Editorial and medical disclosure: Sauna & Steam Center sells, designs, installs, services, and repairs sauna systems. This guide is educational and is not medical advice. Sauna heat can affect hydration, heart rate, blood pressure, and heat tolerance. Follow the manufacturer instructions and posted facility rules for the sauna you are using. Seek individualized medical guidance if you are pregnant, have cardiovascular or blood-pressure concerns, faint easily, have fluid restrictions, or take medications that affect hydration, sweating, alertness, or heat tolerance.

How to use a sauna properly: hydrate before you start, enter clean and comfortable, begin with a short session, sit or lie down and relax, monitor how you feel, leave before the heat becomes uncomfortable, cool down gradually, and drink water afterward. If it is your first time using a sauna, the goal is not to tolerate the hottest temperature or longest session. The goal is to learn how your body responds and develop a routine you can comfortably repeat.

Quick answer: The best way to use a sauna is to keep the routine simple. Drink water beforehand, shower or rinse if practical, remove jewelry and heat-sensitive electronics, sit on a towel, start on a lower bench or milder setting, relax instead of exercising, and leave immediately if you feel dizzy, weak, nauseated, faint, unusually short of breath, confused, or excessively hot. Beginners can start with a short session and increase gradually only when previous sessions feel comfortable. Cool down afterward and replace fluids lost through sweating.

If you searched for how to use a sauna, what to do in a sauna, how to sauna, how to work a sauna, or the proper way to use a sauna, you are probably looking for practical instructions rather than a complicated wellness protocol.

This guide walks through the entire experience, including how to start a sauna, what to do before entering, what you actually do while sitting inside, beginner timing and temperature, traditional versus infrared use, water on sauna rocks, cooling down, home-sauna operation, gym etiquette, common mistakes, and when to leave immediately.

Beginner rule: Sauna use should feel challenging enough to be warm, but not like something you have to endure. You do not need to prove that you can tolerate a certain temperature or session length.

Key Takeaways for Sauna Beginners

Start with a short, comfortable session rather than trying to reach a specific maximum time.
Hydrate before and after because sweating increases fluid loss.
Sit or lie down and relax. The sauna itself is the activity.
A lower bench usually feels cooler than an upper bench in a traditional sauna.
Do not exercise hard inside the room.
Avoid alcohol before and during sauna use.
Do not enter already dehydrated, overheated, feverish, or acutely ill.
Only pour water on rocks when the traditional heater and facility rules specifically allow it.
Traditional and infrared saunas operate differently, so do not apply one system’s instructions to the other.
Home controls vary by manufacturer. The exact heater manual always takes priority over generic instructions.
Leave immediately if you feel faint, dizzy, confused, nauseated, unusually weak, short of breath, or excessively hot.

How to Use a Sauna Step by Step

If you only remember one part of this guide, use this routine.

Step	What to Do	Why It Matters
1. Hydrate	Drink water before entering.	Sweating increases fluid loss.
2. Prepare	Shower or rinse if practical, dry off, remove jewelry and electronics, and bring a towel.	Improves hygiene, comfort, and equipment protection.
3. Start Mild	Use a lower bench or moderate setting if you are new.	Allows you to learn your heat tolerance gradually.
4. Sit on a Towel	Place a clean towel between your body and the bench.	Improves hygiene and keeps benches cleaner.
5. Relax	Sit or lie down, breathe normally, and let the heat do the work.	Hard exercise adds unnecessary physical stress.
6. Monitor Yourself	Pay attention to dizziness, nausea, unusual weakness, breathing difficulty, or excessive discomfort.	Your body is a better guide than a timer.
7. Leave Before You Need To	Exit while you still feel reasonably comfortable.	You do not need to stay until the heat becomes unpleasant.
8. Cool Down	Spend a few minutes in a cooler environment.	Allows body temperature and heart rate to settle.
9. Rehydrate	Drink water afterward.	Helps replace fluid lost through sweating.
10. Shower and Recover	Rinse off sweat and rest briefly.	Completes the session comfortably.

The proper sauna routine: Hydrate, prepare, heat, relax, listen to your body, cool down, and rehydrate.

What Should You Do Before Using a Sauna?

Hydrate Normally

Do not enter already dehydrated.

This is particularly important after exercise, outdoor work, travel, or any activity that has already caused significant sweating.

Shower or Rinse

A quick shower can remove sweat, lotion, deodorant, dirt, and excess body products.

In a shared facility, showering first is often part of basic etiquette. At home, it can also help keep the wood and benches cleaner.

