The Science of Breathing: James Nestor & Anders Olsson
from Irina Lee On Energy | Mindset, Habits & Emotional Mastery · host Irina Lee
In this episode, I sit down with James Nestor, author of the bestselling book Breath, and Anders Olsson, founder of Conscious Breathing.We explore what really happens inside the body when we change the way we breathe.We talk about:• The Stanford experiment where 10 days of mouth breathing changed sleep, energy, and focus• Why carbon dioxide is not the enemy• How nasal breathing affects stress, digestion, and athletic performance• The link between breathing and sleep disorders in children• Why snoring is a warning sign• How something as simple as prolonging your exhale can shift your nervous systemThis is not about trends.It’s about physiology.It’s about habits.And it’s about reclaiming something we do 20,000 times a day — often without awareness.I also share parts of my own journey into breathing, which began during the pandemic when anxiety showed up in my body — and I realized my breath was the fastest way back to calm.If you’ve ever struggled with stress, poor sleep, low energy, or simply want to understand your body better — this conversation will open your eyes.Before you finish listening, try this:Close your mouth.Let your tongue rest in the roof of your mouth.And make your exhale slightly longer than your inhale.Let the journey inwards begin. 🫁
