The Science-Backed Benefits of Infrared Saunas

By Dr. Avery Stone

Introduction
Infrared saunas have surged in popularity as an accessible, low-heat alternative to traditional saunas. Beyond their relaxing warmth, a growing body of scientific research suggests they may support cardiovascular health, muscle recovery, mental well-being, metabolic function, and more. Here's what current studies reveal—and how infrared heat therapy may elevate your everyday wellness.

1. How Infrared Saunas Work

Infrared saunas heat the body through infrared light—rather than warming the air—allowing for effective heat absorption at lower ambient temperatures. This radiant heat penetrates deeply into tissues, facilitating a vigorous sweat without the intense heat of a conventional sauna saunasfactorydirect.comWikipedia.

2. Heart Health & Circulation

  • Studies suggest infrared therapy may improve endothelial function, reduce arterial stiffness, and lower blood pressure—effects similar to those achieved through moderate exercise EmbodyWikipedia.

  • Research has linked regular sauna use to lower cardiovascular and all-cause mortality, though further studies specific to infrared are needed mayoclinicproceedings.orgMayo Clinic.

3. Muscle Recovery & Pain Relief

  • Improved circulation from infrared heat helps deliver oxygen and nutrients while removing lactic acid, aiding muscle recovery after exercise. Small studies show notable benefits in muscle soreness relief HealthPopular Science.

  • For individuals with arthritis or chronic pain, infrared sauna sessions have shown short-term improvement in joint stiffness and soreness Popular ScienceWikipedia.

4. Recovery & Athletic Performance

A 2025 study from Frontiers in Sports and Active Living found that while infrared sauna use after training didn’t affect muscle hypertrophy, it did enhance long-term power production, such as improved jump performance Frontiers. The infrared-induced increase in blood flow may help reduce inflammation and accelerate muscle repair Frontiers.

5. Stress Relief & Mental Wellbeing

  • Infrared sessions may help lower cortisol and foster relaxation. Users report improved mood, better sleep, and reduced stress through the meditative environment of a sauna session HealthSpa World Australia.

  • Interestingly, a small clinical trial combining heat therapy with CBT showed significant improvement in depression symptoms—pointing to infrared’s potential as a complementary mental-health tool WIRED.

7. Precautions & Limitations

While promising, research on infrared saunas tends to be limited by small sample sizes and short durations WikipediaMayo Clinic. Moreover, infrared may not be suitable for everyone—pregnant individuals, those with heart conditions, or those taking certain medications should consult a healthcare professional before use HealthNew York Post.
