EMF (electromagnetic field) exposure can interfere with calcium channel signaling, which is the most common genetic risk factor for autism. This talk will present a simplified process for systematically reducing EMF and wireless radiation to calm the sensory environment and reduce the known health effects, many of which match the primary symptoms of autism. The first emphasis will be on improving the sleep environment. Some of the reduction methods are free, easy to implement, and can yield significant results very quickly. A protocol for tracking exposures and symptoms will be presented, along with some recommended consumer meters for measuring magnetic fields, electric fields, dirty electricity, and wireless radiation. Professional resources to help with more complex environmental issues will also be shared.
