In this episode of the Sleep Reimagined series, host Layla interviews sleep specialist Nyree Penn, MHSc., CAA, to explore how modern technology—smartphones, wearables, smart rings, glasses, and apps—affects sleep biology and behavior. Nyree explains that bedtime phone use exposes the eyes to blue light, which suppresses melatonin and disrupts the circadian rhythm, while the dopamine surge from scrolling creates a state of dopamine depletion that undermines the ability to relax. She introduces the concept of orthosomnia, the anxiety‑driven obsession with sleep scores generated by wearables, and warns that over‑reliance on data can increase stress rather than improve sleep. The conversation covers the physiological parameters tracked by wearables (REM/non‑REM, oxygen saturation, heart rate, apnea events) and their utility for identifying sleep‑disordered breathing, but stresses that subjective feeling remains the primary indicator. Practical recommendations include a screen curfew (30 minutes before bed), using “Do Not Disturb” and night‑mode settings, morning sunlight exposure, a bedside notepad for a brain‑dump, limiting notifications, and using calming audio tools (e.g., Calm, BrainTap). Nyree also describes ProSomnia’s personalized sleep therapy, which uses anesthesia‑guided deep‑REM sessions and neuroplasticity techniques to reset adenosine pressure and restore natural sleep architecture. The episode concludes with a call to listeners to step away from screens, trust bodily cues, and view sleep as lived experience rather than a tracked metric.
