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.

Higher digital screen exposure is associated with approximately 60% greater odds of migraine or headache The current body of evidence comprises 1 study and 1 meta-analysis. EvidenceHub rates the overall confidence at 24/100 (low).
The Claim
Higher digital screen exposure is associated with approximately 60% greater odds of migraine or headache
This conclusion is most relevant to: Adolescents and adults with migraine or primary headache (22 studies, N=14,763; pooled analysis N=11,218).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Digital screen exposure and migraine burden: a systematic review and meta-analysis. (Journal of neurology, 2026) —
How It Works
The proposed biological pathway:
- ▸Blue light activates retinal ganglion cells
- ▸Melatonin suppression and circadian disruption
- ▸Trigeminovascular/cortical hyperexcitability
- ▸Increased migraine/headache risk
Who Might Benefit
Evidence fit by population:
- ▸Adolescents and adults with migraine or primary headache (22 studies, N=14,763; pooled analysis N=11,218)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Self-reported, cross-sectional exposure measurement
- ▸Residual confounding and possible publication bias (Egger's test p=0.002)
- ▸Low certainty of evidence (GRADE)
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.
