Abstract

Protection against age-related immune suppression is important in elderly individuals. This study determined the effect of yoga on mucosal immune function and mental stress. Saliva samples were collected from 23 adult women (age: 60.4 ± 10.4 years) before and after 90 minutes of yoga stretching or rest to measure secretory immunoglobulin A (SIgA), cortisol, and testosterone. The SIgA concentration and secretion rate were significantly higher after yoga than before (p <.05). The cortisol concentration and secretion rate were lower and testosterone secretion rate higher after yoga (p <.05). Yoga stretching can reduce stress and enhance mucosal immune function in elderly women.
