Host Dave Asprey sits down with Andy Mant, Co-Founder and CEO of BON CHARGE, and Katie Mant, Co-Founder and Chief Visionary Officer, to unpack how modern light, WiFi, and nonstop screen exposure are quietly shaping your sleep, hormones, and energy. After facing their own struggles with fatigue and poor sleep, they built BON CHARGE around science-backed biohacking tools designed to improve sleep, recovery, and overall wellness. 

They start with blue light at night and content overload, why light acts as biological information, and how simple changes like wearing blue light blocking glasses before bed can shift your circadian rhythm. The conversation moves into EMFs, native versus non-native frequencies, and what happened when they lived in an apartment flooded with WiFi and 5G. Dave shares his DEXA scan showing about 15% lower bone density where he used to carry his phone and explains why he now limits direct exposure. 

You’ll also get a practical breakdown of red light therapy and PEMF, including the difference between visible red and near-infrared light, how dosing affects results, and how mat-based PEMF is used to support relaxation and recovery. This episode stays grounded: you do not have to give up technology, you just have to learn how to hack your environment so it works for your biology instead of against it. 

You’ll Learn: 

• Why blue light at night can disrupt sleep and circadian rhythm 

• How light acts as information that shapes hormones and metabolism 

• Practical EMF reduction strategies you can test immediately
