Infrared sauna studios are booming, but walking in unprepared can leave you confused about what to wear, how long to stay, or whether the heat is actually working. This guide covers exactly what happens during your first session, so you can focus on relaxation instead of second-guessing yourself.
Arrival and Check-In
Plan to arrive 10–15 minutes early. Most infrared sauna studios require you to fill out a health questionnaire covering any cardiovascular conditions, medications, or recent injuries. This is standard and helps staff recommend the right temperature and duration for your body.
Expect to pay between $40–$80 for a single 30- or 45-minute session at a dedicated infrared sauna studio, though many offer introductory rates of $25–$35 for first-timers. Ask about package deals upfront—studios often bundle 5, 10, or unlimited monthly sessions at discounts of 20–40% off single rates.
What to Bring and Wear
Wear minimal clothing or a lightweight robe. Most studios provide disposable or washable robes; some let you wear shorts and a t-shirt. Avoid cotton if possible—it absorbs sweat and stays damp. Pack a towel to sit on (studios provide these) and bring water in a container you can leave outside the sauna (metal or glass, never plastic).
Leave your phone and electronics outside. Infrared saunas operate around 120–150°F (49–65°C) internally, and humidity levels vary depending on the sauna type, so devices can malfunction.
Inside the Sauna Room
Your technician will show you to a private or semi-private booth. Infrared saunas use infrared light panels that warm your body directly rather than heating the air like traditional saunas. You'll feel a gentle, penetrating warmth start within 2–3 minutes. It should feel pleasant, not painful or claustrophobic.
Most first sessions last 30 minutes. Don't push to a full 45 minutes on day one—your body needs time to acclimate. Start at the recommended temperature (usually 120–130°F for beginners) and let staff know if you want adjustments.
What Your Body Will Do
You'll begin sweating within 5–10 minutes. This is normal and healthy. Infrared saunas typically produce more sweat than traditional ones because the heat penetrates deeper into tissue rather than just heating skin surface. Bring water inside with you and sip regularly—dehydration is real, and you won't realize how much fluid you're losing.
Some people feel lightheaded if they stand up too quickly after a session. Take your time exiting and cool down gradually. Sit in the reception area for 5 minutes before leaving.
After Your Session
Shower within 30 minutes to rinse off sweat and salts. Drink electrolyte water or coconut water, not just plain water, to rebalance minerals. Your skin may feel flushed for 15–30 minutes—this fades quickly.
Most people feel relaxed and slightly fatigued after their first session. This is normal; your body has been working hard. Avoid strenuous exercise for at least 2 hours post-session.
What to Look for in a Studio
Quality matters. Check that the studio uses medical-grade infrared heaters (not cheap heating elements) and maintains consistent temperature control. Ask about sauna type—far-infrared saunas are most common and best for beginners, while full-spectrum or near-infrared options exist at premium studios.
- Cleanliness: Surfaces should be sanitized between sessions; ask about their protocol.
- Privacy: Single-occupancy booths beat shared rooms for first-timers.
- Staff knowledge: They should explain how to use the sauna and answer health questions without overblown wellness claims.
- Trial sessions: Reputable studios offer introductory rates specifically so you can test whether infrared saunas work for your body.

Frequently Asked Questions
Q: Will I overheat or get dehydrated on my first try? Mild dehydration risk exists if you don't drink water during the session, but overheating is unlikely since infrared saunas operate at lower temperatures than traditional ones. Stay hydrated and alert to how your body feels.
Q: Can I bring my phone to take photos inside the sauna? Not recommended—the combination of heat and moisture can damage most phones, and many studios have strict no-device policies for this reason.
Q: How often should I go after my first session? Beginners typically see benefits with 2–3 sessions per week. Listen to your body; daily sessions aren't necessary and may cause excessive dehydration.
