Time - Most adults should drink somewhere between 68 and 100 ounces of water each day, says Dr. Ashley Karpinos, associate professor of medicine, pediatrics, and sports medicine at Vanderbilt University Medical Center. Another way to keep track of your water intake is to halve your weight in pounds—then drink that number of ounces each day, says Dr. Dana Cohen, an integrative medicine practitioner in New York City and co-author of Quench, a book about the science behind hydration. But “in the heat, everyone needs more water,” Karpinos says. If you’re working, exercising, or are otherwise active in hot weather, a good rule of thumb is to drink eight ounces of water every 15 to 20 minutes during the physical parts of your day, Karpinos says.
