White noise might be doing more than helping your baby sleep—it could be shaping how their brain develops, regulates stress, and learns language. Registered nurse and master neuroplastician Beverly Hansen makes a bold case for why parents should rethink the machines so many families use every night.

Beverly shares the deeply personal story that led her to write White Noise Dark Impact: Are We Damaging Children’s Brains? and explains how a painful family estrangement became the catalyst for a global mission. What started as one grandmother’s concern has turned into a worldwide conversation about baby brains, hearing loss, cortisol, REM sleep, and the hidden cost of constant noise.

In this episode, you’ll discover:

Why eight to 10 hours of nightly white noise may be more disruptive than parents realize

How noise can act as a stressor, elevating cortisol and affecting the brain’s threat-detection system

Why infants and toddlers need natural sound variety for language development and emotional regulation

What research says about pink noise, REM sleep, and memory consolidation

Whether music like Mozart may support neuroplasticity instead of suppressing it

Sherry and Beverly also connect the neuroscience to everyday life—from earbuds and EMFs to screen time, sleep habits, and the small routines that help busy moms protect their own well-being.

Beverly opens up about faith, purpose, and healing after loss, sharing how adversity pushed her into a stronger spiritual life and a bigger calling. She also offers free resources on hearing, language acquisition, and anxiety.
