Abstract Stress proteins are important in protection during cardiac ischemia/reperfusion (cessation and return of blood flow) and are reportedly induced by electromagnetic (EM) fields. This suggests a possible ischemia protection role for EM exposures. To test this, chick embryos (96 h) were exposed to 60 Hz magnetic fields prior to being placed into anoxia. Survival was 39.6% (control), and 68.7% (field‐exposed). As a positive control, embryos were heated prior to anoxia (57.6% survival). We conclude that: 1) 60 Hz magnetic field exposures reduce anoxia‐induced mortality in chick embryos, comparable to reductions observed following heat stress, and 2) this is a simple and rapid experiment to demonstrate the existence of weak EM field effects.
