Our Mission

Circadian Sleep Disorders Network is an independent nonprofit organization dedicated to improving the lives of people with chronic circadian rhythm disorders.

We aim to increase awareness within the medical community and among the general public, to provide emotional support and practical ideas for people living with these disorders, to inform patients and health care providers about treatment options, to encourage research into circadian rhythms, and to advocate for accommodations in education and employment for people with circadian rhythm sleep disorders.


We are a 501(c)(3) organization based in the U.S., serving the global circadian sleep disorders community. We are a patient organization, entirely supported by member dues and contributions.

We are an all-volunteer organization. None of the board members or officers is being paid. We are using our funds for expenses, such as the cost of applying for tax exempt status, printing costs, web costs, etc.

We see this as an international endeavor. While initially most of our activity will occur in the U.S., the information on our web site is available world-wide, and our brochures will be useful to English-speakers everywhere. The research we encourage will be useful world wide. In the future we hope to sponsor affiliated groups in other countries.

Note that all our directors and officers are volunteers. We are not paid for our work.

Some History

Around 1996 Wendi Dunlap started an email list at for people with CSDs. The list has grown to over 600 members, primarily people with DSPS or N24 or their family members. Some people on the list felt we needed a more formal organization to promote awareness of CSDs, and to advocate for accommodations. Circadian Sleep Disorders Network is the result. We incorporated on August 18, 2011, and opened to membership on January 1, 2012.

We very much want to be representative of the CSD community, and we took care to involve the niteowl list in the initial discussions, including choice of the name for the organization. We also asked for volunteers to be consulted on subsequent decisions. Anyone who volunteered was added to an Advisory Panel, which was consulted on important issues during the startup phase. As a result, of course, progress was slower than if we had simply made decisions in isolation.

We've now incorporated, set up a web site, adopted bylaws, expanded the Board of Directors, elected officers, set up finances and accounting, defined membership, integrated dues payments with PayPal (you can write a check instead, if you prefer), applied for and received tax-exempt status, and filed tax returns. We have formed a Medical Advisory Board, expanded the web site, and formally affiliated with the Niteowl Email List. We are developing programs and strategy, and embarking on the goals in our mission. There's still a lot to do! Current activities are in the News section of our Home Page.

Privacy Policy

We take your privacy seriously. We understand that you may not want your membership in Circadian Sleep Disorders Network to be public information, and we take every precaution to keep your data private. We will never sell or give away our membership information. That promise is enshrined in our bylaws!

Our membership list is private, and only accessible by the few people with a need to know. Currently, that is the president, vice president, treasurer, and secretary, since they need to process your membership dues, email the election ballots, etc. The election ballots are processed by a third party (, so they do get your email address, but they promise not to use it other than for the conduct of the election. We use MailChimp to send the newsletters, so we don't trigger spam blockers, so they too receive the list of email addresses.

We are not requiring members to provide any more personal information than they are comfortable providing. However, if you do not give us a valid email address, we will not be able to contact you at all, so we do ask for that.

If you pay using PayPal, only PayPal gets your payment data (bank account or credit card). We never see this information. We can view the name and email address you provide to PayPal, and in some cases the street address as well, but we will not make use of this. You may also pay by check. We will not retain any bank data from the check.

We will retain your membership information for three years after your membership lapses, to allow us to send renewal reminders and perhaps some especially important news. After that, all information about you will be deleted.

Niteowl Email List

This is a free 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

Note that membership in Circadian Sleep Disorders Network and membership on this email list are completely separate.


Circadian Sleep Disorders Network is affiliated with this email list, and our volunteers assist the list administrator with some chores. CSD-N was formed by participants on this list, and many of our members post regularly. But we have no control over what appears or who can join, and list membership is completely separate from membership in CSD-N.


Once you've signed up for the list, you post by sending an email to Everyone on the mailing list receives that post as an email, and you receive everyone else's posts as emails. If you don't like to get separate emails, you can opt to receive in digest form, typically one email a day containing all the day's posts. You make that selection (after signing up) by logging in at


There are some rules:
The rules that the list software enforces are

One frequent problem is that people with more than one e-mail account try to send from an address that isn't registered as a member here. An infrequent problem is that a few e-mail providers aren't accepted at all so another e-mail account must be (acquired and) used. gmail generally works well.

An additional rule is PLEASE do not just reply to a message with a subject line containing "Niteowl Digest, Vol xxx, Issue xxx". That is obviously not informative and if you aren't careful you may include the whole list of messages in the Digest, making your message too large for the list.

Digest or not, it is a good idea to trim whatever you are replying to leaving just enough for people to know what you are replying to.

Of course, don't be snippy or insulting, and please take off-topic conversations off-list. And no advertising.


Once you've signed up for the list, you can also browse previous posts in the archive at

There is also a mirror of the archive on Yahoo at This is useful when the primary archives are not working, as sometimes happens. Login to your Yahoo account, or create one (free) - link is at the top right on that page. Then you have to Join the Yahoo copy of the list - this is separate from signing up for the list itself - there is a button on the Yahoo page to do this.
