Summary

This study tested a 24-week sleep program delivered partly through WhatsApp for people with heart failure and poor sleep. The program included education, daily tips, and smartwatch sleep tracking. Researchers measured sleep quality, sleep habits, and quality of life in 28 participants.

What this could mean

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

Active substance
WhatsApp-based sleep health program
What this could lead to
If it works, this could offer a simple, low-cost way to help heart failure patients sleep better and feel better.
What could go wrong
This is a small, early study with only 28 participants, so results may not apply to everyone. The intervention relies on behavior change, which can be hard to maintain.
