Wi-fi router
For creating a low EMF sleep environment
The experts we follow agree on this.
Turning off your Wi-Fi router at night is a simple way to reduce EMF exposure.
Who is behind it
Voices including a Princeton-trained molecular biology PhD, a clinical nutritionist and an optometrist of twenty years.
How strong the research is
Mostly expert experience so far, with published research still catching up.
In their words
“I already routinely do this shut up your Wi-Fi router at night there's no reason you need Wi-Fi at night your phone should be bare minimum 12 feet away from you ideally in airplane mode”
a board-certified cardiologist
Wi-Fi routers emit EMFs that can negatively affect health; turning them off at night reduces exposure and can improve symptoms such as chronic pelvic pain.
Turning off Wi-Fi reduces non-native EMF exposure during rest periods, supporting nervous system regulation.
Minimising EMF exposure at home is advised to reduce potential health risks.
