Can sauna help with depression? Science says "Yes, it can".
Mental well-being is no longer just about therapy and medication—science is uncovering how habits like sauna therapy can be a powerful, enjoyable addition to your mental health toolkit. At Forge, we believe transformative wellness should be accessible to everyone, and regular sessions in an infrared home sauna may offer exactly the mood-boosting edge you’re looking for—rooted in real research, not just good vibes.
The Proven Link Between Sauna Use and Mental Health
You may already know that stepping into a sauna melts away physical stress. But recent scientific studies reveal infrared saunas can significantly reduce symptoms of depression and anxiety, help regulate mood, and even enhance cognitive clarity.
A 2024 clinical trial from UCSF treated adults with major depressive disorder using combined infrared sauna therapy and cognitive behavioral therapy. The findings were stunning: over 90% of participants no longer met the criteria for major depression after just eight weeks of combined treatment, indicating a dramatic reduction in depressive symptoms123.
A randomized clinical study found that patients using far-infrared sauna therapy twice weekly for four weeks saw increased serotonin levels—the essential “happiness molecule”—and a measurable drop in oxidative stress markers linked to depression. This physiological improvement was linked directly with reduced depressive symptoms and better sleep45.
Regular sauna use (4–7 times per week) has been associated with significantly lower risks of developing psychotic disorders—up to a 78% reduction compared to infrequent users46.
Why Does Heat Therapy Work for the Mind?
Infrared saunas raise your core body temperature gently, which causes a cascade of mental health benefits:
Balanced Stress Hormones: Heat exposure helps lower cortisol (the stress hormone) while boosting serotonin and endorphin levels, leading to improved mood and resilience to stress578.
Deep Relaxation: Sauna sessions activate the parasympathetic “rest and digest” branch of your nervous system, leading to profound relaxation and a calming reset for both body and brain5.
Better Sleep Quality: Poor sleep often goes hand-in-hand with depression and anxiety. Studies show that sauna users report up to 83% improvement in sleep quality after just a single session—a key foundation for solid mental well-being5.
Cognitive Benefits: Recent brain imaging studies confirm that post-sauna recovery leads to enhanced brain relaxation and improved cognitive efficiency, helping you think clearer and feel more mentally refreshed91011.
What Do the Numbers Say About Sauna Use and Mental Health?
Make Sauna Therapy Part of Your Mental Wellness Routine
How often? Most studies recommend 15–30 minute infrared sauna sessions, 2–5 times per week for the best cumulative mental health benefit5127.
Is it safe? For most people, regular infrared sauna use is safe and well tolerated; however, always consult your healthcare provider if you have medical concerns.
