Experimental: Online Sleep Education
The sleep intervention is a multi-component online intervention consisting of sleep information and sleep hygiene education, along with behavioural and cognitive components.
|
|
|
Kein Eingriff: Usual CV care
Specialist nurses will administer the CV risk factor education intervention to participants in small groups over one hour.
