The headache is one of the most common ailments faced by people over the world. What causes it? Here are a few pointers to what triggered your headache:
- Bright and flickering lights cause increase in the levels of certain chemicals in the brain that may trigger a headache.
- When you relax after a particularly stressful period, your body relaxes causing a headache. Next time you have a headache over the weekend, think about stress levels during the week.
- Cigarette smoke contains nicotine that narrows blood vessels in the brain. Being around cigarette smoke may trigger a headache.
- The odour of a strong perfume stimulates the nervous system, and that may cause a headache.
