How long should an infrared sauna session be?

If you are new to sauna, start with 20 to 30 minutes. Most regular users settle into a 30 to 45 minute session, which is enough time to work up a meaningful sweat without overdoing it.

What may infrared sauna therapy support?

Research suggests that regular infrared sauna use may support recovery from exercise, cardiovascular conditioning, sleep quality, stress regulation, circulation, and skin health. It is not intended to diagnose, treat, cure, or prevent any disease.

About Infrared Sauna

What Is an Infrared Sauna?

Infrared saunas use infrared light to warm your body directly instead of heating the air around you. The result is a deeper sweat at a more tolerable temperature, which makes it easier to stay in long enough to actually get the benefit. Our sauna at Defiant also includes an additional traditional heater — so if you prefer the higher heat of a classic Finnish-style session, the cabin can climb up to around 200°F.

As your core temperature rises, your body responds the way it would to moderate exercise: your heart rate increases, blood vessels dilate, and you start to sweat. Research suggests this thermoregulatory response may support recovery, cardiovascular conditioning, sleep quality, and stress regulation.

Our sauna seats up to three people comfortably, so you can use it solo or bring a friend. Most sessions run 30–45 minutes.

The Science

How Infrared Sauna Works

Direct, Penetrating Heat

Infrared light warms your body directly, so the heat reaches deeper into your tissue. Our hybrid cabin can run as an infrared-only session or crank up to around 200°F with a traditional heater for a classic Finnish-style sweat.

Cardiovascular Response

As your core temperature rises, your heart rate climbs and blood vessels dilate — a response similar to moderate-intensity exercise. Research suggests regular sauna use may support cardiovascular conditioning over time.

Sweat & Circulation

A deep sweat does more than cool you down. Increased circulation may help deliver nutrients to tissues, support skin health, and aid the body’s natural detoxification pathways through sweat.

Recovery & Downshift

After the heat, the body shifts into a parasympathetic, restorative state. Many people use sauna in the evening to wind down, support sleep quality, and recover from training.

Potential Benefits

Benefits of Infrared Saunas

Heat therapy is one of the most studied wellness modalities in the world, and regular sauna use is associated with a wide range of potential benefits. People come in for different reasons, but these are the most common:

+ Recovery from training, soreness, and stiffness
+ Cardiovascular conditioning and circulation
+ Stress regulation and parasympathetic recovery
+ Sleep quality and evening wind-down
+ Skin health and a deep, productive sweat
+ Detoxification support through sweat
+ A simple, low-effort longevity habit

Want the full contrast therapy effect? Pair an infrared sauna session with cryotherapy to amplify the recovery response. Hot then cold — that’s where things get interesting.

What to Expect

Your Session, Step by Step

Hydrate & Arrive

Drink plenty of water before you come in. Wear minimal clothing or a swimsuit, and bring a towel. We provide everything else.

Settle In

The cabin is preheated and ready. Bring a book, headphones, or just close your eyes. The heat builds gradually so you have time to ease in.

Sweat It Out

Sessions typically run 30–45 minutes. You’ll work up a deep, full-body sweat. Step out and rehydrate any time you need to.

Cool Down & Recover

Rinse off, hydrate again, and let your body shift back to baseline. Many clients pair the session with cryotherapy for the full contrast therapy effect.

FAQ

Common Questions

Everything you need to know about infrared sauna at Defiant in Lisle, IL.

A traditional Finnish sauna heats the air around you, often to 180–200°F. A standard infrared sauna uses infrared light to warm your body directly while the air stays cooler. Our sauna at Defiant is a hybrid: it delivers infrared heat and includes an additional traditional heater, so the cabin can run cooler for a more tolerable infrared session or get up to around 200°F for a classic Finnish-style experience.

Most of the research linking sauna use to long-term health benefits looks at 2–4 sessions per week. That said, even one session a week can support recovery and stress regulation. We’ll help you find a cadence that fits your goals and schedule.

If you are new to sauna, start with 20–30 minutes. Most regular users settle into a 30–45 minute session, which is enough time to work up a meaningful sweat without overdoing it. Listen to your body and step out any time you need to.

Yes — alternating heat and cold is one of the most popular ways to use the sauna. The contrast triggers a strong circulatory and nervous system response that many people find energizing. Ask our team about pairing a sauna session with cryotherapy.

Wear minimal clothing, gym wear, or a swimsuit — whatever you are comfortable with. Bring a towel to sit on and another to dry off. We recommend hydrating well before your session and bringing water with you.
