Iced Tea is indeed one of the more purchased drinks in the country. According to the Tea Association of the U.S., tea stands alongside water as the highest consumed drink in 2016-17. In fact, whether it's hot or cold, tea can be found in nearly 80 percent of households across the country.

"The U.S. is the third largest importer of tea in the world, after Russia and Pakistan and the only western country to grow in tea imports and consumption," according to the Tea Association. "Approximately four in five consumers drink tea, with Millennials being the most likely."

Around the time of World War I, the National Iced Tea Day website notes that many Americans bought tall drinking glasses — which eventually were referred to as iced tea glasses — and long stirring spoons to use alongside it. Surprisingly, the Prohibition Era is what launched an increase in sales for the now popular hot-weather drink.

For those that enjoy a heavy dosage of the summer drink, they can feel comfort in knowing that this calorie-free beverage contains no sodium, sugar, fat, or carbonation. Essentially, iced tea is a fairly healthy thing to consume as it helps with overall fluid balance and it may be good for one's overall health as well, according to NITD's official website.

Several big-name retailers are participating in the nationwide holiday by giving out free iced tea to loyal customers.
