The summer sun can pose some extremely uncomfortable and dangerous situations for people. Here are some tips to stay cool in the summer heat (reference):

-Drink lots of water, or sports drinks if you're going to be exercising more intensely. It's necessary to replace what your body sweats out.

-Wear lightweight clothing and take frequent breaks to prevent overheating.

-Don't wait until you're feeling dizzy to take a break. Waiting so long can have serious health risks, such as passing out and having seizures.

-Wear sunscreen (at least SPF 15), hats and sunglasses to avoid sunburn.

-Limit strenuous activities to the early morning and late evening, when the sun is less intense.
