Infrared Sauna Research Studies You Should Know About
Infrared saunas have gained significant global attention in recent years, not just because they offer a more gentle and efficient form of heat therapy, but because scientific research continues to confirm their benefits. For many people considering purchasing or distributing infrared saunas, understanding the actual studies behind the claims can make a major difference. At WizziSaunas, we often meet customers who come with questions about what research proves and what is simply marketing, and sharing the science behind infrared therapy has become an essential part of our work.
1. Early Medical Research That Sparked Global Interest
Years ago, a customer from Sweden told our team at WizziSaunas that he first learned about infrared therapy through a small medical study conducted in the early 2000s. His father had circulation issues, and a doctor recommended trying low-temperature infrared heat sessions. At that time, infrared saunas were far from mainstream, but the study that inspired his father was based on observations that FIR (far infrared radiation) could gently increase blood flow without placing stress on the heart. The warming effect reached deeper into tissues compared to traditional saunas, which rely on heating the air around the body.
When he shared this story, we revisited those early research papers. Many came from Japan, where infrared therapy was used clinically to support patients recovering from fatigue, injury, and cardiovascular problems. These foundational studies helped shape the modern understanding of why infrared saunas are so effective, particularly for people who cannot tolerate the extreme heat of conventional saunas.
2. Research on Cardiovascular Health and Infrared Therapy
One of the most referenced studies in infrared sauna discussions is a series of clinical trials conducted by Japanese cardiologist Dr. T. Tei. These studies explored how far-infrared saunas affect patients with chronic heart failure. Instead of focusing on anecdotal evidence, these trials documented measurable improvements, including reduced blood pressure, increased vascular function, and enhanced overall circulation.
What makes these studies important for buyers today is their emphasis on low-temperature therapy, typically at 45–60°C. This aligns strongly with the design philosophy of WizziSaunas, where we prioritize infrared emitters that deliver strong therapeutic wavelengths without overheating the environment. Many distributors also tell us that customers prefer this type of sauna because it feels safer and more comfortable for beginners, particularly seniors.
3. Research on Detoxification and Heavy Metals
A surprising area of study involves detoxification. While the term is often used loosely in marketing, research conducted in Canada and Finland examined whether infrared sauna sweating actually helps remove harmful substances from the body. These studies collected sweat samples from participants and analyzed levels of heavy metals such as lead, mercury, and cadmium. The results indicated that sweat produced during infrared sessions contained higher concentrations of certain toxins compared to sweat from traditional sauna use or exercise.
At WizziSaunas, we’ve heard many personal stories from users who report consistent improvements in skin clarity, sleep quality, and overall wellbeing after regular infrared sessions. Although these personal accounts aren’t scientific studies, they support the practical implications of the research: the body responds differently to deep-penetrating infrared heat, and sweating becomes more efficient at eliminating waste.
4. Studies on Pain Relief and Muscle Recovery
Infrared therapy has also been tested extensively in sports medicine. Several studies published in physical therapy journals describe how FIR exposure reduces inflammation, accelerates muscle recovery, and helps with chronic pain conditions like arthritis. A distributor from Colorado told us about a cyclist who purchased one of our infrared saunas after reading a clinical study showing that FIR can improve recovery between training sessions. He used his sauna every evening during competition season and claimed that the gentle heat helped him sleep better and recover faster.
This kind of feedback aligns with scientific findings that infrared wavelengths enhance blood flow and relax muscle tension, making it a powerful tool for athletes, physical therapists, and wellness centers.
Conclusion: Why These Studies Matter for Your Infrared Sauna Choice
Scientific research plays an important role in guiding consumers and distributors toward safer and more effective sauna solutions. The studies mentioned above show that infrared saunas are not just a wellness trend—they have real therapeutic potential backed by decades of clinical observation. At WizziSaunas,infrared sauna research studies, we design our infrared sauna models based on these proven principles, ensuring that every unit supports cardiovascular health, detoxification, pain relief, and relaxation in a way that aligns with modern research.
