What is the cause of a headache?

Answer 1

Annoying or loud noises. Annoying noises would be young children in the back of the car or other passangers distracted you from your driving. A loud noise could be that of honking horns if you're on a jammed highway. Those are just two examples. Stress of carful driving could do it too.

Answer 2

There are several possible causes, from internal (blood flow, stress) to external (noises, light) .

Stress causes higher blood pressure. Dehydration decreases blood flow and affects the fluid your brain is suspended in inside your skull. High sodium increases blood pressure. Also caffeine withdrawal, as when you're going through caffeine withdrawal your blood pressure goes up.

To clarify, blood pressure is the force blood exerts on the walls of arteries and veins. Higher blood pressure makes veins and arteries expand and the brain has a limited amount of unfilled space. Veins and arteries expand and constrict as needed partially depending on the pressure in them.

When you have bright sunlight coming down on you and you also have the AC on, your nerves don't like it because it's cold, against hot. If you don't have the air conditioning on, it might be that you are dehydrated or something. And if you aren't sweating or you have the AC on, it probably means that the sun is still bright even when you're looking at it with sunglasses on and your optical nerves don't like that. >.<
