Infrared Sauna & Heart Health: What the Evidence Says
Full-spectrum infrared saunas don’t just feel good, research suggests they may support cardiovascular and circulation health through controlled heat exposure.
🫀 What happens in the body:
Infrared sauna use gently raises core body temperature, triggering vasodilation (widening of blood vessels), increased heart rate, and improved blood flow, responses similar to low-intensity cardiovascular exercise.
📊 Clinical evidence reports:
✔️ Improved endothelial function (health of blood vessel lining)
✔️ Enhanced circulation and blood flow during and after sessions
✔️ Reductions in resting blood pressure in some populations with regular use
✔️ Improved arterial compliance (vessel flexibility)
✔️ Positive cardiovascular adaptations when used consistently over time
Large observational studies have also found that frequent sauna use is associated with lower cardiovascular and all-cause mortality, suggesting long-term heart health benefits when sauna use is part of a healthy lifestyle.
Why full-spectrum matters:
Full-spectrum infrared delivers near, mid, and far infrared wavelengths, providing deeper tissue warming and a more comprehensive heat response compared to single-wavelength systems.
