Migraines usually happen because the brain is unusually sensitive and overreacts to certain triggers like hormones, stress, sleep changes, and sensory overload, on top of an underlying genetic tendency to get migraines. They are not your fault, but understanding your personal triggers can often reduce how often and how intensely you get them.

What migraines are

  • Migraines are a neurological condition where abnormal brain activity and nerve pathways cause moderate to severe throbbing head pain, often on one side, with nausea and sensitivity to light and sound.
  • Changes in brain chemicals like serotonin and pathways involving the trigeminal nerve (a major pain nerve in the head) are thought to play a key role.

Big-picture reasons you get them

  • Genetics: Migraines often run in families, and many people with migraines have close relatives who get them too.
  • Brain sensitivity: The migraine brain is more reactive , so normal things (like a skipped meal or bright light) can trigger a pain cascade more easily than in people without migraines.
  • Age and sex: Migraines commonly start between ages 10 and 45 and are more frequent in women, partly due to hormonal factors.

Common triggers (why your attacks start)

These are patterns many people with migraines report:

  • Hormones: Estrogen ups and downs around periods, pregnancy, or perimenopause can trigger attacks or change their pattern.
  • Stress: Daily stress and “letdown” after stress (like weekends after a hard week) are powerful triggers for many.
  • Sleep changes: Too little, too much, or irregular sleep, including shift work or jet lag, can set off migraines.
  • Food and drink: Alcohol (especially red wine), too much or withdrawal from caffeine, skipping meals, and certain foods like aged cheese or processed foods can trigger attacks.
  • Sensory overload: Bright or flashing lights, loud noises, and strong smells like perfume, smoke, or chemicals can spark migraines.
  • Physical strain: Intense or unfamiliar exercise, neck and shoulder tension, or just being very overtired can bring one on.
  • Environment: Weather or barometric pressure changes, and sometimes high altitudes, can be triggers in susceptible people.

When to be concerned

  • Seek urgent care if a headache is sudden and “worst ever,” follows a head injury, comes with confusion, weakness, trouble speaking, or vision loss, since those can signal something more serious than a typical migraine.
  • Talk to a healthcare professional if your migraines are frequent, changing, or interfering with work, school, or daily life, because there are now targeted treatments (like triptans, CGRP-blocking meds, and preventives) that can significantly reduce attacks.

What you can do next

  • Keep a headache diary (time, food, stress, sleep, hormones, weather) to spot your own patterns and triggers.
  • Bring that diary to a clinician so they can confirm it is migraine, rule out other causes, and help plan both quick-relief and preventive treatments tailored to you.
