How To Get Rid of Underarm Odor Naturally: Home Remedies & Prevention

What Causes Underarm Odor?

Underarm (axillary) odor is primarily caused by the interaction of sweat with bacteria on the skin. While sweat itself is mostly odorless, the bacteria that thrive in warm, moist environments—like your armpits—break down proteins and lipids in sweat, producing unpleasant smells. Several factors can influence the intensity of underarm odor, including genetics, hormones, diet, stress, hygiene, and even the type of clothing you wear.

Why Choose Natural Remedies?

Many conventional deodorants and antiperspirants contain aluminum, parabens, and artificial fragrances that may irritate sensitive skin or have other health concerns. Natural remedies use everyday kitchen ingredients to neutralize bacteria, absorb moisture, and balance skin pH—offering a gentle, chemical-free alternative to commercial products.

Effective Home Remedies for Underarm Odor

Here are some of the most effective, easy-to-use natural treatments for underarm odor:

Baking Soda

Baking soda is a natural deodorizer that helps balance skin pH and absorb moisture. To use, mix a small amount with water to form a paste, apply to your underarms, let it dry, and rinse off. For a dry powder alternative, mix equal parts baking soda and cornstarch, then dust lightly on clean, dry underarms. Always do a patch test first, as baking soda can irritate sensitive skin.

Apple Cider Vinegar

Apple cider vinegar (ACV) is antimicrobial and helps restore the skin’s natural acidity. Dilute a few drops in water, apply with a cotton pad, and leave for a few minutes before rinsing. Repeat twice daily for best results.

Lemon Juice

Lemon juice contains citric acid, which lowers skin pH and makes it harder for odor-causing bacteria to thrive. Apply freshly squeezed lemon juice (diluted for sensitive skin) to your underarms for a few minutes, then rinse. Do not use lemon juice on freshly shaved or broken skin, as it can cause irritation.

Coconut Oil

Rich in lauric acid, coconut oil has natural antibacterial properties. Rub a small amount onto your underarms and let it absorb before dressing. It also helps soothe irritated skin.

Tea Tree Oil

Tea tree oil is a powerful antimicrobial agent. Mix a few drops with a carrier oil (like coconut or olive oil) and apply to your underarms. Always dilute tea tree oil to avoid skin irritation.

Turmeric

Turmeric’s active compound, curcumin, has antibacterial and anti-inflammatory properties. Make a paste with turmeric powder and water, apply to underarms, let it dry, then rinse off.

Witch Hazel

Witch hazel acts as a natural astringent, tightening pores and reducing sweat production. Apply with a cotton ball after showering for best results.

Lifestyle and Prevention Tips

In addition to topical remedies, certain lifestyle changes can significantly reduce underarm odor:

Maintain Good Hygiene

Shower daily and wash your underarms with antibacterial soap. This reduces bacteria on the skin, minimizing odor. After sweating, change into clean clothes to prevent bacterial growth.

Choose Breathable Fabrics

Wear loose, natural fabrics like cotton or moisture-wicking materials to allow your skin to breathe and reduce sweat accumulation.

Diet Adjustments

Certain foods (onions, garlic, spicy dishes, and red meat) can increase body odor by affecting sweat composition. Eating a balanced diet rich in fruits, vegetables, and water can help.

Manage Stress

Stress triggers the release of cortisol, which can increase sweat production and worsen odor. Practice relaxation techniques like yoga, meditation, or deep breathing.

Topical Products and Deodorant Alternatives

If you prefer not to make your own remedies, several natural deodorants and powders are available commercially. Look for products with ingredients like arrowroot powder, baking soda, essential oils, and magnesium hydroxide.

Understanding Excessive Sweating (Hyperhidrosis)

Some people sweat more than usual due to a condition called hyperhidrosis. If excessive sweating significantly impacts your daily life, consult a healthcare provider. Treatments may include prescription antiperspirants, oral medications, Botox injections, or even surgical options.

When to See a Doctor

Occasionally, persistent or sudden changes in body odor may signal an underlying medical condition, such as diabetes, thyroid problems, or liver/kidney disease. If home remedies and lifestyle changes do not help, or if you notice other symptoms, seek medical advice.

Common Myths About Underarm Odor

• Sweat itself smells bad: Sweat is mostly water and salts; odor comes from bacteria breaking it down.
• Shaving eliminates odor: Shaving can reduce bacteria by removing hair, but it does not eliminate odor entirely.
• Natural remedies don’t work: Many natural ingredients have proven antimicrobial and odor-neutralizing properties.
• Only teenagers get body odor: While puberty increases sweat gland activity, people of all ages can experience underarm odor.
