Does Dehydration Cause Headaches?

If you’ve ever asked yourself the question, “does dehydration cause headaches?”, then we’re here to provide a very simple answer.

Yes. Dehydration does indeed cause headaches. Even the teeniest bit of dehydration can cause you to have a mild headache, and any prolonged lack of moisture will cause some massive headaches that are borderline debilitating.

How Does Dehydration Cause Headaches?

The human body requires a healthy balance of fluid and electrolytes. Without this healthy balance, we won’t be able to function properly, and because we constantly lose water everyday by sweating and urinating, among other things, it’s necessary for us to constantly replenish ourselves with water and other fluid-rich foods.

Most of the time, this is not that big of a problem. Potable water is readily accessible to most people these days. Also, it’s a common habit among many people to drink water every now and then, when they go to the kitchen or the office pantry.

Unfortunately, there are times when the body loses far more water than necessary. When these happens, we can become dehydrated. This can then lead to many types of complications, including but not limited to, dehydration headaches.

You see, when our bodies are not hydrated properly, our brains can sometimes shrink from the lack of fluid. This causes the brain to start pulling away from the skull, causing the kind of pain that leads to dehydration headaches.

Usually, rehydrating your body should cause your brain to plump right back up and relieve the headache.

Who Are at Risk for Dehydration Headaches?

Everyone can get dehydrated. It doesn’t matter when, who, or where. So long as you don’t constantly replenish the fluids that you lost and don’t drink water when you’re thirsty, you’re bound to get a dehydration headache.

Even if that is so, there are individuals who are at a higher risk of dehydration compared to others, such as:

  • People living in higher altitudes. Just being a higher altitudes can cause you to lose more water than usual.
  • Younger children, as well as infants. Because, other than then not having developed a habit of constantly drinking water yet, most infants and young children are always on the move, causing them to lose more water compared to adults. Not to mention, they need more water compared to the average adult.
  • Elderly people.
  • People who are suffering from diabetes, kidney disease, as well as other types of chronic illnesses.
  • People whose medications cause them to urinate more frequently.
  • Endurance athletes.
  • People living in hot or warmer climates.

If you belong to any one of these groups of people, it’s important that you take proper care of yourself and make sure that you keep yourself hydrated at all times.

As you can see, dehydration headaches are a real thing. They’re not something you should take lightly either.

Going forward, make it a point to take better care of yourself and to remind yourself the importance of being hydrated all of the time. This is especially important if you’re an active person who is always on the go.
