What You Need to Know About Body Odor

Noticing a friend’s B.O.? Try one of these conversation starters to let them know they need to switch up their routine—without hurting their feelings. Make sure to save the exchange for when you’re in private.

1. Share the blame: Sniff your own armpit and say, “Is that your B.O. or mine?” Then offer a fix: “I’m using a great new deodorant if you want a recommendation.”
2. Focus on the product, not the person: Let your friend know that their deodorant is a little weak, and encourage them to make a change.
3. Express concern: Ask your friend if everything is OK. Sometimes B.O. can indicate a lack of access to a shower or washing machine, or be a sign of depression.

Did you know that the fabrics you wear can affect your body’s odor? Here’s how:

Synthetic fabrics 

Like nylon, polyester, and rayon wick away sweat but attract oil, amplifying the smell of body odor. They’re a great choice for staying dry while working out, but you’ll want to take special care to shower and change after wearing them.

Natural fabrics 

Like cotton and linen absorb moisture if you get sweaty, but they don’t retain as much odor as synthetic materials. Wool is naturally wicking and odor resistant and can be washed less often.
