What is one primary effect of friction during a massage?

Friction in massage primarily serves to release the tone of twitching muscles. This technique involves the application of pressure and movement across the skin, which can help alleviate tension in the muscles, improve circulation, and promote relaxation. By engaging with the muscle tissue in this way, friction helps to break down knots and reduces spasms, leading to a more comfortable and relaxed state for the client.

While other effects like increasing hydration or stimulating hair follicle growth may occur indirectly during a massage, they are not the primary effects associated with the use of friction specifically. Similarly, enhancing skin pigmentation is not a direct result of friction; rather, it is influenced by various other factors such as sun exposure and skin health. Therefore, focusing on muscle relief through friction is the key aspect in this context.
