Can Dehydration cause a Headache?

Can Dehydration cause a Headache?

Can dehydration cause a headache? Yes! And for me, dehydration triggers a migraine.  The good news is that it is avoidable. The bad news is that it is often overlooked.  Usually, I have a water bottle around (in the car, where I’m siting, at my desk and classroom) but realized I wasn’t drinking it.  This was a problem.  I have a couple new tricks I’m trying.

Track Water Intake

I bought a Thermos Smart Lid water bottle to help track digitally. I track my migraine both digitally and paper/pencil, but I think this water bottle and app will give me an accurate reading.  Water bottles are usually left all over the house and having only one option to drink from seemed less wasteful and more efficient.

The water bottle comes with an app that tracks ounces consumed, hours you have drunk and sips.  It shows the temperatures of the water along with the activity.  You can customize your goal or use the suggested goal according to your personal statistics.

So far, the app has been helpful in tracking and understanding if my migraine is triggered by dehydration.  Not all triggers are avoidable but hydration is.  I think that this will help with my overall battle.

Hydration tablets

hydration for headache and migraine







When I think heat is going to be an issue, I use hydration tablets on vacations and situations sweaty situation.  I overheat easily and always keep a tube of NUUN tablets to drop in my water to get a boost of electrolytes.

How do you get rid of dehydration headache?

I have not used them on a normal basis until now.  Even mild dehydration can trigger my migraine which can occur everyday.  I have started using NUUN tables after my workouts to have added electrolytes and hydration on top of my already increased water.  According to NUUN, “Dehydration cannot only lead to decreased performance, but it can cause muscle cramping, headaches, nausea, and fatigue.”

If you dehydrate easily, like me, avoid caffeine and alcohol while increasing your fruit and vegetable intake.  Environmental factors as well as food intake can adverse or benefit the effects of dehydration……so drink up!

Although dehydration is a migraine trigger, it is avoidable with these tips and more diligent tracking.

    That water bottle looks cool but I’m sad to see it’s only for Apple devices. I hope they introduce Android soon. I know I don’t drink enough water and too much caffeine, it certainly isn’t helping my migraine. Do you have a post here that talks about how you log your migraines? You mention digital and paper but I’d love to know what app you recommend or what paper chart you use.

    I use migraine buddy when I’m doing it digitally. It is good except I get migraine spikes and need to log it as separate migraines in a day. I’m in a constant state of migraine but my pain level changes.

    I use Ulla smart hydration reminder on my water bottle. It blinks at me when I haven’t taken a drink in about 30 mins.

    That’s nice!! I wish mine had a reminder like that.
