You sprain an ankle during a football match. Do you apply heat or ice to the injury? For most people, the logical answer is to apply an ice pack to the injured area. But do all injuries need cold? Most of the time ice is the better choice unless there is compromised circulation in that area. Ice is usually preferred to decrease inflammation, swelling and pain, all of which are commonly associated with an acute injury.
HEAT: Applying heat to an injury brings more blood to the area brings more blood to the area and reduces joint stiffness and muscle spasm, which makes it useful when muscles are tight. Heat relaxes muscles and allows blood vessels to expand and deliver more oxygen and nutrients to the area. If it is an open injury or cuts, avoid heat because it promotes more bleeding.
COLD: Cold is good for an injury or inflammation where tissues are damaged. It helps relieve pain by numbing the affected area and reduces swelling and bleeding. Cold is good for a new injury especially in the first 24 - 48 hours.
