February 10, 2026·1h 7m

You can sleep eight hours, follow all the usual tips, and still feel foggy and sore. If recovery isn't improving, the problem usually is the environment you're ignoring at bedtime. In this episode of Habits & Hustle, I sit down with certified sleep coach Jack Dell'Accio to break down why "cooling" mattresses backfire, what actually drives REM and deep sleep, and how toxins and EMFs keep the nervous system stuck in survival mode. Jack Dell'Accio is a Certified Sleep Coach with over 20 years of experience studying restorative rest and sleep environments. He is the Founder and CEO of Essentia, a company focused on non toxic, organically made mattresses designed to support neurological and physical restoration.
