Cell phone use causes headaches.

the verdict
INSUFFICIENT LEANING
Recorded sources
3 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that cell phone use causes headaches?

Unclear. The placed sources only partially support the claim: a small clinical series reports ear symptoms after regular cell phone use, one cross-sectional study links late-night phone use to poor sleep with headaches as a correlated symptom, and a headache specialist says screen time can cause headaches. None of these directly establishes that cell phone use causes headaches in general.
