Before You Go In
Hydrate
Drink a full glass of water 15-30 minutes before your session. You're going to sweat - a lot. Starting dehydrated is the fastest way to feel terrible. Avoid alcohol before saunaing. Beer and sauna are a Finnish tradition, but that's for experienced users who know their limits, not first-timers.
Shower First
Take a quick rinse before entering. This washes off lotions, deodorant, and sweat that would otherwise bake into the hot air. Everyone in the sauna will appreciate it, and it's considered basic etiquette everywhere.
What to Wear
This depends entirely on the setting:
- Gym sauna - Swimsuit, shorts, or a towel wrap. Check the posted rules.
- Spa or bathhouse - Varies wildly. Some are nude-only, some require swimwear. Ask at the front desk.
- Home sauna - Whatever you're comfortable with. Most people go nude at home since it's the most comfortable option.
- Always bring a towel to sit on, regardless of what you're wearing.

Your First Session: What to Expect
The First Few Minutes
When you walk in, the heat hits you immediately. Your skin will feel hot, and you might think there's no way you can handle this. Give it 2-3 minutes. Your body starts to adjust, and what felt unbearable at first becomes manageable.
Where to Sit
Heat rises, so the upper bench is significantly hotter than the lower bench. As a first-timer, start on the lower bench. You can move up after a few sessions once you know how your body responds. Sit on your towel - the wood is hot and direct skin contact on the bench isn't comfortable.
How Long to Stay
Your first session should be 10-15 minutes. That's it. Don't try to match the person who's been sitting there for 30 minutes - they've been doing this for years. If you feel dizzy, lightheaded, or nauseous at any point, leave immediately. There's zero shame in a short session.
Over time, you'll naturally build tolerance and extend your sessions to 15-20 minutes.
What Happens to Your Body
Here's the progression you'll notice:
- Minutes 1-3 - Skin feels hot. Heart rate picks up slightly.
- Minutes 3-5 - Sweating begins. It starts slow and then ramps up.
- Minutes 5-10 - Full sweating mode. Your skin is visibly wet. You might feel your pulse in your temples.
- Minutes 10-15 - Deep relaxation kicks in for many people. Muscles feel loose. Mind quiets down.
- Beyond 15 minutes - For experienced users. First-timers should exit around this mark.
After Your Session
Cool Down Properly
Don't just walk out and get dressed. Your body needs to cool down gradually. Options include:
- A lukewarm or cool shower (cold if you're feeling adventurous)
- Sitting outside in the fresh air for 5-10 minutes
- A dip in a cold plunge pool if one's available
The contrast between hot and cool is where a lot of the health benefits come from. It's also incredibly refreshing.
Rehydrate
Drink at least 16 ounces of water after your session. You just lost a significant amount of fluid through sweat. Water is best. Coconut water or an electrolyte drink works if you were in for a longer session. Skip the soda.
Rest
Sit down for 10-15 minutes after your session before jumping back into your day. Your body just went through something similar to a moderate workout. The relaxation you feel is real - enjoy it.
Common First-Timer Mistakes
- Staying too long - The biggest mistake. You're not proving anything by sitting there until you feel sick. 10-15 minutes is plenty.
- Not drinking enough water - Dehydration causes headaches, dizziness, and fatigue. It's the reason most people have a bad first experience.
- Going right after a heavy meal - Your body is directing blood to your digestive system. Sauna redirects it to your skin. The result is discomfort. Wait at least an hour after eating.
- Bringing your phone - The heat and humidity will damage it. Also, this is your 15 minutes to unplug. Leave it in the locker.
- Expecting to feel great immediately - Some people love the sauna from day one. Others need 3-4 sessions before it clicks. Give it a fair chance.
What to Bring
Here's your first-timer checklist:
- One large towel to sit on
- One small towel to wipe sweat
- Water bottle (leave it outside the sauna door or bring it in if allowed)
- Flip flops or sandals for walking to and from the sauna
- Swimsuit if the setting requires one
- Change of clothes for after
Types of Saunas You Might Encounter
A quick primer so you're not confused:
- Traditional/Finnish sauna - Heated by a stove with rocks. Hot, dry air at 170-195°F. You can throw water on the stones for bursts of steam.
- Infrared sauna - Heated by infrared panels. Lower air temperature (120-150°F) but the heat penetrates directly into your body. Feels different - gentler but still effective.
- Steam room - Not technically a sauna. Lower temperature (110-120°F) but extremely high humidity. Wet heat versus dry heat.
The Bottom Line
Your first sauna session is simple: hydrate, shower, start on the lower bench, stay 10-15 minutes, cool down, drink water. That's the whole formula. Don't overthink it. Most people walk out of their first real sauna session thinking, "Why didn't I try this sooner?"
