The sun's heat can cause heat-related illnesses. Stay cool by staying hydrated.
"Drinking enough water in the summer months is the best way to prevent dehydration," said Myers. "Adults should try to drink six to eight 8-ounce cups of water every day. On a hot summer day, you should try to drink fluids every 15 to 20 minutes."
According to the U.S. Centers for Disease Control and Prevention, dehydration can cause unclear thinking, mood swings, overheating, constipation, and kidney stones.
"It is also important to be aware of your medications," added Myers. "Some antibiotics, allergy medications, beta-blockers, seizure medications, diuretics, laxatives, some diet pills, and ADD medications could actually put you at more risk for heat-related illness."
