The sauna debate has been going on for years: infrared vs. traditional, steam vs. dry heat, low temperature vs. high heat. Both have loyal advocates, both have real science behind them, and both deliver genuine wellness benefits. But they are not the same thing — and for many patients, one is meaningfully better suited to their goals than the other.
At the Institute for Ageless Living in Longmont, CO, we offer physician-guided Infrared Sauna sessions as part of our integrated wellness program. This guide gives you the full, honest comparison — how each type works, what the research says, and how to decide which is the right fit for you.

How Each Type of Sauna Works: The Core Difference
Traditional Sauna (Finnish / Steam / Dry Heat)
A traditional sauna heats the air around you using a wood-burning stove (kiuas), electric heater, or steam generator. The temperature in a traditional sauna typically ranges from 170–200°F (77–93°C) — hot enough that most people can only tolerate 10–20 minutes at a time.
Your body responds to the hot air by sweating and increasing heart rate — a passive cardiovascular workout that has been linked to a wide range of health benefits in research spanning decades, particularly the large Finnish cohort studies. Heat penetrates the body primarily through surface-level convection and conduction.
Infrared Sauna
An infrared sauna heats your body directly using infrared light — electromagnetic radiation in the near-, mid-, and far-infrared wavelengths — rather than heating the surrounding air first. The cabin temperature in an infrared sauna typically ranges from 110–140°F (43–60°C), significantly lower than a traditional sauna.
Because infrared wavelengths penetrate up to 1.5 inches (3–4 cm) below the skin surface, the body's core temperature rises without requiring the extreme ambient heat of a traditional sauna. This produces a comparable sweat response — and comparable cardiovascular activation — at a temperature many people find far more comfortable to breathe in.
At the Institute for Ageless Living, our full spectrum infrared cabins use near-, mid-, and far-infrared wavelengths simultaneously, maximizing the range of tissue effects from a single session.
Head-to-Head Comparison: Infrared vs. Traditional Sauna
Temperature and Breathability
Traditional sauna: 170–200°F ambient air. Hot, dry (or steam-humid) air can feel suffocating for some users, particularly those with respiratory sensitivities, asthma, or heat intolerance.
Infrared sauna: 110–140°F ambient air. The air itself is warm but comfortable to breathe. Most people — including those who find traditional saunas overwhelming — tolerate infrared sessions easily for 30–45 minutes.
Depth of Heat Penetration
Traditional sauna: Heat penetrates the skin surface through convection. The core temperature rises because the body is enveloped in hot air, not because heat travels deeply into tissue.
Infrared sauna: Infrared light absorbs directly into water molecules and chromophores in tissue, penetrating up to 1.5 inches below the skin. This deeper tissue warming is one reason infrared saunas are associated with more pronounced effects on muscle recovery, joint pain, and detoxification compared to surface-level heat.
Sweat Volume and Detoxification
Both types of sauna produce significant sweating. However, infrared sauna sessions are associated with a higher sweat output per degree of ambient temperature — meaning you sweat more at a lower air temperature. Some research suggests infrared-induced sweat has a higher concentration of heavy metals and toxins compared to sweat from traditional saunas, though the clinical significance of this finding is still being studied.
For patients pursuing detoxification goals — particularly heavy metal reduction, a common wellness concern in Colorado given environmental exposure patterns — infrared sauna is generally the preferred modality.
Cardiovascular Effects
This is where traditional sauna has the strongest body of evidence. The long-running Finnish studies (Laukkanen et al.) found that regular traditional sauna use — four or more times per week — was associated with significantly reduced risk of cardiovascular events, sudden cardiac death, and all-cause mortality.
Infrared sauna research is newer and smaller in scale, but early findings support comparable cardiovascular benefits: improved endothelial function, reduced arterial stiffness, and modest blood pressure reduction. A 2024 systematic review found that infrared sauna sessions raise heart rate and metabolic activity similarly to moderate-intensity exercise. For patients seeking cardiovascular conditioning without high ambient heat, infrared sauna is a clinically reasonable alternative.
Pain Relief and Muscle Recovery
Traditional sauna: Well-established for post-exercise muscle recovery, reducing delayed-onset muscle soreness (DOMS), and relieving tension. The high heat causes significant vasodilation.
Infrared sauna: The deeper tissue penetration of infrared wavelengths may provide more targeted pain relief for joint conditions, fibromyalgia, and chronic back pain. Several studies have found meaningful improvements in pain scores and quality of life for fibromyalgia patients using regular infrared sauna therapy. For patients in Longmont dealing with arthritis, post-athletic soreness, or musculoskeletal pain, infrared sauna is often the more therapeutically targeted option.
Skin Benefits
Traditional sauna: Promotes circulation and sweating, which can benefit skin clarity over time. High heat and steam can be irritating for sensitive skin types or conditions like rosacea.
Infrared sauna: Near-infrared wavelengths specifically stimulate collagen production and fibroblast activity in the dermis. This makes infrared sauna a genuine complement to aesthetic treatments — patients undergoing RF Microneedling or CO2 Laser Resurfacing may find that regular infrared sessions support overall skin quality between treatments.
Session Length and Frequency
Traditional sauna: 8–20 minutes per round, typically with cool-down breaks. High heat requires shorter sessions.
