Hot Water Immersion Therapy for Mental Health

Evaluating Whether Lower-limb Hot Water Immersion Therapy Can Improve Symptoms in Individuals Diagnosed With Depression, Anxiety, and Post-traumatic Stress Disorders

In 2016, it was estimated that nearly 1 billion people worldwide were affected by a mental or addictive disorder, and were associated with considerable excess mortality. Acute heat therapy sessions (e.g. whole-body heating or foot immersions) have been shown to improve symptoms in individuals diagnosed with common mental health illness such as major depressive disorders and reduce anxiety.

This study will assess the impact of an at-home 8-week lower-limb immersion in hot water on symptom severity in patients diagnosed with major depressive disorder, generalized anxiety disorder, and PTSD.
