Cold water immersion is popular for recovery, reducing inflammation, and building resilience. The ideal ice bath temperature is 50°F to 59°F, with safe sessions lasting 2 to 10 minutes. Benefits include improved circulation, faster muscle recovery, mood boosts, and stress reduction. Going below 41°F or staying longer than 15 minutes increases risks like cold shock and hypothermia. Consistency, gradual adaptation, and safe equipment are key for lasting benefits.
