These days, health problems are often linked to stress. A well-rested person suffers less exhaustion and fatigue, and is less sensitive to stress. Stress causes hyperfunction of the nervous system, and hypertonicity of the musculoskeletal system, particularly in the back.The back is hypersensitive to reflex stimulation. Stimulation of the muscular and ligament receptors in the different muscle layers of the back, as well as the various skin corpuscles, results in muscle relaxation and the secretion of well-being hormones (endorphin, dopamine...).Reflex back massage brings general relaxation and emotional release.
