Does Soaking Feet in Hot Water Help Smell?

Good hygiene habits like washing your feet daily are important, some claim that soaking your feet in hot water is an easy and effective way to help reduce foot odor. But does this old home remedy really work? Let’s take a closer look.

How Hot Water Helps

Hot water helps fight foot odor in a few key ways. First, the heat helps open up pores and loosen dirt, sweat, and dead skin cells. This allows the grime to be more easily washed away. The heat also expands blood vessels, increasing blood flow and circulation to the feet. Better circulation can help reduce excessive sweating, which means less moisture for bacteria to feed on.

Additionally, the hot temperature kills bacteria and fungi that cause odors. Studies show that prolonged exposure to temperatures over 110°F can eliminate microbes like Escherichia coli and Staphylococcus aureus that live on the skin and contribute to foot smell. Soaking for 15-20 minutes allows time for the heat to work its germ-busting magic.

Simply rinsing your feet in hot water during a shower is not enough. Soaking your feet allows time for pores to open up and circulation to improve so sweat and dead cells can be removed. It also gives heat long enough exposure to kill microbes lurking between toes and under calluses.

Adding Other Ingredients

For maximum odor-fighting power, you can add baking soda, vinegar, essential oils, or soap to your foot soak.

Baking soda balances pH levels on the skin, creating an environment less friendly to odor-causing bacteria. Its mild abrasive properties also help scrub away dead cells. Add 1⁄4 cup of baking soda to a basin of hot water and soak for 15 minutes.

Vinegar has antimicrobial properties that kill fungi and bacteria. White vinegar is typically used for foot soaks. Mix 1 part vinegar with 2 parts hot water and soak for 15 minutes. The vinegar smell dissipates as feet dry.

Eucalyptus, peppermint, and tea tree essential oils have cleansing, antibacterial, and antifungal properties to neutralize odors. Add 5-10 drops of your chosen oil to a basin of hot water and soak feet for 15-20 minutes. The oils also leave feet smelling fresh.

Antibacterial soap can eliminate bacteria when combined with hot water. Use a mild soap and avoid getting suds directly in the water. Rinse feet thoroughly after soaking to remove all soap residue.

Best Practices for Foot Soaks

To get the most out of a hot foot bath, follow these tips:

  • Use a basin big enough to accommodate both feet without crowding. Add hot water to cover feet up to the ankles.
  • Check water temp before soaking. It should be hot, but not so hot as to scald. 110-120°F is ideal.
  • Soak feet for 15-20 minutes to allow heat and ingredients to fully work.
  • Rinse feet with clean water and dry thoroughly, especially between toes where moisture gets trapped.
  • Exfoliate dead skin cells using a pumice stone or foot scrub. This allows odor treatments to penetrate deeper.
  • Apply foot powder or deodorant after soaking to help keep feet dry and discourage bacterial growth.
  • Soak feet 1-2 times per week for maintenance. Increase frequency if odor is particularly stubborn.
  • See a podiatrist if foot smell persists despite good hygiene and soaking. You may need treatment for hyperhidrosis (excessive sweating) or fungal infections.

A relaxing foot soak using hot water and natural antibacterial ingredients can help reduce foot odor by killing bacteria, softening skin, improving circulation, and controlling sweat. It combines the germ-fighting power of heat therapy with the cleaning and deodorizing properties of baking soda, vinegar, essential oils, and soap. For best results, be sure to fully dry and exfoliate feet after soaking. While not a cure-all, routine hot water foot baths can be an easy, spa-like way to keep your feet fresh.
