When your skin gets dehydrated it causes dryness and wrinkling. This is different compared to dry skin though. Dry skin is lacking oil while dehydrated skin is lacking water. Water keeps your cells working at their best while a moisturizer will keep your skin hydrated and healthy.
Water is so crucial because so much of your body depends on it. Your body is anywhere from 50-70% water. All that water helps sustain cell health, helps with the elimination of toxins and waste, helps regulate body temperature, and helps with digestion. Because of all the different body parts that need water, it is recommended that you drink 9-12 cups a day.
75 % of Americans are dehydrated. That's 75 out of every 100 people that don't get enough water to help their bodies function to the best of its ability. Did you know that your metabolism will slow as much as 3% if you're just mildly dehydrated? How about that water can stop hunger pains for people on a diet? Did you know that the number one cause of day time fatigue is lack of water? Or that with a drop in body water as little as 2% it can trigger fuzzy short term memory, trouble with basic math, and difficulty focusing on a computer screen or printed page?
Now with all this information about water it'll motivate you to choose a little more water and a little less of other things. The benefits of water are endless.
