Researchers exposed Chinese hamsters to 2450 MHz microwave radiation (the same frequency as microwave ovens and WiFi) for 14 hours daily over 20 days.

Soviet researchers in 1976 studied how alternating magnetic fields affect the body's stress response system, specifically the pituitary-adrenal axis. They found that extremely low frequency (ELF) magnetic fields can trigger measurable changes in this critical hormonal pathway that controls our response to stress. This suggests that common EMF sources in our environment may be activating stress responses in our bodies without us realizing it.
