Gym Sauna Etiquette: Mastering Every Aspect of Gym Saunas

That steamy glass door in your gym’s locker room? Yeah, the one you keep walking past? It’s not as mysterious as it looks.

Whether you’re nervous about your first gym sauna session, unsure about the proper gym sauna etiquette, or you’re ready to take your sauna sessions to the next level, here’s everything you wish someone had told you about using the gym sauna.

From basic etiquette to recovery strategies, and from quick sessions to advanced techniques, we’ll walk you through exactly what to expect and how to make the most of your gym’s sauna. No more wondering if you’re doing it right – by the end of this guide, you’ll feel right at home in the gym sauna.

Always consult your healthcare provider before using a sauna, especially if you have medical conditions or take medications. If you feel unwell during sauna use, exit immediately and seek appropriate medical attention if needed.

What Should You Know Before Using a Gym Sauna?

Maybe you’ve spotted people walking in and out of your gym’s sauna, looking relaxed and refreshed. But if you’re standing there, towel in hand, wondering what actually goes on behind that glass door – you’re not alone. From wearing the right things to knowing how long to stay inside, there’s a whole mini-culture around sauna use that nobody really talks about.

The good news? Once you know the basics, you’ll feel right at home in there. Let’s start with the three questions everyone secretly wonders about but rarely asks.

1. What Types of Saunas Will You Find at the Gym?

Traditional Dry Sauna: Most common in gyms. Wooden interior, electric heater, temperatures between 150-185°F. Your sweat evaporates quickly, making the heat feel more manageable.

Steam Room vs Sauna: Often confused but totally different. Steam rooms run cooler (110-115°F) but feel intense due to 100% humidity. Your sweat doesn’t evaporate, creating that dense, wet heat feeling.

Infrared Saunas: Newer, boutique gyms often have these. They heat your body directly rather than the air. Lower temperatures (120-140°F) but you still sweat plenty. Some people find these more comfortable for longer sessions.

2. What Should You Wear in a Gym Sauna?

Getting dressed for the gym sauna doesn’t need to be complicated. Most gym-goers keep it simple with a clean towel wrapped around them – it’s the most practical choice. If you’re using a sauna near the pool area or main gym floor, a swimsuit works perfectly too.

The key rule? Always bring two towels. One to wear or wrap yourself in, another to sit on. Nobody wants to share bench contact with strangers, and gyms usually enforce this rule strictly.

Mike’s first-time story about walking in wearing running shoes gets shared often in our local gym. “The looks I got,” he says, “taught me more about sauna etiquette than any sign ever could.” Keep it simple – leave your shoes, socks, and workout gear in your locker.

3. How Long Should You Stay in a Gym Sauna?

Your first sauna visit should be brief – think 5 to 8 minutes max. It’s like getting into a hot bath; you need time to adjust to the heat. Watch the clock (there’s usually one mounted outside the glass door) and listen to your body. Feeling lightheaded? That’s your cue to leave.

As you get used to the heat, you can stretch your sessions to 10 or 15 minutes. Some experienced sauna users stay up to 20 minutes, but never feel pressured to push yourself that far.

Sarah, a regular at my gym, learned this the hard way: “I tried to tough it out for 20 minutes because that’s what my friend does. Big mistake. Now I know 10 minutes works perfectly for me.“

How to Use a Sauna at the Gym

What to Bring

First-time sauna users often wonder what to bring and how long to stay. Keep it simple: pack two clean towels (one to sit on, one to dry off), a water bottle, flip flops, and fresh clothes. Some regulars also bring a small face towel and a hair tie for comfort.

Getting Ready

Getting started takes just a few simple steps. Drink plenty of water before you go in – about 16-20 ounces works well. Take a quick shower, leave your jewelry and phone in your locker, and grab your towels. Most people find the best time for sauna is 10-15 minutes after their workout, when their muscles are already warm.

Your First Session

Your first time in the sauna shouldn’t last long. Five to eight minutes gives your body time to adjust to the heat without overdoing it. Pick a spot on the lower bench where the temperature feels manageable – usually around 150-185°F in traditional saunas. Focus on breathing normally and staying relaxed. If you start feeling uncomfortable, that’s your cue to head out.

How to Cool Down Properly After Your Sauna

The 15-Minute Rule: Your body needs about 15 minutes to return to normal temperature after a sauna session. Don’t rush this process – quick temperature changes can make you dizzy or disorient you.

