Episode notes
Personal Drive From Father's Sensitivities
- Jack's father became sensitized to chemicals after cancer, prompting Jack to research safer sleep materials.
- That led him to reformulate latex foam and launch Essentia to address toxins and performance.
Environment Can Sabotage Sleep Quality
- Sleep environment stimuli can keep your nervous system activated even with eight hours of sleep.
- Eliminating toxins, heat, EMFs and allergens lets you spend more time in deep sleep and REM.
Temperature Changes Break Deep Sleep
- Thermoregulation during the entire sleep period—not just at onset—determines how much deep sleep and REM you get.
- Even brief temperature rises push you into lighter sleep and cause awakenings.
