EMF Exposure & Health

EMF exposure remains an active area of scientific research. While regulatory bodies maintain that current exposure limits are safe, independent research has raised questions that lead many to take precautionary steps.

What research shows
Sleep Quality: Multiple studies have found measurable effects on sleep quality and brain activity during sleep from RF-EMF exposure, though effect sizes vary across studies.
Children: Some researchers recommend lower exposure limits for children, citing developing nervous systems and longer lifetime exposure as factors warranting extra caution.
Precautionary Principle: Many health-conscious individuals choose to minimize EMF exposure based on the precautionary principle: when science is uncertain but potential consequences are significant, reducing exposure is a reasonable choice.
