Infra-Red Sauna, Red Light & Recovery: What the Science Really Tell Us?

But how much of the hype is actually supported by science? In this episode, we sit down with Joie Risk, Managing Director for Sunlighten across the UK, Ireland and Europe, to explore where infrared sauna and red and near-infrared light therapy genuinely fit within modern recovery and health optimisation. Joie shares her perspective on the evolution of infrared sauna, how the technology has developed, and what actually happens physiologically when we are exposed to heat. We explore the differences between near, mid and far infrared, how infrared sauna compares with traditional Finnish sauna, and whether the benefits come primarily from infrared wavelengths, increased core temperature, or a combination of both. A key focus of the conversation is heat exposure and recovery. We discuss the evidence around circulation, heat-shock proteins, soreness, sleep and tissue recovery, as well as the idea that “heat is the new cardio”. We also explore whether there is an optimal dose of sauna, how temperature, duration and frequency should be considered, and whether timing matters around exercise. The conversation also looks at how men and women may respond differently to heat, including the influence of hormonal fluctuations, the menstrual cycle, perimenopause and menopause. Joie explains why heat tolerance and adaptation may vary between individuals and why sauna protocols shouldn't necessarily be one-size-fits-all. Finally, we compare heat and cold exposure, discuss the potential role of contrast therapy, and consider where infrared sauna belongs within a wider recovery pyramid alongside sleep, exercise, nutrition and stress management. The key message? Sauna and light therapy may have a role in recovery and healthspan, but the most important question isn't simply whether they “work”. It's how, when, for whom, and at what dose they should be used as part of a broader evidence-based approach to health and recovery. 🎙️ In This Episode, We Cover • How infrared sauna has evolved from spa treatment to recovery and longevity tool • What actually happens physiologically during infrared sauna • Near, mid and far infrared explained • Infrared sauna vs traditional Finnish sauna • Whether “heat is the new cardio” • Heat exposure, recovery, circulation and sleep • Heat-shock proteins and physiological adaptation • How long, how hot and how often to use a sauna • The best timing for sauna around exercise • Sex differences in heat tolerance and adaptation • Heat exposure during the menstrual cycle, perimenopause and menopause • What red and near-infrared light therapy actually does • Photobiomodulation and its potential applications • Where the evidence for red light therapy is strongest • Heat vs cold exposure and the role of contrast therapy • Where sauna belongs within an evidence-based recovery strategy • Common mistakes with temperature, hydration, duration and frequency • How to approach sauna if you're completely new to it 🎯 Who This Episode Is For • Athletes and active individuals interested in recovery • People exploring sauna and heat therapy for health and wellbeing • Anyone interested in longevity and healthspan • People curious about red and near-infrared light therapy • Those looking to optimise sleep, recovery and stress management • Clinicians, coaches and practitioners interested in emerging recovery technologies 🎙️ Powered by Mayfair Health At Mayfair Health, we specialise in recovery, performance and proactive wellness.
