Summary

This trial tests if flashes of light can help teens with DSPD wake up in the morning, go to bed early, and reduce fatigue & depression.

Who is the study for?
This trial is for high school students who have trouble waking up early and falling asleep at night, often feeling depressed or restless during the day. It's specifically designed to help those with Delayed Sleep Phase Disorder (DSPD).
What is being tested?
The study is testing if brief light flashes during sleep can help treat DSPD. The goal is to see if this method can adjust the participants' sleep patterns to a more conventional timing.
What are the potential side effects?
Since the intervention involves light flashes, potential side effects may include temporary discomfort due to being woken up or disturbed during sleep by the flashes.
