 For NPR News in the Twin Cities, I'm Mike Moen. With temperatures soaring into the upper 80s today in the Twin Cities and upper 90s in southwest Minnesota, it's important to stay hydrated to keep your body safe. Experts recommend men drink 13 cups of water daily, women should drink at least 9 cups of water, and children should get 6 to 8 cups. That's according to Katie Loth, a dietician with the University of Minnesota Medical School.
