What Is an Infrared Sauna — and Why Is It Different?

If you've ever stepped out of a traditional steam sauna gasping from the 190°F heat, you already understand the barrier that keeps some people from making sauna therapy part of their routine. Infrared saunas solve that problem without sacrificing the benefits.

Where a conventional sauna heats the air around you — forcing your body to absorb warmth indirectly — an infrared sauna uses far-infrared light wavelengths that penetrate directly into skin, fat, and muscle tissue, typically 3 to 4 centimeters deep. The cabin operates at a gentler 120°F to 140°F, yet the physiological response is every bit as robust. Your core temperature rises, your cardiovascular system vasodilates, and you produce a deep, sustained sweat that continues long after you step out.

The result is a therapy that feels more tolerable for most people, is accessible to a wider range of fitness levels and health backgrounds, and delivers a breadth of documented benefits that researchers are only beginning to fully map.

At Club Contour Studios' Wellness Lounge in Tarzana, infrared sauna is one of the cornerstone recovery and wellness therapies — available on its own or as part of a contrast therapy circuit alongside cold plunge and contrast therapy.

The Science Behind Infrared Sauna: What the Research Actually Shows

Sauna therapy has accumulated one of the strongest evidence bases in the wellness world over the past decade, and the science published in 2025 and 2026 has only reinforced that standing. Here's what peer-reviewed research currently supports.

Cardiovascular Health

A 2024 comprehensive review by Laukkanen and Kunutsor — two of the most published researchers in this field — confirmed that regular passive heat therapy is associated with improved vascular function, reduced arterial stiffness, lower resting blood pressure, and meaningfully decreased risk of cardiovascular disease, stroke, and dementia. A 2025 paper in Frontiers in Cardiovascular Medicine went further, describing sauna therapy as a "novel management approach" for cardiovascular health — language that underscores how seriously the medical community now takes this data.

The mechanism is straightforward: as your core temperature rises during an infrared sauna session, your heart rate increases (mimicking the effect of moderate aerobic exercise) and blood vessels dilate throughout the body, improving circulation and reducing the pressure your heart works against.

Muscle Recovery and Athletic Performance

A 2025 study from the University of Jyväskylä, published in Frontiers in Sports and Active Living, found that post-exercise infrared sauna sessions meaningfully improved recovery of neuromuscular performance and reduced muscle soreness following resistance training. The deep tissue penetration of far-infrared heat is thought to accelerate the clearance of metabolic byproducts, reduce inflammation, and increase blood flow to fatigued muscle tissue.

Whether you train at a gym, run on the trails above Tarzana, or simply carry the physical demands of a full workday, infrared sauna offers a passive route to faster, more complete recovery.

Mental Wellbeing and Stress Relief

A groundbreaking 2025 clinical trial at UCSF found that whole-body heat therapy combined with cognitive behavioral therapy produced clinically meaningful reductions in major depressive disorder symptoms in more than 85% of participants. While the UCSF trial used a controlled clinical setting, the underlying mechanism — the release of endorphins, the elevation of core body temperature mimicking the physiological state of sleep onset, and the forced physiological quieting of the stress response — applies equally to wellness-grade infrared sauna use.

Most regular users report noticeable improvements in sleep quality and stress resilience within two to four weeks of consistent sessions, which aligns with what the research predicts.

Skin Health and Sweating

The deep, sustained sweat triggered by far-infrared heat differs from the surface-level perspiration of exercise. Because the heat penetrates several centimeters into subcutaneous tissue, the sweat response originates deeper, helping to flush pores and support healthy skin turnover. Regular infrared sauna users commonly report improvements in skin clarity, tone, and texture over time — benefits that complement other aesthetic and wellness services at Club Contour Studios.

