The main difference in the steam room vs sauna debate is the type of heat. A traditional sauna uses very hot, dry air, while a steam room uses lower temperatures with air that is almost fully saturated with moisture. Both make you sweat and feel relaxed; which one suits you depends on how you handle heat, how your airways feel in humid air, and any health conditions you have.
Key takeaways
- A sauna is hot and dry (often about 70–90°C, with low humidity); a steam room is cooler (usually around 40–50°C) but close to 100% humidity.
- Both raise heart rate and skin temperature and can feel relaxing after training, but neither “detoxes” the body or burns meaningful fat.
- Most healthy adults can use either for short sessions; Harvard Health suggests staying in a sauna no more than 15–20 minutes, with water afterwards.
- Avoid both after alcohol, when unwell, or if you have unstable heart problems, very low blood pressure or are pregnant, unless your doctor says it is fine.
- If you have access to both, try each on separate days and see which one your body tolerates better.
What is the difference between a steam room and a sauna?
A sauna heats the air to a high temperature with very little moisture, while a steam room fills the space with water vapour at a lower temperature. The experience feels very different even though both make you sweat.
How a sauna works
A traditional Finnish-style sauna uses a heater, often with stones, to warm the room. Air temperatures are commonly in the 70–90°C range, and humidity stays low unless water is ladled onto the stones. Because the air is dry, sweat evaporates quickly from your skin, which is why many people can tolerate the high number on the thermometer.
How a steam room works
A steam room is fed by a steam generator. The temperature is much lower, usually around 40–50°C, but the humidity is close to 100%. Sweat cannot evaporate in saturated air, so it drips off the skin, and the room can feel hotter than the temperature suggests. Many people find breathing in warm, moist air soothing; others find it stuffy.
What are the benefits of a sauna?
The best-supported benefits of a sauna are relaxation and a short-term feeling of loosened muscles, along with some promising research on heart health from regular, long-term use. It is not a weight-loss tool.
According to Harvard Health Publishing, dry sauna heat can reach about 85°C and your pulse rate can jump by 30% or more, so the heart pumps much more blood each minute. That is why a session can feel a little like light exercise. Observational studies, mostly from Finland, have linked frequent sauna bathing with better heart health, but these studies show associations, not proof that the sauna itself causes the benefit.
Commonly reported effects include:
- A calm, relaxed feeling and better sleep for some people.
- Temporary relief from muscle stiffness after training.
- A pleasant routine that encourages people to rest between workouts.
Any weight you “lose” in a sauna is water from sweating. It returns as soon as you rehydrate. You can read more about how we use it at Spark3Fitness on our page on the benefits of sauna.
What are the benefits of a steam room?
The main benefits of a steam room are relaxation and comfort for the airways and skin, as warm, moist air can feel soothing. Like the sauna, it does not remove “toxins” or burn fat.
People often say a steam room:
- Feels gentler on the nose and throat than dry heat.
- Helps them unwind after a long day or a hard session.
- Leaves skin feeling soft and warm, as pores open with heat and moisture.
Steam rooms are shared, warm and damp, so hygiene matters. Sit on a towel, shower before and after, and wear clean footwear in wet areas. If you have a respiratory condition such as asthma, check with your doctor, because some people find humid heat comfortable while others find it harder to breathe. Our page on the benefits of steam room explains how members use it.
Steam room vs sauna: which is better for you?
Neither is better for everyone. Choose a sauna if you like intense dry heat and short sessions; choose a steam room if you prefer lower temperatures and moist air. The table below sums up the main differences.
| Feature | Sauna | Steam room |
|---|---|---|
| Type of heat | Dry heat | Moist heat (steam) |
| Typical temperature | About 70–90°C | About 40–50°C |
| Humidity | Low (rises if water is poured on stones) | Close to 100% |
| How sweat behaves | Evaporates quickly | Drips; cannot evaporate |
| Often preferred by | People who like intense, dry heat | People who like gentler, humid heat |
| Typical session | 10–20 minutes | 10–15 minutes |
| Main cautions | Dehydration, dizziness, heart strain | Dehydration, dizziness, hygiene, breathing discomfort for some |
A simple way to decide is to try each one on separate days, keeping sessions short at first. Notice how you feel during and after: light-headedness, a pounding heart or nausea are signs to stop.
Is it good to use a sauna after a workout?
Using a sauna after a workout is fine for most healthy adults, as long as you cool down and drink water first. The risk is adding heat stress on top of exercise, when you are already sweating and possibly low on fluids.
Follow these steps for a safe sauna after workout routine:
- Finish your session with a 5–10 minute cool-down and stretch.
- Drink a glass or two of water before you go in.
- Shower and dry off, then sit in the sauna or steam room for 5–10 minutes the first few times.
- Build up gradually to 15–20 minutes at most if you feel comfortable.
- Leave immediately if you feel dizzy, sick or unusually breathless.
- Cool down slowly, shower, and drink more water afterwards; Harvard Health suggests two to four glasses of cool water after each sauna.
Avoid going in straight after very intense training, such as a hard HIIT class, when your heart rate is still high. Give yourself time to settle first. Never use heat to “sweat off” weight before weighing yourself; it only dehydrates you.
When should you check with a doctor first?
Talk to your doctor before using a sauna or steam room if you have a heart condition, blood pressure problems, are pregnant or have any long-term illness. Heat places extra demand on your heart and circulation.
Be especially careful, and get medical advice first, if you:
- Have unstable angina, a recent heart attack or a serious heart valve problem.
- Have very low or poorly controlled high blood pressure, or take medicines that affect blood pressure.
- Are pregnant.
- Have epilepsy, diabetes with nerve or circulation problems, or a respiratory condition.
- Are recovering from an illness, fever or injury.
- Have had alcohol, or take medicines that affect sweating or cause overheating. Harvard Health advises avoiding both before and after a sauna, and says anyone who is ill should not use one.

How do you use a gym sauna or steam room safely?
Keep sessions short, stay hydrated, and listen to your body. Simple etiquette also keeps the space pleasant for everyone.
- Go in well hydrated, never on an empty stomach or after a heavy meal.
- Shower before entering and sit on a towel.
- Remove jewellery, which can get very hot.
- Keep your phone out; heat and moisture damage electronics.
- Do not go in alone if you are unsure how you will react.
- Step out and cool down at the first sign of feeling unwell.

Frequently asked questions
Which is better, a steam room or a sauna?
Neither is better for everyone. A sauna offers hot, dry heat, while a steam room offers lower but very humid heat, so choose the one you find more comfortable and can use safely.
How long should I sit in a sauna or steam room?
Most healthy adults should start with 5–10 minutes and stay no longer than 15–20 minutes. Leave straight away if you feel dizzy, sick or breathless.
Does a sauna help with weight loss?
No, not in any meaningful way. The weight you lose in a sauna is water from sweat, and it comes back when you drink fluids.
Can I use the sauna and steam room on the same day?
Many people do, but it adds up to more heat stress. Keep each session short, take a cool-down break with water in between, and stop if you feel unwell.
Who should avoid saunas and steam rooms?
People who are pregnant, have heart problems, very low or uncontrolled blood pressure, or have been drinking alcohol should avoid them unless a doctor has advised that it is safe.
