There’s more happening in the sauna than simply getting warm.
When your body is exposed to heat, circulation increases, heart rate rises, blood vessels respond, and sweating helps the body manage the increase in temperature.
What becomes especially interesting is what researchers have observed with regular sauna use over time.
Studies have associated frequent sauna bathing with:
• healthier cardiovascular function
• improved circulation and vascular response
• support for healthy blood pressure
• physical recovery after exercise
• a lower risk of cardiovascular mortality in long-term observational research
The strongest long-term research comes from Finnish sauna studies, where more frequent sauna use has been associated with better cardiovascular outcomes. Controlled research has also found that adding regular sauna sessions to an exercise routine can improve certain measures of cardiovascular health.
There is still more to learn, and sauna is one part of a much bigger picture that includes movement, nutrition, sleep, stress management, and appropriate medical care.
At Glow, we love thermotherapy for the experience itself - warmth, stillness, contrast, and time to slow the pace - with an increasingly interesting body of research behind regular heat exposure.
