- Invest in blue light-blocking glasses.
- Reduce screen time before bed to support better sleep.
- Incorporate eye exercises and stretches to reduce tension.
5. Dehydration and Electrolyte Imbalance
Even mild dehydration can lead to headaches by reducing blood flow to the brain. Inadequate hydration can also create electrolyte imbalances that contribute to nerve dysfunction and pain.
How do you prevent exposure to this trigger?
- Drink water consistently throughout the day.
- Eat hydrating foods like cucumbers, oranges, and watermelon.
- Maintain electrolyte balance by consuming potassium- and magnesium-rich foods.
How do you deal with this trigger for immediate relief?

- Check your urine color to monitor hydration levels (aim for pale yellow).
- Avoid excessive caffeine and alcohol, which can dehydrate you.
- Set reminders to drink water regularly.
6. Caffeine — Both Too Much and Too Little
Caffeine can be a double-edged sword. While small amounts may provide headache relief, excessive consumption or sudden withdrawal can trigger migraines. Pain management for headaches often involves regulating caffeine intake to find a balance that minimizes headache risk.
How do you prevent exposure to this trigger?
- Stick to a consistent caffeine intake without drastic increases or decreases.
- Limit caffeine consumption in the afternoon to prevent sleep disturbances.
- Stay hydrated to counteract caffeine’s diuretic effects.
How do you deal with this trigger for immediate relief?
- If withdrawing, drink a small amount of caffeine to ease symptoms.

- Maintain a steady morning caffeine routine rather than sporadic consumption.
7. Poor Posture and Neck Tension
Sitting for long periods with improper posture, especially at a desk or while using a phone, can lead to tension headaches. Muscle strain in the neck and shoulders can contribute to pain radiating to the head.
How do you prevent exposure to this trigger?
- Maintain proper posture when sitting and standing.
- Adjust your workspace ergonomically to support your neck and spine.
- Take frequent breaks to stretch and move.
