how to manage body odour naturally

Have you ever caught a whiff of something unpleasant and realised—with that sinking feeling—it might be coming from you? We've all been there. That moment in a crowded lift when you suddenly become aware of your post-gym aroma, or that awkward realisation that your feet are creating their own ecosystem inside your shoes.

Body odour is a universal human experience, yet we rarely talk about it openly. It's time we changed that. After all, understanding the science behind those smells is the first step toward managing them naturally.

What exactly is body odour?

Body odour isn't actually caused by sweat itself. Surprising, isn't it? Fresh sweat is virtually odourless. The distinctive smell develops when sweat meets the bacteria living on your skin—creating a perfect environment for those microscopic residents to break down proteins into compounds that, well, don't exactly smell like roses.

There are several types of body odour conditions that might be affecting your daily life:

  • Bromhidrosis: This occurs when overactive sweat glands produce excessive perspiration, creating more "food" for odour-causing bacteria.

  • Trimethylaminuria: Sometimes called "fish odour syndrome," this genetic condition prevents the body from breaking down trimethylamine, leading to a distinctive fishy smell released in sweat, urine, and breath.

  • Axillary osmidrosis: This specifically refers to underarm odour caused by bacterial buildup in the armpit region, where warm, moist conditions create an ideal bacterial breeding ground.

While some level of body odour is completely normal, persistent or sudden changes in your personal scent can sometimes signal something more significant going on with your health.

Why your body develops odour

Remember that teenage phase when your body seemed to have a mind of its own? There's a reason body odour typically kicks in during puberty. As our bodies begin producing more androgens (the hormones responsible for reproductive development), our sweat glands—particularly the apocrine glands—become more active.

Unlike eccrine glands (which produce clear, watery sweat), apocrine glands secrete a thicker fluid rich in proteins and lipids—essentially laying out a buffet for bacteria. These glands cluster in your armpits, groin, and around hair follicles, which explains why these areas tend to develop stronger smells.

Several factors can influence your personal aroma:

1. Medical conditions

Sometimes that persistent smell isn't just about hygiene. Several health conditions can alter your body's natural scent:

  • Liver or kidney disease: When these organs can't properly filter toxins, those compounds may be released through sweat
  • Thyroid imbalances: An overactive thyroid increases metabolism and sweating
  • Diabetes: Poorly controlled blood sugar can lead to a sweet or fruity smell (particularly noticeable on the breath)
  • Infections: Bacterial infections like UTIs or bacterial vaginosis often produce distinctive odours

2. Environmental factors

Your environment plays a significant role in sweat production and odour development:

  • Temperature: Hot, humid weather naturally increases perspiration
  • Physical activity: Vigorous exercise triggers both cooling sweat and stress-related sweat
  • Stress levels: Emotional stress activates apocrine glands, producing thicker, odour-prone sweat

3. Genetic factors

Some of us are simply more prone to body odour through no fault of our own. Hyperhidrosis—excessive sweating that affects approximately 3% of Australians according to the International Hyperhidrosis Society—can be genetic and significantly increases odour challenges.

Natural solutions for managing body odour

The good news? You don't need harsh chemicals to manage body odour effectively. Nature offers plenty of solutions that can help you stay fresh without compromising your health or the environment.

Daily habits that make a difference

Let's start with the basics that make an enormous difference:

  • Shower strategically: Focus on thorough cleaning of odour-prone areas using mild, natural soaps. Timing matters too—a quick rinse after exercise prevents bacteria from multiplying.

  • Clothing choices: Natural, breathable fabrics like cotton, linen, and bamboo allow sweat to evaporate rather than creating the warm, moist environment bacteria love. Consider moisture-wicking fabrics for exercise.

