1. Thirst

If you've ever heard the saying, "If you're thirsty, you're already dehydrated", there is actually a significant amount of truth to that. When there is a lack of fluid in our system (or too much sodium in our body), the amount of water volume that we need in order for our body to work correctly drops which makes us want to drink more. You can stay on top of this by drinking 2-3 cups of water per hour (that you're awake, of course). If you do that, you should avoid feeling thirsty or parched. And, when it comes to your body "flowing" smoothly, that's a good thing.

2. Fatigue

Word on the street is, when you're at the point of dehydration, you've already lost somewhere between 2-3 percent of your own body fluid. If that happens, it makes total sense that you would start to feel tired, drained, lethargic—fatigued. When there isn't enough fluid in your system, your blood volume drops and that keeps your brain from getting all of the blood (and oxygen) that it needs. Plus, dehydration makes your heart pump faster than it needs to as well. So yeah, if you want an energy pick-me-up, drinking more fluids is a surefire way to go.

3. A “Pop Off” Spirit

If you feel like you're about to snap on somebody, drink something first. A couple of glasses of water, if you can. While it might sound crazy on the surface, another bona fide indication of dehydration is you're in a bad mood. How do the two dots connect?

When your fluid levels are low, the neurons in your brain are able to easily detect that. As a result, they will signal to other parts of your brain what's up, including the area that regulates your moods. Hmph. Considering 75 percent of Americans are chronically dehydrated, it makes you wonder how many are irritable, short-tempered, and just plain mean, simply because they don't have as much fluid in their body as they should, huh?

4. Blurred Vision

Have you ever had moments when, while scrolling through your Instagram or trying to watch television, your eyes suddenly became blurry? Before you freak out, drink more. Our eyes need fluids in order to remain moist and comfortable. This means that when we are dehydrated and our body fluid levels drop, that can result in dry and irritated eyes. This is just one more reason why drinking more water is such a good idea.

5. Sugar Cravings

If you want to get a grasp of just how serious sugar addiction in this country is, check out Healthline's "America's Deadly Sugar Addiction Has Reached Epidemic Levels". But if you're typically not someone who is big on sugar and yet, you find yourself having moments when you can't seem to get enough of it, this could be another sign that you're dehydrated. Something that our organs need is a healthy amount of glucose. Well, when we don't have enough liquid in our body, that can make it difficult for organs like our liver to release glucose and provide our bodies with an energy boost. As a result, we might think that we need a sugar rush when really, all we need is to drink more. How crazy is that?

6. Unexplainable Breakouts

Whenever I get pimples that have nothing to do with my period, it's usually a heads-up for me that I need to drink more water. Something else that drinking more does is flush toxins out of our system and help to keep sebum from clogging up our pores. A lot of us are out here thinking that if we put everything under the sun on top of our zits that they'll go away. But the reality is if we drank more good ole' H20, we probably wouldn't have so many pimples to deal with in the first place.

7. Bad Breath

There is someone I went to high school with who had the worst breath ever. Well, she and a guy I went to college with actually ran neck and neck with this particular "award". In hindsight, something that I realize they had in common is I rarely, if ever, saw them drinking water. It was juice, soda—anything but. Here's the thing about that—when we don't get enough fluid into our system, that keeps us from producing the amount of saliva that we need in order to flush out oral bacteria.

When bacteria lingers, not only does that create a breeding ground for tooth decay, but it can make our breath smell pretty damn tart as well. Just one more reason to drink more; more specifically, drink more water. For your sake and the sake of those around you.

8. Constipation

Quiet as it's kept, one of the leading causes of constipation is dehydration. We eat our food, it goes into our colon and, if we don't have enough fluids in our body, our colon takes in the water from the food waste, making it harder for the waste to pass through us. Constipation can ultimately lead to everything from hemorrhoids (from straining to have a bowel movement) and stomach aches to a lack of appetite and bad breakouts. All of it sucks. Avoid this by getting at least 6-8 glasses of water in on a daily basis.

9. Muscle Cramps

Do you ever get random Charley horses in your leg? Aren't they the absolute worst, especially if they happen in the middle of the night? That used to happen to me until I got more water into my system. What I discovered is, that whenever I'm dehydrated, the lack of water (and sodium) that my muscles need can result in them tightening up in a way that oftentimes feels just like cramps. This is really important to keep in mind, especially if you work out (and sweat) a lot or you plan on spending a lot of time outdoors where you'll lose a fair amount of body fluid.

10. Dry Skin

As we age, something that we definitely need to do is get more fluids into our system. When we don't, our skin starts to lose elasticity that can lead to sagginess and wrinkles. Not to mention the fact that if our skin's pores don't get enough fluid, the natural sebum that we produce can decrease, resulting in our skin becoming mad parched and looking super dry. So, if you want your skin to be soft, supple and moist, you already know what I'm gonna say, right? Water will help to prevent your skin from looking and feeling parched which can keep you looking younger than ever for a longer than expected. Drink up, sis.
