How to Use a Sauna: The Most Important Things to Know

December 22, 2025

Of all the questions we hear, this one comes up most often. And honestly? We love it. It means you're exploring something new, something that seems appealing but feels a little unfamiliar. Maybe you've heard about the incredible benefits of sauna bathing, or perhaps a friend raved about their experience. Whatever brought you here, you're in the right place.

The truth is, there's nothing mysterious or complicated about using a sauna properly. What might feel like an intimidating ritual is actually one of the most natural, intuitive wellness practices humans have enjoyed for thousands of years. At Eden Hut, we share the same guidance with all of our clients, whether they're seasoned sauna enthusiasts or complete beginners. By the end of this article, you'll understand exactly how to approach your first session, what to expect as you gain experience, and how to make sauna bathing a transformative part of your life.

Preparing for Your Sauna Session

The experience actually begins before you step inside. Proper preparation sets you up for a comfortable, beneficial session and helps your body respond beautifully to the heat.

Hydration Is Everything

Start drinking water 30 to 60 minutes before your session. Aim for at least 16 to 20 ounces. Your body will lose significant fluids through sweating, so think of this as filling your tank before a journey. Plain water works perfectly, though coconut water or drinks with electrolytes can be helpful if you're planning a longer session.

After your sauna, continue hydrating. You'll likely lose about a pint of fluid during a typical 15-minute session, sometimes more. Keep a water bottle nearby and sip between rounds if you're doing multiple sessions.

Timing Your Meals

Heavy meals and saunas don't mix well. Your body diverts blood flow to aid digestion, and adding intense heat to that equation can leave you feeling uncomfortable or nauseous. Avoid eating large meals within two to three hours of your sauna session.

If you're hungry, a light snack about an hour beforehand works beautifully. Think fruit, a handful of nuts, or something similarly gentle. An empty stomach can make you feel lightheaded in the heat, so find that comfortable middle ground.

The Pre-Sauna Shower

Always shower before entering the sauna. This simple step removes oils, lotions, perfumes, and the day's accumulation of dirt and sweat from your skin. It's partly about hygiene for yourself and others, but it also prepares your pores to open and function properly.

Take a few minutes under warm water. Dry off completely before entering, as this helps your body start perspiring more quickly once you're in the heat.

What to Remove, What to Bring

Remove all jewelry before your session. Metals heat up rapidly and can become uncomfortably hot or even cause burns. Take off watches, rings, necklaces, and earrings.

Skip the makeup and perfume. These products block your pores and can feel unpleasant when heated. If you typically wear cosmetics, plan your sauna for a time when you can go bare-faced.

Bring two towels. One is for sitting or lying on (you should never sit directly on the wooden benches), and the other is for drying off afterward. Some people also appreciate flip-flops for walking to and from the sauna, though they stay outside during the actual session.

Check With Your Doctor If Needed

If you have cardiovascular disease, high or low blood pressure, diabetes, are pregnant, or take medications that affect your body's temperature regulation or cause drowsiness, consult your healthcare provider before using a sauna. Most people can safely enjoy saunas, but these conditions require professional guidance to ensure your safety.

Beginner's Guide: Your First Sessions

Starting slowly is the smartest approach. Your body needs time to adapt to heat exposure, and there's absolutely no benefit to pushing through discomfort.

Session Length for Beginners

Keep your first session brief, just 5 to 10 minutes. This gives your body a chance to experience the heat without overwhelming your system. The goal isn't endurance. The goal is to introduce your body gently to this new practice.

During your second and third sessions, you might extend to 10 to 12 minutes if you felt comfortable. By your fourth or fifth visit, 12 to 15 minutes often feels natural. Listen to your body throughout. Some people adapt quickly, while others prefer to stay at shorter durations longer.

Choosing Your Spot

Heat rises, which means the upper benches in a sauna are significantly hotter than the lower ones. As a beginner, start on a lower bench where temperatures are gentler. You can always move up as you become more accustomed to the heat.

