Headaches comes in a variety of forms for a number of different reasons. One such common cause of chronic headaches is due to dehydration. In today’s blog, we take a closer look at why dehydration can cause headaches to develop, and the best ways to prevent these types of headaches.
Your body operates optimally when it has the correct level of fluids in it. Your body does a pretty good job of getting rid of excess fluid through sweat and urination, but it can’t force you to consume more liquids. The thirst sensation is the best your body can do to help tell your brain that you’d benefit from hydrating. But why exactly is a dehydrated body more prone to headaches?
Why Dehydration Causes Headaches
If you are running low on fluids and electrolytes, it can cause a physical reaction in the brain. Being dehydrated can cause the brain to temporarily contract due to fluid loss. When this happens, the brain pulls away from the skull, which can trigger a pain sensation that manifests in the form of a headache. Once your body is rehydrated, the brain can return to its normal state, relieving tension and helping to control headache symptoms.
Symptoms a dehydration-based headache include but are not limited to:
- Pain in the forehead region
- A throbbing sensation
- Lowered blood pressure
- Dizziness
- Confusion
- Rapid heart rate
- Sensitivity to light
Your body will send some passive signals to tell you to increase your fluid intake, like by creating the thirst sensation or with dark colored urine. This is a sign that all bodily functions would operate better if you increased your fluid intake.
Preventing and Treating Dehydration Headaches
If you’re suffering from headaches, one of the simplest ways to see if they respond to conservative care is to really work to increase your fluid intake and stay hydrated. Your headaches may not stem from a major neurological issue, you could just be dehydrated. This is a good thing, because it’s easily fixable. Some ways to remain hydrated throughout the day include:
Drinking More Water – Strive to drink 6-8 glasses of water a day to help stay hydrated. Better yet, invest in a large water bottle or canister that makes it clear how much water it can hold. Make it a goal to finish a certain amount of refills every day.
Eating Fiber-Rich Foods – Fiber-rich foods like fruits and vegetables, especially things like cucumbers and watermelon, have very high water content. You can stay hydrated through your food choices so reach for fiber and limit salt intake.
Avoid Caffeine and Alcohol – While on the surface it may appear that these beverages are helping to increase your fluid intake, they actually promote urine output, which can put you at risk of becoming dehydrated.
Be Mindful of Fluid Output – If you’re sweating a lot during a workout or losing fluids because you are in the bathroom frequently with a stomach bug, know that you need to replenish these fluids. Monitor your fluid loss and really work to increase your intake if you’re losing more than normal.
If you can do all these things, you just may find it a little easier to get control over your chronic headaches. However, if they don’t address the discomfort, there may be more going on than meets the eye, and you may benefit from a consultation with a pain management and headache specialist like Dr. Cohn.
