If you’re fact-checking “I put baking soda on my feet and you won’t believe what happened,” the likely claim is that baking soda can eliminate odor, fungus, or other foot problems. Some uses are reasonable, but baking soda isn’t a cure-all.
What baking soda may actually do
- Reduce odor: Baking soda can absorb moisture and help neutralize odors, so using a small amount in dry footwear may help with foot odor.
- Reduce moisture somewhat: Keeping feet dry can make the environment less favorable for odor-causing microorganisms.
- It does not reliably cure athlete’s foot: Persistent itching, peeling, cracking, or a rash between the toes is better treated with an appropriate antifungal product or evaluated by a healthcare professional.
- It can irritate sensitive or cracked skin: Don’t apply it to open wounds, significantly irritated skin, or areas that are already painful.
A safer approach
Wash your feet regularly, dry carefully between the toes, change socks daily (more often if they become sweaty), and allow shoes to dry completely between uses.
Bottom line: Baking soda may help with foot odor, but dramatic claims that putting it on your feet will “detox” your body, cure fungus, or transform your health aren’t supported by good evidence.
