Researchers exposed mice to 26 MHz radiofrequency radiation that raised their body temperature by 2°C, finding it caused a drop in immune cells and suppressed immune function. The radiation triggered stress hormone release and altered the distribution of immune cells throughout the body. This suggests RF radiation can weaken immune defenses through heat-related stress responses.
