Are body temperature and depression linked? Science says, yes

The findings shed light on how a novel depression treatment method might work, said Ashley Mason, PhD, the study’s lead author and associate professor of psychiatry at UCSF Weill Institute for Neurosciences. A small body of existing, causal studies has found that using hot tubs or saunas can reduce depression, possibly by triggering the body to self-cool, for example, through sweating.

“Ironically, heating people up actually can lead to rebound body temperature lowering that lasts longer than simply cooling people down directly, as through an ice bath,” said Mason, who is also a clinical psychologist at the UCSF Osher Center for Integrative Health. “What if we can track the body temperature of people with depression to time heat-based treatments well?”

“To our knowledge, this is the largest study to date to examine the association between body temperature – assessed using both self-report methods and wearable sensors – and depressive symptoms in a geographically broad sample,” added Mason. “Given the climbing rates of depression in the United States, we’re excited by the possibilities of a new avenue for treatment.”
