Welcome to the Center for Environmental Therapeutics!

Although our name is a mouthful, we hope it will not keep you from enjoying our site, learning useful ways to improve your mood, sleep, and energy level, and perhaps finding out about the science behind these practical applications. And if you think of a better name to cover scientifically-developed therapies that focus on natural elements, such as light, please let us know at info@cet.org.

You can read about our mission, and experts, at About, and catch a glimpse of our volunteers at Join Us!

Here, you can read the answers our experts have given to people like you who had questions about depression, light therapy, seasonal affective disorder, and other topics. If you have a question that has not been asked, you can submit it.

You can also read our version of FAQs: QWWPWAs, or Questions We Wish People Would Ask.

Finally, if you are a clinician, you can join our Clinicians’ Forum. There you can confidentially join colleagues to explore, or create, solutions for the challenges you face in helping current patients and clients with light therapy, wake therapy, and other treatments.
