How Much Do You Sweat in an Hour?

During a "typical summer day" in Phoenix, AZ, where the average temperature is 93.3 degrees Fahrenheit, a person produces 26 ounces of sweat per hour. That's three cans of soda. In other words, in Phoenix, you will sweat a six pack every two hours during the summer.

I dug up these numbers in a Reuters report (by way of Yahoo! News) on a Procter & Gamble Co. survey for the country's sweatiest city.

Across the city, about every three hours, "Phoenix residents collectively produced enough sweat to fill an Olympic-sized swimming pool," said Jay Gooch, a "sweat expert" at Old Spice (a P&G brand).

So where does all that sweat go? Apparently, in Phoenix, where the humidity is a dusty 22 percent, the air soaks up a lot of the sweat. In a city like Miami, on the other hand, where the average temperature is 83.9 F and the average humidity is 76 percent, that sweat just sticks to your body and soaks your clothes.

Because of Miami's mix of heat and humidity, it was named the "most uncomfortable" city by the survey.
