This module explores the essential—and often overlooked—intersection of building all-electric, high-performance homes and reducing exposure to Electromagnetic Radiation (EMR). You'll learn why most tight, energy-efficient homes are built without gas appliances, and how to avoid dangerous backdrafting. But you’ll also dig deeper into how going all-electric can inadvertently increase EMR exposure—and what to do about it. We’ll cover the different types of EMR (RF, magnetic fields, electric fields, and microsurge electrical pollution), their biological effects, how to test your sensitivity with a simple EMR sabbatical, and what tools and experts can help you evaluate your home’s EMR load. If you're striving for a truly healthy home—especially for the EMR-sensitive—this module gives you the foundational knowledge to create a safe, low-radiation environment, starting with your sleep sanctuary.
