I get asked quite regularly about the research behind infrared saunas and red light therapy.
I'll give you the short version. The long version is sitting on my desk, and honestly, I'd rather have a conversation with you about it than give you pages of studies to read through.
Research from long-term Finnish studies found that spending just 20 minutes in an infrared sauna 2–3 times per week was associated with a 27% lower risk of fatal heart disease. For those using a sauna 4 or more times per week, that figure increased to a remarkable 57% lower risk of fatal heart disease and a 41% reduction in all-cause mortality.
These weren't small studies, and the findings have been replicated over time.
As for red light therapy, what was once considered alternative or fringe has become increasingly supported by scientific evidence. Research now shows it can help support cellular function, reduce inflammation, encourage tissue repair, and improve circulation through biological pathways that are now well documented.
The science is continually evolving, but one thing is becoming increasingly clear: giving our bodies the right environment to recover, repair, and regulate themselves can have profound effects on our overall wellbeing.
If you've been curious about infrared sauna or colour light therapy and would like to know more, feel free to reach out or come in for a chat. I'm always happy to discuss the research and whether these therapies might be a good fit for you.
