Most of us know that dehydration can lead to some pretty serious health consequences, but did you know that it can also cause some more subtle symptoms?

If you're not careful, dehydration can sneak up on you and leave you feeling fatigued, irritable, and just generally crummy.

Here are a few early signs of dehydration to watch out for so you can nip them in the bud before they get any worse.

You're Thirsty (Obviously)


This one seems like a no-brainer, but it's worth mentioning because it's often the first symptom people ignore when they're slightly dehydrated. If you're thirsty, that means your body is already low on fluids and you need to drink up!

You Have a Headache


Dehydration can cause headaches and migraines because it leads to lower blood volume and reduced blood flow to the brain.

If you're prone to headaches, make sure you're staying hydrated throughout the day—especially if you're working out or spending time in a hot environment.

Your Mouth Is Dry


Dehydration causes your mouth and throat tissues to lose moisture, which can leave you feeling parched. This is why it's important to drink water regularly throughout the day, even if you don't feel thirsty.

You're Dizzy or Lightheaded

Dehydration can cause your blood pressure to drop, which doesn't give your brain enough oxygen and can make you feel dizzy or lightheaded. If this happens, sit down or lie down and drink some water right away.

You Have Dark-Colored Urine


If your urine is dark yellow or brown, that's a sign that your body is trying to hold onto fluid instead of flushing it out. Drink up!

You Pee Less Than Usual

If you're urinating less frequently than normal or if your urine is clear or light yellow, that means you're well-hydrated.

On the other hand, if it's been a while since you've had to go or your urine is dark yellow, that's a sign of dehydration.

Conclusion


As you can see, there are a lot of different symptoms of dehydration—and they range from annoying to seriously concerning.

That's why it's so important to make sure you're drinking enough water every day!

To avoid becoming dehydrated, experts recommend drinking eight 8-ounce glasses of water per day—but more if you're active or live in a hot climate.

So next time you're feeling parched, don't wait—reach for a glass of H2O!
