Dehydration can lead to headaches largely because of its effects on the brain and its surrounding protective layers. The brain is composed mostly of water, and when the body becomes dehydrated, it loses fluid from all its tissues — including the brain. As water levels drop, the brain can slightly shrink or contract within the skull.
This shift creates tension on the meninges, the thin, sensitive membranes that envelop the brain and spinal cord. The meninges have pain-sensitive nerves, and when dehydration causes the brain to pull away from the skull, these membranes stretch, triggering discomfort or pain that we recognize as a dehydration headache.
In addition, dehydration reduces blood volume, which can decrease oxygen and nutrient delivery to the brain. This further contributes to the sensation of a headache and can intensify other symptoms like fatigue, dizziness, or difficulty focusing.
