A series of studies into the antidepressant effects of yoga have returned positive results.
Since its rise to western popularity in the 1980s, people have enthused about the health benefits of yoga. One of the most frequently touted claims is that practicing yoga can aid your mental health. However, empirical evidence to back up these claims has often been difficult to find.
Lindsey Hopkins, a researcher at the San Francisco Veterans Affairs Medical Centre, has set out to plug the gap. Her study focusses on the antidepressant effects of hatha yoga, a branch of the discipline that emphasises physical exercise, meditation and breathing exercises in order to enhance wellbeing. Twenty-three male veterans participated in the study, attending twice-weekly classes for eight weeks. The result? All the participants with elevated depression scores before the program experienced a significant decrease in symptoms after their involvement.
Nina Vollbehr, who works at the Centre for Integrative Psychiatry in the Netherlands, has also investigated yoga’s antidepressant potential. Her first study involved tracking twelve patients, each of whom had experienced depression for an average of eleven years, as they participated in nine weekly yoga sessions. The participants’ levels of depression, anxiety, stress, rumination and worry were measured before they took part, immediately after the program and then again four months after the program ended. The data collected showed a decline in the symptoms of anxiety, stress and depression throughout the program, the benefit of which persisted for the four months afterwards. On the other hand, rumination and worry did not decrease during the program. However, a slight reduction in rumination and worry symptoms was found in the four month follow up.
Vollbehr’s second study compared yoga to another relaxation technique. In it, seventy-four mildly depressed university students were given thirty minutes of instruction on either yoga or relaxation. They were then asked to perform the same exercises at home for eight days, with the aid of a video. Immediately after the study, it appeared that both yoga and relaxation both had the same positive effect, but the two month follow up indicated that the yoga group had significantly lower scores for depression, anxiety and stress than those who had followed the alternative relaxation program.
Now, it is clear that the sample sizes in the studies are small and that the research into yoga as a treatment for depression is still very much in its preliminary stages. However, according to Jacob Hyde, a military psychologist at the University of Denver, the concept of yoga as a complementary or alternative mental health treatment certainly seems promising.
