Devices designed to mitigate exposure from cellular devices are accessories marketed to reduce the amount of electromagnetic field (EMF) radiation absorbed by the user. These shielding products often incorporate materials intended to deflect or absorb radio frequencies emitted by mobile phones. The effectiveness of these cases varies significantly based on design, materials used, and the specific frequencies being targeted.
The perceived need for shielding accessories stems from concerns regarding potential health risks associated with prolonged exposure to EMF radiation. Historically, anxieties about radiofrequency exposure have fluctuated alongside technological advancements in wireless communication. Consequently, the demand for mitigation strategies has increased, despite scientific consensus remaining divided on the extent of actual harm posed by typical cellular device usage.
