The Sleep and Chronobiology Laboratory is looking for people with delayed sleep-wake phase disorder or people with late bedtimes, or healthy people with typical bedtimes.

The purpose of this study is to improve our understanding of mechanisms of delayed sleep-wake phase disorder (DSWPD).  We are testing patients with DSWPD as well as healthy people without DSWPD. The study is 6.5 weeks long with six in-person visits at CU Boulder.

You may be eligible for this study if you:

• Are ages 16–30
• Have a diagnosis of delayed-sleep wake phase disorder or have late bedtime after 1 a.m., an inability to fall asleep and difficulty awakening when required for school/work
• Or are healthy with typical bedtimes and no sleep concerns

Study activities include:

• Health screening
• Monitor on separate occasions your sleep, mood, eating times for one or two weeks and blood sugar levels while living at home
• Live in the sleep laboratory on two separate occasions for 48–66 hours (approximately 4.75 days in total)
• Blood and saliva sampling and reaction time, mood, and ability to think testing

Compensation is up to $1,725. Get study details and apply.