Infrared sauna: 30–45 minutes per session, typically once per day or several times per week. The lower ambient temperature allows longer, more comfortable sessions.
Accessibility and Tolerance
Traditional saunas require tolerance for intense heat, which excludes many older adults, those with heat sensitivity, cardiovascular conditions, or respiratory issues from using them safely.
Infrared saunas are significantly more accessible — suitable for a broader range of ages and health profiles, including many patients who find traditional sauna heat prohibitive. At the Institute for Ageless Living, patients from their 20s through their 70s use our infrared sauna as part of their regular wellness plans.
What Does the Research Actually Say?
It is worth being direct: traditional sauna has more published long-term data behind it, primarily due to the Finnish research tradition. The cardiovascular and mortality data for traditional sauna use is genuinely compelling.
Infrared sauna research is growing but younger. The evidence for pain relief, particularly in fibromyalgia and rheumatoid arthritis, is reasonably strong. The detoxification, skin, and cardiovascular data is promising but still accumulating.
The National Institutes of Health and peer-reviewed literature support both modalities as beneficial wellness interventions when used appropriately and consistently. Neither is a medical treatment for diagnosed conditions, but both can meaningfully support preventive health and recovery goals when integrated into a physician-guided wellness plan — which is exactly the context in which we use them at the Institute for Ageless Living.
Which Is Better for Specific Goals?
For cardiovascular health
Both deliver cardiovascular benefits. Traditional sauna has the longest evidence base. Infrared sauna is a valid alternative for patients who cannot tolerate high ambient heat. Recommendation: either, based on tolerance.
For muscle recovery and athletic performance
Recommendation: infrared sauna, for its deeper tissue penetration and longer comfortable session lengths. Well-suited for athletes in the Boulder/Longmont area who train regularly.
For chronic pain — joints, fibromyalgia, back pain
Recommendation: infrared sauna. The deeper heat penetration and targeted near-infrared wavelengths have the stronger evidence base for musculoskeletal pain relief.
For detoxification
Recommendation: infrared sauna. Higher toxin concentration in sweat and better tolerance for longer sessions gives it an edge for patients with detox goals.
For skin quality
Recommendation: infrared sauna. Near-infrared wavelengths specifically stimulate collagen production. Complements aesthetic treatments at the Institute for Ageless Living.
For the traditional sauna experience and cultural practice
Recommendation: traditional sauna. The ritual, the intense heat, the social dimension — these are genuinely valuable and not replicated by infrared.
For first-time users, older adults, or heat-sensitive patients
Recommendation: infrared sauna. More accessible, more comfortable, lower barrier to consistent use.
Can You Combine Infrared Sauna with Other Treatments?
At the Institute for Ageless Living, infrared sauna sessions are often paired with other wellness and recovery modalities. Common combinations include:
- Cryotherapy immediately after infrared sauna: the contrast of deep heat followed by cold therapy activates powerful vascular responses that may amplify recovery and metabolic benefits
- Red Light Therapy: combining near-infrared sauna wavelengths with targeted red light LED therapy creates synergistic effects on collagen production, inflammation reduction, and cellular energy
- IV Therapy: rehydration and nutrient replenishment following a sauna session restores what sweating removes and supports the detoxification process
- Hyperbaric Oxygen Therapy: pairing cellular oxygenation from HBOT with the cardiovascular activation of infrared sauna creates a broad-based recovery and anti-aging protocol
Our physician, Dr. Kirk E. Mitchell, MD, designs combination protocols based on your specific goals, health profile, and the evidence base for each pairing. Not every combination is appropriate for every patient — which is why physician oversight matters.
FAQs: Infrared Sauna vs. Traditional Sauna
Is infrared sauna actually effective, or is it just a wellness trend?
Infrared sauna has a growing body of clinical research supporting real benefits for pain relief, cardiovascular health, skin quality, and recovery. It is not simply a trend. That said, like any wellness modality, results depend on consistent use and are best achieved as part of a broader health plan rather than as a standalone fix.
Can I use infrared sauna if I have high blood pressure?
Many patients with mild, controlled hypertension use infrared sauna safely — and some research suggests regular use may modestly reduce blood pressure over time. However, uncontrolled hypertension is a contraindication. Always disclose your full medical history during your consultation, and obtain clearance from your primary care provider if cardiovascular conditions are present.
How often should I use an infrared sauna?
For general wellness maintenance, two to three sessions per week over six to eight weeks is the standard protocol supported by research. Athletes or patients with specific recovery goals may benefit from more frequent sessions. After the initial phase, one weekly session can maintain cardiovascular and musculoskeletal benefits.
Is an infrared sauna better than a steam room?
Steam rooms (wet heat, 100–120°F, near 100% humidity) offer respiratory benefits and skin hydration, but do not produce the deep tissue heat or same cardiovascular activation as infrared or traditional dry saunas. For most of the goals patients come to us with — recovery, detox, pain relief, skin support — infrared sauna delivers more targeted, evidence-backed benefits than a steam room.
What altitude considerations apply to infrared sauna in Longmont, CO?
Longmont sits at approximately 5,000 feet elevation. Colorado's dry, high-altitude climate means fluid loss during sauna sessions is higher than at sea level, and cardiovascular responses can be slightly more pronounced. Our team provides altitude-specific hydration guidance and monitors new patients more closely during initial sessions.
