Plenty of people spend thousands on beauty products but forget one simple step that could keep them looking and feeling much younger: hydration. Water is easily one of the most powerful -- and neglected -- ways for you to look better, stay healthier, and keep your mind sharp.

Hydrate = Rejuvenate: Water's Beauty Benefits

Getting glowing skin can be easier than you think: proper water intake is one of the strongest ways you can prevent and reverse wrinkles and keep your skin soft, smooth, and firm. The secret: keep it constant.

Throughout the day, a portion of your water balance exits your body through your pores – leaving your skin thinner, rougher, and depleted of a key component it needs to keep itself healthy. Healthy water intake gives your skin the key it needs to unlock its own potential and keep itself smoother, firmer, and softer. Since hydration helps skin maintain its support structures, it can also noticeably minimize sagginess.

The best part? The body processes water quickly enough that upping your intake on a rough day could give your looks a super-subtle but effective boost in just under half an hour.

Water for Wellbeing: Good for the Body, Good for the Brain

Water is the original detox product and plays a central role in keeping every single body system clean and running properly – and that includes your mind. Without enough water, you lose some of the fluid cushioning your brain, leaving you less alert, focused, and responsive; less happy; and often dizzy, achy, weak, and nauseous as well.

You may be so used to these effects on a smaller scale that you've just stopped noticing, but be careful. Poor hydration habits over a long period of time can lead to hemorrhoids and even urinary tract infections, which if untreated can be fatal.

Tips to Get You Guzzling:

• Get hooked on a habit, not numbers. Instead of waiting until you get thirsty to chug your day's "8 glasses," make a habit of drinking a glass before, a glass during, and a glass between each meal.

• Notice the "highs." Pay attention to how you feel when you're hydrating properly, and you will start to notice how much better you feel. When you feel a lack of focus or the onset of mild malaise, make your first question, "am I low on water?" – at the least, taking a hydration break will give you a guilt-free breather from other stressors.

• Cut out competing addictions. Tea, coffee, and soda cause you to lose water, so trim them out of your diet or up your intake. Also hydrate about twice as much when you're sick or exercising, and always pay attention to the color of your urine. If it's brownish or even just a "strong" yellow, drink more water.

• Show some taste. If you have trouble drinking when you don't "feel thirsty," try enhancing water with calorie-free flavor packets, a few drops of lemon juice, or crushed fresh mint. Get creative.
