Chromotherapy

It’s a form of therapy that uses color and light to treat certain mental and physical health conditions. We can trace this form of therapy back to the ancient Egyptians. They made use of sun-filled rooms with colored glasses for therapeutic purposes.

Chromotherapy uses wavelengths of color light to positively alter the biochemistry of the body to promote deep healing.

Chromotherapy used in conjunction with infrared sauna treatments becomes even more effective as the infrared spectrum of light, through its power to penetrate deeply into the soft tissues of the body, encourages the body to absorb the full spectrum of color emitted through chromotherapy instruments.