Place your towel on the bench and sit or lie on it. Many people find lying down more comfortable because it keeps your whole body at a consistent temperature. Sitting means your head is in the hottest zone while your feet are in the coolest.

What to Expect

Your heart rate will increase, similar to moderate exercise. You'll start sweating within a few minutes, though this varies from person to person. Some people perspire heavily right away, while others take longer to build up a sweat. Both responses are completely normal.

Breathe steadily and deeply through your nose. This helps filter and slightly cool the air before it reaches your lungs. Stay relaxed. Let your mind quiet. Many people find the sauna becomes a rare opportunity for meditation or simply peaceful silence.

Frequency for Beginners

Start with once or twice per week. This gives your body time to adapt between sessions. After a few weeks, you can increase to two or three times weekly if you enjoy the experience and feel good afterward.

When to Exit

Leave immediately if you experience dizziness, lightheadedness, nausea, or a headache. These are signals that your body needs to cool down. Don't try to push through discomfort. There's no prize for staying longer than feels right.

Even without those warning signs, exit when you feel sufficiently warm. The Finnish tradition is simple and wise: stay until you feel hot enough, then leave. Your body knows.

Expert-Level Sauna Practice

Once you've built tolerance over weeks or months of regular sessions, you can explore the full depth of the sauna experience.

Extended Sessions and Multiple Rounds

Experienced users typically stay 15 to 20 minutes per round, though some extend to 30 minutes. The key difference from beginners isn't just duration but comfort. If 20 minutes feels easy and pleasant, you've adapted well.

The traditional Finnish approach involves multiple rounds with cooling periods between each. A complete session might look like this:

Round One (10 to 15 minutes): Dry heat to warm your body evenly. Sit quietly, breathe deeply, let the heat penetrate your muscles and joints.

Cool Down (10 to 15 minutes): Step outside, take a cool or cold shower, or if you're feeling adventurous, a plunge in cold water. Let your heart rate normalize. Drink water. Rest.

Round Two (15 to 20 minutes): This time, create löyly (steam) by ladling water onto the heated stones. The steam makes the heat feel more intense and helps warm your core more efficiently. If you have essential oils mixed with your water, this is when those aromas fill the space.

Cool Down (10 to 15 minutes): Repeat the cooling process. Many people find this second cool-down deeply refreshing.

Optional Round Three: If you're feeling energized rather than tired, a shorter third round can be wonderful. Keep this one gentler, around 10 to 15 minutes.

Frequency for Regular Users

Research shows remarkable cardiovascular benefits for those who use saunas four to seven times per week. Finnish studies found that this frequency reduced the risk of sudden cardiac death by 63% and stroke risk by 60% compared to once-weekly use.

For most regular users, three to four sessions per week provides substantial benefits. Athletes recovering from training might use saunas four to five times weekly. If you have the time and enjoy daily sessions, that's generally safe for healthy individuals, though you should monitor for any signs of dehydration or fatigue.

Advanced Techniques

Vihta (birch whisk): Traditional Finnish practice involves gentle self-massage with bundled birch twigs. The light tapping promotes circulation and the birch oils are soothing to the skin. If you try this, movements should be gentle and rhythmic, not vigorous.

Contrast therapy: Alternating between intense heat and cold exposure amplifies many benefits. The hot-cold cycle improves circulation, reduces inflammation, and creates an invigorating sense of alertness followed by deep relaxation.

Dry brushing: Some people dry brush their skin before entering, which helps exfoliate and prepare the skin for sweating. After your session, you can also do gentle exfoliation to remove the layer of dead skin cells that the heat has loosened.

Creating Your Ritual

Expert sauna users often set aside 1.5 to 2 hours for a complete experience. This isn't about staying in the heat that entire time, it's about giving yourself unhurried space for the full cycle of warming, cooling, resting, and perhaps repeating. This transforms sauna bathing from a quick heat exposure into a genuine wellness ritual.

