Water is essential to every major process and function in the body — from circulation to digestion — so it’s important to keep it replenished. While refueling needs may vary, here are a few common recommendations:
Drink 8 8-ounce glasses of water a day. This is good advice for most of us, most of the time. But no single formula fits all. Men, athletes, or those who live or work in hotter climates may require more. Drink enough so your urine is pale yellow.
Limit caffeinated beverages. Try to keep caffeine intake to 200-300 mg per day (about 2-3 cups).
Drink water before, during, and after exercise. Nutritionists recommend 4-6 ounces of water for every 15-20 minutes of exercise.
Consume fluids during or immediately after a meal. Liquids help break down food and keep the digestive process moving along. So eat, drink, and be merry.
