Why do some people lie awake exhausted, yet unable to stop their thoughts racing?

New Australian research suggests chronic insomnia may not just be stress or bad habits — it could be linked to the brain’s internal clock failing to slow down at night. In this episode, we speak with Dr Chelsea Reynolds, clinical psychologist and sleep researcher, about findings from the University of South Australia showing that some insomnia sufferers remain in a “daytime thinking mode” when the brain should be winding down.

Around 10 per cent of Australians experience chronic insomnia, with rates even higher among older adults. The research suggests that in some people, the brain’s rhythm may be delayed by as much as six and a half hours — meaning their internal night does not begin when the clock says it should.

We explore what is happening in the brain during those restless hours, why switching off can feel impossible, and what treatments may help. From timed light exposure and structured daily routines to mindfulness and digital cognitive behavioural therapy programs, new approaches are offering practical solutions.

If you or someone you know struggles with sleep, this episode offers science-backed insights and real-world help. Learn more about ongoing insomnia research and free digital treatment trials at https://www.bedtimewindow.com/.
