WEDNESDAY, March 4, 2020 (HealthDay News) -- If you have raging headaches and you spend a lot of time on your smartphone, a new study suggests you might want to put your phone down whenever you can.
Of course, this study can't prove that it's the smartphone that makes your headache worse, only that it might, the researchers said. And one headache expert said the study raises more questions than it answers.
"Although the cause of association of headache with smartphone use is not clear, this study finds an association of smartphone use in headache patients in terms of increased pill count and less relief with painkillers," said lead researcher Dr. Deepti Vibha. She's an associate professor in the department of neurology at All India Institute of Medical Sciences in New Delhi, India.
The report was published online March 4 in the journal Neurology Clinical Practice.
Dr. Heidi Moawad, of the department of medical education at Case Western Reserve University in Cleveland, co-authored an editorial accompanying the new report. She said, "These results raise an important issue because people rely so heavily on mobile devices."
The findings may prompt some people to try to cut back on using their smartphone, but that can be unrealistic for many people, even those who suffer from headaches, Moawad said.
"It's likely that the devices will be modified so that they can provide the same convenience without causing problems like headaches, eye strain or neck pain. Who knows -- maybe the technology will even be modified in a way that helps improve these issues," Moawad added.
For the study, Vibha and her colleagues collected data on 400 people with various types of headaches, including migraine and tension headaches. Participants were asked about their smartphone use, headaches and medications. In all, 206 used smartphones.
Compared with those who didn't use smartphones, people who used the devices were more likely to take painkillers for headaches (81% and 96%, respectively), and smartphone users took an average of eight pills per month, compared with five pills among those who didn't use smartphones.
Also, 84% of smartphone users said they got relief for their headache, compared with 94% of nonusers.
No difference between smartphone users and nonusers was seen in how often headaches occurred, how long they lasted or how bad they were, the study authors noted.
One limitation of the study is that the data were reported by the participants, so errors in memory might skew the data, the researchers said.
A headache expert who was not involved with the research stressed that this study is far from conclusive.
"In a very short period of time, cellphones have become extremely common, with a high rate of use not just for talking, but for shopping, reading mail, listening to music and watching media," said Dr. Noah Rosen, director of the Northwell Health Headache Center, in Great Neck, N.Y.
However, this study is highly speculative, Rosen said. Many factors that can influence headache and migraine, and access to care -- such as difference in education and socioeconomic status -- were not taken into account.
"Without fully controlling for these issues, this paper just leaves us with more questions," Rosen said. "It does teach us to be mindful of those things we use every day and how it may otherwise affect us."
