Here are 5 solid ways to stop body odor naturally by addressing the root causes: bacteria, moisture, and diet.
1. Use Natural Acids (Like Apple Cider Vinegar)
Body odor is caused by bacteria breaking down your sweat, not by the sweat itself. To stop the smell, you need to change the pH of your skin. Bacteria thrive in a neutral or alkaline environment but cannot survive in acidic conditions.
• How to do it: Dip a cotton ball into raw, unfiltered apple cider vinegar and wipe it onto your underarms or feet. Let it dry. The strong vinegar smell evaporates completely within minutes, leaving you odor-free.
• Why it works: It acidifies the skin, creating a hostile environment for odor-causing bacteria. It is a natural deodorant, not an antiperspirant (it won't stop you from sweating).
2. Fight Bacteria with Probiotics
Odor starts in the gut and on the skin. By balancing your internal microbiome, you can change the composition of your sweat and crowd out the "bad" bacteria that create smell.
• How to do it internally: Eat fermented foods like kimchi, kefir, plain yogurt, or kombucha daily. You can also take a high-quality probiotic supplement.
• How to do it externally: Open a capsule of a probiotic (or plain yogurt) and mix it with a little water to make a paste. Apply it to your underarms and leave it for 5–10 minutes before rinsing.
• Why it works: Beneficial bacteria can outcompete the smelly bacteria on your skin. Internally, they help your body process foods that might otherwise cause foul-smelling sweat.
3. Target "Odor Fuels" in Your Diet
What you eat directly determines what you excrete through your pores. Certain foods contain sulfur compounds and other volatile molecules that seep out through your skin, making your sweat smell pungent.
• What to reduce:
• Red meat: It takes longer to digest and can leave residue in the intestines, which interacts with gut bacteria to produce foul-smelling compounds.
• Cruciferous vegetables: Broccoli, cauliflower, and cabbage are healthy, but they are high in sulfur, which can smell like rotten eggs when secreted in sweat.
• Alcohol and spicy foods: These increase body temperature and cause you to sweat out the metabolites of the substances.
•What to increase:
· Chlorophyll-rich foods: Parsley, cilantro, wheatgrass, and spinach act as natural internal deodorizers. Chlorophyll is known to neutralize odors in the body.
· Drink plenty of water: This dilutes the concentration of odor-causing compounds in your sweat.
4. Use a Sugar Scrub to Remove Buildup
Deodorants and antiperspirants (especially aluminum-based ones) can build up a layer of residue and bacteria on your skin. Regular soap doesn't always remove this "biofilm." This buildup traps bacteria and mixes with new sweat, creating a stubborn smell that returns immediately after showering.
• How to do it: Mix 1 tablespoon of coconut oil with 1 tablespoon of fine sugar. Scrub your underarms vigorously for 1–2 minutes in the shower. Rinse well.
• Why it works: This physically exfoliates the dead skin cells and trapped bacteria that soap can't dissolve. Coconut oil contains lauric acid, which is also antimicrobial. Doing this once a week resets your underarms so natural deodorants work better.
5. Wear Breathable Fabrics (Especially Wool)
Synthetic fabrics like polyester and nylon are hydrophobic (they repel water). They trap heat and moisture against your skin, creating a breeding ground for bacteria. They also tend to develop a permanent odor over time because the oils and bacteria get stuck in the plastic fibers.
• How to do it: Switch to merino wool, cotton, or linen.
• Why it works:
· Merino wool is the gold standard. It can absorb 30% of its weight in moisture without feeling wet, and it actively traps odor molecules until you wash the garment. You can often wear wool shirts multiple times before they smell.
· Cotton and linen allow air to circulate, allowing sweat to evaporate quickly so bacteria doesn't get a chance to multiply and break the sweat down into smelly acids.
A note on hygiene: While natural remedies work, remember that bacteria love moisture. Showering twice a day during hot months and drying yourself completely (especially between toes and under arms) before getting dressed is the foundation of any odor-control routine.
