Study on sleep loss

CU Boulder is seeking participants for a research study investigating how sleep loss affects decision-making and your body’s ability to digest and process the foods you eat. 

Participants must be healthy adults, ages 18–35, who normally sleep less than 6.5 hours per night during the school/workweek. Participants will complete six laboratory visits at the CU Boulder Sleep and Chronobiology Laboratory and six weeks of at-home sleep monitoring. Four of the visits will last between 0.5-2.5 hours and two of the visits will last about one day.

Compensation up to $750. Get study details.

For questions email the Sleep and Chronobiology Laboratory at and ask about the RADS study.

Sleep study study on light exposure, the body clock

Are you ages 18–45 and healthy?

This study is about how artificial indoor lighting influences the timing of the human body clock compared to an indoor simulation of a natural sunset. This work will have important implications for determining how new lighting technology can be used to promote sleep.

Looking for participation in a study lasting 15 days consisting of wearing an activity tracking watch at home and two laboratory visits of about seven hours each at the Sleep and Chronobiology Laboratory. Compensation up to $200.

For study details, email and ask about the Simulated Sunset study.

Study on sleep, performance and gut health

The purpose of this this Sleep and Chronobiology Laboratory study is to evaluate how sleep loss affects your ability to think and how it changes the helpful bacteria living in your gut. They are also testing how a prebiotic diet alters how you and the bacteria living in your gut respond to sleep loss and being awake at night. This research will help to create treatments and strategies for people working long hours under stressful conditions at night.

You may be eligible for this study if you are a healthy male or female ages 18–35.

Study visits include:

  • Consent appointment at the Sleep Laboratory
  • Medical screening appointment at Boulder’s CTRC
  • An actiwatch appointment at the Sleep Laboratory
  • Two application appointments of continuous glucose monitoring (CGM) sensors
  • Two out-patient food pickups in Aurora
  • Two laboratory visits spanning 3.7 days each (17 days in between visits)

Main procedures involved:

  • Consumption of prebiotic and placebo supplement
  • Sleep loss
  • Blood draws
  • Computer testing
  • Biological specimen sampling

Compensation is up to $2,451. For study details, questions or concerns, email and ask about the Navy study.

For kids

Study on cognition, emotions, resilience; ages 15–19

The Research on Affective Disorders and Development (RADD) Laboratory is interested in understanding how certain cognitive abilities, such as being able to pay attention or learn actions that help you achieve goals, may help teenagers to cope with stress and stay healthy.

This is a two-year study. Over the course of the study, you will have two study visits at their laboratory in Boulder, each lasting about five hours. During these visits you will be interviewed about your life experiences; you will complete some computer games that involve paying attention and learning; you will have a neuroimaging scan while you either rest quietly or play computer games; and you will answer a set of surveys on a computer.

Also as part of the study, you will complete a set of online surveys and a brief telephone interview once every six months (five times total during the two-year study participation). At the end of the study, you will have a final telephone interview, lasting about two hours.

You can earn up to $750 for your time and effort completing the study.

To learn more, you or your parent/legal guardian (if you are age 17 or younger) can contact the lab directly at 303-735-8306 or email You can also take the quick and easy online eligibility screen to see if you/your child is eligible to participate in this study.
