EFEIA Foundation reports: The first systematic international survey of electromagnetic hypersensitivity finds sleep disruption explains 40% of symptom variance. The survey also identified eight distinct EHS phenotypes and found women bear 88% of severe cases.
"The very symptoms we're trying to measure prevent people from completing the measurement."
"Sleep disruption is the canary in the coal mine. It's often the first system to show strain, and it's where we can most clearly observe the effects of electromagnetic exposure on biology."
