Dec 10, 2025
Daniel DeBaun, a telecom engineer and founder of DefenderShield, dives into the hidden dangers of electromagnetic fields (EMFs) in our everyday lives. He discusses how EMFs impact women's health, fertility, and kids' brains, especially from devices like phones and laptops. Daniel shares practical advice for reducing EMF exposure at home, including using shielding products and establishing strategies for a low-EMF bedroom. He explains the risks associated with Bluetooth wearables and emphasizes the importance of distance in protecting our health without going off-grid.

Episode notes
How DefenderShield Began
- Daniel DeBaun started building shielding after noticing his sons used laptops on their laps and seeing research linking laptops to reduced sperm mobility.
- He produced laptop shields that friends wanted, then scaled to sell to the public when demand grew.
Shielding Absorbs, Doesn’t Just Reflect
- DefenderShield products absorb RF energy and dissipate it as very low heat rather than reflecting it back.
- The material converts captured signals to heat so the energy doesn't pass through to the body.
Standards Were Designed For Heat, Not Biology
- Regulatory limits focus on thermal effects, not long-term biological impacts from pulsed RF exposure.
- Low power levels over long durations can still produce biological changes in cells according to research.
