In the heat of summer, getting enough water is key to preventing dehydration , which can sap your energy and even be life threatening. Check the label of flavored bottled water for added sweeteners, which increase calories. Sparkling water has a fizz and can be sweetened or plain. Mineral water contains naturally occuring minerals that add to its taste.
Spring water comes with or without fizz.
No matter what you choose, summertime is the right time to work on increasing your water intake to at least 8 to 12 cups each day.
