Regular meditation practice for three months significantly increased galvanic skin response (GSR)—a measure of skin conductance linked to relaxation—in healthy young adults. In a study of 50 medical student volunteers aged 18–25, GSR was measured before and after a program of 20-minute meditation sessions five times per week for three months. The median GSR rose from 267.5 to 534.5, a statistically significant change. The authors conclude that meditation promotes relaxation and may help reduce stress and anxiety by enhancing parasympathetic nervous system activity.
