Are you aged 18–45 and healthy?

Hello world

Join our research study on light exposure and the body clock.

This study is about how typical artificial indoor lighting versus a simulation of a natural sunset influences the timing of the human body clock. The body clock controls 24-hour patterns of physiology such as sleep and hormone release. This work will have important implications for determining how implementation of new lighting technology can be used to promote sleep.

We are looking for healthy men and women, ages 18–45, to participate in a study lasting approximately 15 days, consisting of wearing an activity tracking watch at home and two laboratory visits of about seven hours each at the CU Boulder Sleep and Chronobiology Laboratory.

Compensation up to $200.
