Not all headaches are the same

Most adults get headaches occasionally. The cause might be dehydration, eye strain, stress, or something more complex like migraine disease.

Tracking when headaches start, how long they last, and what helps can make your next doctor visit much more productive.

Common headache types

  • Tension headaches: dull pressure on both sides, often linked to stress or poor posture
  • Migraines: throbbing pain, sometimes with nausea, light sensitivity, or aura
  • Cluster headaches: severe pain around one eye, often in cycles
  • Sinus headaches: pressure in the face, usually with congestion
  • Rebound headaches: from overusing pain relievers more than two to three days per week

Triggers worth tracking

Keep a simple log for two weeks. Note sleep hours, meals, screen time, caffeine intake, and weather changes. Patterns often appear faster than you expect.

  • Skipped meals or low hydration
  • Too much or too little caffeine
  • Irregular sleep schedule
  • Bright screens without breaks
  • Strong perfumes or smoke exposure
  • Hormonal shifts during menstrual cycles

Safe relief strategies

For mild tension headaches, rest, water, a cool compress, and gentle neck stretches may be enough. Over-the-counter pain relievers work best when taken early, not after hours of severe pain.

If you have diagnosed migraine, follow your clinician's plan. That may include prescription abortive medication and lifestyle changes.

When to see a doctor urgently

Seek emergency care for a sudden, worst-ever headache, headache with fever and stiff neck, confusion, weakness, or headache after a head injury.

Schedule a routine visit if headaches are increasing in frequency, waking you from sleep, or not responding to usual treatments.
