This study is testing ways to help people sleep better and stay alert. It's looking at two interventions: "pink noise" delivered through headphones to promote sleep during the day, and "blue-enriched light plus a nap" to help with alertness at night. The study aims to see if these methods can help you fall asleep faster, sleep longer, and stay more awake when needed. You might be able to join if you are a healthy individual between 18 and 60 years old, not pregnant or breastfeeding, and do not have a sleep disorder or other chronic conditions that affect sleep. Success will be measured by how sleepy you feel (Karolinska Sleepiness Scale), your alertness (Psychomotor Vigilance Task), and brain activity during sleep (Electroencephalography). The current status of this study is unclear, and it plans to enroll 24 participants.

Study design

This is an interventional study with 24 planned participants. It is designed to compare different sleep and wake-promoting interventions.

What's involved

You would have two laboratory visits, separated by at least one week. Before these visits, you'll need to follow a regular sleep schedule for 2-3 weeks at home.

Compensation

Not stated in the trial record.

Follow-up

Your sleepiness will be measured for up to 120 minutes, alertness for up to 560 minutes, and brain activity for up to 48 hours.
