Snehan involves the external application of warm medicated oil on the body, often combined with therapeutic massage. The mechanical stimulation from massage activates sensory mechanoreceptors in the skin and underlying tissues, which in turn modulates the autonomic nervous system, particularly enhancing parasympathetic activity. This leads to reduced stress, lower cortisol levels, and improved relaxation.
The warm oil application improves cutaneous blood flow and microcirculation, enhancing nutrient delivery and waste removal at the tissue level. Lipid-soluble phytochemicals in medicated oil are absorbed transdermally, exerting anti-inflammatory, analgesic, and antioxidant effects. Additionally, massage and oleation improve lymphatic drainage, reduce muscular stiffness, and promote connective tissue flexibility.
