What is a dehydration headache?

A dehydration-related headache happens when your body doesn’t get enough fluids. Even mild dehydration can cause a headache. Usually, other symptoms of dehydration (such as fatigue, dizziness, extreme thirst and dry mouth) appear along with headache pain.

Dehydration headaches often get better with at-home remedies like drinking water, resting and taking over-the-counter pain relievers. If you have signs of severe dehydration (such as confusion or dizziness), get medical help right away.
