Contrast therapy is a treatment method that alternates between hot and cold temperatures to promote healing and reduce pain. This technique can involve using hot packs, cold packs, or even immersion in hot and cold water. The temperature changes help improve blood circulation, reduce inflammation, and relieve muscle tension. Athletes often use contrast therapy after intense workouts or injuries to speed up recovery. By alternating between heat and cold, the body can experience enhanced relaxation and reduced soreness. This therapy is also commonly used in physical therapy settings to aid in rehabilitation and improve overall mobility.
