Ottofond - light therapy

relaxation through pure coloured light

Alongside air and water, light is an irreplaceable “basic need” for people and for nature. Coloured light is pure energy, pure nourishment for body, spirit, and soul. Coloured light therapy optimises your personal energy level. Energy from the colours conveys stimulating, harmonising and rejuvenating forces. Colours have an effect on nerves, glands, and organs whilst having a powerful effect on the psyche. The body is exposed to coloured light, and up to 80% of it is absorbed by the skin. The radiation penetrates up to 10 mm into the skin, triggering reactions in somatic cells that are forwarded to the brain.

The colour changer consists of an electronic control unit and two LED spotlights, each with three high-performance 3 watt LEDs in the primary colours red, green, yellow, white, and blue.
