Being well-hydrated will improve your energy, memory, focus, mood and health. Our bodies are at least 70% water. We need lots of it for cellular function.
Many people mistake thirst for hunger, so drink water before you grab a snack. Guideline for water intake: take your weight in pounds, and drink half that in ounces. ( i.e. If you weigh 200 pounds, you need 100 ounces of water, daily.)
For every cup of coffee or carbonated beverage you drink, add two more cups of water. To prevent a hang-over, drink as much water as you can.
Avoid water bottled in plastic. Plastic molecules leak into the water, mimicking estrogen, causing a lot of problems with the endocrine system. Get a water filtration system for your home and carry your own water with you.
