What is one benefit of using ice therapy (cryotherapy) after an injury?

The benefit of using ice therapy, or cryotherapy, after an injury primarily lies in its vasoconstrictor effect. When ice is applied to an injured area, it causes the blood vessels to constrict, which reduces blood flow to the area. This decrease in blood flow helps to limit swelling and inflammation, which can otherwise exacerbate damage and prolong recovery.

By reducing inflammation, ice therapy can help control pain and minimize tissue damage, which are critical factors in the initial stages of injury management. The controlled application of cold also numbs the sensory nerves in the area, leading to immediate pain relief. Therefore, the ability to induce vasoconstriction is a key benefit of ice therapy in managing acute injuries.