Dry Off

Entering dry can make the experience more comfortable and reduce unnecessary water on wooden surfaces.

Remove Jewelry

Metal jewelry can become uncomfortable when heated.

Leave Electronics Outside

Phones, smartwatches, earbuds, and other electronics may not tolerate sauna temperatures.

For more detail, read our guide to phones and electronics in a sauna.

Avoid Alcohol

Alcohol can increase dehydration and can make it harder to recognize when heat exposure is becoming excessive.

Do Not Sauna if You Are Already Overheated or Ill

A fever, significant dehydration, or acute illness is not the time to add additional heat stress.

How Do You Start and Work a Sauna?

People searching for how to work a sauna or how to start a sauna may literally be asking how to turn the equipment on.

There is no universal button sequence because heater systems and controls differ.

General Home Sauna Startup Sequence

Inspect the heater area. Make sure towels, clothing, cleaning supplies, and other objects are not resting on or too close to the heater.
Check ventilation openings. Do not intentionally block vents.
Turn the system on. Use the approved wall control, built-in control, or manufacturer-supported app.
Select the temperature. Stay within the manufacturer-approved operating range.
Set the timer. Use the operating or delay timer according to the control manual.
Allow preheating when required. Traditional saunas generally need time for the room and rocks to warm.
Confirm normal operation. Make sure the system is heating normally before entering.
Use the sauna. Follow the heat, timing, and water instructions for that system.
Shut down correctly. Turn the system off or confirm that its timer has ended.
Allow the room to dry. Remove wet towels and follow your ventilation and maintenance instructions.

Never bypass safety controls: Do not cover temperature sensors, defeat high-limit devices, modify required heater clearances, or use a startup procedure that contradicts the manufacturer’s manual.

Why Exact Instructions Vary

Harvia, Finnleo, HUUM, Tylo, Saunum, and other manufacturers use different controllers, timers, sensors, apps, and operating sequences.

If you own the sauna, keep the exact heater and controller manual accessible.

How to Use a Sauna for the First Time

Your first sauna should be treated as an introduction rather than a test of endurance.

You are learning three things:

How the heat feels
Which bench level feels comfortable
How your body responds during and after the session

First-Time Sauna Checklist

Drink water before entering.
Avoid alcohol beforehand.
Shower or rinse if practical.
Remove jewelry and electronics.
Bring a clean towel.
Use a lower bench or milder setting.
Begin with a short session.
Leave earlier whenever you want.
Cool down gradually.
Drink water afterward.
Notice how you feel over the next few minutes before deciding whether you want another heat cycle.

Your first sauna is a learning session: You are discovering the amount of heat and time that feels comfortable to you. There is no prize for tolerating more than someone else.

What Do You Actually Do in a Sauna?

What to do in a sauna: Sit or lie down comfortably, breathe normally, relax, enjoy the heat, and pay attention to how you feel. You can talk quietly, meditate, stretch very gently, or simply sit still. You do not need to exercise, force yourself to sweat, or perform a special routine.

Good Things to Do

Sit or lie comfortably.
Use a towel under your body.
Breathe normally.
Relax your shoulders, neck, and jaw.
Enjoy a quiet break from screens.
Move lower if the heat feels too strong.
Move higher only if you intentionally want more heat and feel comfortable.
Leave before you feel pushed to your limit.

Things You Do Not Need to Do

Push-ups
Cardio
Hard stretching
Breath-holding challenges
Trying to sweat as much as possible
Staying until a timer forces you out
Using your phone

Can You Meditate in a Sauna?

Yes, if sitting quietly helps you relax.

Keep breathing normal and avoid breath-holding practices that could make dizziness harder to recognize.

Can You Stretch in a Sauna?

Gentle movement may feel comfortable, but aggressive stretching is unnecessary. Heat can change how flexible you feel, so avoid forcing a range of motion simply because muscles feel warm.

What Should You Wear in a Sauna?

What you wear depends on whether you are at home, a gym, spa, hotel, or public facility.

At Home

Use whatever is comfortable and appropriate for your household, while placing a clean towel between your body and the bench.

At a Gym or Spa

Follow the facility’s clothing rules. Depending on the location, this may mean a towel, swimsuit, or other appropriate clothing.

What to Avoid

Heavy clothing
Metal jewelry
Heat-sensitive electronics
Shoes unless specifically required
Products with strong fragrances
Items that could melt, warp, or become excessively hot

Simple rule: Wear as little as the setting appropriately allows, use a towel on the bench, and follow facility rules.

How Long Should You Stay in a Sauna?

