Background: Many studies have shown that electromagnetic field (EMFs) decrease anxiety. In this study we studied the effect of low frequency electromagnet fields on decreasing the induced anxiety by histamine in mice.

Methods: 32 male albino mice at the weight of 30gr were classified in 4 groups (n=8), and were injected histamine (5mg/kg) 3 group of them were exposed to electromagnetic field with 25, 50, 75HZ & frequency with intense 250µT for 10min before injection. After 5 minutes, anxiety signs in the 3 exposed groups were compared with control group.

Results: Analysis showed a significant increase in OAT (open arm times, p<0.001) in 75 HZ and OAE (open arm entries) in 50 & 75 HZ (p<.005) as were measured in T-Maze.

Conclusion: EMEs in low frequency can effect on induced anxiety by histamine
