Fred Hutch is recruiting adults to participate in a study to learn more about individual light exposure and timing of sleep. We hope to use the information that we collect to develop larger studies to understand the health effects of light exposure.
Below you will find the eligibility criteria and survey. If you fill out the survey and are eligible, you will have the option of being contacted by the study staff to see if you would like to enroll in The Light Study.
Help us learn about light exposure and sleep timing.