Cellular Health and Longevity

Research published in early 2026 highlights the hormetic role of infrared heat — the concept that a controlled thermal stress triggers a protective biological adaptation. When core temperature rises during a sauna session, the body produces Heat Shock Proteins (HSPs): molecular chaperones that repair damaged proteins and help prevent the protein misfolding associated with aging and neurodegenerative disease. This is one reason why sauna use has been linked in long-term population studies to reduced rates of cognitive decline and all-cause mortality in frequent users.

Who Can Benefit Most from Infrared Sauna?

Infrared sauna is genuinely broad in its appeal. At Club Contour Studios' Wellness Lounge in Tarzana, the therapy is popular across a wide range of goals and backgrounds:

• Active recovery: Athletes and fitness enthusiasts using infrared sauna to accelerate muscle repair and reduce post-training soreness.
• Stress and sleep management: Professionals, parents, and anyone dealing with the physiological burden of chronic stress who want a non-pharmaceutical route to better sleep and a quieter nervous system.
• Longevity and healthspan: Those aligned with proactive, preventive health who want to support cardiovascular function, cellular repair, and healthy aging — often pairing infrared sauna with services from Contour Medical Clinic.
• Skin and aesthetic goals: People looking to support skin clarity and a healthy glow as part of a broader self-care routine.
• Those who find traditional saunas too intense: Because infrared saunas operate at significantly lower ambient temperatures, they are often accessible to people who cannot tolerate a 190°F conventional sauna environment.

What to Expect During Your Infrared Sauna Session at Club Contour Studios

The Wellness Lounge at Club Contour Studios is designed to feel like a genuine retreat — not a gym amenity or an afterthought. When you book an infrared sauna session in Tarzana with us, here's what the experience looks like:

You'll arrive and have time to settle in before your session begins. The sauna cabin is pre-heated and ready when you enter. Sessions typically run 30 to 45 minutes. The temperature feels warm and enveloping rather than sharp or suffocating — most first-timers are pleasantly surprised by how manageable it is, even as they begin to sweat deeply.

Towels and water are available. You're encouraged to hydrate before, during, and after. After your session, you'll notice the warmth and relaxation continuing for some time — the post-session glow is a hallmark of good infrared sauna use.

Our team can also guide you through pairing infrared sauna with a cold plunge or contrast therapy circuit, which significantly amplifies the circulatory and recovery benefits of both.

How to Get the Most Out of Every Session

Infrared sauna is straightforward, but a few habits separate a good session from a great one.

Before Your Session

Hydrate well — ideally drinking 16 to 24 oz of water in the hour before you arrive. Avoid heavy meals in the two hours prior; your body will thank you. Arrive without lotion or heavy skin products on, as they can interfere with the sweating process and may cause skin irritation when heated.

During Your Session

Settle in and allow yourself to relax fully. The temptation is to scroll your phone — resist it. The parasympathetic benefits of infrared sauna are amplified when you allow your nervous system to actually downregulate. Breathe slowly and deeply. If the heat ever feels overwhelming, step out briefly, rehydrate, and re-enter when you're ready.

After Your Session

Give yourself time to cool down gradually rather than rushing back into full activity. A lukewarm shower (or a cold plunge, if you're ready for contrast therapy) works well. Continue hydrating — you've lost meaningful fluid through sweat and replacing it with water or an electrolyte drink matters for how you feel in the hours that follow.

How Often Should You Use an Infrared Sauna?

Research suggests three to four sessions per week as the threshold where measurable health benefits begin to compound. At this frequency, most people report subjective improvements in sleep, stress, and muscle recovery within two to four weeks. The cardiovascular and cellular adaptations documented in long-term studies typically require eight to twelve weeks of consistent use at that same frequency.

That said, even one or two sessions per week offers real value — especially for recovery, relaxation, and skin health. The most important variable is consistency over time rather than any single session's duration or intensity.

If you're new to infrared sauna, starting with 20-minute sessions and building toward 30–45 minutes over your first few visits is a sensible approach.

Combining Infrared Sauna with Other Wellness Therapies

One of the unique advantages of the Wellness Lounge at Club Contour Studios is that infrared sauna doesn't have to exist in isolation. Some of the most impactful wellness protocols in the San Fernando Valley combine infrared sauna with other thermal therapies available at the studio.

