Plain English Summary
Researchers studied 155 military personnel exposed to radar frequencies of 8-12 GHz and 12.5-18 GHz to measure how electromagnetic fields affect melatonin (the sleep hormone) and serotonin (a mood chemical) in their blood. Workers exposed to the higher frequency range (12.5-18 GHz) showed significantly lower melatonin levels and higher serotonin levels, especially those with more than 10 years of exposure. This suggests that long-term exposure to certain radar frequencies can disrupt the body's natural hormone balance.
Why This Matters
This study provides compelling evidence that occupational EMF exposure can disrupt fundamental biological processes, specifically the delicate balance of hormones that regulate sleep and mood. The finding that higher frequency radar (12.5-18 GHz) produced significant hormonal changes while lower frequencies (8-12 GHz) did not suggests a frequency-dependent biological response. What makes this research particularly relevant is that these radar frequencies overlap with those used in 5G networks and airport security scanners that millions encounter daily. The fact that effects were most pronounced in workers with over 10 years of exposure points to cumulative biological impact over time. While most people aren't exposed to radar occupationally, this study adds to the growing body of evidence that EMF can measurably alter human physiology, challenging the industry narrative that non-ionizing radiation is biologically inert.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 8-12 GHz and 12.5-18 GHz

The study showed the EMF ability to influence plasma melatonin and serotonin concentration in radar workers, significantly in 12.5-18 GHz range with service period greater than 10 years.
