HEAT Bed Study

There is a need for treatments that work for major depressive disorder (MDD). We tested the feasibility of combining sauna sessions and cognitive behavioral therapy sessions as a treatment for depression. We recruited 16 adults with MDD to receive 8 weekly cognitive behavioral therapy (CBT) sessions and 8 weekly or 4 biweekly sauna sessions that raised their body temperature to 101.3º F and lasted up to 140 minutes. Midway through the study, we reduced the number of sauna sessions we provided from 8 weekly sessions to 4 biweekly sessions.

Overall, 13 participants completed at least 4 sauna sessions. Out of 16 participants, 12 completed the final assessment and completed 100% of administered self-report depression assessments. The participants who completed the final assessment had a BDI-II (Beck Depression Inventory) reduction of 15.8 points, and 11 of these participants no longer met criteria for MDD (Major Depressive Disorder). Thus, data showed that this mind-body treatment was feasible and showed promise as a treatment for depression.
