ClinConnect Summary

This clinical trial is studying a simple program designed to help young adults keep a regular sleep schedule during the Christmas holiday. The program includes keeping a special sleep diary, learning 10 easy tips to maintain consistent sleep times, and receiving information about good sleep habits. Researchers want to see if this brief intervention can help young people avoid big changes in their sleep patterns during the festive break.

To take part, you need to be between 18 and 24 years old, live in Hong Kong during the study, and not have a fixed schedule like work or school that forces you to sleep or wake up at set times during the holidays. People who have recently traveled across time zones, have certain sleep disorders, take medications affecting sleep, or have serious health conditions would not be eligible. If you join, you’ll be asked to track your sleep and try out the suggested strategies over the holiday period. This study hasn’t started recruiting participants yet, but it aims to find easy ways to help young adults maintain healthy sleep habits during times when routines often change.