Gradual Cooling Process:

1. Exit slowly and sit in the transition area (5-7 minutes), letting your breathing and heart rate normalize
2. Take a lukewarm shower, gradually adjusting to cooler temperatures as your body adjusts
3. Hydrate properly with water and electrolytes – sip slowly rather than gulping
4. Rest in a moderate temperature area until you feel your body temperature stabilize
5. Wait to dress until you’ve stopped sweating completely to avoid damp clothes

Common Mistakes to Avoid

Even regular sauna users sometimes make rookie mistakes. Many newcomers try staying too long their first few times or skip drinking water before and after. Some rush through the cool-down process or try working out right after their session. Others bring their phones inside (bad for the phone, worse for the peaceful atmosphere) or wear too many clothes.

How to Build a Regular Sauna Routine

Regular sauna users develop their own rhythm over time. Morning people often start with a light workout, followed by 10-15 minutes of sauna time – just enough to feel refreshed without getting sluggish. Evening users might stretch out their sessions longer, using the quiet time to decompress after a long day.

Notice how your body responds to different patterns. Some people feel energized after a sauna session, while others feel ready for rest. Neither reaction is wrong – it’s about finding what works for you. Many regular users find their sweet spot around three sessions per week, though some go daily.

Seasonal changes matter too. Winter brings more people seeking warmth, making busy times busier. Summer usually means shorter, less crowded sessions. Your tolerance might change with the seasons, and that’s natural.

How to Practice Proper Gym Sauna Etiquette

Entering the Space

Steam rises in lazy curls as another person enters the sauna. There’s an art to joining others in this small, heated space. The door opens and closes quickly, keeping precious heat inside. Think of the sauna as a quiet sanctuary – a phone-free zone where you can disconnect. Regulars find their spot without fuss, settling in quietly. A slight shift from others makes room – it’s these small courtesies that make the space work.

The Art of Sauna Conversation

Conversation follows natural rhythms here. Sometimes silence fills the room like another form of warmth – other times, quiet chat flows among regulars. Reading the room becomes second nature. If others are meditating or have their eyes closed, keeping quiet shows respect for their space.

Choosing Your Spot

The top bench isn’t just about claiming the best spot – it’s about heat tolerance. New folks often learn by watching: notice where others sit, how they adjust their towels, when they choose to leave. Always sit on a fresh towel – it’s both courtesy and cleanliness. Never exercise or do stretches in the sauna – it’s a space for sitting quietly, not working out.

Managing Temperature

That unspoken rule about temperature changes? It’s sacred here. A quick “mind if I add some heat?” shows you understand it’s a shared space. The same goes for pouring water on the hot rocks – always ask first. Those sudden steam bursts can overwhelm others if they’re not ready.

Sharing the Space

Keep your movements small and controlled. Spread out when it’s empty, and bunch up a bit when it’s busy. Your towel isn’t just for sitting – it’s part of the social contract.

Maria, a morning regular, still laughs about the guy who brought his entire skincare routine into the sauna. “Face mask, hair treatment, the works. The staff had to explain why that wasn’t okay.” The sauna creates its own social patterns, subtle but clear once you know what to look for.

Important Gym Sauna Rules and Policies

Chain-Specific Sauna Policies

While most sauna etiquette remains consistent across gyms, individual fitness chains often have their own specific policies. Here’s what you’ll typically encounter at major gym chains:

• Planet Fitness: No outside items, strict time limits, must wear appropriate swimwear
• LA Fitness: Pre-sauna shower required, no personal oils or products, towel mandatory
• Crunch: Towel required for sitting, no workout clothes allowed inside
• 24 Hour Fitness: Age restrictions (18+), specific cleaning protocols, no personal heating elements

Universal Sauna Rules at Gyms

• Follow posted maximum occupancy limits
• Respect time limits (usually 15-20 minutes per session)
• Always shower before entering
• Wear proper attire (towel or swimsuit)
• No personal care products, oils, or aromatherapy
• Keep emergency exits clear and accessible
• Report any maintenance issues immediately
• No electronics (phones/headphones) or reading materials
• Never bring glass or breakable items inside
• Follow posted age restrictions

Most gyms post their specific rules near the sauna entrance. When in doubt, check with staff – they’d rather answer questions than deal with problems later. Remember that breaking these rules consistently could result in losing sauna privileges or even gym membership.

What Medical Conditions Affect Sauna Use?

