What is Colourtherapy? How does it work? How can it make you feel better?
This page explains what Colourtherapy is and provides links to the leading scientific research papers. It's worth a read, as it can change your daily life.

Colour (Chromo) Therapy is a method of treatment that uses the visible spectrum (colours) of electromagnetic radiation to cure dis-eases. It’s a centuries old concept used successfully over the years. From ancient Egypt to the contemporary treatment of seasonal affective disorder (SAD), a form of depression.

Both light and colours are composed of electromagnetic energy. Each colour represents a different intensity, or pulse, of energy. These energy waves are being taken in through the body and especially the eyes.

Through your eyes, these energy waves connect directly with your brain and your blood. Out of all muscles in our body the eye muscles move the most (100,000 per day) and consequently our entire blood passes through the eyes approx. every 40 minutes. As the thinnest membrane between light and our blood, the eye allows light frequency to enter the body and help program our cells.

  • Can help with anxiety and depression.
  • Gives greater definition to visual experiences - great for the beach, skiing and walking.