There is no single perfect session length for every person, temperature, and sauna type.

First-time users should begin conservatively and increase only when previous sessions have felt comfortable.

Experience	Practical Approach
First session	Keep it short and use the session to learn how the heat feels.
New user	Increase gradually only when earlier sessions felt comfortable during and afterward.
Regular user	Continue following the sauna type, temperature, manufacturer guidance, and personal tolerance.

General consumer guidance commonly discusses sessions in the range of approximately 15 to 20 minutes, but that should never be treated as a mandatory target.

For a deeper explanation, see our guide to sauna session length.

Timing rule: Leave sooner whenever the heat stops feeling comfortable. A timer is not more important than how you feel.

What Temperature Should a Beginner Use?

The correct temperature depends heavily on the type of sauna.

Traditional Sauna

Traditional saunas can operate at significantly higher air temperatures than infrared systems.

A beginner can make the experience milder by using a lower bench and avoiding the highest temperature setting.

Infrared Sauna

Infrared saunas generally operate at lower ambient air temperatures while delivering radiant heat from infrared emitters.

Beginners should still start conservatively and increase heat or time only as comfort allows.

Do Not Chase the Maximum Setting

A hotter room is not automatically a better session.

Temperature, duration, bench height, humidity, and individual tolerance all interact.

For detailed ranges by sauna type, see our sauna temperature guide.

Which Bench Should a Beginner Use?

Traditional sauna rooms commonly have multiple bench heights.

Hot air rises, so upper benches generally feel hotter than lower benches.

Bench Position	Typical Experience
Lower bench	Milder heat and a good starting point for beginners.
Middle position	Moderate heat in larger multi-level rooms.
Upper bench	Hotter environment for users who intentionally prefer more heat.

If the room feels too intense, moving lower can be more comfortable than trying to tolerate the hottest position.

How to Use a Traditional Sauna vs. an Infrared Sauna

The basic hydration, comfort, and safety routine is similar, but the equipment and experience differ.

Feature	Traditional Sauna	Infrared Sauna
How heat is produced	Heater warms the room and sauna rocks	Infrared emitters provide radiant heat
Air temperature	Generally higher	Generally lower
Preheating	Usually required	Depends on manufacturer and system
Water on rocks	May be allowed when heater is designed for it	Not applicable to infrared panels
Bench height effect	Upper levels usually hotter	Heat distribution works differently depending on emitter placement
Beginner strategy	Lower bench, moderate heat, short initial exposure	Conservative temperature and time, then increase gradually

Do not mix operating instructions: Never pour water onto infrared emitters or assume that a traditional sauna operating method applies to an infrared cabin.

Can You Pour Water on Sauna Rocks?

Only when the heater is specifically designed for water use.

In a traditional Finnish-style sauna with approved stones, a small amount of water can be poured over the heated rocks to create löyly, a temporary increase in humidity and perceived heat.

Do Not Pour Water On:

Infrared panels
Control panels
Electrical components
A heater not designed for water
A shared gym or hotel heater when rules prohibit it

When in doubt, do not add water. Check the heater manual or posted facility rules first.

What Should You Do After a Sauna?

1. Cool Down Gradually

Move to a comfortable environment and allow your heart rate and body temperature to settle.

2. Drink Water

Replace fluid after sweating, particularly if you exercised beforehand.

3. Shower

A shower can rinse away sweat and help you feel refreshed.

You do not need to force an extremely cold shower simply because you used heat.

4. Rest Briefly

Give yourself a few minutes to notice how you feel before returning to strenuous exercise or another intense heat exposure.

5. Eat Normally

If the sauna was part of a workout or long wellness session, resume normal food and hydration according to your usual needs.

After-sauna routine: Cool down, rehydrate, rinse off, and give your body a few minutes to settle.

How to Use a Home Sauna

A home sauna follows the same basic user routine, but ownership also gives you responsibility for the heater, controls, room drying, and maintenance.

Before Each Home Sauna Session

Check that the heater area is clear.
Make sure towels and clothing are not touching the heater.
Check that air openings are not blocked.
Use the approved control system.
Set temperature and timer according to the manual.
Allow proper preheating if required.

During the Session

Use a towel on the bench.
Do not cover sensors.
Do not hang towels over the heater.
Use water only if the heater allows it.
Keep the exit accessible.
Follow the heater’s operating limits.

After the Session

Turn the system off or confirm automatic shutdown.
Remove wet towels.
Allow the room to ventilate and dry.
Wipe benches when needed.
Inspect the room periodically.
Follow wood, rock, heater, and control maintenance instructions.

