Your body is about 60% water.
Water represents a critical nutrient whose absence will be lethal within days. Water’s importance for the prevention of nutrition-related non-communicable diseases is a scientific fact. But how much? I’m sure you’ve felt some of the effects of your cells being dehydrated, including headaches, feeling foggy, constipation, and feeling sluggish physically and mentally. How much water you need to stay healthy is affected by your health, activity, and environment. Drinking at least half your body weight in ounces is a good star and as a bonus can help with weight loss and increased metabolism.
