Wonderful Water


You need it to stay alive. In fact, without it, you couldn’t survive for more than about four days. More than half your body is made up of it. Fortunately, there’s plenty of it; almost three-fourths of the earth’s surface is covered in it. What is “it”? WATER!


Most experts agree that an average person needs between 64 and 80 fluid ounces of water every day to sustain normal body function. If you’re an active person, or if you spend a lot of time indoors in conditioned air, your body may require 100 or more ounces of water per day.


That seems like a lot, but any fluid that doesn’t contain caffeine counts toward that daily total. If you do drink a lot of caffeinated drinks like coffee, cola, or certain teas, you might consider a switch to decaf. Water is your best beverage choice, because it contains no calories, fat, or cholesterol, and very little sodium. Caffeine is a diuretic, a substance that causes your body to get rid of water. Alcohol also robs your body of water and nutrients.


If you plan on exercising, try to drink water before, during, and after your routine. Cool water helps lower body temperature after a workout.


Your body needs water to keep you feeling alert and energized. Water helps remove toxins and keeps joints lubricated, while also delivering nourishment to your cells. Good hydration makes your breath smell better, keeps hair healthy, and helps prevent wrinkles.


Dehydration can impair heart function and raise blood sugar levels. It can also cause your body to store water and burn body fat less efficiently. Without enough water, you may experience fatigue, dizziness, extreme thirst, or headache.


If you often feel thirsty, or if your mouth is frequently dry, chances are you’re already somewhat dehydrated. To avoid this, add water to your daily routine. Have a full glass with snacks or meals, or when taking medication. If you still aren’t drinking enough, add a nonalcoholic “happy hour” or decaffeinated tea time to your day.
