A clinical trial spearheaded by Massachusetts General Hospital discovered that participants with moderate-to-severe depression saw notable improvements in their symptoms through heated yoga sessions. As reported in a Harvard Gazette article, the eight-week trial suggests that heated yoga could be a therapeutic choice for depression sufferers.
On the trial, participants numbering to 80 were separated into two groups: one attended Bikram yoga sessions lasting 90 minutes in a 105°F room and the other was placed on a waiting list, completing the yoga intervention post-waitlist period. At the end of the trial, researchers garnered the discovery that those who participated in the heated yoga sessions had more decreased depressive symptoms than their waitlist counterparts—as gauged by the Inventory of Depressive Symptomatology (IDS-CR) scale, which is clinician-rated.
The positive effects of the trial were still observable in participants who only attended half of the suggested yoga sessions, hinting that even one heated yoga session weekly could have an impact on depression. Lead researcher Maren Nyer, the Director of Yoga Studies at the Depression Clinical and Research Program at Massachusetts General Hospital and Assistant Professor of Psychiatry at Harvard Medical School, said, "Yoga and heat-based interventions could potentially revolutionize the way depression patients are treated by offering a non-medication–based approach with bonus physical benefits."
Researchers now aim to identify the separate contributions of heat and yoga in the observed clinical effects. It's deemed necessary to pursue future research comparing heated to non-heated yoga, in order to discern if the inclusion of heat offers unique benefits beyond yoga alone, particularly in light of encouraging evidence for full-body hyperthermia, as referenced in the Harvard Gazette article.
As research in this field continues, the potential for yoga to become a viable treatment option for improving mental health remains a promising area that certainly merits additional study and thorough scrutiny.
