Hot stone massage may relieve painful conditions such as fibromyalgia. Fibromyalgia is a condition that causes widespread, chronic pain. According to a 2002 study, people with fibromyalgia who received a 30-minute massage slept longer, had fewer trigger points, and had decreased levels of substance P (a substance involved in transmitting pain signals) than people with the condition who received relaxation therapy. More research is needed, however, before massage becomes a standard fibromyalgia treatment.

A 2013 studyTrusted Source found that people with rheumatoid arthritis may benefit from a moderate-pressure massage, such as hot stone massage. Participants in the study experienced less pain, greater grip strength, and a greater range of motion after one month of massage therapy.
