We all know the importance of hydrating our curls, but what about your bodies?

When You DO Need More Agua

Although you may be rethinking those constant trips to the water cooler with your BPA-free reusable bottle, rest assured, there are times you need to increase your intake.

If you live in a hot, dry climate, are visiting a higher altitude than you’re used to or exercising outside in hot temperatures, you’ll need to get more than the recommended amount of water in your system, says Kristin Kirkpatrick, MS, RD, wellness manager for the Cleveland Clinic's Lifestyle 180 Program and YouBeauty Nutrition Advisor.

Also, the pressurized air in an airplane cabin consists of only 5 to 10 percent humidity (which can cause dry mouth and a scratchy throat) so you should always accept a non-alcoholic offer from the drink cart to replenish your fluids, says Ayoob. Your best options are water, any clear soft drink (they typically don’t contain caffeine) or club soda with a little cranberry juice.

Kirkpatrick points out that you don’t know how often the cart will come around, and those dinky little cups don’t hold enough water to replenish your fluids, so her airplane strategy is this: “The minute you get past security, buy an enormous bottle of water. Bring it onboard with you and take a sip every 15 to 20 minutes.”

Bottom line:

Water is an amazing substance and it’s seriously everywhere—in our bodies, beverages and foods. Just follow your thirst mechanism (don’t stress about forcing down pints of plain water each day!) and up your water-rich food intake for optimal beauty and health.
