SAVANNAH, Ga. (WTOC) - As temperatures climb across the Coastal Empire and Lowcountry, doctors are emphasizing the importance of staying hydrated, especially during outdoor activities. St. Joseph’s Candler Hospital Emergency Physician Dr. Jim Gill said preparation is key before heading outside, especially for those planning to exercise. “Your body always needs water even when it’s not hot, but it needs extra, especially at this time of year,” Gill said.
