Abstract

Insomnia at baseline is associated with a 1.58 times higher risk of new onset of migraine three years later.

  • Chronic headache risk increases by 2.02 times and medication-overuse headache risk increases by 3.79 times with insomnia at baseline.
  • Shift work disorder (SWD) at baseline is linked to a 1.64 times higher risk of new onset of migraine.
  • Restless legs syndrome (RLS) at baseline is associated with a 1.55 times higher risk of experiencing headache at least one day per month and a similar risk of migraine.
  • Work-related factors, such as work schedules and number of night shifts, do not predict the onset of headaches over three years.
