Turn Off Your WiFi Tonight and See What Happens to Your Sleep : 1414

The Human Upgrade with Andy Mant & Katie Mant 2026-02-12

Summary

Dave Asprey sits down with Andy and Katie Mant, founders of BON CHARGE, to explore how blue light, WiFi, 5G, and screen exposure affect sleep, hormones, bone density, and cellular energy. The conversation covers how light acts as biological information that influences circadian rhythm, why nighttime blue light disrupts sleep quality, and the difference between native and non-native EMFs. Dave shares his own DEXA scan data showing roughly 15% lower bone density where he habitually carried his phone.

The discussion moves into practical biohacking tools including red light therapy, near-infrared light for deeper tissue and mitochondrial ATP production, and PEMF mats for nervous system regulation and recovery. They distinguish between visible red light for skin-level benefits and near-infrared wavelengths for deeper penetration, and explain why dosing and frequency matter with light therapy. The episode emphasizes that you don't need to abandon technology -- you just need to hack your environment so it supports your biology rather than working against it.

Key Points

  • Blue light exposure at night disrupts circadian rhythm and suppresses melatonin, directly impairing sleep quality
  • Light acts as biological information that influences hormones, mood, metabolism, and skin health
  • Switching your phone to airplane mode and unplugging WiFi at night are simple EMF reduction strategies that can improve sleep
  • Native EMFs (from the earth, sun) are beneficial, while non-native EMFs (WiFi, 5G, cell signals) may interfere with cellular function
  • Dave's DEXA scan showed about 15% lower bone density in the area where he carried his phone in his pocket
  • Red light (visible) targets skin-level benefits, while near-infrared light penetrates deeper tissues and supports mitochondrial ATP production
  • PEMF therapy uses pulsed electromagnetic fields to help shift brainwave states toward delta for deeper recovery and sleep

Key Moments

Red light therapy is booming: red, near-infrared, and far-infrared each offer different benefits

Red light therapy is one of the fastest-growing wellness categories globally. Red, near-infrared, and far-infrared wavelengths each provide distinct benefits for recovery, sleep, and cellular energy. The shift is from beauty tool to serious health intervention.

"I've been into red light therapy ever since because I just felt such a shift. And I was fine in two weeks with what would have been a year of suffering."
