Why do I have a headache?

Most headaches are 'primary' — a condition in themselves, not a symptom of something sinister — and daily routines frequently hold the clues.

The everyday suspects

Tension-type headache (a tight band around the head) is the most common and is often linked to stress, posture and long screen hours. Dehydration, skipped meals, poor sleep, eye strain and caffeine withdrawal are frequent, fixable contributors.

Migraine is a different pattern

Migraine tends to be one-sided, throbbing, worse with movement, and often paired with light or sound sensitivity or nausea. Identifying personal triggers — irregular sleep, certain foods, bright light — is central to reducing episodes.

The trigger diary advantage

Noting sleep, hydration, meals, screens and stress for two weeks often reveals a personal pattern that no generic advice could. This single habit changes most headache conversations with doctors.

Red flags — seek urgent care

A sudden 'worst-ever' thunderclap headache, headache with stiff neck and fever, weakness, confusion, vision loss, or headache after a head injury are emergency patterns — don't wait these out.

Everyday takeaways
  • Hydrate and eat on a regular rhythm
  • Follow the 20-20-20 screen rule
  • Keep sleep and wake times steady
  • Log two weeks of triggers before your doctor visit
