Preventing Body Odor

Have you ever finished a sweaty workout, and within minutes, noticed a peculiar smell? When "Jack" (not his real name) left the gym after basketball practice, he walked up to a group of friends. They immediately commented on someone’s body odor, wondering which of them was the culprit.

"When I realized it was me, I was humiliated," Jack said. "I quickly went to my locker and realized that I didn’t have a deodorant at school.

"I avoided all my friends that day. When I got home, I put my new deodorant in my backpack to make sure this never happens again."

Is Body Odor Normal?

Jack is not the first (or last) teen to notice body odor. Bromhidrosis (another word for body odor) happens at puberty because of increasing hormones called androgens. These hormones are not active until puberty, which is why body odor wasn’t a problem when you were a kid.

While sweat itself is virtually odorless, bacteria use it as a breeding ground and multiply rapidly. What you smell is the products related to bacteria breakdown of keratin protein on the surface of your skin. Sounds disgusting, doesn’t it? Chalk it up to an unpleasant fact of life!

When you work out or move around in the heat or sun, your body produces sweat. Sweating is the body’s way of regulating temperature. When sweat meets the bacteria on the surface of your skin, it produces an odor. That smell is what we call body odor (or B.O. for short).

Why Do My Feet Smell?

While body odor is usually associated with the armpits, bacteria can also produce odor in the groin, anus area, upper thighs, and feet, among other places. Thoroughly washing your skin with a wet washcloth and soap -- especially those areas prone to sweating -- can help prevent body odor.


How Do I Fight Body Odor?

If you want to be "odor-free" consider the following tips:

  1. Apply an antiperspirant at bedtime. This gives the product a chance to work while you sleep and are not sweating.  If you apply antiperspirants after showering in the moning, the sweat you accumulate will wash away the product and render you defenseless against daytime sweating. Remember, deodorants do not prevent sweating. They mainly mask the smell of the sweat on your skin. Antiperspirants are chemical agents that reduce sweating. Many antiperspirant preparations also contain a deodorant, which helps to mask the smell. Check the product you use to make sure it contains an antiperspirant.
