Massage is widely used in all cultures to evoke feelings of deep relaxation and reduced anxiety. The anxiety-reducing and mood enhancing benefits of massage are probably related to changes in EEG activity, decreased levels of cortisol and increased activity of the parasympathetic nervous system, which acts automatically to calm the body and brain during stress. Numerous studies show that moderate pressure massage is more effective than light pressure massage for reducing pain associated with different medical problems including fibromyalgia and rheumatoid arthritis.
