If you’ve ever taken a yoga class, you probably know that it can help relax your body and your mind. Now, several new studies suggest that practicing yoga may also ease depression.

But the leader of a session on yoga and depression held Thursday at the annual meeting of the American Psychological Association in Washington, D.C., emphasized the research is preliminary.

“At this time, we can only recommend yoga as a complementary approach, likely most effective in conjunction with standard approaches delivered by a licensed therapist,” psychologist Lindsey Hopkins said in an APA news release.

“Clearly, yoga is not a cure-all. However, based on empirical evidence, there seems to be a lot of potential,” added Hopkins. She is a clinical psychologist at the San Francisco VA Medical Center.

Hopkins conducted a study that included 23 male veterans who took part in twice-weekly hatha yoga classes for eight weeks. Hatha yoga emphasizes physical exercises, along with meditative and breathing exercises.

Participants who began the study with elevated depression scores saw their symptoms ease significantly after eight weeks, the findings showed.

A second study looked at Bikram (hot) yoga and included 52 women aged 25 to 45. Those who did twice-weekly classes for eight weeks had sharply reduced depression symptoms compared to a control group that did not take the classes.

Another study of 29 adults found eight weeks of at least twice-weekly Bikram yoga significantly eased depression while also improving quality of life, optimism, and mental and physical functioning.

A number of other studies have yielded similar findings, the news release said.

Research presented at medical meetings should be viewed as preliminary until published in a peer-reviewed journal.
