Hot and cold packs are versatile therapeutic tools used to provide relief from pain and inflammation. Hot packs are typically used to relax and soothe sore muscles, enhance blood circulation, and promote the healing of injured tissues. In contrast, cold packs are applied to reduce swelling, numb sharp pain, and alleviate inflammation in acute injuries, such as sprains and strains. These packs are often utilized in physical therapy, sports medicine, and home care for pain management and recovery.
