The human body can only exist for 5-7 days without water, thus dehydration must be taken seriously. Just exactly what does dehydration mean? Medically, dehydration is a serious and potentially life-threatening condition in which the body contains an insufficient volume of water for normal functioning.
1 Drink Plenty of Water All the Time. To avoid dehydration, the average adult needs six to eight cups of water a day. If you're not drinking adequate amounts of water throughout the day, you'll already be dehydrated when it's time to start exercising. If you exercise while dehydrated, you'll suffer from more cramps. When you're dehydrated, your muscles aren't able to function as well as they should and you'll tire more easily. Try to drink 16 to 24 ounces of water about an hour before you work out.
