Sweat Side Effect #1: Eases Pain
Got a kink in your neck that won't quit (and no one around to massage it out)? Working up a sweat just might soothe the soreness, experts say. "Exercise stimulates neurochemical pathways in the brain, resulting in the production of endorphins that act as natural painkillers," says James Ting, M.D., a sports medicine physician at Hoag Orthopedic Institute in Irvine, CA.

Sweat Side Effect #2: Blasts Zits
"When you sweat, your pores open and release the grit and grime that has built up inside of them," says Whitney Bowe, M.D., a dermatologist in Briarcliff Manor, NY. Caveat: Don't just sweat and go. All of that dirt from your pores accumulates on the surface of your skin, so aim to wash your face three times a day, especially if you are constantly playing sports or working out.

Sweat Side Effect #3: Rids the Body of Toxins
Not feeling the whole post-weekend juice detox plan? Hit the mat for a super-sweat session instead. Some experts believe that sweating can flush the body of system-clogging substances like alcohol, cholesterol and salt. Get the most bang for your bod with indoor cycling or circuit training -- two of the sweatiest workouts, according to Melissa Morin, an exercise physiologist and Senior Director of Group Exercise at New York Sports Club.

Sweat Side Effect #4: Controls Mood Swings
Maybe you've already noticed -- before a workout you're Ms. Crabby Pants. But afterwards you feel like giving everyone hugs and high fives. It seems natural that we associate feeling warm with a sense of well-being and relaxation, but there may in fact be a scientific explanation for this feeling, says Dr. Ting. "Research has suggested that temperature-sensitive neural circuits to specific regions in the brain exist and may play a significant role in controlling mood." So the next time you sense yourself being short, take a break for a Bikram yoga session or a run for a get-happy fix.

Sweat Side Effect #5: Prevents Colds and Other Infections
If you've ever wished you could walk around dousing everything in sanitizer wipes to prevent illness, you might be in luck. A study from Eberhard-Karls-University T?bingen in Germany suggests that human perspiration contains a naturally occurring antimicrobial peptide called dermcidin, which has been proven to fight tuberculosis germs and other dangerous pathogens, says Dr. Bowe. It's like an invisible germ force field!

Sweat Side Effect #6: Regulates Body Temperature
The evaporation of sweat off of the skin prevents us from overheating during an intense workout, says Dr. Bowe. So, what would happen if you didn't sweat? "In extreme cases, the lack of sweat during a seemingly strenuous workout could be due to a condition called anhidrosis that can lead to dizziness, a skin rash, or loss of consciousness during exercise," says Morin.

Sweat Side Effect #7: Lowers Kidney Stone Risk
Yes, really! Research from the University of Washington found that regular exercisers sweat out salt and tend to retain calcium in their bones, rather than having them -- salt and calcium -- go into the kidneys and urine where stones form. Frequent sweaters also tend to drink more water and fluids, which is another stone prevention mechanism.
