A hot pad is a way to manage body pain with the use of thermotherapy or what is known as method of heat application. Localized application of heat causes dilation in the blood vessels and improves perfusion on the targeted tissues. Pain can occur due to muscle strain or exertion causing tension in muscles and tissues. Heat application eases the pain by improving the flow of oxygen and nutrients in injured tissues and fastens the healing process. Heat stimulates the sensation in the skin, thereby decreasing the pain signals being transmitted to the brain. It also helps in increasing flexibility of tissues around the injured area.Hot pad can be used for treatment in any injuries or any pain where heat can provide immediate relief.
