What is Infrared Light

Infrared is light, for life.

Nature gives us infrared light. You can’t see it with your eyes, but you know it. It’s that good feeling you get the moment the sun comes out on a cloudy day. It’s the warmth you love to soak up at the beach or next to a fire.

Infrared is the healthy, healing rays that come from the sun, the ones that feel like a hug. It also helps plants bloom. The right amount helps stems grow fast and strong. Everything in nature needs it to live. And we don’t get enough of it in our modern world.

Watch this video to “see” infrared in action.

Animation helps make what’s invisible visible, so we created this 2-minute video to help you better understand what infrared is and how our bodies interact with it. Our bodies are like solar panels designed to absorb infrared light, which activates our body’s cells to produce the energy that boosts health and slows aging. Watch to learn more!

Science-Backed

We led the infrared sauna industry by being the first to combine light science with published studies of how infrared affects the body; other companies followed us. We have the patent on our heaters and NASA-inspired LED panels which means only ours emit precise wavelength combinations.

Proven Technology

Studies are costly and complex. Not many sauna companies have had clinical studies done on their saunas. Sunlighten has three studies using our technology that have proven ours temporarily lower BP, reduce waist size and increase flexibility.

Sunlighten’s Specific Wavelengths

Like dials on a radio station, there are many frequencies of infrared and its next-door neighbour, visible red light (infrared means “below red”). With a commitment to ongoing in-depth research, study and innovation, we’ve dialled in our wavelengths to specific infrared and red light wavelengths. We focused on the science and studies that show these are best absorbed by the body and most effective for optimal wellbeing, vitality and longevity. Here’s an overview of each of Sunlighten’s wavelengths, and what they activate in your body:

Far Infrared

- Foundational infrared wavelength (9.4 microns)

- Only FIR heater clinically shown to raise core body temp 3°

- Absorbed by water cells

- Activates sweat glands, deep detoxifying sweat

- Energizes and revitalizes, not draining heat

- 95-99% emissivity = maximum absorption/bioavailable wavelengths
