Sleep Hygiene Education in Individuals With Cardiovascular Disease: Effects on Sleep Quality and Disease Management

The Effect of Sleep Hygiene Education on Disease Management and Sleep Quality in Individuals With Cardiovascular Diseases: A Randomized Controlled Clinical Trial Protocol

This clinical trial aims to find out if sleep hygiene education helps people with cardiovascular disease manage their illness better and improve their sleep quality.

Participants will be randomly assigned to two groups. One group will receive sleep hygiene education through a 30-minute presentation and twice-daily reminder messages for four weeks. The other group will receive usual care without education.

Before and after the four-week period, all participants will complete questionnaires about their sleep habits, sleep quality, and disease management.

The study hopes to show that sleep hygiene education can improve participants' sleep and help them manage their disease symptoms better, leading to a better quality of life.

The trial will take place at Near East University Hospital's Cardiology Department from June to December 2025.
