Like what you see? We need members! - the more people we have, the more impact we have when we try to raise awareness of circadian disorders with other organizations, the press, the medical community, and the public. Together we have a voice! Join now!

Our Brochure

We created a simple brochure to introduce DSPS and Non-24 to people experiencing symptoms of these disorders, and to their families. We encourage distributing this to anyone who may be interested. Print on lightly colored paper for a brighter look!

Brochure - web display     Print on US letter size paper, PDF
Print on A4 size paper, PDF

The web display version shows the brochure panels in easy-to-read order. The print versions are meant to be printed out on both sides of a sheet of paper, then folded in thirds, creating a brochure. (In the print version, the panels will appear out of order on-screen.)

Q&A Documents

We have posted documents describing DSPS and Non-24, in an easy to read Question-and-Answer format. These are designed to give to family members, friends, employers, and school personnel, to help them understand these disorders. Feel free to print and distribute these. There are two different (but similar) versions, one for DSPS and the other for Non-24:

DSPS Q&A - web     printer     booklet*
Non-24 Q&A - web     printer booklet*

The web formats display nicely in your browser. The printer versions are formatted by your browser for printing a multi-page document. The booklet forms are pre-formatted PDF files that you can print on two sides of a single sheet of paper, which then folds in half into a booklet.
* When printing the booklet, be sure to flip on the short edge (select this option if you have a double-sided printer).

Basic Fact Sheet

We've put together a short Fact Sheet as a quick way of introducing circadian sleep disorders to people who don't know about them. It's one side of one sheet of paper, so it's easy to print out. It's shorter and less dense than our brochure or our Q&A booklets, so it's a quick and easy read, just the basics.

Niteowl Email List

This is a mailing list support group for people with DSPS and Non-24 to share their experiences. It's a good place for people just discovering these disorders to hear how others deal with them, as well as for long-time participants to get support and to provide support to others. There are often discussions of evolving treatment, useful to all. For further information, and to sign up, go to

Sample Letters

Several members have contributed letters which they or their doctors have written in support of accommodation for CSDs. We include them here in case they can be of use to others. Names have been changed or removed. They are provided as guidance, but will generally have to be rewritten to suit your individual circumstances.
