Signs & Symptoms of a Dehydration Headache

A dehydration headache can feel different from other types of headaches, such as tension headaches or migraine. The pain is often:

  • Dull or Throbbing: Many describe it as a persistent, aching sensation.

  • Worse With Movement: Simple activities, such as walking, bending down, or standing up, may intensify the pain.

  • Located in the Front or Back of the Head: The pain may be widespread or concentrated in one area, commonly at the forehead, temples, or back of the head.

  • Accompanied by Other Dehydration Symptoms: These symptoms may include dry mouth, dizziness, dark urine, fatigue, or confusion.

What Causes a Dehydration Headache?

Your body needs water to function properly. When you don’t drink enough fluids, your body loses essential electrolytes and your brain can temporarily contract or shrink due to fluid loss. This shrinkage triggers pain receptors, leading to a headache. There are several factors that can increase your risk of dehydration and headaches. This includes not drinking enough water, excessive sweating, illnesses with vomiting and diarrhea, and overconsumption of caffeine or alcohol. 

The duration of a dehydration headache can vary depending on how quickly you rehydrate and how severe your dehydration is. Typically, a mild to moderate dehydration headache can last anywhere from a few hours to a full day.

How To Relieve a Dehydration Headache

If you suspect your headache is due to dehydration, the best course of action is to rehydrate as soon as possible. Here are some effective ways to relieve the pain:

  • Drink Water: Slowly sip water instead of chugging large amounts all at once to allow your body to absorb the fluids properly.

  • Electrolyte Drinks: If you are experiencing dehydration due to exercise, illness, or excessive sweating, electrolyte-replanishing drinks can help.

  • Rest: Be sure to get plenty of rest in a cool, dark room. Reducing exposure to bright lights and heat can help ease symptoms.

  • Eat Water-Rich Foods: Foods that have a high water content, like watermelon, cucumbers, and celery, can provide extra hydration.

If your headache persists even after rehydrating, or if you experience severe dehydration symptoms, seek prompt medical attention. A healthcare provider can administer IV fluids to quickly restore fluid loss.
