Lifestyle factors and headache risk

Migraine and tension-type headache (TTH) are two of the most common and disabling primary headache disorders. Migraine affects roughly 12% of the population and is a leading neurological contributor to years lived with disability. A subset (~20%) experience aura, typically visual symptoms, before the headache phase. TTH is even more prevalent and is often described as bilateral, non-pulsating pressure or tightness, usually mild to moderate, with a heavy impact on work and daily function.

For therapists, these conditions show up in clinics as “headache plus”: neck pain, sleep disruption, stress dysregulation, reduced activity, and fear-driven deconditioning. Lifestyle advice is often part of care—but clinicians also need to know which lifestyle factors are truly associated with headache risk, and where the evidence remains uncertain.

A systematic review published in the Dec 2025 issue of the journal Medicine pulled together observational evidence on how lifestyle behaviors relate to the risk of developing migraine and tension-type headache (TTH). The key takeaway for clinicians is not that lifestyle is irrelevant—but that the evidence is uneven, with clearer signals for some exposures (stress/circadian disruption) and surprisingly weak pooled findings for others (alcohol, BMI), plus a major shortage of data for TTH.

What the pooled outcomes showed

Alcohol and migraine:
When data were pooled, alcohol use was not significantly associated with migraine risk overall (RR ~0.87; 95% CI crossed 1). The practical meaning: across populations, alcohol exposure does not show a stable “more alcohol = higher migraine risk” signal in the available observational studies. However, the studies were extremely inconsistent, which suggests the effect may depend on how alcohol is consumed (type, dose, binge patterns) and who is consuming it (genetics, co-triggers like poor sleep and stress). Clinically, alcohol may still be a reliable trigger for some individuals, but it does not emerge as a consistent population-level risk factor in pooled analysis.

BMI and migraine:
Similarly, pooled results showed no significant association between BMI and migraine risk (RR ~1.13; 95% CI crossed 1). This doesn’t “clear” weight as irrelevant; it indicates that BMI alone is a blunt indicator and may fail to capture what matters biologically (visceral fat, inflammatory phenotype, metabolic syndrome, hormonal context). For therapists, the implication is to focus less on BMI as a headline explanation and more on metabolic health behaviors that patients can change.

What the review found beyond pooled analyses (single-study signals)

Several clinically important exposures could not be pooled (too few studies), but showed notable associations in individual datasets:

• Smoking and migraine: One study reported smoking was associated with higher migraine risk (RR ~1.30). This is consistent with broader health risks and gives clinicians a defensible “risk marker” message even while acknowledging limited data.
• Physical activity: Findings were mixed. Some evidence suggested exercise could be protective (lower migraine risk), while other evidence hinted heavy physical activity/workload might increase risk. For practice, this supports a “dose and context matter” approach: moderate, consistent activity tends to help; abrupt spikes, high workload, poor recovery, or dehydrating conditions may aggravate vulnerability.
• Workplace stress: High job demands, low job control, and low social support were associated with higher migraine risk in one cohort. This aligns with a biopsychosocial view where stress load and reduced autonomy drive sensitisation, sleep disruption, and poorer recovery capacity.
• Shift work and circadian disruption: Shift work was associated with higher migraine incidence in one study, with sleep disturbances interacting with risk. For therapists, this is one of the most actionable findings: regularity of sleep-wake timing and recovery rhythms likely matters.
• Composite “healthy lifestyle” pattern: A healthy lifestyle score (including diet quality and regular sleep patterns) was associated with a meaningful reduction in migraine risk (about 19% lower risk in one prospective cohort). This supports counseling patients on bundles of habits rather than obsessing over a single trigger.

Tension-type headache: the big evidence gap

For TTH, the review found very limited data. In the single study available, smoking, physical activity, and alcohol were not significantly associated with TTH risk (confidence intervals crossed 1). The most important clinical message is: we do not yet have enough strong observational evidence to quantify lifestyle–TTH risk relationships, even though lifestyle modification is commonly advised in care.

Clinical implications you can use tomorrow

1. Avoid blanket claims like “alcohol causes migraine” or “higher BMI predicts migraine.” The pooled evidence doesn’t support those as universal rules.
2. Prioritise circadian regularity and sleep stability, especially for shift workers—this appears consistently plausible and clinically actionable.
3. Treat stress context as a core risk domain (job strain, low control, low support). Rehabilitation plans should include recovery skills, pacing, and down-regulation strategies, not only exercise dosage.
4. Prescribe activity with attention to dose-response: build consistency, avoid boom–bust patterns, and tailor intensity to recovery capacity.
5. Use a “bundle” approach: sleep regularity + moderate activity + diet quality + reduced sedentary time will likely outperform single-factor advice.
