Most people think that antiperspirants and deodorants are the same thing, but they aren’t. Antiperspirants work by clogging, closing, or blocking the pores with powerful astringents such as aluminum salts so that they can’t release sweat. (Note that aluminum can accumulate in the brain.) Deodorants work by neutralizing the smell of the sweat and by antiseptic action against bacteria. Deodorants are preferable because they don’t interfere with sweating, a natural cooling process.

Baking soda works wonders because it neutralizes the odor of sweat. Just sprinkle a light covering of baking soda onto a damp washcloth. Pat on. Don’t rinse.

This tip—just using baking soda—has saved me on many occasion, especially when traveling.
