What matters in a red light sauna?
Wavelengths, light placement and the amount of light all matter in a red light sauna. Sunlighten combines red and near-infrared light with the infrared sauna experience.
Wavelength
Visible red and invisible near-infrared light are complementary wavelengths used in photobiomodulation.
Placement and coverage
The distance from the light source and the placement of the panels affect how much light reaches your body.
Amount of light
The aim is an appropriate dose. Wavelength and session duration both matter.
Infrared heat
Light and heat work together as part of the sauna experience.

PHOTOBIOMODULATION · PBM
Begin with light
Photobiomodulation (PBM) uses light at selected wavelengths. The term describes the relationship between light and biological processes.

Photo – light
Light is the starting point of photobiomodulation.

Bio – biology
We look at the relationship between light and the body.

Modulation – influence
Wavelength and the appropriate amount of light both matter.

WAVELENGTH
Red and near-infrared light
Red light is visible, while near-infrared light cannot be seen with the naked eye. Their different properties make them complementary.
Amplify RED integrates the light into the sauna walls. Panel placement and proximity to your body shape the light experience.
How light reaches your body matters
Distance from the source and panel placement affect how much light reaches your body. Sunlighten integrates red and near-infrared light sources into the sauna walls.

Visible red light
Visible red light lets you see where the light sources are.

Proximity
The distance between the light source and your body is part of the light experience.

Surrounding placement
Integrated panels deliver light from several positions within the sauna.
THE APPROPRIATE AMOUNT
Aim for the appropriate amount of light
Light effects cannot simply be increased without limit: wavelength, dose and session duration all matter. Always use your sauna in accordance with its user guide.

LIGHT AND HEAT
A red light sauna is still a sauna
Infrared heat is part of the experience alongside PBM. Amplify RED combines its integrated light panels with SoloCarbon® far-infrared and full-spectrum heating elements.
The light and heat technologies work together as one sauna system.
Light science in Sunlighten design
Red and near-infrared light, SoloCarbon® infrared heat and full-spectrum heating elements come together in the sauna experience. Cabin size, placement and control options also matter when choosing a model.
