Hot stone massage involves the application of water-heated basalt stones to key points on the body, creating sensations of comfort and warmth. The direct heat relaxes muscles, allowing greater intensity and deeper pressure than with regular massage. Cool marble stones are used as a contrast to create a deep circulatory effect within the body. Some of the benefits of hot stone massage include: helps relieve muscle tension and pain, may help relieve symptoms of autoimmune diseases like fibromyalgia and arthritis, reduces stress and anxiety, promotes deep relaxation, encourages better sleep, and may boost immunity.
