Large Meta-Study Links Cellphones to Headaches

Over the decades that cell phones have been gaining such widespread popularity, minor side effects of cell phone use, such as headache, sleep disturbance, lack of concentration, impairment of short-term memory, dizziness, tinnitus, fatigue, and benign warming of the ear have been reported. Headache is common pain syndrome that has reportedly been increasing with more widespread cell phone usage.

In a report filed on the U.S. National Library of Medicine, a study was done to determine if cell phone use could indeed cause headaches. Headaches have been loosely tied to excessive cell phone use in the past, but studies have been producing conflicting results. This can be likely be explained by small study populations that were not of sufficient power to indicate benefit or harm. Thus, to gain a better understanding of the relationship between cell phone use and headache, the study was performed using a quantitative meta-analysis of cross-sectional studies in order to more accurately appraise the association between cell phone use and headache.

The studies investigating the association between cell phone use and headache were then thoroughly evaluated. A total of 2,699 articles were identified and assessed. The results of the meta-analysis and many previous studies supported current clinical opinion that cell phone use may cause increased risk for headaches. Therefore, the study said, it is advisable to admit that the use of cell phones is a risk factor for headache.
