• Each resident in Phoenix produces 26.4 ounces of sweat an hour -- enough to fill two cans of soda.

• Living up to its nickname, the Sunshine State has four cities appearing in the top 10, more than any other state. Collectively, they produce enough sweat to fill Shamu's tank in 9.9 hours. (That's 6.5 million gallons)

• San Francisco is the nation's least sweaty city included on the list, coming in at number 100. Yet even with an average temperature of just 63.5 degrees during the summer months, each San Franciscan can still produce over 17 ounces of sweat per hour.