  • Diet adjustments: You've heard "you are what you eat"—and your smell reflects it too. Foods that may intensify body odour include:

    • Red meat and high-fat animal products
    • Strong-smelling vegetables (garlic, onions, cabbage, cruciferous vegetables)
    • Alcohol (which releases through pores as your body processes it)
    • Spicy foods (which increase sweating and release aromatic compounds)

You might be surprised how much difference dietary changes can make—many people report noticeable improvements within just a week of adjusting what's on their plate. But beyond these preventative measures, there are several natural remedies that can directly combat existing odour issues.

Natural remedies worth trying

Before reaching for commercial products loaded with chemicals, consider these time-tested natural solutions that many people find effective for managing body odour. These remedies harness the power of simple ingredients to create an environment where odour-causing bacteria simply can't thrive.

Apple cider vinegar rinse: Apple cider vinegar creates an acidic environment where odour-causing bacteria struggle to survive. After showering, mix one part apple cider vinegar with four parts water and apply to odour-prone areas (avoiding any broken skin). Let it air dry for maximum effectiveness.

Baking soda applications: This kitchen staple works wonders for neutralising odours. After showering, apply a light dusting of baking soda to your underarms or feet. For a more convenient application, mix baking soda with a small amount of coconut oil to create a natural deodorant paste.

Probiotic power: The "good" bacteria in probiotics can help restore balance to your skin's microbiome. Research from the University of Melbourne has shown promising results for using probiotics to combat odour-causing bacteria, particularly for conditions like bacterial vaginosis. Incorporate fermented foods like yoghurt, kimchi or kombucha into your diet, or consider a high-quality probiotic supplement.

Essential oil solutions: Several essential oils offer powerful antibacterial properties that help control odour:

  • Tea tree oil: Dilute 2-3 drops in a tablespoon of carrier oil (like coconut or jojoba) and apply to freshly washed skin
  • Lavender oil: Not only antibacterial but also helps reduce stress-related sweating
  • Witch hazel: A natural astringent that temporarily tightens pores and reduces perspiration

Stay hydrated, stay fresh: Proper hydration helps flush toxins from your system before they reach your sweat glands. Aim for at least 2 litres of water daily, and incorporate water-rich foods like cucumber, watermelon, and citrus fruits into your diet.

When to seek professional help

While natural remedies work wonderfully for everyday body odour, persistent or severe cases might require professional intervention. Consider consulting a healthcare provider if:

  • You've tried multiple natural approaches without improvement
  • Your body odour has changed dramatically without lifestyle changes
  • You're experiencing excessive sweating that interferes with daily activities
  • Your body odour is accompanied by other symptoms like unexplained weight loss, fever, or fatigue

A qualified naturopath or integrative medicine practitioner can help identify underlying causes and develop a personalised treatment plan that addresses your specific needs.

Embracing your natural self

Remember, some level of body odour is completely normal and part of being human. The goal isn't to eliminate your natural scent entirely—that's neither possible nor desirable—but rather to maintain a healthy balance that leaves you feeling confident and comfortable.

If you're struggling with persistent body odour issues, consider consulting with a qualified naturopath who specialises in detoxification. These practitioners can provide personalised guidance based on your unique body chemistry, helping you address the root causes rather than just masking symptoms.

FAQs

Why does body odour smell the way it does?

When bacteria on your skin come into contact with sweat, they produce body odour. Bacteria are naturally present on our skin and don't cause any odour. However, when it mixes with sweat, salt and fat, it causes a certain odour that can be either good or bad.

What are the 5 causes of body odour?

In addition to bad hygiene habits like not showering and changing your clothes on a daily basis, what you eat contributes to body odour. Excessive consumption of spicy foods, sweets or sugar-laden foods, and alcohol can also cause your body to smell foul. Other contributing factors include excessive sweating from physical activity and a medical condition.

What is your body odour telling you?

The way a person smells can indicate how much attention they pay to their hygiene habits, or it can be a sign of a health problem. It's easy to blame poor hygiene practices for body odour, but we should keep in mind that certain conditions, such as typhoid fever, can also cause the body to smell strange.
