What is the purpose of using a heat pad during a massage?

Using a heat pad during a massage primarily serves to relax tight muscles. The application of heat increases blood flow to the area, which in turn helps deliver oxygen and nutrients necessary for muscle repair and recovery. This improved circulation can also alleviate stiffness and tension in the muscles, making them more pliable and receptive to manipulation during the massage.

Heat can also stimulate sensory receptors in the skin, which helps to reduce pain perception, further aiding in the relaxation of both the muscles and the overall experience for the client. It is an effective preparatory method that can enhance the outcomes of various massage techniques by ensuring that the muscles are warm and flexible.

The other options do not accurately reflect the physiological effects or purposes of using a heat pad in the context of massage therapy.