Using Sauna for Specific Health Benefits

While everyone experiences relaxation and stress relief, you can optimize your sessions for particular health goals.

Cardiovascular Health

For heart health and longevity, aim for three to four sessions weekly, 15 to 20 minutes each. The heat raises your heart rate similar to moderate exercise, strengthening your cardiovascular system over time. Studies have shown regular sauna use reduces blood pressure, improves arterial compliance, and decreases the risk of cardiovascular disease.

The cardiovascular benefits are dose-dependent, meaning more frequent use correlates with greater protection. However, if you have any heart condition, work with your doctor to establish a safe routine.

Muscle Recovery and Pain Relief

Athletes and active individuals can use saunas post-workout to enhance recovery. The increased blood flow delivers oxygen and nutrients to fatigued muscles while helping clear metabolic waste. Sessions of 10 to 15 minutes three to four times weekly work well for this purpose.

For chronic pain conditions like arthritis, rheumatoid arthritis, or fibromyalgia, regular sauna use can provide meaningful relief. The heat reduces muscle tension, improves joint flexibility, and may help decrease inflammation. Two to four sessions weekly often prove beneficial.

Stress Reduction and Mental Health

If your primary goal is stress relief, two to three sessions weekly can be perfect. The sauna creates a rare opportunity for complete disconnection. No screens, no demands, just heat and stillness. Many people find this meditative quality as valuable as the physical benefits.

Research has shown that men who used saunas four to seven times weekly had a 77% reduced risk of developing psychotic disorders compared to those using saunas once weekly or less. Regular heat exposure appears to have substantial mental health benefits beyond simple relaxation.

Sleep Improvement

For better sleep, time your sauna session two to three hours before bed. The temperature drop that occurs after you've heated up and then cooled down mimics your body's natural temperature decline before sleep, which can help you fall asleep faster and sleep more deeply.

Immune System Support

Regular sauna use may strengthen your immune response. The artificial fever your body creates during a session alerts your immune system and triggers natural strengthening mechanisms. For immune support, three to four weekly sessions have shown benefits in reducing the incidence of common colds and respiratory infections.

Skin Health

Heat improves circulation to your skin, opens clogged pores, and helps your body eliminate toxins through sweat. For skin concerns like acne or psoriasis, three to four sessions weekly of 15 to 20 minutes can provide noticeable improvements. The enhanced blood flow also supports collagen production, which helps maintain skin elasticity.

What NOT to Do: The Non-Negotiables

Some mistakes are simply too risky. Follow these rules without exception.

Never Combine Alcohol and Sauna

This is the single most dangerous thing you can do. Alcohol impairs your body's ability to regulate temperature, dramatically increases dehydration risk, and can cause dangerous drops in blood pressure. The combination has resulted in fatalities. Finland reports multiple deaths yearly from people combining alcohol with sauna use.

This applies to the hangover phase as well. Don't use the sauna to "sweat out" alcohol. Wait until you're completely sober and well-hydrated.

Don't Go in When Ill

If you have a fever, infection, or active illness, skip the sauna. The heat adds stress to a body that's already fighting something off. You also risk infecting others who use the sauna after you. Wait until you've fully recovered.

Don't Exceed Safe Time Limits

More is not better. Staying beyond 20 to 30 minutes in a single session increases your risk of dehydration and overheating with no additional benefits. Even experienced users should cap single sessions at 30 minutes maximum.

If you start feeling dizzy, nauseous, get a headache, or feel faint, you've already stayed too long. Exit immediately, cool down, and drink water.

Don't Ignore Your Body's Signals

Your body will tell you when something is wrong. Never push through discomfort in an attempt to prove toughness or match someone else's tolerance. Everyone adapts differently, and what's comfortable for one person might be too much for another.

Don't Bring Electronics

The heat damages phones, tablets, and other electronics. Beyond the device risk, bringing screens into the sauna defeats the purpose of this practice. The sauna should be a sanctuary from digital life.

