The Ultimate Sauna Prep Checklist: Everything You Need to Know Before You Go

Whether you’re stepping into a sauna for the very first time or you’re a seasoned regular looking to level up your routine, how you prepare before your session matters just as much as what happens inside. A little know-how goes a long way toward making your experience safe, comfortable, and deeply rewarding.

This guide covers everything you need to check off before you walk through that sauna door — broken down by the three most popular types: Finnish dry saunas, infrared saunas, and steam rooms.

Why Preparation Makes All the Difference

It’s easy to assume you can just walk into a sauna and wing it. And honestly? You probably can — once or twice. But without the right preparation, you’re more likely to feel dizzy, uncomfortable, or cut your session short before the real benefits kick in.

The good news is that getting ready for a sauna session doesn’t require a complicated routine. A few simple habits — some hydration, a quick rinse, and knowing what to bring — can transform a good sauna visit into a great one.

And if you’re not yet fully sold on why you should be visiting a sauna regularly, our article on The Health Benefits of Regular Sauna Use: What Science Really Says makes a pretty compelling case.

Know Your Sauna: Finnish, Infrared, or Steam?

Before we get into the checklist, it helps to understand what you’re walking into. Each sauna type creates a different environment, and your preparation can vary slightly depending on which one you’re using.

🔥 Finnish Dry Sauna

The classic. Finnish saunas use a wood-burning or electric stove to heat rocks, which radiate dry heat throughout the room. Temperatures typically range from 70–100°C (158–212°F) with low humidity (around 10–20%). You may have the option to ladle water over the rocks — called löyly — to create a burst of steam. This is the most traditional sauna experience, and the one most commonly found in public facilities.

🌡️ Infrared Sauna

Infrared saunas use light waves to heat your body directly rather than warming the air around you. As a result, they operate at much lower temperatures — typically 45–60°C (113–140°F) — while still producing a deep, penetrating warmth. Many people find them easier to tolerate, especially beginners. They’re also popular for muscle recovery and relaxation.

💨 Steam Room

Steam rooms are heated by a steam generator and maintain nearly 100% humidity at lower temperatures, usually 40–50°C (104–122°F). The moist heat feels intense despite the lower numbers and is particularly loved for respiratory benefits and skin hydration. If you have sensitive sinuses or a tendency to overheat quickly, take it slow.

Your Complete Pre-Sauna Checklist

✅ 1. Hydrate — Starting Well Before You Arrive

This one isn’t just important — it’s essential. You’re going to sweat a lot, and that process begins the moment you sit down. Walking in already dehydrated is one of the most common mistakes first-timers make.

How to do it right:

• Drink at least 1–2 glasses of water in the hour or two before your session
• Avoid alcohol beforehand — it accelerates dehydration and can cause dizziness in the heat
• Bring a water bottle to sip between rounds if your facility allows it
  Avoid caffeinated drinks immediately before your session, as caffeine is a mild diuretic
• Infrared sauna tip: Because sessions are longer in infrared saunas (often 30–45 minutes), hydration is especially important. Start drinking water earlier in the day.
• Steam room tip: You may sweat less visibly in a steam room (sweat evaporates slower in humid air), but you’re still losing moisture. Don’t skip the water.

✅ 2. Eat Lightly (Or Time Your Meals Right)

A heavy meal and intense heat are not a happy combination. When your body is trying to digest a big lunch and simultaneously manage heat stress, you’re more likely to feel nauseous or sluggish.

Guidelines to follow:

• Aim to eat your last full meal at least 1–2 hours before your session
• A light snack (a banana, a handful of nuts) is fine if you’re feeling peckish
  Avoid greasy, heavy, or spicy foods in the hours leading up to your visit
• Never sauna on a completely empty stomach either — low blood sugar can contribute to dizziness

✅ 3. Shower Before You Go In

Most public sauna facilities require a pre-shower, and for good reason. A quick rinse removes lotions, perfumes, sunscreen, sweat, and oils from your skin, which improves hygiene for everyone sharing the space — and actually makes your own sweat more effective.

What to do:

• Take a brief shower with mild soap before entering
• Use warm (not hot) water — this starts to gently open your pores and prepares your body for the heat
• Pat yourself mostly dry; entering slightly damp is perfectly fine and actually common in Finnish tradition
• Note for steam room visitors: The pre-shower is especially important here given the high humidity, which makes the air more shared between bathers.