Several medical conditions require careful consideration before using the sauna:

• Diabetes: Heat affects blood sugar levels and insulin absorption rates, requiring close monitoring
• Multiple sclerosis: Temperature sensitivity can trigger symptom flares and should be discussed with your healthcare provider
• Respiratory issues: Hot air may impact breathing capacity and require shorter sessions
• Heart conditions: Heat stresses the cardiovascular system, making medical clearance essential
• Circulation problems: Blood vessel dilation requires extra caution and potentially modified session lengths

What Should You Do if You Feel Unwell in a Sauna?

Your body has clear warning signals, and knowing how to respond is crucial. That first wave of dizziness can catch anyone off guard – the room spins slightly, your heart picks up speed, and suddenly the heat feels overwhelming. Here’s what to do:

1. Don’t try to push through it.
2. Move to a lower bench immediately, or better yet, head for the door.
3. Take slow, steady breaths.
4. Sip water once you’re outside.
5. Give yourself time to cool down before deciding whether to return.

Most sauna troubles come from doing too much too soon. Your first few sessions might last just minutes, and that’s exactly right. You’ll build tolerance naturally over time, but rushing the process helps nobody.

Jim Adams, a CrossFit trainer at Elite Fitness in Boston, learned this lesson the hard way: “I thought I could handle the heat like I handle heavy weights. Pushed too hard my first time and nearly passed out. Now I know better – start slow, build up gradually.“

Safety and Troubleshooting in the Gym Sauna

When things go wrong in the sauna, knowing what to do makes all the difference. Even experienced users sometimes face unexpected situations – from feeling unwell to noticing equipment problems.

Emergency Situations

If someone looks distressed in the sauna, act quickly but calmly. Help them move to the lower bench or out of the sauna entirely. Alert gym staff immediately – they’re trained for these situations and know exactly what to do. Stay with the person until help arrives if you can do so safely.

Equipment Issues

Saunas need regular maintenance to work safely. Notice rough or splintered benches? Tell the staff right away. The same goes for doors that don’t seal properly or unexpected temperature swings. That odd smell or strange sound from the heater? Don’t ignore it – report it. Good maintenance keeps everyone safe.

When to Skip the Sauna

Some days, the sauna just isn’t worth the risk. Skip your session if you’re feeling under the weather, severely dehydrated, or unusually tired. The same goes for right after a big meal or if you’ve had a few drinks. The heat will still be there tomorrow.

If medications or health conditions make you sensitive to heat, check with your doctor first. Better to be cautious than to learn the hard way that sauna heat doesn’t mix well with your current situation.

Remember: A good sauna session should make you feel better, not worse. When in doubt, step out. The sauna’s been around for centuries – it’ll still be there when you’re ready to return.

How to Adapt to Sauna Heat Safely

Your body adapts to sauna heat gradually, like getting used to summer weather. Those first few sessions might feel intense – that’s normal. The dry heat wraps around you differently than humidity or hot weather. Your breathing might quicken at first, then settle into a natural rhythm.

Starting on the lower bench makes sense. The temperature difference between the bottom and top bench can surprise you – sometimes up to 20 degrees. Give yourself time to find your comfort zone. Some people never move to the top bench, and that’s perfectly fine.

Pay attention to how you feel outside the sauna too. Most people need about 10 minutes to cool down properly afterward. Rushing back to normal activities can leave you feeling lightheaded. Take your time. Let your body temperature settle naturally.

Best Times to Use a Gym Sauna: Complete Schedule Guide

When Is the Best Time to Use a Gym Sauna?

Timing your sauna session right can make all the difference. Those early birds hitting the sauna before their workout? They keep it brief – just enough to warm up tight muscles on cold mornings. Five minutes max does the trick, though most regulars skip the pre-workout sauna entirely.

The sweet spot comes after your workout, once your breathing returns to normal. Take a quick rinse first – you’ll feel better, and your fellow sauna users will appreciate it. Tom, a marathon trainer, learned this through trial and error: “I used to jump straight from my run into the sauna. Now I cool down first – makes a huge difference in how good I feel after.“

Don’t feel like working out? The sauna works perfectly fine as a standalone activity. Many regulars pop in just for a sauna session, especially during quieter mid-morning or early afternoon hours. Just avoid going in right after a meal.

How to Handle Peak Hours at the Gym Sauna

Every sauna has its daily rhythm. Early mornings bring the pre-work crowd, mostly regulars who know each other’s routines. They keep their sessions short and sweet, making room for others during the 6-8 AM rush.

