H.A.R.M. stands for Heat, Alcohol, Re-injury, and Massage. It is a guideline used in sports medicine to help individuals avoid worsening injuries. Each component represents a factor that can hinder recovery and increase the risk of further damage to the body. The H.A.R.M. principle advises against exposing an injured area to heat, consuming alcohol, returning to activity too soon, or receiving massage therapy immediately after an injury. By following these guidelines, individuals can promote better healing and reduce the likelihood of complications during recovery.
