What are the effects that you can actually SEE in terms of beauty and outward appearance when your body isn’t hydrated? Skin that is dehydrated often looks sallow, worn, dry, and wrinkled. In order to keep skin’s collagen intact, you should make sure that you consume enough water.
How much water should you drink? One half of your body weight in ounces should be consumed every day. If you weight 200 pounds, you should drink around 100 ounces of water (3.13 quarts or about 10-12 cups of water a day). If you weigh closer to 100 pounds you will need only about 50 ounces of water or about four 12-ounce glasses daily. The best way to consume this much water is to keep a glass by your side at all times. If you are active, this amount should be increased.

If you aren’t sure whether or not your skin is dehydrated, try this simple test: get into the habit of drinking at least eight glasses of water per day. After one week, see whether or not your skin’s condition improves. Most people will find that their skin takes on a more rosy, youthful, healthy look.
