In this episode, I am offering something that has genuinely changed the way I think about my body — the circadian rhythm.
I share what this 24-hour internal clock actually is, why researchers say it runs everything from your metabolism and hormones to your sleep and immunity, and how understanding it gave me a whole new perspective on the ongoing conversation around meal timing and breakfast.
I walk through a few practical strategies rooted in circadian science that you can simply be aware of and explore in your own life.
And yes — I am raising my hand on the late-night phone habit, because that quote of the week? It hit home for me too. Come learn something new about the incredible, intelligent design of your own body.
QUOTE OF THE WEEK
“Studies have shown that every hour you’re still on your mobile phone, tablet, laptop, or watching TV at night, melatonin is suppressed by 30 minutes.”
— Dr. Satchin Panda, The Circadian Code
