Dehydration
Feeling extra thirsty? Chances are you’re dehydrated from a day spent outdoors. The sun is known to deplete our bodies’ natural fluids, making it extra important to hydrate throughout the day. While water is always the No. 1 choice for natural hydration, juices, coconut water or sports drinks can also help replace electrolytes lost while sweating.
Lightheaded or dizzy
Feeling mildly lightheaded or dizzy after spending time in the sun could be due to a drop in blood pressure as your body diverts blood away from your brain and toward your skin in an effort to cool you down. Another possible culprit is dehydration. Doctors recommend sipping fluids and relaxing to combat this problem.
