Research on EMF in home office environments - laptops, WiFi, monitors, and printers.
## Home Office EMF Sources The modern home office represents one of the most EMF-dense environments in our daily lives. Whether you're working from a kitchen table or a dedicated office space, you're likely surrounded by multiple wireless devices operating simultaneously within a few feet of your body. Your laptop emits radiofrequency radiation from its WiFi antenna, often positioned just inches from your hands and torso.

Researchers exposed aged mouse cells to 50 Hz magnetic fields (the same frequency as power lines) and found the exposure promoted cancer-like changes. However, when they treated the cells with metformin, a diabetes drug, it blocked these harmful effects by reducing inflammation pathways. This suggests power line frequency EMF may be particularly concerning for older adults.
