Infrared saunas use light to heat the body directly, promoting detoxification and relaxation, while traditional saunas heat the air, providing a more humid experience.
Saunas have been used for centuries to promote relaxation, detoxification, and overall wellness. Today, two main types dominate the market: infrared and traditional saunas. While both offer health benefits, they work in fundamentally different ways. This guide breaks down the key differences to help you choose the best option for your needs.
How Traditional Saunas Work
Traditional saunas, also known as Finnish saunas, use a heat source to warm the air around you. These typically operate at temperatures between 150°F and 190°F. The heat source can be:
- Wood-burning stoves (most authentic)
- Electric heaters (most common in modern installations)
- Gas heaters
Many users add humidity by pouring water over heated rocks, creating steam. This process is called “löyly” in Finnish tradition. The high temperatures cause your core body temperature to rise, triggering profuse sweating.
Traditional Sauna Experience
A typical session lasts 15-30 minutes. Users often alternate between heat exposure and cooling periods. The intense heat creates a bracing experience that some describe as invigorating but others find overwhelming.
How Infrared Saunas Work
Infrared saunas use light waves to directly heat your body rather than the surrounding air. These operate at lower temperatures (120°F-150°F) while still inducing sweat. The infrared spectrum includes:
| Type | Wavelength | Penetration Depth |
|---|---|---|
| Near-infrared | 700-1400 nm | Superficial (skin level) |
| Mid-infrared | 1400-3000 nm | Deeper tissue |
| Far-infrared | 3000 nm-1 mm | Deepest penetration |
Most home infrared saunas use far-infrared technology. Unlike traditional saunas, you won’t experience the same intense ambient heat, making sessions more comfortable for longer durations.
Key Differences Compared
Heat Delivery Mechanism
Traditional saunas heat the air which then heats your body through convection. Infrared saunas use radiant heat that penetrates tissue directly. This explains why you can sweat profusely at lower ambient temperatures in an infrared unit.
Temperature Range
Traditional: 150-190°F
Infrared: 120-150°F
Energy Efficiency
Infrared saunas typically use less energy since they don’t need to heat the entire air volume. According to Harvard Health, infrared units can be 30-50% more efficient.
Installation Requirements
Traditional saunas often require:
– Ventilation systems
– Waterproof construction
– Significant space
Infrared units can be simpler to install, with some models being portable or fitting in smaller spaces. For those considering home installation, our guide on built-in heating solutions offers helpful insights.
Health Benefits Comparison
Both sauna types offer similar health benefits, though research suggests some differences in effectiveness for specific conditions:
Cardiovascular Health
Studies show both types improve circulation and heart health. A JAMA study found traditional sauna use 4-7 times weekly reduced cardiovascular mortality by 50%.
Pain Relief
Infrared’s deeper tissue penetration may be more effective for:
– Muscle soreness
– Joint pain
– Arthritis symptoms
Detoxification
Both promote sweating, but infrared may facilitate greater toxin elimination at cellular levels due to deeper heating.
Skin Health
Infrared light stimulates collagen production and may improve skin elasticity more than traditional heat alone.
Safety Considerations
Traditional Sauna Risks
- Higher risk of overheating/dehydration
- Can exacerbate respiratory issues in humid conditions
- Not recommended for those with heart conditions
Infrared Sauna Risks
- Potential EMF exposure (varies by model)
- May interact with certain medications
- Possible light sensitivity issues

Which Should You Choose?
Consider an infrared sauna if you:
– Prefer lower temperatures
– Want deeper tissue penetration
– Need a more compact solution
– Seek energy efficiency
Consider a traditional sauna if you:
– Enjoy the classic sauna experience
– Prefer higher heat/humidity
– Have space for proper installation
– Value cultural traditions
Both options provide excellent health benefits when used properly. The best choice depends on your personal preferences, health status, and available space. Always consult your doctor before beginning any new heat therapy regimen, especially if you have pre-existing medical conditions.
