12 Hidden Signs of Dehydration That Aren't Just Thirst

2. Headaches - The Unseen Connection

Headaches are another common ailment that can be linked to dehydration. When the body is dehydrated, the brain can temporarily shrink from fluid loss, causing it to pull away from the skull and trigger pain receptors. Additionally, dehydration can lead to reduced blood flow and oxygen delivery to the brain, further contributing to headache development. Many people reach for painkillers at the first sign of a headache, but rehydrating with water or electrolyte-rich fluids may offer a more natural and effective solution. Understanding the connection between hydration and headaches can help individuals make more informed choices about their health.
