Body Odour and
Smelly Armpits
What is a
Smelly armpit odour?
Armpit odour, often referred to as body odour, is the natural scent your body produces when sweat and bacteria interact on the skin’s surface. This odour can vary from person to person due to factors such as genetics, diet and overall health. Sweat itself is odourless, but when the bacteria on your skin break it down, they release volatile compounds that can create an unpleasant smell.
By keeping up good personal hygiene – like regular showers, wearing breathable clothing and using antiperspirants or deodorants – you can help minimise and manage bad armpit odour effectively.
6 Common areas for
body odour
Body odour can pop up in different areas of your body, but it’s most commonly linked to the following spots because they have a higher concentration of sweat glands:
- Armpits: Your underarms are one of the main areas for body odour because they contain a high density of sweat glands. When sweat mixes with bacteria on the skin’s surface, it can lead to a noticeable odour.
- Groin Area: The genital and perianal areas also have a lot of sweat glands. Sweat and bacteria can combine here too, leading to a distinct odour.
- Feet: Your feet are prone to body odour because they have many sweat glands, especially on the soles. When your feet sweat and are inside moisture-absorbing shoes or socks, it creates an ideal environment for bacteria to thrive, causing foot odour.
- Chest and Back: The chest and back have sweat glands as well, and if you’re active or work out a lot, body odour can develop in these areas.
- Hair and Scalp: Scalp odour can happen when sweat mixes with oils and hair products. It’s less common than underarm or foot odour but can still be noticeable for some people.
- Face: Although not as common as other areas, facial sweat combined with bacteria can lead to facial body odour, especially in hot and humid conditions.
The common causes of
armpit odour
Body odour, including smelly armpits, is mainly caused by the interaction between sweat and bacteria on your skin. Here are 6 common causes:
- Sweat and Bacteria Interaction: The most common cause of a smelly armpit odour is sweat mixing with bacteria on the skin’s surface. Sweat is mostly made up of water and salt, but when bacteria break it down, it can produce unpleasant odours.
- Apocrine Sweat Glands: Apocrine sweat glands, mainly found in areas like your armpits, groin and scalp, produce a thicker type of sweat that contains proteins and lipids. When this sweat interacts with bacteria, it can create a stronger, more noticeable odour.
- Hormonal Changes: Hormonal ups and downs – like during puberty, menopause or pregnancy – can ramp up sweat production and change your armpit odour. Hormones affect how active your sweat glands are, which can lead to a changing body odour over time.
- Dietary Choices: What you eat can influence your body odour. Strong-smelling foods like garlic, onions and spices contain sulphur compounds that can be released through sweat and breath, contributing to an unpleasant odour, such as onion-smelling sweat.
- Stress and Anxiety: Emotional stress and anxiety can activate your sweat glands, leading to increased perspiration. Stress sweat often contains more proteins and fatty acids, which provide a great environment for odour-producing bacteria.
To combat smelly armpits and unpleasant body odour, keeping up good personal hygiene, using antiperspirants or deodorants, wearing breathable clothing and speaking to a doctor about any underlying medical issues are all effective strategies.
How to prevent
body odour and smelly armpits?
Preventing unpleasant body odour and smelly armpits is all about good hygiene and a few lifestyle tweaks to minimise sweating and bacterial growth. Here are 10 tips on how you can help prevent body odour:
- Frequent Showering: Take a daily shower using a mild, antibacterial soap. Pay extra attention to areas that sweat more, like your armpits, groin and feet. Showering helps wash away smelly sweat and bacteria from your skin’s surface.
- Use Antibacterial Soap: Choose a soap with antibacterial properties to further help reduce the bacteria on your skin.
- Shave or Trim: Think about shaving or trimming areas with lots of hair, such as your underarms. Hair can trap sweat and bacteria, creating an environment where odour can develop more easily.
- Stay Hydrated: Drink plenty of water to stay properly hydrated. Staying hydrated helps regulate your body temperature and can reduce excessive sweating. It’s generally recommended to drink around 1.5 – 2 litres of water a day.
- Choose Breathable Fabrics: Wear clothing made from breathable materials like cotton or moisture-wicking fabrics. These allow air to circulate and help prevent sweat build-up. Wearing these kinds of fabrics to bed can also help reduce strong body odour at night.
- Maintain a Healthy Diet: Try to limit strong-smelling foods like garlic, onions and very spicy dishes, as they can contribute to body odour. Aim for a balanced diet with plenty of fruits, vegetables and whole grains instead.
- Limit Caffeine and Alcohol: Caffeine and alcohol can increase sweating, so it can help to cut back, especially in hot weather.
- Manage Stress: High stress levels can trigger your sweat glands. Try stress-reduction techniques like meditation, yoga or deep breathing exercises to help keep stress sweat under control.
- Regular Exercise: Regular physical activity supports your overall health and can help reduce stress. Just make sure you shower and change into clean clothes soon after exercise to remove sweat and bacteria.
Remember, armpit odour is a natural part of being human and a certain level of scent is totally normal. But by following these simple steps, you can seriously improve and manage body odour so you feel fresher and more confident every day.