Contrast Therapy (Heat + Cold): Alternating between the infrared sauna and the cold plunge — a practice called contrast therapy — produces a dramatic vascular pumping effect. As your blood vessels dilate in the heat and then constrict rapidly in the cold, circulation is forced through capillary beds that rarely see full perfusion during normal daily activity. The result is accelerated recovery, reduced inflammation, an endorphin surge, and a state of mental clarity and energy that users describe as one of the most effective natural performance interventions they've experienced. Read more about this in our guide to the ultimate wellness recovery experience in Tarzana.

Steam Ozone Pod: The Wellness Lounge also features a steam ozone pod — a distinct experience from infrared sauna that uses moist heat and ozone infusion. Some members cycle between the two depending on their goals for a given session.

Our team is happy to help you design a protocol that matches your schedule, recovery goals, and experience level.

Is Infrared Sauna Safe? Important Considerations

For most healthy adults, infrared sauna is very well tolerated and safe. That said, there are situations where medical clearance is appropriate before beginning:

• Pregnancy: The American College of Obstetricians and Gynecologists advises against sauna use during pregnancy due to the risk of elevating core body temperature. Wait until after delivery and consult your physician before resuming use.
• Unstable cardiovascular conditions: Active heart failure, recent stroke, or severe hypotension are contraindications. Anyone with a diagnosed cardiovascular condition should speak with their physician before using infrared sauna.
• Implanted medical devices: Pacemakers, implantable cardioverter-defibrillators (ICDs), cochlear implants, and drug delivery implants may be affected by heat. Device manufacturer approval and physician sign-off are required.
• Active fever or acute illness: Skip your session if you're unwell — your body is already under thermal stress.
• Transdermal medication patches: Remove patches (fentanyl, nicotine, hormones, lidocaine) before entering the sauna.
• Children: Children's bodies heat up faster and less predictably than adults. We recommend consulting a pediatrician before any sauna use for minors.

If you have any questions about whether infrared sauna is appropriate for your situation, our Wellness Lounge team is here to help — and for members who are also working with Contour Medical Clinic, our providers can offer guidance as part of your overall wellness plan.

Frequently Asked Questions About Infrared Sauna in Tarzana

How is infrared sauna different from a regular sauna?

A traditional sauna heats the air in the room to 185–200°F, and your body absorbs that heat from the environment. An infrared sauna uses far-infrared light wavelengths to heat your body directly — penetrating 3 to 4 centimeters into tissue — at a much lower cabin temperature of 120–140°F. The deep tissue penetration makes the physiological response (core temperature rise, sweating, cardiovascular stimulation) similar to or greater than a traditional sauna, but the experience is significantly more tolerable for most people.

What should I wear in the infrared sauna?

Light, loose-fitting clothes (like athletic shorts and a tank top) or a swimsuit work well. A towel to sit on is recommended. Some people prefer minimal clothing to maximize skin exposure to the infrared light.

How long should my session be?

Most people find 30 to 45 minutes to be ideal for a full session. If you're new to infrared sauna, starting with 20-minute sessions and building up gradually is a smart approach. Listen to your body — if you feel lightheaded or overly uncomfortable at any point, exit the sauna, hydrate, and rest.

Will I sweat a lot?

Yes — infrared sauna is specifically designed to induce a deep, sustained sweat. This is part of its value. Plan to towel off and shower after your session, and drink plenty of water before and after.

Can I use infrared sauna every day?

Daily use is generally well-tolerated for healthy adults, though most research suggests the sweet spot for measurable health benefits is 3–4 sessions per week. Starting with every other day and adjusting based on how you feel and recover is a practical approach for new users.

Do I need to book in advance?

Yes — sauna sessions at Club Contour Studios' Wellness Lounge in Tarzana are by appointment. Booking in advance ensures your preferred time is available and that the space is ready for you when you arrive.
