The Growing Role of Saunas in Integrative Medicine: What Practitioners Are Saying

Twenty years ago, telling your cardiologist you used a sauna for heart health would get you a polite nod and a subject change. Maybe a raised eyebrow. Today, that same conversation might end with your doctor asking which brand you bought.

Something has shifted. Research keeps stacking up. Practitioners who built careers on root-cause medicine have been recommending infrared sauna therapy for decades, and now the peer-reviewed evidence is catching up to what they have been seeing in their clinics.

I want to walk you through what is actually happening in integrative medicine right now, what the research shows, and which practitioners are using saunas in their work. No hype. No miracle cures. Just what we know.

The Old Therapy That Keeps Getting Newer

Sauna is not new. Finns have been doing it for thousands of years. What is new is how seriously the medical research community is taking it.

In 2015, Dr. Jari Laukkanen and his team at the University of Eastern Finland published a study in JAMA Internal Medicine that tracked 2,315 Finnish men over twenty years. The findings turned heads. Men who used a sauna four to seven times per week had a 63 percent lower risk of sudden cardiac death and a 40 percent lower risk of dying from any cause compared to once-a-week users.

Mayo Clinic Proceedings followed up in 2018 with a comprehensive review confirming the cardiovascular benefits and adding more. Better blood pressure regulation. Reduced risk of stroke. Lower rates of dementia. A separate 2018 study in Neurology found that frequent sauna users had a 61 percent lower stroke risk compared to occasional users.

This is the kind of data that makes integrative practitioners pay attention. Honestly, the kind that should make conventional ones pay attention too.

Doctors Are Putting Saunas in Their Practices

The dermatologist down the street probably does not have a sauna in her exam room. But walk into an integrative medicine clinic and there is a decent chance you will see one tucked into a corner or featured in its own treatment room.

Dr. Mikhail Kogan, Medical Director of the GW Center for Integrative Medicine at George Washington University and a founding board member of the American Board of Integrative Medicine, partners with High Tech Health and recommends our saunas to his patients. He has spent his career building bridges between conventional medicine and root-cause approaches. Sauna therapy sits comfortably in that toolkit.

Dr. Sherry Rogers, one of the founding voices in environmental medicine, wrote it bluntly in her book Detoxify or Die. “The best way to get rid of heavy metals and pesticide residues? The Infrared Sauna. My searching led me to a very reputable company, High Tech Health.” She is board certified by both the American Board of Family Practice and the American Board of Environmental Medicine, and she has been recommending sauna therapy in her newsletter and books for over twenty years.

The late Dr. Stephen Sinatra, a board-certified cardiologist and pioneer of integrative cardiology, said something similar. “Clearly, detoxifying ourselves is one of the biggest personal challenges of the 21st century. The sauna that I’m now using is made by High Tech Health in Boulder, Colorado. I use my sauna nearly every day.” He used it as part of his own heart-health protocol and recommended it to patients until his death in 2022.

Dr. Jonathan Wright, Harvard graduate and one of the most respected names in nutritional biochemistry, mentioned our saunas in his Nutrition and Healing newsletter. Dr. David Brownstein, board-certified family practitioner and medical director of the Center for Holistic Medicine, referenced High Tech Health in his book Overcoming Thyroid Disorders.

You see the pattern. These are not influencers chasing trends. They are clinicians who arrived at sauna therapy through evidence and patient outcomes.

What the Research Actually Shows

Dr. Clemens Janssen’s 2016 study in JAMA Psychiatry is one of the more striking findings in this whole area. A single session of whole-body hyperthermia produced antidepressant effects that lasted six weeks in patients with major depressive disorder. Six weeks. From one session. That is not nothing.

The mechanism likely involves the body’s thermoregulatory cooling response, serotonergic pathways, and modulation of inflammatory cytokines. Heat does things to your nervous system and immune signaling that are genuinely fascinating.

That is psychiatry. On the cardiovascular side, the Laukkanen team has published in Mayo Clinic Proceedings, BMC Medicine, JAMA Internal Medicine, and the American Journal of Hypertension over the past decade. Neurology research lives in Age and Ageing and Neurology. The detoxification research has a longer and messier history, but it is there.

These are peer-reviewed journals at major academic medical centers. Independent research, run by university teams, evaluated by editorial boards that have no financial relationship with sauna manufacturers. That distinction matters. There are studies floating around the sauna industry funded by the brands whose products they evaluate, and you should treat those the way you would treat any other paid advertising. The independent research is what changed the conversation in integrative medicine.

Why Practitioners Like Infrared Specifically

The Finnish studies used traditional saunas. Most American integrative clinics use far infrared. Why the switch?

