Our Story

CET is an independent, non-profit professional organization dedicated to education and research on the new environmental therapies.

We are scientists and clinicians who work in the fields of psychiatry, psychology, chronobiology, sleep research and medicine, and gather on this website the findings of world-wide research on ENVIRONMENTAL THERAPEUTICS to help individuals and clinicians.

These treatments cover many clinical syndromes and diagnoses, in particular mood and sleep disorders, shift-work problems, but also children’s development, the ageing process, healthy architecture, and the politics of daylight saving time.
