What main benefit does cryotherapy provide in treatment?

Cryotherapy primarily offers the benefit of reducing swelling. The application of cold temperatures on affected areas decreases blood flow, which in turn helps to minimize inflammation and swelling in tissues. This is particularly valuable in the immediate treatment of injuries, where swelling can hinder mobility and prolong recovery. By alleviating swelling, cryotherapy aids in managing pain and often enhances the overall healing process.

In contrast, options like increasing blood flow, building muscle strength, and improving flexibility do not accurately reflect the effects of cryotherapy. Increasing blood flow is typically associated with heat application, while muscle strength and flexibility improvements are outcomes influenced by specific exercise and rehabilitation programs rather than cold therapy.
