• Electromagnetic Hypersensitivity (EHS): Some individuals experience a range of symptoms, such as headaches, skin rashes, and fatigue, upon exposure to EMFs.

Strategies for Building Low-EMF Environments

Creating a low-EMF environment involves identifying and mitigating EMF sources. Here are some practical strategies you can implement:

1. Distance is Your Friend

The intensity of EMFs decreases rapidly with distance. Increase the distance between yourself and EMF sources whenever possible.

• Example: Keep your cell phone away from your body, especially when making calls. Use speakerphone or a wired headset.
• Example: Place your Wi-Fi router in a location where you don't spend much time, such as a hallway or utility room.
• Example: Maintain a safe distance from high-voltage power lines and electrical substations.

2. Minimize Wireless Device Usage

Limit your exposure to RF EMFs by reducing your use of wireless devices.

• Example: Use wired internet connections (Ethernet) instead of Wi-Fi whenever possible. Disable Wi-Fi and Bluetooth on your devices when not in use.
• Example: Turn off your cell phone at night or place it in airplane mode. Avoid keeping your cell phone in your bedroom.
• Example: Consider using a wired keyboard and mouse instead of wireless ones.

3. Hardwire Your Home or Office

Replace wireless connections with wired alternatives to reduce RF EMF exposure.

• Example: Use Ethernet cables to connect computers, printers, and other devices to the internet.
• Example: Install wired security systems and home automation devices.
• Example: Opt for wired telephones instead of cordless phones.

4. Shielding Techniques

Shielding involves using materials to block or reduce EMFs.
