Abstract of the Annual Review of Research on Biological Effects of Electric and Magnetic Fields from the Generation, Delivery & Use of Electricity, San Diego, CA, 1997,

Subjects that reported frequent (more than one a day) to occasional (daily or several times a day) cellular telephone use had significantly lower mean urinary melatonin metabolite levels compared to those who reported infrequent (less than one per week) or no cell phone use. Results suggest that occupational cellular telephone use may be associated with reduced daytime melatonin production.
