Let’s face it, everyone sweats, and with that, body odour happens. It’s completely normal and part of being human. But while a little odour is natural, excessive or strong-smelling BO (body odour) can impact your confidence, relationships, and even signal underlying health concerns.
Let’s break it down: what causes body odour, how to manage it, and when it might need medical attention.
What causes body odour?
Surprisingly, sweat itself doesn’t smell. It’s actually bacteria on your skin that break down the proteins in sweat — and that’s what creates odour.
Your body has two types of sweat glands:
-
Eccrine glands: Found all over your body, producing odourless sweat to cool you down.
-
Apocrine glands: Found in your underarms, groin and scalp — these activate during stress or hormonal changes and produce sweat rich in proteins (which bacteria love).
Common causes of stronger body odour:
-
Poor hygiene (not washing regularly or thoroughly)
-
Tight or synthetic clothing that traps sweat
-
Spicy or strong-smelling foods (like garlic, onions, red meat)
-
Puberty or hormonal changes
-
Stress or anxiety (which activate apocrine glands)
-
Medical conditions (like diabetes or thyroid problems)
-
Certain medications or supplements
How to manage and reduce body odour
1. Shower regularly
Daily showers — especially after sweating — help remove bacteria and odour. Use an antibacterial soap for extra freshness.
2. Dry off completely
Bacteria thrive in damp places. After bathing, dry underarms, feet and skin folds thoroughly.
3. Choose breathable clothing
Natural fabrics like cotton or bamboo let your skin breathe. Change clothes daily, especially socks and underwear.
4. Use deodorant or antiperspirant
-
Deodorant masks smell but doesn’t stop sweating.
-
Antiperspirant blocks sweat glands temporarily to reduce sweat.
Try fragrance-free options if you have sensitive skin.
5. Watch your diet
Certain foods can make your sweat smell stronger. If you notice a link between what you eat and how you smell, try adjusting your intake.
6. Stay hydrated
Drinking water helps flush toxins and can reduce the concentration of compounds in your sweat.
When body odour could be a sign of something more
While most BO is normal, speak to a doctor if you notice:
-
A sudden or dramatic change in odour
-
A fruity or ammonia-like smell (which may signal diabetes or kidney issues)
-
Excessive sweating not related to heat or exercise (called hyperhidrosis)
-
Rashes, discharge, or skin irritation along with odour
Body odour and puberty
Teens often experience stronger BO as hormones kick in. It’s totally normal, and a great time to teach healthy hygiene habits. Encouraging open conversations and self-care routines can help boost confidence and wellbeing.
It’s natural, and manageable
Body odour doesn’t have to be embarrassing. With a few small hygiene tweaks, you can stay fresh, feel confident and support your overall health. And if you feel something’s off, trust your nose, and talk to your doctor.
