Purpose. The purpose of this study is to test sleep and wake-promoting countermeasures to evaluate their effectiveness in helping individuals fall asleep quickly, maintain sleep during a nap, and maintain alertness during waking. Protocol Overview. The proposed study involves two laboratory visits separated by at least one week. Participants are required to complete all procedures in the companion screening and at-home protocol in order to qualify for this laboratory protocol. The at-home protocol involves keeping a regular schedule for 2-3 weeks. Participants will need to maintain a regular schedule with at least 8.5 hours in bed for at least one week prior to the first laboratory visit. They will then continue the at-home protocol, maintaining at least 8.5 hours in bed each night for at least a week before completing the second laboratory visit. There are two interventions that participants will experience during the study, sleep promoting (pink noise) and wake promoting (blue enriched lighting plus a nap). These will be delivered separately and together depending on randomization. Participants will first be randomized to one of three conditions sleep promoting + wake placebo, sleep placebo + wake promoting, or sleep promoting + wake promoting. All participants will complete a sleep placebo + wake placebo condition. The order of the full placebo condition versus the intervention (i.e., lab visit 1 vs. lab visit 2) will be randomized after the condition randomization occurs. Each participant will complete one of the interventions and one placebo for a total of two visits.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
