Can Dehydration cause Headaches?

Dehydration Headaches

Can dehydration cause headaches? Yes! And for me, dehydration triggers my 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 sitting, at my desk and classroom) but realized I wasn’t drinking it.  This was a problem.  I have a couple of dehydration headache remedies and tips I use. This post contains dehydration headache remedies.

Dehydration Headache Remedies and Tips

Track Water Intake

hydration tips

I bought a Thermos Smart Lid water bottle to help track digitally. I track my migraine life both digitally and with paper/pencil. 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. This water bottle and app give me an accurate reading and I like it. 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 helps with my overall battle. Another option is to get a prelabeled bottle as a reminder. Motivational quotes and time reminders can help keep you on track.hydration tips

Use reminders

If your water bottle reminding you isn’t enough, set alarms on your phone to drink every few hours.

Hydration Tablets

dehydration remedies tips

When I think the heat is going to be an issue, I use hydration tablets on vacations and sweaty situations.  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 headaches?

Even mild dehydration can trigger migraine attacks.  I recently started using hydration tables on a normal basis. I use NUUN tables after my workouts to add electrolytes 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.” Although dehydration is a migraine trigger, it is avoidable with these tips and more diligent tracking.


  • Avoid caffeine
  • Avoid alcohol
  • Increase fruit and vegetable intake
  • Be aware of environmental factors
  • Monitor food intake
  • Find shade

    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.
