Specific Absorption Rate (SAR) is a measure of the rate at which radiofrequency energy is absorbed by the human body when exposed to a radiofrequency electromagnetic field. In the context of mobile phones, SAR values indicate the maximum amount of radiofrequency energy a user could be exposed to when using the device. Mobile phones with minimal radiofrequency energy absorption offer potentially reduced exposure to electromagnetic fields during use.
The appeal of handsets exhibiting lower SAR values lies in the perceived health benefits associated with minimizing radiofrequency exposure. While regulatory bodies set maximum permissible SAR levels to protect consumers, some individuals seek devices that fall significantly below these thresholds, often driven by concerns regarding long-term exposure effects. The development and availability of these devices reflect a growing consumer awareness and demand for options perceived as safer or healthier.
