Saunas offer a time-honored way to relax, recover, and support overall wellbeing. With both traditional (Finnish) and infrared options available, choosing the right type depends on your preferences, space, budget, and health goals. This guide explains the differences, benefits, and trade-offs of each to help you make an informed decision.
Saunas have been valued for centuries for their restorative and relaxation effects. Modern developments introduced infrared saunas, which use a different heating method and offer an alternative sauna experience that may better suit some users.
What Is a Traditional Sauna?
A traditional, or Finnish, sauna is a wooden room heated by a stove or electric heater that warms the air. Temperatures typically range between 150°F and 195°F, while humidity is usually low unless water is poured over hot stones to create steam. The high dry heat promotes sweating, muscle relaxation, and circulatory benefits, and traditional saunas are often large enough for multiple people to sit and socialize.
What Is an Infrared Sauna?
Infrared saunas heat the body directly using infrared light rather than first heating the surrounding air. They typically operate at lower air temperatures—commonly between 120°F and 150°F—yet still encourage sweating by raising the body’s core temperature. Infrared units are usually more compact and built from materials like wood with infrared heating panels; some designs incorporate glass or metal elements. These saunas can be used dry or with added steam depending on the model.
Benefits of Traditional Saunas
Traditional saunas are well established and associated with many health and wellness benefits. Regular use can help ease joint and muscle stiffness, promote circulation, support immune function, and reduce stress. The hot, dry environment also tends to enhance skin cleansing through sweating and provides a relaxing ritual that many people find mentally restorative.
Pros of Traditional Saunas
- Evidence-Based Benefits: Traditional saunas have a long history and a substantial body of research supporting improvements in circulation, relaxation, and post-exercise recovery.
- Social and Communal: Larger sauna rooms allow multiple users, making them well suited to social or family use and shared relaxation sessions.
- Aromatherapy Options: Adding water, essential oils, or herbs to the stove enhances the sensory experience and can provide additional inhalation-based therapeutic effects.
Cons of Traditional Saunas
- Higher Energy Use: Heating the air to high temperatures requires more energy, which can increase operating costs.
- Longer Warm-Up Time: Traditional saunas take longer to reach optimal temperature, which can be less convenient for shorter sessions.
- Installation Needs: Building a traditional sauna often involves more complex installation, including proper ventilation, insulation, and space considerations.
Benefits of Infrared Saunas
Infrared saunas have gained popularity for their distinctive heating method and perceived health advantages. They promote sweating and a rise in core temperature at lower ambient air temperatures, which some users find more comfortable. Infrared sessions are often associated with detoxification, reduced inflammation, improved skin tone, and cardiovascular support. Because they operate at lower temperatures, they can be more accessible to people who find high heat uncomfortable.
Pros of Infrared Saunas
- Energy Efficiency: Infrared units typically use less energy and heat up faster than traditional saunas, reducing wait times and operating costs.
- Lower Air Temperatures: Operating at lower ambient temperatures (often 110°F–140°F) can make sessions more tolerable for those sensitive to intense heat.
- Deeper Heat Penetration: Infrared wavelengths are designed to penetrate deeper into tissues, which proponents say supports thorough sweating and muscle relief.
- Simpler Installation: Infrared saunas tend to be easier to install and require fewer structural modifications, as they don’t need the same ventilation or heavy-duty heating infrastructure as traditional saunas.
Cons of Infrared Saunas
- Less Long-Term Research: Although growing in popularity, infrared saunas have less long-term research compared with traditional saunas, so some health claims need further study.
- Upfront Cost: Some infrared models can have a higher initial purchase price and may require ongoing maintenance costs depending on the build and components.
How to Choose Between Them
Choosing the right sauna depends on what you value most: traditional high-heat and steam experiences, or lower-temperature infrared sessions that heat the body directly. Consider comfort level with heat, desired health outcomes (detox, cardiovascular benefits, muscle recovery), available space, and budget when making your choice.
Traditional saunas offer a classic, communal atmosphere and well-documented benefits but generally require more energy and installation effort. Infrared saunas provide quicker warm-up, easier installation, and a gentler ambient temperature that can still deliver significant therapeutic effects.
To help narrow your options, evaluate these practical factors:
- Space Requirements: Measure available space. Infrared saunas are often compact and suitable for smaller rooms, while traditional saunas typically require more room and ventilation.
- Budget Considerations: Compare upfront purchase and installation costs as well as ongoing energy and maintenance expenses. Infrared models may save on operational costs, while traditional builds may have higher energy bills and installation complexity.
- Personal Health Goals: Align the sauna’s strengths with your priorities. Choose infrared for deep tissue warming and comfort at lower air temperatures; choose traditional if you prefer very high heat, steam options, and a communal sauna environment.
Both traditional and infrared saunas provide valuable health and relaxation benefits. The best choice is the one that fits your lifestyle, comfort preferences, space, and budget. Consider trying both types if possible to determine which experience you prefer before committing to a purchase or installation.
