What is a Sauna?
A sauna is a small room or enclosed space designed to be heated to high temperatures, typically between 150°F to 195°F (65°C to 90°C), for the purpose of relaxation, detoxification, and overall wellness. The practice of using saunas dates back thousands of years and has been a staple in cultures across the globe, especially in Scandinavian countries like Finland.
A Brief History of Saunas
The concept of heat therapy is not new. Ancient civilizations such as the Greeks and Romans had bathhouses and steam rooms. However, the modern sauna as we know it has its roots in Finland, where people have been using saunas for over 2,000 years. Traditionally, Finnish saunas were made from wood and heated by burning wood in a stove with stones placed on top. Over time, the methods evolved to include electric heaters and infrared technology.
Types of Saunas
Traditional Finnish Sauna
This is the most classic form of sauna, usually made from wood and heated with a wood-burning or electric stove. Stones are placed on top of the stove, and water can be poured over them to create steam and increase humidity.
Infrared Sauna
Instead of heating the air, infrared saunas use infrared light to warm your body directly. This allows for lower temperatures while still providing deep tissue heat. They are particularly popular for their perceived benefits in muscle recovery and detoxification.
Steam Room (Wet Sauna)
While technically not a sauna, steam rooms are often grouped under the same category. They use a steam generator to create a humid environment with temperatures usually lower than dry saunas, around 110°F to 120°F (43°C to 49°C).
Portable Sauna
These are convenient, often tent-like structures that can be set up at home. They are typically infrared saunas and are ideal for people who want a sauna experience without investing in a full-sized unit.
Smoke Sauna
A traditional Finnish variation, smoke saunas use wood fire without a chimney. The smoke fills the room and is then ventilated before use. The residual heat and unique aroma provide a distinctive experience.
Health Benefits of Using a Sauna
Detoxification
Sweating is the body’s natural way to eliminate toxins. Saunas enhance this process by encouraging intense perspiration, helping to flush out heavy metals and chemicals.
Improved Circulation
The heat causes blood vessels to dilate, which improves circulation. This can help reduce muscle soreness, promote healing, and improve cardiovascular health.
Skin Health
The sweating process opens up pores, helping to clear out impurities and dead skin cells. Regular sauna use can result in clearer, healthier-looking skin.
Mental Health and Relaxation
Saunas are known for their calming effects. The heat helps reduce stress hormones like cortisol and promotes the release of endorphins, making you feel more relaxed and happier.
Pain Relief
Heat therapy has long been used to relieve joint and muscle pain. Saunas can be particularly helpful for people with arthritis or chronic pain conditions.
Weight Loss Support
While not a replacement for exercise, sauna use can slightly increase calorie burn through elevated heart rate and sweating.
Immune System Boost
Some studies suggest that regular sauna sessions can increase white blood cell count, enhancing the body’s ability to fight off infections.
How to Use a Sauna Safely
Preparation
- Hydrate: Drink plenty of water before entering the sauna.
- Shower: A quick rinse helps to remove oils and dirt, keeping the sauna clean.
- Clothing: Wear a towel or go nude, depending on cultural norms and personal comfort.
During the Session
- Time Limit: Beginners should start with 5-10 minutes. Experienced users can stay for up to 20-30 minutes.
- Listen to Your Body: If you feel dizzy, lightheaded, or unwell, exit the sauna immediately.
- Use a Timer: To avoid losing track of time.
Aftercare

- Rest: Allow your body to recover and avoid intense activity immediately afterward.
Common Sauna Myths
Myth 1: Saunas Help You Lose Fat
While you might lose water weight through sweating, saunas do not directly burn fat. Long-term weight loss requires a balanced diet and exercise.
Myth 2: More Time Equals More Benefits
Overstaying in a sauna can lead to dehydration and heat-related illnesses. More is not always better.
Myth 3: Saunas Are Only for Relaxation
Though relaxation is a key benefit, saunas also offer therapeutic advantages like improved circulation and detoxification.
Myth 4: Infrared Saunas Are Less Effective
Infrared saunas provide different benefits. They penetrate deeper into the skin and muscles, making them effective for pain relief and detoxification at lower temperatures.
Cultural Significance of Saunas
Finland
In Finland, the sauna is a way of life. With a population of around 5.5 million people and over 3 million saunas, they are used for both social and solitary activities.
Russia
The Russian “banya” is similar to a sauna and is an integral part of their wellness culture. It often includes a tradition of being gently beaten with birch branches to stimulate circulation.
Japan
While not called saunas, Japanese bathhouses (sento or onsen) often incorporate steam and heat therapy as part of their ritual.
Native American Sweat Lodges
These are spiritual ceremonies involving a dome-shaped structure and heated stones, combining physical detoxification with spiritual renewal.
Sauna Etiquette
Cleanliness
Always shower before entering and sit on a towel to avoid getting the bench wet with sweat.
Silence or Quiet Conversation
Saunas are generally places of peace. Loud talking or phone use is discouraged.
Respect Time Limits
If others are waiting, keep your sessions reasonable.
Be Considerate with Scents
Avoid heavy perfumes or scented lotions that might affect others.
