THERE’S A STUBBORN LITTLE STEREOTYPE ABOUT Indian men and how they smell. The curries, is it? Something in the cooking, the climate, or perhaps the culture—the racist Western narrative we’ve heard growing up. The inconvenient truth is that the science points the finger almost everywhere except where the stereotype wants it to.
Smell isn’t a hygiene scandal or a referendum on your upbringing. It’s biology—and biology, it turns out, has bad news for everyone who thinks they’re above it.
First, some reassurance: it’s probably not your fault. Body odour has spent decades being treated as a moral failing: a verdict on how often you bathe, what you eat, whether you’re “clean”. Most of that is nonsense, and the truth is a lot more interesting.
“Fresh sweat is essentially odourless,” says Dr Mikki Singh, board-certified dermatologist and founder of Bodycraft Clinics. The smell shows up later, when the bacteria living on your skin get to work. “They feed on those secretions and break them down into volatile compounds,” she explains, referring to the sour, sweaty notes, and the pungent, onion-y thioalcohol smell “that’s very characteristic of armpits.” Body odour, in other words, is a by-product. The sweat is just raw material while the bacteria do the cooking.
Dr Bindu Sthalekar, dermatologist and founder of Skin Smart Solutions, puts it plainly: your underarms have a special kind of sweat gland that pumps out sweat rich in proteins and fats. "When the bacteria break down these substances along with sweat, they release what we know to be body odour."
Here’s the part that should end a few arguments. “A lot of it is genetics,” says Dr Singh. People differ in how many sweat glands they have, how active those glands are and—crucially—in the exact community of bacteria living on their skin. “Two people can wash identically and host very different microbial communities,” she adds.
The science backs up well. A single gene— ABCC11—largely decides whether your sweat even carries the raw molecules bacteria need to make a stink. One version of it switches the odour off almost entirely. That version is wildly common in East Asia, carried by an estimated 80–95% of people, and genuinely rare in Europe and Africa, where the overwhelming majority carry the odour-producing variant.
So, according to the cold logic of genetics, the populations most lazily associated with body odour are not, in fact, the ones built to smell the most. And India? Genetically all over the map—in one study, 54% of Dravidian people from Tamil Nadu carried the low-odour version. So the tired “curry sweat” cliché isn't just rude, it’s also biologically incoherent.
“You are what you eat,” agrees Dr Sthalekar. Common offenders include food that is sulphur-heavy: garlic, onions and cruciferous vegetables like broccoli and cabbage. Garlic is the classic—your body can’t fully break it down, so the compounds get exhaled and pushed out through the skin for hours after the meal. Heavy spicing (cumin, fenugreek) can carry through into sweat, too.
Having said that, you don’t need a complete switch. According to Dr Singh, diet is a modifier and not the main driver. It wouldn’t rewrite your baseline, but for heavy consumers, “easing off noticeably softens the edges,” says Dr Singh.
Water, she adds, is a surprisingly commonly missed variable. Dehydration concentrates your sweat and intensifies the smell.
India is a year-round stress test because the heat and humidity are perfect environment for the bacteria, confirms Dr Singh. The strategy here has to be less about scrubbing and more about moisture control. Both experts land on roughly the same routine and it’s refreshingly low on product.
Shower once or twice a day, paying attention to the armpits, groin and feet, and then, the most important one: dry off properly.
“A lot of ‘I showered and still smell’ comes from not drying properly,” says Dr Singh, since bacteria thrive in a damp fold. Although it doesn’t make a huge difference, but trimming underarm hair can help in some situations since it gives the bacteria less surface area to colonise and makes it easier for the product to reach the skin.
When it comes to clothing, favour cotton and linen over synthetics, which trap odour and rerelease it. Change your shirt daily, and don’t re-wear a sweat-soaked one.
Many men still get the difference between deodorants and anti-perspirants wrong. A deo masks the smell and targets bacteria, while the latter is aluminium-based and actually works on reducing sweat. In this climate, the anti-perspirant has the edge. Dr Singh advises applying it at night, on clean and dry skin. It may sound counterintuitive, but dermatologists are unanimous on it: your sweat glands are quietest while you sleep, which lets the active ingredient plug the ducts and carry through the next day. Slapping it on damp skin before you sprint for the metro barely works.
Most body odour is biology, not pathology but a few patterns deserve professional attention.
“Odour that persists despite genuinely good hygiene, or a sudden change in how someone smells, is usually a flag,” says Dr Singh. And of course, do note the specifics—a sweet, fruity smell can signal uncontrolled diabetes and a persistent fishy note can point to a metabolic or liver/kidney issue. And if you sweat so heavily it soaks through your clothes and derails your day, that’s hyperhidrosis—very real, very treatable, often with Botulinum toxin injections.
Odour is biology, not always a verdict on someone’s personal hygiene. Manage it like the logistics problem it is and stop apologising for being a mammal.
