What Is Infrared?
Infrared is a naturally occurring form of light energy that comes from the sun — though it’s invisible to the naked eye. While sunlight includes the full color spectrum along with ultraviolet (UV) and infrared rays, it's the far infrared wavelengths that matter most for your health. Unlike UV rays that can damage skin, far infrared (FIR) offers therapeutic benefits, including deep heat penetration, detoxification, and cellular activation.
In fact, our bodies naturally emit far infrared heat — it’s the same warmth you feel when you rub your hands together. When used in sauna therapy, this specific wavelength penetrates deep beneath the skin, helping to mobilize toxins, stimulate metabolism, and promote overall wellness.
What Is Far Infrared?
Far infrared heat goes deeper than conventional heat — reaching up to 2 inches below the skin’s surface. This deeply warming energy activates sweat glands and encourages your body to eliminate built-up toxins through sweat, often called the “third kidney” for its powerful detox capabilities.
Research has shown that FIR wavelengths in the range of 9.3 to 9.4 microns resonate with the body’s natural frequency, causing water molecules in the tissues to vibrate. This vibration helps break apart toxic clusters, releasing them for elimination. The result? Clearer skin, improved circulation, reduced inflammation, and a more efficient metabolic system.
What Is Full-Spectrum Infrared?
Full-spectrum infrared saunas include all three infrared wavelengths: near, mid, and far infrared — each offering unique wellness benefits:
-
Near Infrared (NIR): The shortest wavelength. Penetrates the skin’s surface to promote skin renewal, wound healing, and collagen production.
-
Mid Infrared (MIR): Reaches soft tissues and muscles to improve circulation, reduce inflammation, and accelerate recovery.
-
Far Infrared (FIR): The deepest wavelength. Reaches fat cells, stimulates detoxification, and supports weight loss by boosting core temperature and metabolism.
By combining all three, a full-spectrum sauna delivers a more complete therapy experience, reaching multiple systems of the body at once.
Why Infrared Is Superior to Traditional Saunas
While traditional saunas rely on extremely hot air (180°F–220°F) to warm the body through conduction and convection, infrared saunas use direct radiant heat that mirrors the body’s natural heat signature. This allows infrared saunas to operate at lower, more comfortable temperatures (100°F–165°F), while still delivering a deeper, more effective sweat.
Other key differences:
-
Faster warm-up time: Ready to use in minutes.
-
Lower energy costs: More efficient than traditional saunas.
-
Longer, more comfortable sessions: Stay in longer and recover faster.
With Sun Home Saunas, you get high-performance, ultra-low EMF infrared heaters that convert up to 93% of their energy into heat your body can absorb. You’ll feel a gentle warmth from the inside out — not the suffocating blast of hot air.
Experience Infrared in Everyday Life
Ever felt warmth radiating from your hands when you hold them close together? That’s your body emitting far infrared heat. We’re constantly surrounded by infrared energy — it’s how the sun heats the Earth and how warmth transfers between living things.
Even ancient Korean floor-heating systems (Ondol) were rooted in this principle, using stone and earth to radiate infrared warmth. Today, infrared therapy is used worldwide in medical, wellness, and recovery settings — and now, it’s available in your home with Sun Home.
