What causes headaches?
Short answerHeadaches usually come from tension, dehydration, sleep loss, caffeine changes, or migraine triggers.

Headaches usually come from a mix of tension, dehydration, sleep loss, caffeine changes, eye strain, illness, hormones, or migraine triggers. A headache is a symptom, not a diagnosis.

Most ordinary headaches are not dangerous, but sudden severe pain, neurological symptoms, fever with stiff neck, head injury, or a headache pattern that is clearly changing should be taken seriously.

The useful question is not just ‘why does it hurt?’ but ‘what changed today?’ Food, sleep, stress, posture, and hydration solve more headaches than people expect.
