EMSA is urging citizens to take proactive measures to stay safe in the heat by keeping fluids accessible and drinking plenty of water before going outdoors and during outdoor time. Also, limit outdoor time and take frequent breaks in shade or indoors, especially if having extended time outdoors such as sporting events and yardwork.
 
Tips for staying healthy in the heat include pre-hydrating, which is key in preventing heat-related illness, drink plenty of water or electrolyte replacement drinks several hours prior to and during long exposure to the summer heat, wear light-colored, loose-fitting clothing and a wide brimmed hat if working outdoors and take plenty of shade breaks, no alcohol or caffeine and if you do not have air conditioning, find a cooling station or public space (such as libraries or malls) during the day.
