With our brains being 80% water, it's no surprise that when our bodies lack enough water, our heads begin to ache. "Why is this?" you ask? Well, when we don't feed our brain

enough water, it shrinks and causes pain around the brain. Also, dehydration=reduced blood flow and oxygen to the brain, which in turn leads to dilated blood vessels in the brain

that increase swelling and inflammation. So, next time your head begins to hurt, ask yourself when the last time you drank water was before reaching for the ibuprofen.

Sweating is an important part of a hard workout. When we're doing an intense workout, our bodies overheat, and sweating occurs to regulate our body temperatures. Without this temperature regulation, we're

subject to overheat or suffer from heatstroke. This is one of the many reasons why it's super important to have plenty of water at the ready during your workouts.

If you've been sleeping plenty and are generally healthy, but still find your energy levels slumping majorly throughout the day, you might be dehydrated. Without enough fluids, the body stores

up energy by decreasing blood circulation. Without proper blood flow, our oxygen is not being delivered to our muscles adequately, which then causes lethargy.

Drinking enough fluids is essential to the health and vibrancy of our skin. Without enough fluids, the skin is much more vulnerable to fine lines, cracking, and chapping. Also, a lack

of hydration could cause your tear ducts to dry up, and your mouth to have that cottony, ever-dry feeling. Drink up!

Not drinking enough water can cause an electrolyte imbalance in the body, and when those are off, your physical balance gets wobbly too! Also, watch out for if you're having trouble

concentrating, feeling a little delirious, or experiencing confusion, as those can also signal that your body's craving electrolytes.
