What if every bad decision you’ve made started with your sleep?

Many of us see sleep as rest, but in reality it’s the foundation for everything we do in life.

Today I’m joined for the second time by Matthew Walker, a neuroscientist who has spent years studying the impact of sleep on the brain and the body.

He sees sleep as the social ‘glue’ that keeps us together.

This time, Matthew brought me through his ‘QQRT’ framework - a simple way for all of us to measure our sleep health.

We cover:

- Why does the last hour of sleep matter more than the first? - Are supplements like melatonin and magnesium even helping your sleep? - What’s the single most powerful thing you can do to sleep better? - Is using your phone before bed harming your sleep quality? - What does poor sleep actually do to your brain long term?

and so much more…

There is constantly so much new science on sleep and the advice is becoming a lot more practical.

I’ve come to believe that sleep sits upstream of almost everything we struggle with - our focus, our mood, our relationships, and even our health.
