4. Acts as a Deodorant

With excellent odor-absorbing power, baking soda appears in many deodorants—one reason people keep an open box in bathrooms or freezers. Its effectiveness comes from antibacterial properties. Sweat itself is odorless; bacteria break it down into acidic byproducts that smell. While baking soda does not stop that process entirely, it makes the result less acidic and far less smelly. In a pinch, pat some under your arms as a natural deodorant.
