MSNBC.com put out a list of the cities in America with the worst BO. Here are the 7 stinkiest cities in the country:

7. Yuma, Arizona

Serious sweating in the summer, plus lots of dead, dry skin, thanks to desert conditions. That makes Yuma a paradise for the bacteria on the skin that causes body odor.

6. San Antonio, Texas

This city is blazing-hot in the summer months and its citizens are in the top ranks of smokers.

5. New Orleans, Louisiana

It’s a very sweaty city, with high temperatures and humidity year-round. And it’s a smoker’s paradise. The state tax on cigarettes is low and the public smoking ban doesn’t extend to bars. About 20 percent of adults in this city smoke.

4. Chicago, Illinois

Stress sweat is the smelliest kind and Chicago is the number one most stressed out city in the US. There’s also a high percentage of smokers with about 1 in 5 Chicagoans lighting up.

3. Phoenix, Arizona

With a 105 degree average temp in the summer, it’s the sweatiest city in America, according to the Old Spice Top 20 All-Time Sweatiest Cities. The dry, desert climate also means lots of parched, dead skin.

2. Houston, Texas

Houston has one of the hottest summer temperature averages and chart-topping, year-round humidity.

1. Las Vegas, Nevada

A scorching, dry summer heat makes it one of the sweatiest cities in the US. A quarter of people in Sin City are pack-a-day smokers and that doesn’t help.
