A common barrier to sleep is having a hard time switching off from thoughts. The Centre for Clinical Interventions (CCI) in Australia provides a range of free, evidence-based self-help resources on sleep and worry that utilize cognitive behavioral therapy (CBT) techniques. Resources are also available for a range of other mental health and emotional concerns on the CCI website.
Sleep and mental health have a bidirectional relationship. This means a negative (or positive) change in mental health will usually impact sleep in the same way. The resources on the CCI website can be used to work through problems like worry and anxiety that often contribute to sleep difficulties.
