Higher digital screen exposure is associated with approximately 60% greater odds of migraine or headache

A meta-analysis of 10 studies (N=11,218) found that higher digital screen exposure was associated with significantly greater odds of migraine/headache (pooled OR 1.60, 95% CI 1.38-1.86, p<0.001). The association was consistent in adult (OR 1.87) and pediatric/adolescent (OR 1.46) subgroups, but certainty of evidence was low due to cross-sectional design and potential bias.

Frequently Asked Questions

Does screen time increase migraine risk?▼

Yes, higher digital screen exposure is associated with about 60% greater odds of migraine or headache, but the evidence is low certainty and mainly from cross-sectional studies.

What is the pooled odds ratio for screen exposure and migraine?▼

The pooled odds ratio is 1.60 (95% CI 1.38-1.86), indicating a significant association.

Is the effect stronger in adults or children?▼

The effect appears stronger in adults (OR 1.87) than in pediatric/adolescent populations (OR 1.46), but both are significant.

What mechanisms link screen exposure to migraine?▼

Proposed mechanisms include blue light-induced retinal ganglion cell activation, melatonin suppression and circadian disruption, and trigeminovascular/cortical hyperexcitability.
