
The 8-Week Protocol
Weeks 1-2: End showers with 30 seconds cold water (65°F)
Weeks 3-4: 1-minute cold showers (55°F)
Weeks 5-6: 2-minute cold showers (50°F)
Weeks 7-8: 2-minute ice bath (40-50°F)
Safety Rules
