Tossing and turning, racing thoughts of revision and exams... most of us know what it feels like to struggle with our sleep when we're preparing for a big challenge. And it can be tempting to sacrifice sleep when we're under time pressure, even though we know it's good for us. It's a real catch 22.

This week, we sit down with Professor Russell Foster from the University of Oxford. He's been studying sleep for decades, so together we dig into what's happening in our brains when we sleep, why it's so important for our health and wellbeing, and how we can prioritise our sleep to help us cope with stress.
