Dehydration can sneak up quickly, especially in hot weather or during illness. Three key signs to watch for are: dark yellow urine (a sign your body needs more fluids), dry mouth or lips, and feeling lightheaded or dizzy, especially when standing up. Other symptoms may include fatigue, headaches, or decreased sweating. Don’t wait until you feel thirsty, stay ahead by drinking water regularly throughout the day, especially during exercise or heat exposure.