✅ 4. Pack the Right Gear

What you bring (and wear) can make or break your comfort. Here’s a quick packing list:

The essentials:

🛁 1–2 towels — one to sit or lie on (required at most facilities), one for drying off
👙 Swimwear or a towel wrap — required at most public saunas; check your facility’s dress code
💧 Water bottle — stay hydrated between rounds
🪣 Sauna bucket & wooden ladle — the classic duo for any Finnish sauna experience. Fill the bucket with water (add a few drops of essential oil if you like) and use the ladle to pour water over the hot rocks, creating a burst of steam called löyly. Most public saunas provide these, but serious regulars often bring their own.
🩴 Flip-flops — for walking around locker rooms and pool areas hygienically
🧴 Gentle body wash and shampoo — for your post-sauna shower

Optional but nice to have:

🪥 Natural bristle body brush — great for dry brushing before your session to exfoliate skin and get circulation going. Look for one with a long removable handle (easier to reach your back) and a rubber strap or grip (essential when your hands are sweaty). A small but worthwhile addition to your sauna bag.
🌿 Essential oils — a few drops of eucalyptus, pine, or birch oil added to the water before ladling over the rocks creates an Aufguss — a fragrant steam ritual beloved in German sauna culture. Even a small bottle goes a long way. Check with your facility first, as some have their own scents or rules about personal oils.
🏳️ Small sweat towel — a lightweight hand towel for wiping sweat during your session. In an Aufguss ritual it doubles as a tool for swinging over your head to circulate the hot steam around the room — a fun and surprisingly effective technique once you get the hang of it.
Alternatively, a sweat scarf is a fun and counter-intuitive fashion item for the sauna.
🪑 Sauna cushion — a small felt or wood-bead cushion that makes the wooden benches much more comfortable, especially during longer sessions. Many regulars swear by them.
🧖 Hair tie — long hair can feel suffocating in a hot room
🎩 Sauna hat — a felt or wool hat that protects your head and ears from the intense heat, letting you stay in longer and sit on the higher (hotter) benches more comfortably. Popular in Finnish and Russian sauna culture and a genuine game-changer for heat tolerance.

📱 Nothing with a screen — seriously, leave your phone in the locker; screens and extreme heat don’t mix, and the whole point is to disconnect

Finnish sauna tip: Some traditional facilities provide a sauna whisk (birch branches, called a vihta) for gentle skin stimulation. If yours does, try it — it’s a centuries-old tradition.

Did you know? In Germany, there is a national day of the sauna on September 24th?

✅ 5. Dress (or Undress) for the Occasion

What you wear in a sauna matters more than most people think.

• At public Finnish saunas, swimwear or a towel is standard in North American facilities
• At private or Nordic-style saunas, bathing in the nude is traditional and perfectly normal
• Avoid tight-fitting synthetic fabrics — they trap heat in uncomfortable ways and can irritate skin
• Remove all jewelry and metal accessories before entering — metal conducts heat and can burn skin quickly
• If you wear contact lenses, consider removing them or bringing glasses; the dry heat of a Finnish sauna or the steam in a steam room can be uncomfortable for lens wearers

✅ 6. Check Your Health and Medications

Saunas are wonderfully safe for most healthy adults, but there are a few situations where you’ll want to exercise caution or check with a healthcare provider first.

Talk to your doctor before using a sauna if you:

• Have a cardiovascular condition, uncontrolled hypertension, or have recently had a heart attack
• Are pregnant (the first trimester especially calls for caution)
• Have a neurological condition, epilepsy, or diabetes with poor circulation
• Have recently had surgery or have open wounds
• Are taking medications that affect sweating, blood pressure, or heart rate (antihistamines, diuretics, beta blockers, etc.)

Skip the sauna that day if:

• You’re feeling unwell, feverish, or coming down with something
• You’ve consumed alcohol
• You’re exhausted to the point of lightheadedness
• Most healthy adults — including older adults and those with well-managed conditions — can enjoy saunas safely with common sense precautions.

✅ 7. Set Realistic Expectations for Your Session Length

One of the best things you can do before going in is to have a rough plan for your session — especially if you’re a beginner.

General guidelines by sauna type:

 

Sauna Type	Beginner Session	Regular User Session
Finnish Dry Sauna	5–10 min per round	10–20 min per round
Infrared Sauna	15–20 min total	30–45 min total
Steam Room	5–10 min per round	10–15 min per round

Important rules of thumb:

• Listen to your body above all else — step out if you feel dizzy, nauseated, or unusually short of breath
• Take cool-down breaks between rounds in Finnish and steam saunas; this is not optional, it’s part of the tradition
• The number of rounds matters less than how you feel — two relaxed rounds beats five rushed ones
• Cooler air or a cool shower between rounds is what resets your body and makes multiple rounds possible

✅ 8. Learn the Unwritten Rules (Sauna Etiquette 101)

You don’t need to be an expert, but a little awareness of sauna etiquette goes a long way toward feeling comfortable and being a respectful guest.

Universal rules:

• Shower before entering — this is both courtesy and usually facility policy
• Sit on your towel — never sit directly on the bench; towels are a hygiene requirement
• Keep noise to a minimum — saunas are spaces of quiet and reflection; save the loud conversations for outside
• Respect personal space — don’t crowd others, especially in a small room
• Don’t wear shoes inside the sauna room itself

For Finnish saunas specifically:

• Ask before pouring water on the rocks if others are in the room — the heat surge (löyly) affects everyone
• Take it up a notch by standing up and swinging your towel over your head. This pushes the heat down for added sauna fun.
• In Nordic traditions, phones and outside conversation are considered disruptive

For steam rooms:

• Be mindful that steam can feel more intense to others; don’t block vents or spray water
• Aromatherapy may be offered at some facilities — be considerate of scent sensitivities
