Infrared Saunas: An Expert’s Guide
What Is an Infrared Sauna?
Infrared saunas represent a revolutionary advancement in wellness technology, offering a more effective and comfortable alternative to traditional saunas. Unlike conventional saunas that rely on heating the air around you, infrared saunas infrared waves that directly warms your body, similar to how the sun naturally warms your skin on a pleasant day.
Infrared vs Traditional Sauna: Why Far Infrared Excels
Traditional saunas operate at extremely high temperatures between 150°F to 195+°F, making them uncomfortable for many users. In contrast, far infrared saunas deliver therapeutic benefits at much more comfortable temperatures of 100°F to 158°F. This fundamental difference creates several advantages:
- More comfortable heating environment
- Better heat tolerance for longer sessions
- Enhanced therapeutic benefits
- More efficient body warming
- Improved breathing comfort
Understanding Infrared in Saunas
Far infrared technology represents the most researched and beneficial form of infrared therapy. This technology works through a process called resonant absorption, where far infrared waves interact primarily with water molecules in your body. This interaction creates a pleasant, deep-penetrating heat that feels similar to the natural warmth of sunlight on your skin.
While there are three types of infrared light (near, mid, and far), far infrared has proven to be the most beneficial and safest for sauna therapy.
Here’s why:
Far Infrared (FIR):
- Optimal interaction with body tissues
- Safe and thoroughly researched
- Perfect heat penetration depth
- Comfortable and effective warming
- Proven therapeutic benefits
Near Infrared (NIR)
- Potential risk of eye damage from direct exposure
- Can cause skin damage with prolonged use
- Impossible to deliver safe, consistent therapeutic doses in a sauna setting
- No proven benefits specific to sauna use
- May require protective eyewear
- Studies showing benefits are only for specific, targeted, medical treatments
- See more about NIR Dangers
Mid Infrared (MIR)
- Lack of comprehensive research supporting sauna applications
- Inconsistent heating patterns
- No established safety protocols for prolonged exposure
- Limited therapeutic value compared to far infrared
- May cause uneven heating of body tissues
- No proven advantages over far infrared technology
It’s important to note that while some companies market “full spectrum” saunas (a term coined in 2009), the inclusion of near and mid infrared lacks scientific support for sauna applications. In fact, these shorter wavelengths may pose unnecessary risks without providing additional benefits.
Because “full spectrum” is a marketing term, there is no single definition or regulation specifying how much near infrared or mid infrared is produced in a full spectrum sauna and, in fact, it actually varies wildly between sauna companies. See more about “Full Spectrum” saunas.
How Far Infrared Saunas Work
Far infrared saunas utilize specialized heaters that emit the perfect spectrum of infrared light for therapeutic benefits. These heaters work by:
- Producing consistent far infrared waves
- Maintaining optimal emission temperatures
- Creating even heat distribution
- Possessing proper reflectivity to direct infrared waves
The key to their effectiveness lies in the emissivity of the heating elements – a property that determines how efficiently the infrared radiation is produced. High-quality far infrared saunas use materials specifically chosen for their superior emissivity properties as well as an ideal surface and material for reflectivity to ensure the infrared waves are directed specifically where you want them. See more about infrared sauna heaters.
The Critical Importance of Wood Quality in Infrared Saunas
The choice of wood in an infrared sauna is crucial for both safety and comfort, particularly for those with chemical sensitivities or allergies. High-quality, properly treated wood isn’t just about aesthetics – it’s a fundamental health consideration.
What Makes Wood Quality Important?
- Heated environments can cause poor-quality woods to release harmful compounds
- Chemical treatments and glues may off-gas when warmed
- Low-quality woods may contain naturally occurring toxins
- Repeated heating cycles can accelerate the release of volatile organic compounds (VOCs)
Potential Health Impacts of Poor Wood Quality
Low-quality or improperly treated woods can cause:
- Respiratory irritation
- Headaches
- Allergic reactions
- Eye irritation
- Skin sensitivity
- Aggravation of chemical sensitivities
- Worsening of asthma symptoms
Important Considerations for Sauna Wood
When selecting a sauna, the choice of wood material is crucial, particularly for individuals with chemical sensitivities, allergies, or respiratory concerns. The ideal sauna wood should be naturally resistant to decay and mold without requiring chemical treatments, and should emit minimal volatile organic compounds (VOCs). This natural approach ensures that when the wood heats up, it doesn’t release harmful substances that could trigger reactions in sensitive individuals. See here for more information on different sauna woods.
Make Sure it is Non-Toxic and High Quality
- No chemical treatments
- Zero formaldehyde-based glues
- Natural wood sealants only
- Certified low-VOC materials
- No toxic stains or finishes
- Cured and dried properly
