常見 Headache Triggers
Identify what might be causing your headaches.
點解呢個 事情
Understanding what triggers your headaches is the first step to preventing them. While triggers vary from person to person, identifying your personal triggers can help you avoid or manage them, reducing headache frequency and severity.
What Are the Most Common Triggers?
These are the most frequently reported headache triggers:
Stress and tension
Emotional stress is one of the most common headache triggers. This includes work pressure, family concerns, anxiety, and even the “let-down” period after stress ends (like weekends or holidays).
American Migraine Foundation
Sleep problems
Too little sleep, too much sleep, irregular sleep schedules, and poor sleep quality can all trigger headaches. Maintaining a consistent sleep routine is important.
National Headache Foundation
Dehydration and skipped meals
Not drinking enough water or skipping meals (causing low blood sugar) are common triggers. Regular hydration and consistent meal times can help prevent headaches.

Certain foods and drinks
Common culprits include aged cheeses, processed meats, alcohol (especially red wine), caffeine (too much or withdrawal), chocolate, and foods containing MSG or artificial sweeteners.

Environmental factors
Bright lights, flickering screens, loud noises, strong smells (perfume, smoke, chemicals), and changes in weather or barometric pressure can trigger headaches in sensitive individuals.

Hormonal changes
For women, fluctuations in estrogen during menstrual cycles, pregnancy, and menopause can trigger headaches. This is particularly common with migraines.

How to Identify Your Triggers
The best way to identify your headache triggers is to keep a headache diary. Record when headaches occur, what you ate, how you slept, stress levels, and other factors. Over time, patterns will emerge.
Track consistently
Record details every day, not just on headache days. This helps you spot patterns more clearly.
Note timing
Write down when headaches start, how long they last, and their intensity. This helps distinguish between different types of headaches.
Record potential triggers
Include food and drink intake, sleep duration, stress levels, weather changes, and any medications taken.
Share with your doctor
Bring your headache diary to medical appointments. It provides valuable information your doctor can use to refine your treatment.