If you are considering ownership, see our home sauna guide.

How to Use a Sauna at a Gym or Spa

A public or shared sauna adds etiquette and facility rules to the basic routine.

Shower first when required.
Wear whatever the facility rules require.
Sit on a clean towel.
Keep conversation at a respectful volume.
Do not play music or videos aloud.
Leave electronics outside.
Do not shave or groom inside.
Avoid applying strong fragrances.
Do not pour water on the heater unless explicitly allowed.
Respect occupancy limits.
Follow posted time and temperature rules.

Facility rules win: Even if your home heater allows water on rocks or a certain operating routine, the gym, hotel, or spa may prohibit it.

How Often Should a Beginner Use a Sauna?

There is no universal beginner schedule that everyone must follow.

A practical approach is to begin with occasional short sessions and increase only when:

You tolerate the heat comfortably.
You remain well hydrated.
You feel normal after sessions.
The routine feels relaxing instead of draining.
You have enough time to cool down and recover.

Consistency matters more than forcing a high frequency immediately.

Should You Eat or Drink Before Using a Sauna?

Water

Being normally hydrated before the session is more important than drinking an extreme amount of water immediately beforehand.

Heavy Meals

A very large meal immediately before intense heat may feel uncomfortable for some people. Give yourself enough time to feel comfortable before entering.

Alcohol

Avoid alcohol around sauna use because it can increase dehydration and interfere with awareness of heat-related symptoms.

Caffeine

Individual tolerance varies. The main concern is entering the sauna already dehydrated or feeling overstimulated or unwell.

Simple approach: Use the sauna normally hydrated and reasonably comfortable rather than extremely full, dehydrated, or under the influence of alcohol.

Should You Use a Sauna Before or After a Workout?

Many people prefer sauna use after exercise because it can serve as part of a cooldown and relaxation routine.

However, exercise itself can already increase body temperature and fluid loss.

If you sauna after a workout:

Allow your heart rate to begin settling.
Replace some fluid first when needed.
Use a conservative session if the workout was demanding.
Do not treat sauna sweating as an extension of the workout.

Using intense heat before hard exercise can also affect hydration and comfort.

For workout-specific guidance, see our sauna after the gym guide.

Common Sauna Mistakes Beginners Should Avoid

Mistake	Better Approach
Staying until the heat becomes unbearable	Leave while you still feel reasonably comfortable.
Starting on the hottest bench	Begin lower and move higher only if desired.
Entering dehydrated	Hydrate normally before and after.
Using alcohol before sauna	Avoid alcohol around the session.
Exercising hard inside	Use the sauna for heat and relaxation.
Trying to force maximum sweating	Let sweating occur naturally.
Bringing electronics	Leave heat-sensitive electronics outside.
Pouring water on every heater	Add water only when the heater and facility rules allow it.
Copying someone else’s routine	Build your own tolerance gradually.
Ignoring dizziness or nausea	Exit immediately.
Assuming hotter is always better	Choose a heat level that you can comfortably repeat.
Blocking vents or sensors	Leave safety and ventilation components unobstructed.

When Should You Leave a Sauna?

You can leave whenever you have had enough. You do not need to wait for a timer.

Leave immediately if you experience:

Dizziness
Feeling faint
Nausea
Unusual weakness
Confusion
Difficulty breathing
Chest discomfort
Severe headache
Loss of coordination
Excessive heat discomfort

Who Should Be More Careful With Sauna Use?

Individualized professional guidance may be appropriate for people with:

Heart disease or recent cardiac symptoms
High or low blood-pressure concerns
A history of fainting
Pregnancy
Kidney disease or fluid restrictions
Heat intolerance
Neurologic conditions affected by heat
Medications that affect sweating, hydration, alertness, or blood pressure

Seek appropriate medical help if severe dizziness, fainting, confusion, difficulty breathing, chest discomfort, or another concerning symptom does not resolve promptly after leaving the heat.

What Is the Best Way to Use a Sauna for Beginners?

The best beginner routine is not the hottest or longest one.

A useful routine looks like this:

Arrive normally hydrated.
Shower or rinse if appropriate.
Remove electronics and jewelry.
Start at a comfortable heat level.
Use a towel on the bench.
Sit quietly and breathe normally.
Move lower if the heat feels too intense.
Leave before you become uncomfortable.
Cool down gradually.
Drink water.
Notice how you feel afterward.
Adjust the next session based on your experience.

Best sauna routine: A routine you enjoy, tolerate well, and can repeat safely is more useful than an extreme routine you dread.
