The average Phoenix, AZ resident will crank out 26.3 ounces of sweat per hour this summer, making it the sweatiest city in the U.S., according to Procter & Gamble.

Collectively, the city's population sweats enough to fill more than 53,000 beer kegs in just one hour.

P&G ranks cities by sweat for its Old Spice brand, the No.1 selling antiperspirant/deodorant stick and body wash brand among men of all ages.

After Phoenix, the nine sweatiest cities are Las Vegas, NV; Dallas, TX; Tucson, AZ ; San Antonio, TX; Waco, TX; Shreveport, LA; Austin, TX; Oklahoma City, OK, and Corpus Christi, TX.

And the least sweatiest? San Francisco, Seattle, and Portland, Maine.
