The Role Of Cold Therapy Includes The Following Aspects

① Anti-inflammatory: Cold makes blood vessels constrict, cell permeability changes, local exudation and bleeding are reduced, and local inflammatory edema is reduced.

② Analgesia: Cold reduces nerve excitability and slows down the conduction speed, so it can relieve pain.

③ Antispasm: It is the result of decreased muscle excitability and contractility.

④Reducing fever.
