The first sports drink was Gatorade, which was invented in 1965 by a team of researchers at the University of Florida, led by Dr. Robert Cade. The team created the drink to help the Florida Gators football team overcome the dehydration and electrolyte loss caused by intense exercise in the hot and humid Florida climate. The drink originally consisted of lemon juice, salt, glucose, and water, and has since become one of the most popular sports drinks in the world.
