About this listen
Struggling with stress, anxiety, or low mood? Sleep might be the missing piece. In this episode, I break down a meta-analysis of more than 8,600 people that found improving sleep quality can directly boost mental health—reducing depression, anxiety, stress, rumination, and even psychosis symptoms. We’ll look at how different sleep interventions work, why the benefits are strongest with consistent follow-up, and what this means for mental wellbeing. If you’ve ever wondered whether better sleep could truly change your mind, this episode is for you.
