The short version
- The NHS says some people find certain triggers can cause migraine attacks.
- It suggests regular meals, staying hydrated, limiting caffeine and alcohol, regular exercise and plenty of sleep.
- A migraine diary can help you work out what might trigger your own attacks.
The triggers the NHS lists
- Having your period
- Anxiety and depression
- Stress and tiredness
- Skipping meals or not eating regularly
- Too much caffeine
- Not getting enough regular exercise
It is not known what causes migraine, and you are more likely to get it if a close family member has it. Having a trigger on this list does not explain every attack.
A steady day
These are the everyday steps on the NHS page, with help and advice from a GP:
- Eat meals at regular times
- Stay well hydrated
- Limit how much caffeine and alcohol you drink
- Get regular exercise
- Get plenty of sleep
- Try to manage your stress
- Try to keep to a healthy weight
- Try to avoid things you know trigger your attacks
Meals and sleep
Skipped meals and tiredness are both on the list, so they are worth noting even on days without a headache. Our suggestion is to record when you ate and how you slept alongside your attacks, then bring what you notice to a clinician. A pattern in a diary is a useful question, not a diagnosis.

Migraine Diary - Headache Log
Our app records attacks with possible triggers, symptoms and medication, then shows patterns in your entries over time.
We make this app, so we are not a neutral source. Free download with optional in-app purchases. Requires iOS 15.1 or later. The comparison shows two other approaches, so you can choose for yourself.
When to get medical help
The NHS says to see a GP if attacks are severe, getting worse or lasting longer than usual, if you have them more than once a week, or if they are hard to control. Ask for urgent advice if an attack has lasted longer than 72 hours or aura lasts longer than 1 hour at a time.
Call emergency services (999 in the UK, 911 in the US) for:
- a headache that came on suddenly and is extremely painful
- problems speaking or remembering things
- loss of vision, or blurred or double vision
- drowsiness, confusion or a seizure
- weakness in the arms or legs on one side, or on one side of the face
- a recent head injury