The lunch crowd moves differently. You’ll find a mix of people watching the clock and others taking their time. Usually, there’s enough space to stretch out a bit, making it perfect for longer sessions if you’re not rushing back to work.

After work tells another story entirely. The 5-7 PM crowd tends to fill every bench, so reading the room becomes crucial. Watch how others time their sessions and follow their lead. Lisa, a sauna veteran, shares her secret: “Friday evenings are dead quiet. Same with Sunday afternoons – perfect if you want the sauna to yourself.“

What Special Situations Should You Watch Out For in a Gym Sauna?

Wearing contact lenses? They can get uncomfortable in the heat. Some people remove them before entering, others limit their time. If your contacts start bothering you, it’s better to cut your session short than risk eye irritation.

Dealing with long hair brings its own challenges. The heat can make hair products melt and run – not fun for anyone sitting below you. A clean shower cap works well if you’re trying to protect a hairstyle. Otherwise, a loose bun keeps hair off your neck without causing problems.

Gym schedules sometime mean choosing between a workout and sauna time. No perfect answer exists – pick what matters most that day. Some regulars alternate, using the sauna on lighter workout days or rest days.

How Does a Gym Sauna Help with Recovery?

Post-workout sauna sessions can do more than just feel good. Many athletes and regular gym-goers use sauna time strategically for better recovery.

The science behind sauna recovery is pretty clear. Heat exposure increases blood flow to your muscles, which can help speed up the repair process (Luleå University of Technology, 2024). Think of it like a gentle, full-body warm-down that keeps working even while you sit still.

Basketball players and athletes have shown faster recovery from intense training when using the sauna, with research demonstrating accelerated recovery through improved thermoregulation (Laukkanen et al., 2015). Runners found their legs felt fresher for their next workout. Even if you’re not training for competition, you might notice less muscle stiffness the day after a tough workout.

Other Benefits of Using a Gym Sauna

Let’s clear up some sauna myths. Despite what you might have heard, saunas won’t melt away fat or mysteriously detox your body. The real benefits are more straightforward – and backed by science.

Cardiovascular Health: Regular sauna use gets your heart pumping in ways similar to moderate exercise, with studies showing heart rate increases comparable to light-moderate exercise during sauna sessions (Laukkanen et al., 2015). The heat causes your blood vessels to expand, improving circulation and potentially helping with blood pressure over time.

Mental Benefits: There’s something uniquely calming about sitting in a quiet, warm space after a long day. Research has shown that regular sauna use is associated with a 37% reduced risk of mental health disorders (Kunutsor et al., 2018). Many sauna users report better sleep on days they use the sauna, and the forced disconnection from phones and devices creates a natural stress-relief period.

The Weight Loss Truth: Alex, who hits the gym daily, shares a common misconception: “My trainer told me sitting in the sauna burns tons of calories.” The truth? You’ll lose water weight through sweat, but it comes right back when you drink water. Your heart rate increases from the heat, which might fool your fitness tracker into showing a high-calorie burn – but don’t be fooled.

Advanced Sauna Strategies

Once you’ve mastered the basics, there’s more to explore with advanced sauna practices that can enhance your benefits.

Building Heat Tolerance

Most regulars build their tolerance over about a month. Start with short sessions on the lower bench, then gradually increase both duration and heat exposure until you’re comfortable with 20-minute sessions on the upper bench.

Contrast Therapy

More experienced users often practice contrast therapy – alternating between sauna heat and cool showers. A typical pattern involves 10-15 minutes in the sauna, followed by a cool shower, then a brief rest before another round. This technique can boost circulation and reduce muscle soreness more effectively than heat alone.

Timing for Your Goals

Different sauna patterns serve different purposes. Recovery-focused sessions work best as two shorter rounds with a break between them. For relaxation, one longer 20-minute session often proves more effective. Listen to your body and adjust your timing based on how you feel that day.

The key to advanced sauna use isn’t just spending more time in the heat – it’s about being strategic with your sessions to match your goals.

Final Thoughts

The gym sauna offers more than just heat – it provides a unique space for recovery, relaxation, and routine. Your first visits might feel uncertain, but that changes quickly. Start slow, watch and learn, and find your comfort zone.

Remember that everyone in there started as a beginner. Those quiet regulars on the top bench? They once stood at the door, towel in hand, wondering what to do next. Now they’re part of the natural flow, and soon you will be too.
