Body Odour and
Smelly Armpits
What is a
smelly armpit odour?
Armpit odour, often referred to as body odour, is the natural scent produced by your body as a result of sweat and bacteria interacting on the skin’s surface. This odour can vary from person to person due to factors such as genetics, diet and overall health. While sweat itself is odourless, the bacteria on your skin break it down, leading to the release of volatile compounds that can create an unpleasant smell.
By keeping up good personal hygiene through regular bathing, wearing breathable clothing and using antiperspirants or deodorants, you can really help to minimise and manage bad armpit odour effectively.
6 Common areas for
body odour
Body odour can crop up in various areas of your body, but it’s most commonly associated with the following places because they have a higher concentration of sweat glands:
- Armpits: Your underarms are one of the primary locations for body odour because they contain a high density of sweat glands. When sweat mixes with bacteria on the skin’s surface, it can result in a noticeable odour.
- Groin area: The genital and perianal areas also have a significant number of sweat glands. Sweat and bacteria can combine in these regions, leading to a distinct odour.
- Feet: Feet are prone to body odour because they have many sweat glands, especially on the soles. When feet sweat and come into contact with moisture-absorbing shoes or socks, it creates an environment where bacteria thrive, causing foot odour.
- Chest and back: The chest and back have sweat glands, and in some people, particularly those who do a lot of physical activity, body odour can develop in these areas.
- Hair and scalp: Scalp odour can occur when sweat mixes with oils and hair products. It’s less common than underarm or foot odour but can be noticeable in some cases.
- 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 primarily 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 the interaction between sweat and bacteria on the skin’s surface. Sweat is mostly made up of water and salt, but when bacteria break sweat down, it can produce unpleasant odours.
- Apocrine sweat glands: Apocrine sweat glands, found primarily 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 and more noticeable odour.
- Hormonal changes: Hormonal fluctuations, such as those during puberty, menopause or pregnancy, can lead to increased sweat production and changes in armpit odour. Hormones can influence the activity of sweat glands which can contribute to a changing body odour.
- Dietary choices: The foods you eat can influence your body odour. Strong-smelling foods like garlic, onions and spices contain sulphur compounds that can be excreted through sweat and breath, which can contribute to an unpleasant odour, such as onion-smelling sweat.
- Stress and anxiety: Emotional stress and anxiety can stimulate your sweat glands, leading to increased perspiration. Stress sweat often contains more proteins and fatty acids, providing a favourable 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 addressing any underlying medical conditions are all effective strategies.
How to prevent
body odour and smelly armpits?
Preventing unpleasant body odour and smelly armpits is all about keeping up good hygiene and making a few lifestyle choices to minimise sweating and bacterial growth. Here are 10 tips on how you can prevent body odour:
- Frequent showering: Take daily showers using a mild, antibacterial soap. Cleanse all areas prone to sweating, including your armpits, groin and feet. Showering helps remove smelly sweat and bacteria from your skin’s surface.
- Use antibacterial soap: Choose a soap that has antibacterial properties to further reduce the bacteria on your skin.
- Shave or trim: Consider shaving or trimming areas with dense hair growth, such as your underarms. Hair can trap sweat and bacteria, creating an environment for odour to develop.
- Stay hydrated: Drink plenty of water to maintain proper hydration. Staying hydrated can help regulate your body temperature and reduce excessive sweating. It’s recommended to drink 1.5–2 litres of water a day.
- Choose breathable fabrics: Wear clothing made from breathable materials like cotton or moisture-wicking fabrics. These fabrics allow air to circulate and help prevent sweat build-up. Wearing these fabrics while you sleep can also help to soften strong body odour at night.
- Maintain a healthy diet: Try to avoid strong-smelling foods like garlic, onions and spicy dishes, as they can contribute to body odour. Go for a balanced diet that’s rich in fruits, vegetables and whole grains.
- Limit caffeine and alcohol: Caffeine and alcohol can increase sweating, so try to limit how much you have, especially in hot weather.
- Manage stress: High stress levels can trigger sweat glands. Build in some stress-reduction techniques like meditation, yoga or deep breathing exercises.
- Regular exercise: Keeping active supports your overall health and can help reduce stress. Just make sure you shower and change clothes promptly after exercise to remove sweat and bacteria.
Remember that armpit odour is a natural occurrence and some level of odour is completely normal. However, by following these simple steps, you can really manage and improve body odour so you stay feeling fresh and confident.
If you’ve got persistent or very strong body odour despite good hygiene, it’s a good idea to speak to a healthcare professional.
Smelly armpit odour facts

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 dietary choices, hormonal changes or stress, NIVEA is here with solutions. Here’s a simple but effective body care routine to help you smell good and reduce unpleasant body odour and smelly armpits.
Shower and cleanse:
Begin your body care routine by taking 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 crucial to get 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, consider shaving or trimming it as needed. Hair can trap sweat and bacteria, providing an environment for odour to 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 control your sweat and odour. Antiperspirants help reduce sweat production, while deodorants help to 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 48-hour protection from sweat and body odour, whilst caring for your skin.
Remember that everyone’s body is different, so you might need to tweak your routine to fit your specific needs and preferences. NIVEA’s range of body care products is designed to help you stay fresh and confident throughout the day.
What does your odour scent say
about your health?
- Garlic or onion odour: Persistent garlic- or onion-scented sweat may be linked to your diet. These foods contain sulphur compounds that can be released through your sweat and breath. To combat this smell, try reducing how often you eat these foods or improving your oral hygiene routine.
- Sour or vinegary odour: If you notice a sour or vinegary odour coming from your body, it could be a sign of stress and anxiety. Stress can lead to excess sweat and changes in your body’s pH levels, resulting in this distinct smell. Building stress-reduction techniques like meditation or yoga into your routine can help combat this odour.
- Sweet or fruity odour: A sweet or fruity scent coming from your body might indicate 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 can be essential steps in managing this odour and looking after your overall health.
- Ammonia-like odour: An ammonia-like smell might be a sign of 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 excessive moisture and not drying your skin properly, leading to fungal or bacterial growth. Musty body odour can often be prevented by drying your skin thoroughly after bathing, using moisture-wicking clothing and applying antifungal or antibacterial creams if needed to prevent such odours.
- Fishy odour: A fishy odour, especially in women, could be associated with bacterial vaginosis, a common vaginal infection. Keeping up good genital hygiene, wearing breathable cotton underwear and seeking medical advice if the odour persists can all help tackle this issue.
Individual body odours can vary a lot, so it’s important to pay attention to any changes. Using these insights in your body care routine can help you proactively address potential concerns. If you’re 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 the patterns and intensity. Men typically have a higher density of sweat glands, especially in areas like the armpits, which can lead to more pronounced sweating. This increased sweat production can create an environment where bacteria thrive, potentially resulting in stronger body odour.
NIVEA MEN deodorants put personal hygiene and odour prevention first, offering caring formulas and long-lasting freshness for your everyday activities. With options ranging from sticks to sprays, roll-ons and atomisers, there’s a choice for every preference, all infused with masculine scents.
Women may experience hormonal fluctuations during their menstrual cycles, pregnancy or menopause, which can affect the timing and intensity of sweating and body odour.
Whatever your gender, keeping up good hygiene and using the right products, like antiperspirants or deodorants, can really help you manage and reduce body odour effectively.
If you’re looking for a long-lasting antiperspirant with a fresh scent of sensual flowers and juicy berries, the NIVEA Fresh Sensation Antiperspirant provides reliable protection for up to 72 hours. It’s made with a unique NIVEA INFINIFRESH formula, which doesn’t just mask odour but effectively targets bacteria before bad odour can even develop.
