When it comes to recovery tools that promise big health returns, infrared saunas tend to top the list. Once a niche wellness tool, infrared saunas are now gaining traction with athletes, biohackers, and recovery seekers alike.
But what’s hype—and what actually holds up?
This post breaks it down. We’ve sifted through the research and translated it into real-world benefits. Whether you’re chasing faster recovery, better sleep, or long-term health, here’s what the science actually supports.
Why Infrared Saunas Are Gaining Ground
Infrared saunas aren’t like traditional saunas. Instead of heating the air around you, they use invisible infrared light to directly warm your body. That makes them more comfortable for many people, with lower ambient temperatures (usually around 110–140°F).
There are different types:
- Far Infrared (FIR): The most common type. Penetrates skin deeply and has the most research behind it.
- Mid Infrared (MIR): Targets soft tissue, joints, and muscles. Often marketed for circulation and pain relief.
- Near Infrared (NIR): Targets the skin's surface and may aid wound healing and collagen production.
- Full-Spectrum: Combines near, mid, and far infrared for broader benefits.
More people are turning to infrared saunas as a gentler alternative to traditional steam or dry saunas—and the science is starting to back them up.
Want a full breakdown of infrared vs traditional saunas? Check out our comparison guide.
1. Boosting Cardiovascular Function
Infrared saunas mimic the effects of light aerobic exercise—and your body responds the same way.
When your core temperature rises, your heart rate increases and breathing deepens. This simulates the cardiovascular demand of a brisk walk, triggering blood vessel dilation and improving overall circulation.
Clinical research—particularly on far infrared therapy like Waon therapy—shows improved vascular function and better blood flow, even in patients with chronic heart conditions. And while most long-term studies focus on traditional sauna use, the mechanism is the same: raise your internal temperature, elevate heart rate, and stimulate healthy blood flow.
The result? A cardiovascular workout without physical strain—making it ideal for people recovering from injury, managing chronic conditions, or simply looking to support heart health without overexertion.
2. Detoxification Through Sweat
Infrared saunas help your body do what it was designed to do: sweat.
But this isn’t just water weight. Your sweat contains trace amounts of heavy metals, BPA, and other toxic compounds that build up over time. That makes regular sauna use a practical, science-backed way to support detoxification.
Far infrared therapy has been shown to promote the elimination of pollutants like mercury, lead, and phthalates—chemicals found in plastics and industrial products. Unlike traditional saunas, infrared heat penetrates more deeply and can produce a heavier sweat without pushing your body into extreme temperatures.
Translation: You sweat more, without feeling like you're dying in a furnace. And that sweat might be doing more than cooling you down.
3. Chronic Pain and Muscle Recovery
Infrared saunas do more than just warm your skin—they get under it.
Infrared heat penetrates deep into tissue, stimulating blood flow and activating the systems that calm nerves, ease pain, and accelerate healing.
Studies show infrared therapy reduces symptoms of chronic fatigue, fibromyalgia, and muscle pain. That’s because heat improves blood flow, lowers inflammation, and activates your parasympathetic nervous system—the part responsible for rest and recovery.
Sauna sessions can help flush out metabolic waste, deliver fresh oxygen to your muscles, and promote deep tissue healing. It's a passive way to give your body the physiological cues it needs to start feeling better.
For athletes, the benefit is clear: faster recovery and less soreness.
4. Skin Health and Anti-Aging Potential
Infrared saunas can do more than make you sweat—they may also support clearer, healthier-looking skin.
By increasing circulation and stimulating sweat, infrared heat helps bring oxygen and nutrients to the surface while carrying away waste and impurities. This process may support better skin tone, fewer breakouts, and enhanced collagen production over time.
Animal studies have shown that far infrared exposure improves microcirculation in the skin, while small-scale human studies using infrared-emitting patches and facial devices report improvements in skin oxygenation, temperature regulation, and collagen remodeling.
Infrared sauna research in humans is still developing, but the early signs are promising. In short, better blood flow and deep, purifying sweat could mean fresher, firmer, and more resilient skin.
5. Mental Health, Mood, and Relaxation
Heat doesn’t just relax your muscles. It helps calm your mind, too.
Infrared sauna therapy has been linked to reduced symptoms of mild depression, burnout, and chronic fatigue. One clinical study even showed that a single full-body session significantly improved mood in patients with major depressive disorder.
But what’s actually happening under the surface?
It’s a mix of brain chemistry and nervous system response. Gentle heat can trigger feel-good neurotransmitters, lower stress hormones, and shift your body into rest-and-recover mode.
The result: more calm, more clarity, less stress.
6. Inflammation and Oxidative Stress
Inflammation is a root cause of everything from joint pain to heart disease. Regular sauna use may help bring it down—and infrared heat could offer a lower-temp way to do it consistently.
Most of the hard data here comes from studies on Finnish dry saunas, but the results are promising: reductions in C-reactive protein (an inflammation marker) and oxidative stress levels (which contribute to aging and chronic disease).
Because infrared saunas use similar heat-based mechanisms—like raising core body temperature and increasing blood flow—it’s reasonable to expect similar effects.
7. Weight Loss and Metabolic Support
Infrared saunas aren’t a weight loss gimmick—but they have real potential to support your metabolism.
Remember that raising your core temperature and heart rate mimics light cardio, which increases caloric burn without physical strain. That means passive energy expenditure—especially useful for rest days or injury recovery.
The deeper impact?
Repeated infrared sessions may lower inflammation and improve insulin sensitivity—two key players in metabolic health. One study even found infrared use helped reduce oxidative stress in people with type 2 diabetes.
No, it’s not a fat-melting miracle. But as part of a bigger wellness plan, it absolutely pulls its weight.
Are Infrared Saunas Worth It?
Infrared sauna therapy offers real, measurable benefits—especially for recovery, circulation, inflammation, and mental well-being.
Early research shows promising results across several areas: improved cardiovascular function, deeper detox through sweat, pain relief, clearer skin, and even better mood. While most long-term data still comes from traditional sauna studies, infrared saunas use the same core mechanism: gentle heat that raises core body temperature and increases blood flow.
What sets infrared apart is its accessibility. Lower temperatures and deeper tissue penetration make it easier to use consistently—so you can actually stick with the habit and see results over time.
The science is still catching up, but the benefits already speak for themselves.

FAQ: Infrared Sauna Benefits & Usage
What are the benefits of infrared sauna?
Infrared sauna therapy has been linked to improved heart health, detoxification, reduced inflammation, better skin tone, enhanced muscle recovery, and stress relief.
How long to see benefits of infrared sauna?
Some benefits like relaxation are felt right away. Others—like improved circulation, clearer skin, or inflammation reduction—take several weeks of regular use.
How often should you use an infrared sauna?
Most studies support using infrared saunas 3–5 times per week for 15–30 minutes. Dr. Rhonda Patrick, a biomedical researcher known for her work on sauna science, suggests aiming for 4–7 weekly sessions to get the longevity and cardiovascular benefits.
Are infrared saunas safe?
Yes, for most people. They operate at lower temperatures than traditional saunas, which many find more tolerable. Stay hydrated and consult your doctor if you have underlying health conditions.
Do infrared saunas really detox your body?
Studies show infrared-induced sweat can help eliminate environmental toxins like heavy metals and persistent organic pollutants.
Infrared sauna benefits vs regular sauna—which is better?
It depends. Infrared saunas heat the body more directly and at lower temperatures. Both types offer health benefits, but infrared may be more comfortable and accessible for frequent use.
