Science has shown that the whole 8, 8oz of water idea is way off!!! Our bodies are different sizes, so that guideline hasn't apply for everyone. The rule is: calculate your exact weight. Take your weight and divide that number by 2. That number is the total number of ounces, minimally, you are required to drink daily. If you drink ANY beverage besides water, you must drink more water. For example, if you consume a 16oz glass of iced tea or coffee, you should drink 16oz more water. Now, I know you may be thinking, wow, that's a lot. Wait, look at your body, it's 75-90% water, you have to maintain a healthy system that functions correctly. Tell me what you think below. Until next time, ciao.
