Summary

This study tested whether a 10-minute daily mindfulness session via a smartphone app could improve sleep and lower stress in healthy adults. 81 participants wore an Ōura Ring to track sleep and heart rate, and were randomly assigned to either the mindfulness program or a waitlist. The goal was to see if a simple, app-based routine could make a real difference in sleep quality and relaxation.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
app-based mindfulness program (Headspace via Ōura app)
What this could lead to
If it works, this could point toward a simple, low-cost way to improve sleep and reduce stress in healthy people using a smartphone app.
What could go wrong
This is a small, completed trial in healthy adults with low stress, so results may not apply to people with sleep disorders or high stress. The intervention is very short (10 days), and benefits may not last.
