We’re stuck in a loop of digital distraction, chronic stress, and hormone imbalances — and it’s quietly destroying our well-being.
From sleepless nights to burnout to hormone chaos, modern life is out of sync with what our bodies need. This book reveals how cortisol — the misunderstood Master Hormone — is at the center of it all.
I’m not a doctor, and I’m not here to sell you hacks or hype. I’m a founder, a husband, a dad, and someone who’s spent the last decade deep in the science of stress, sleep, and hormones. Not from the sidelines, but in the trenches. Building products, running clinical trials, listening to real people, and living it all myself.
Stress Nation isn’t another wellness manifesto for the privileged few. It’s a wake-up call for the rest of us, the ones juggling work, relationships, health, and purpose while the world spins faster and expectations climb higher.
This book is practical. It’s honest. It’s built on science, but written for humans. No ego, no gatekeeping, no overpriced gadgets required.
If you’ve ever felt wired but tired, overwhelmed, burnt out, or just off… this is for you. Whether you’re climbing the corporate ladder, raising kids, rebuilding your health, or just trying to make sense of it all, Stress Nation will help you get back in control. One small shift at a time.
Because you deserve to feel good again.
And you shouldn’t have to burn out to wake up.
