EP 1376
1376. Turn Off Your WiFi Tonight and See What Happens to Your Sleep
In this episode of The Human Upgrade, Host Dave Asprey sits down with Andy and Katie Mant, founders of BON CHARGE, for a practical deep dive into how blue light, WiFi, 5G, and nonstop screen exposure affect sleep, hormones, bone density, and cellular energy. They explore how light acts as biological information, why nighttime blue light disrupts circadian rhythm, what native versus non-native EMFs mean, and how simple habits like unplugging WiFi or using airplane mode can reduce exposure. The conversation also breaks down red light versus near-infrared therapy for mitochondrial support and recovery, PEMF for nervous system regulation, and how to use modern technology consciously as a biohacking tool rather than letting it quietly undermine your health.

Your phone, your lighting, and your WiFi can mess with your sleep and energy more than your diet, and this episode shows you the simplest fixes that actually move the needle.

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
- The difference between native and non-native EMFs
- Red light vs near-infrared light and how each is used
- Why dosing matters with red light therapy
- What Dave noticed on his DEXA scan after years of carrying a phone
- How PEMF mats aim to support relaxation and recovery

“But if you block all of it, you’re probably better off to have at least peace.”
Andy Mant
0:00 — Introduction
Dave opens with a provocative question about the most damaging part of modern technology and sets up a debate around awareness versus fear.
1:23 — Blue Light and Content Consumption
Andy argues that blue light at night and nonstop content consumption are major disruptors of sleep, circadian rhythm, and overall health.
2:31 — Light’s Impact on Health
They break down how light acts as biological information, influencing hormones, mood, skin, and metabolic function.
4:18 — EMF Awareness and Mitigation
The conversation shifts to EMFs, why awareness matters, and simple mitigation habits like airplane mode and unplugging WiFi at night.
9:16 — Living in EMF Hotspots
Andy and Katie describe living in an apartment flooded with WiFi and 5G signals and how a building biologist labeled their bedroom a “microwave.”
13:43 — Native vs Non-Native EMFs
They clarify the difference between beneficial natural electromagnetic fields and man-made non-native EMFs.
15:23 — PEMF Therapy Benefits
Katie explains how pulsed electromagnetic field therapy aims to help the body shift into calmer brainwave states like delta for recovery and sleep.
17:02 — EMF Protection Products
They outline BON CHARGE tools like laptop mats and air tube headphones designed to reduce direct EMF exposure.
22:02 — Bone Density and Phone Placement
Dave shares a DEXA scan showing about 15% lower bone density where he used to carry his phone in his pocket.
25:36 — Red Light Therapy Introduction
Dave recounts his early experience using red light therapy for whiplash and how quickly it changed his recovery.
28:06 — Red Light Science and Wavelengths
They explain the difference between visible red light for skin and near-infrared light for deeper tissues and mitochondrial ATP production.
31:00 — Red Light Dosing and Frequency
The group discusses irradiance, frequency of use, and why more sessions are not always better.
35:46 — Hair Growth and Red Light
They review research on red light caps for hair regrowth and why it does not trigger hair growth elsewhere on the body.
40:15 — PEMF Technology Explained
Dave distinguishes between lower-intensity state-based PEMF mats and higher-powered clinical systems that induce muscle contractions.
46:39 — Closing and Resources
They wrap with practical takeaways, discount information, and a reminder to use technology consciously rather than fearfully.