If you notice persistent or very strong body odour even with good hygiene, it’s a good idea to chat to a healthcare professional.
Smelly armpit odour facts
Characteristics: An unpleasant smell that comes from your underarms due to sweat being broken down by bacteria on the skin.
Causes: Smelly armpits happen when sweat mixes with bacteria on the skin’s surface. Sweat itself is usually odourless, but once it interacts with bacteria, it produces a distinct smell.

NIVEA Body Care Routine
to manage smelly armpits and body odour
Armpit odour can be unpleasant and make you feel self‑conscious. Whether it’s triggered by what you eat, hormonal changes or stress, NIVEA is here with simple solutions. Here’s a handy body care routine to help you smell good and reduce unpleasant body odour and smelly armpits.
Shower and Cleanse:
Start your body care routine with a shower. Showering helps remove sweat odour, bacteria and impurities from your skin’s surface. Bacteria thrive in warm, damp conditions, so this step is key to getting rid of odour‑causing microbes.
Exfoliate (1–2 times a week):
Exfoliating once or twice a week helps remove dead skin cells that can trap bacteria and contribute to odour. Use a gentle exfoliating scrub to keep your skin feeling fresh and smooth.
Shave or Trim:
If you have body hair, think about shaving or trimming it when you need to. Hair can trap sweat and bacteria, creating an environment where odour can develop. Removing or trimming body hair can help reduce bacterial growth and improve how well your deodorant or antiperspirant works.
Apply Antiperspirant or Deodorant:
Apply an antiperspirant or deodorant to help keep sweat and odour under control. Antiperspirants help reduce how much you sweat, while deodorants help mask and neutralise odour. NIVEA offers a range of antiperspirants and deodorants that provide long-lasting protection and a pleasant fragrance. Suitable for all skin types, the NIVEA Black & White Clear Original Anti-Perspirant Deodorant Spray is formulated to help provide up to 72 hours of hydration, protection from sweat and body odour, while caring for your skin.
Remember, everyone’s body is different, so you might need to tweak your routine to fit what works best for you. NIVEA’s range of body care products is designed to help you feel fresh and confident all day long.
What does your odour scent say
about your health?
- Garlic or Onion Odour: Persistent garlic‑ or onion‑scented sweat is often linked to what you eat. These foods contain sulphur compounds that can be released through your sweat and breath. To help combat this smell, try cutting back on these foods or stepping up your oral hygiene routine.
- Sour or Vinegary Odour: If you notice a sour or vinegary odour coming from your body, it can sometimes be a sign of stress and anxiety. Stress can cause excess sweating and change your body’s pH levels, leading to this distinct smell. Adding stress‑reduction techniques like meditation or yoga into your routine can help ease this type of odour.
- Sweet or Fruity Odour: A sweet or fruity scent coming from your body might be linked to high blood sugar levels, which can be a sign of diabetes. Regular exercise, a balanced diet and keeping an eye on your blood sugar levels are important steps in managing this odour and looking after your health.
- Ammonia‑Like Odour: An ammonia‑like smell might point to possible kidney issues, as it can indicate a build‑up of waste products in your body. Staying hydrated and eating a diet rich in kidney‑friendly foods, like leafy greens and berries, can help reduce this odour and support kidney function.
- Musty Odour: A musty or mildew‑like smell can result from too much moisture and not drying off properly, which can lead to fungal or bacterial growth on the skin. Musty body odour can often be prevented by drying your skin thoroughly after bathing, wearing moisture‑wicking clothing and using antifungal or antibacterial creams if needed.
- Fishy Odour: A fishy odour, especially in women, can be associated with bacterial vaginosis, which is a common vaginal infection. Maintaining good genital hygiene, wearing breathable cotton underwear and seeing a healthcare professional if the odour sticks around can all help address this issue.
Everyone’s natural scent is different, so it’s important to pay attention to changes in your body odour. Using these insights in your body care routine can help you stay on top of any potential concerns. If you’re ever worried about a sudden change in your body odour, it’s best to visit your doctor for advice.
Gender differences in
BODY ODOUR AND SWEATING
Sweating and body odour are natural processes that affect both men and women, but there can be differences in how strong and how often they occur. Men usually have a higher density of sweat glands, especially in areas like the armpits, which can lead to more noticeable sweating. This extra sweat can create an environment where bacteria thrive, which may result in stronger body odour.
NIVEA MEN deodorants are designed with everyday life in mind – helping you stay on top of personal hygiene and odour prevention, while offering caring formulas and long‑lasting freshness. Whether you prefer sprays or roll‑ons, there’s an option to suit you, all with masculine scents.
Women may notice that hormonal fluctuations during their menstrual cycle, pregnancy or menopause can affect when and how much they sweat, and how strong their body odour is.
No matter your gender, keeping up good hygiene and using products like antiperspirants or deodorants can really help you manage and reduce body odour effectively.
If you’re after a long‑lasting antiperspirant with a fresh scent of sensual flowers and juicy berries, the NIVEA Fresh Sensation Antiperspirant offers reliable protection for up to 72 hours. It’s made with a unique NIVEA INFINIFRESH formula that doesn’t just mask odour, but helps eliminate bacteria before bad odour can even appear.