Don't Skip Cooling Down

Jumping straight from intense heat into vigorous activity or immediately getting dressed and rushing off prevents your body from regulating properly. Always take time to cool down gradually. This is especially important for your cardiovascular system.

For people with heart conditions, plunging into ice-cold water immediately after the sauna can be dangerous. The extreme temperature shock can trigger cardiac events. If you have cardiovascular concerns, stick to gentle cooling methods like cool (not cold) showers or simply sitting in fresh air.

Don't Sit Directly on the Wood

Always use a towel. This is basic sauna etiquette and hygiene. The wood absorbs sweat and oils, so sitting directly on it is unsanitary for everyone who uses the space after you.

Don't Wear Inappropriate Clothing or Accessories

Traditional sauna culture embraces nudity because it's the most effective way to experience the heat. If you prefer to wear something, choose a light cotton towel or swimsuit. Avoid synthetic fabrics that don't breathe.

Remove all jewelry, glasses (they'll fog and heat up), and anything metal that can become hot enough to burn.

Don't Use in Specific Situations

Avoid the sauna if you:

  • Are pregnant (unless your doctor specifically approves)
  • Have uncontrolled high blood pressure
  • Recently had a heart attack
  • Have unstable angina
  • Just completed intense exercise (wait at least 20 to 30 minutes for your heart rate to normalize)
  • Take medications that interfere with temperature regulation or cause drowsiness
  • Have severe kidney disease or conditions that increase dehydration risk

Don't Use the Sauna for Drying Clothes or Objects

Saunas are designed to heat bodies, not objects. Draping wet towels, clothes, or other items over heaters or benches creates fire hazards and can damage your sauna.

Frequently Asked Questions

How long should I stay in the sauna?

Beginners should start with 5 to 10 minutes and gradually work up to 15 to 20 minutes as their bodies adapt. Even experienced users shouldn't exceed 30 minutes in a single session. The Finnish approach is simple: stay until you feel hot enough, then leave. Your body will tell you when it's time.

How often should I use the sauna?

For beginners, once or twice weekly is ideal while your body adapts. Regular users typically enjoy three to four sessions per week. Research shows that four to seven weekly sessions provide the maximum cardiovascular benefits, though even once weekly use offers meaningful health improvements. Listen to your body and maintain consistency rather than pushing for frequency.

Should I shower before and after?

Yes, always shower before entering to remove oils, lotions, and dirt that can block your pores. After your session, showering removes the layer of sweat and helps you cool down gradually. Many people enjoy alternating between warm and cool water afterward.

What should I do between multiple rounds?

Cool down gradually. Step outside into fresh air, take a cool or cold shower, or if you're experienced with contrast therapy, take a brief plunge in cold water. Rest for 10 to 15 minutes, allowing your heart rate to normalize. Drink water. Many people find that sitting quietly during this cooling period is when the deepest relaxation settles in. Once you feel ready and your breathing has returned to normal, you can enter for another round.

Do I need to worry about dehydration?

Yes, but it's easily preventable. Drink 16 to 20 ounces of water 30 to 60 minutes before your session. Keep water nearby during your session. Drink another 16 ounces or more after you finish. Signs of dehydration include dizziness, headache, extreme thirst, and confusion. If you experience these, you've lost too much fluid and need to rehydrate immediately.

Can children use saunas?

Children aged six and above can safely use saunas under adult supervision. Keep their sessions shorter than adults', no more than 15 minutes, and ensure they're on lower benches where temperatures are gentler. Always watch them closely and be ready to exit if they show any discomfort. Very young children under six should avoid saunas as their temperature regulation systems are still developing.

Is the sauna safe during pregnancy?

Most health professionals recommend avoiding saunas during pregnancy. The elevated body temperature can potentially affect fetal development, particularly in the first trimester. If you're pregnant and considering sauna use, discuss it with your healthcare provider first. They may advise against it or, in some cases, approve very brief, cool sessions.