A few reasons. Far infrared heats your body directly instead of heating the air around you. Patients get the therapeutic benefits at lower temperatures, which matters a lot when you are working with someone who has cardiovascular issues, autonomic dysfunction, or simply cannot tolerate 180-degree air. The deeper tissue penetration also seems to help with detoxification protocols, which is why so many environmental medicine practitioners reach for it first.

There is one thing practitioners care about more than most consumers realize. EMF exposure. A sauna full of heating elements sitting inches from your body can generate significant electromagnetic fields. For patients already dealing with environmental sensitivities, that is a real problem. Low-EMF infrared sauna design is not marketing fluff. It is one of the main reasons clinicians choose specific brands. Some of us have been measuring EMF in saunas with handheld meters since before it was cool.

What Conditions Are Practitioners Using Sauna For

I should be careful here. Sauna therapy is not a treatment for these conditions in the way a prescription drug is. It is used as a supportive therapy, an adjunct to a broader care plan. With that said, here is what I see in integrative practices.

Cardiovascular support. The Laukkanen research started this conversation, and the mechanism makes sense. Heat exposure improves endothelial function, reduces arterial stiffness, and supports nitric oxide production. More on that in Infrared Saunas and Blood Pressure.

Detoxification protocols. Heavy metals, persistent organic pollutants, and other fat-soluble toxins do come out in sweat. Not all of them. Not most of them, honestly. But sauna therapy supports the body’s elimination pathways, and combined with proper hydration and binders, it has a place in functional detox work.

Chronic infection recovery. I see this constantly in patients dealing with Lyme disease, mold illness, and chronic inflammatory response syndrome. The heat helps with circulation and immune response, and many patients tolerate it better than aggressive pharmaceutical protocols.

Mood and depression support. The Janssen JAMA Psychiatry findings suggest something real is happening physiologically with heat exposure and mood. The mechanism likely involves serotonergic pathways and inflammatory regulation.

Cognitive health. Finnish research has found significant reductions in dementia and Alzheimer’s risk among frequent sauna users. I unpacked that whole body of research in Can Sauna Use Support Dementia Prevention.

Recovery and performance. Athletes figured this out faster than the medical community did. Heat shock proteins, vascular adaptation, muscle recovery. The mechanisms are well understood. More on that in Heat Shock Proteins and Saunas.

The Catch-Up Effect

There is a well-known principle in medicine that it takes about 17 years for research findings to make their way into routine clinical practice. Sauna therapy is somewhere in the middle of that curve right now.

The integrative and functional medicine community adopted it earlier because their practice model rewards looking at root causes and pulling from a broader evidence base. Conventional cardiology and psychiatry are starting to catch up, slowly. The fact that JAMA Psychiatry, JAMA Internal Medicine, and Mayo Clinic Proceedings are publishing this research means it is no longer fringe.

If your doctor has not mentioned sauna therapy, that is not because the evidence is bad. It is because medical training does not cover thermal therapy in any depth, and most physicians do not have time to read every emerging area outside their specialty. Bring them the studies. Most doctors I know respect that more than wellness anecdotes.

What to Look For If You Are Considering One

This part is practical. If you are thinking about adding sauna therapy to your routine, especially if a practitioner has recommended it, the brand you choose matters more than most people realize.

A few things I tell patients to ask about:

EMF levels, measured at sitting distance with an actual meter. Not marketing claims. Real data.

Heater technology and what wavelengths are produced. Far infrared has the research behind it. Be cautious of saunas claiming to do everything for everyone.

Wood and materials. Cheap saunas use cheap glues that off-gas at temperature. That is the opposite of what you want when the goal is detoxification.

Ventilation. A sealed box full of off-gassing air at 140 degrees is not therapy. Active ventilation matters.

Heater output. Marketing temperature is not the same as actual measurable heat delivered to your body. Calorimetry testing tells you the real story.

Practitioner support. Companies that work directly with clinicians tend to know what their products are actually doing. The team at High Tech Health includes a medical doctor, a chiropractor (hi! that’s me!), a nutritionist, a biochemist, and an electrical engineer and even a psycho therapist. That depth of expertise shows up in the product design.

Where This Is Going

The trajectory is not subtle. More studies. Larger trials. Better journals. Bigger academic medical centers. The question is not whether sauna therapy becomes a standard supportive intervention in integrative medicine. It already is. The real question is when conventional medicine fully gets there.

If you are a practitioner reading this, your patient population is way ahead of you. They are already buying saunas. You can either learn to integrate this tool thoughtfully into your care, or watch them figure it out on Reddit. I would rather be the resource than the obstacle.

If you are considering one for yourself or your clinic, talk to us. We have been doing this longer than anyone, and we are not in a hurry to sell you something you do not need. Request information here or take a look at our infrared sauna lineup when you are ready.

The science is real. The clinical experience is decades deep. And the practitioners who have been quietly using this tool for years are no longer quiet.
