Summary

This study explores whether a smartwatch app with personalized reminders can help people with insomnia better track their emotions, diet, exercise, and sleep. Sixty participants will wear a smartwatch and use an app for two weeks, with some receiving reminders timed to their daily routines. The goal is to see if this approach improves self-awareness and sleep management, and to gather insights for future digital insomnia treatments.

What this could lead to
If successful, this could lead to better digital tools for insomnia self-management, helping people understand how their daily habits affect sleep.
What could go wrong
This is a small, early-stage study (60 participants) focused on feasibility, not a treatment. It may not show clear benefits or apply to everyone with insomnia.
