With a never-ending to-do list, it can be easy to overlook a few essential things. As a matter of fact, perhaps you haven’t been feeling your best lately. But before jumping to conclusions, ask yourself this simple question: How is your daily water intake?

Here are the classic, tell-tale signs that you need to drink up, big time.

1. Your skin is dry and itchy

Even though you moisturize after every shower, your skin feels dry and rough. Yikes! Truth is, not even the most powerful lotion on the market will leave your skin supple if you aren’t drinking enough water.

When dehydrated, the body pulls water from other areas to carry on with important processes. As a result, your skin is the first to suffer. If you’re after a radiant, super-soft-to-the-touch complexion make sure to keep a water bottle nearby. It’s the easiest – and cheapest – beauty trick ever.

2. Headaches…ouch!

You’re not exactly sure why but you’ve been experiencing nagging headaches lately. Before popping some painkillers, try reaching for a big ol’ glass of water first. As our brains are composed of 80% water, the liquid is vital for our well-being.

When dehydrated, blood flow and oxygen to the brain is reduced. This leads to dilated blood vessels and the result is swelling and inflammation. While a persistent headache should be checked out by a doctor, it can be worth upping your liquid intake to see if it helps.

3. You can’t stop snacking

Lunch was only an hour ago and you’re already planning a snack. While eating something light in between meals can help your energy level remain stable, too much of a good thing can also mean trouble. Step away from the cookie jar and grab a nice, cold glass of water instead.

The hypothalamus, the brain part responsible for our nervous and endocrine systems, can actually confuse thirst with hunger. If you need a bit of flavor, try adding berries to your water bottle for a refreshing snack with zero calories. Win!

4. Your urine is way too dark

The easiest way to tell if you’re dehydrated is by observing your urine’s color. If it’s dark and too concentrated, it’s likely that it has too much waste. Guzzle away and help your kidneys flush away those nasty toxins.

Not sure what to look for? Aim for a transparent or light yellow hue every time to you go to the restroom. This will guarantee your hydration level is in check.

5. You are feeling tired and lethargic

Just like food and sleep are essential for our energy levels, so is water. Instead of reaching for another double dose espresso to fight off that mid-afternoon fog, hit the water fountain instead, my friend.

When dehydrated, the body reduces blood circulation in an attempt to save energy. As a result, less oxygen is delivered to our muscles. The result is lethargy and counting- -down-the-minutes-for-bed-time mood. Help yourself become much more productive by drinking more water.

Remember: when you feel thirsty, you’re already dehydrated. Carrying a water bottle with you is the easiest way to stay on track. And when it comes to snacking, pick water-rich fruits such as watermelon, melons, and pears for a little hydration boost. As always, stay tuned for more health tips from OurStyleBlog editors.
