Smartphones may make your headaches worse, study finds

(CNN)If you think the time spent on your smartphone could be contributing to a relentless headache, you might be right, a new study finds.

That was the possible case for a group of subjects in India who were studied to determine the association between smartphone use and new headaches, or increased severity. Although there are anecdotal stories suggesting a link between technology use and pain, there is limited evidence on the relationship between smartphones and pain, the report said.
The researchers studied 400 people with a primary headache condition, which includes migraines, tension headaches and other types not caused by another illness. After asking the participants about their smartphone use, headache history and medication use, they found that smartphone users were more likely to use more pain medication but find less relief compared to those who didn't use smartphones.
    "The associations found in the study do prompt the possibility that smartphone use may be a potential trigger for headache worsening, and there might be unexplored mechanisms which future studies may unravel," said Dr. Deepti Vibha, study author and associate neurology professor at All India Institute of Medical Sciences in New Delhi.
