Contrast Water Therapy
Reviewed by the Nimbera editorial team · Last updated May 2026
How to use
Alternate between cold water (10-15 C / 50-59 F) and warm water (38-40 C / 100-104 F) immersion - 1 minute cold, 3-4 minutes warm, repeated 3-4 times per session. End on cold. Use a cold shower and warm bath, or two containers large enough to submerge the affected area. Apply 1-2 hours post-exercise and again the following day.
How it works
Alternating vasoconstriction (cold) and vasodilation (warm) creates a pumping effect in the vasculature, enhancing removal of lactate and inflammatory metabolites from muscle tissue. Cold exposure also reduces nerve conduction velocity, temporarily blunting pain signals.
Where to buy
No purchase required - use home shower and bathtub. For dedicated cold plunge use: Plunge or Ice Barrel brand tubs ($500-$1000), or a large plastic storage container filled with cold water and ice.
Typical cost: Free using home shower and bath. Dedicated cold plunge equipment $500-$1000.
Safety notes
Avoid cold water immersion if you have Raynaud's disease, cold urticaria, or uncontrolled cardiovascular conditions. Do not use ice-cold water on skin with open wounds. Limit cold immersion to 10-15 minutes maximum to avoid hypothermia. Supervise children at all times.
