We breathe over 20,000 times a day. Those breaths do far more than just keep us alive. They shape your sleep, your focus, your energy, even your blood pressure and long-term risk of disease.

That’s over 20,000 opportunities to support your health, every single day.

The challenge is that modern life makes it harder to breathe well. We sit hunched over laptops, we’re constantly switched on, we chew softer foods, and many of us mouth-breathe, especially at night.
My guest today is on a mission to improve our health through our breath.

James Nestor is an award-winning science journalist and author of the bestseller “Breath”. He’s travelled the world to understand how our breathing has changed, and most importantly, what simple, practical steps we can take to improve it.

This episode genuinely shifted things for my team and me. I hope it inspires you to make a few small changes too. And if you know a committed mouth breather, send it their way.

We cover:
The risks of mouth breathing and James’ 10-day experiment
Why nasal breathing makes such a difference
Tips for a blocked nose or deviated septum
How to train your diaphragm for easier breathing
Why softer modern diets can affect your airways
