Retrospective study of smartphone usage effects on tension-type headache prevalence in young adults.

Tension-type headache (TTH) is rising among young adults, potentially linked to increasing smartphone use. This retrospective study investigated the association between smartphone usage and TTH among 120 participants aged 18-30 years. Individuals with screen time exceeding 4 hours/day reported significantly more frequent and severe headaches. Posture and type of smartphone activity also influenced headache intensity. Thus, the findings call for behavioral interventions to mitigate TTH risk.
