  • How much water do you really need? You should aim to drink around 9 cups a day to stay fully hydrated. I know it sounds like a lot, but if you have a glass when you wake up, another before bed, and a cup with every meal, you’re already halfway there! How do you get the rest? Chow down on veggies like lettuce, tomatoes, and cucumbers – not only are they chock full of nutrients, they’re also 90 percent water! And sneak in an extra glass or two if you’re exercising.

  • What’s the shelf life of bottled water? If bottled water is stored properly, it should last forever. What’s the best way to store it? Keep it in a dry place that’s out of direct sunlight.

  • Does mineral water give you any health benefits? The answer is YES. Most mineral water contains calcium, which helps keep your bones strong. In fact, some mineral water brands pack the same amount of calcium as a glass of milk!

  • Does drinking water make your skin look better? The answer is yes – and no. When your skin cells are hydrated, your skin does look younger. But as you get older, your cells begin to deteriorate, which makes it hard for them to hold on to the water you drink. What’s the fix? Eat a diet packed with eggs, spinach and soy – these foods contain a chemical that helps your body repair the damage so your cells can lock in more water. So although water does make your skin look younger, you also need to eat the right foods so your skin can hang onto the water you drink.
