It's best to consume water throughout the day, whether you're thirsty or not. If you're outdoors in the heat or if you're exercising you'll need to drink even more. Eight glasses of water a day is just a guideline that should be adjusted depending on your activity level. If you aren't getting enough water, your body may have a difficult time regulating its internal temperature. You could have dry skin and feel tired.
Severe dehydration can lead to kidney and circulation problems.
