Americans only became intolerant of body odor in the last century

Americans spent $6.6 billion on body odor products in 2023

This high figure from Euromonitor, a research firm, suggests Americans spent more on deodorant than in any other country. Beyond deodorant, there's also growing interest in "whole body" deodorant designed to mask smells from various parts of the body beyond the armpit.

An antiperspirant ad campaign in the early 1900s dubbed body odor "B.O."

The product was marketed toward women and framed excessive sweating as a medical disorder that needed to be addressed with the product.

A 2025 study explored the common words to describe body odor across 17 countries

The work identified the 25 most frequent words used to describe body odors across languages, ranked by frequency, and found that "sweaty" topped the list, followed by "sour" and "stinky."

Sweat doesn't smell, but bacteria multiply in moist environments—and cause an odor

Body odor is associated with sweat, but odor actually arises from the bacteria that multiply in moist environments on your skin. Hormones, medications, food, and body hair can all affect body odor.

Most people with East Asian ancestry are genetically predisposed to be less smelly.

'Old people' smell is real—it's a chemical buildup when fatty acids on the skin oxidize

The chemical composition of body odor seems to change with age. Later in life, we harbor higher concentrations of a chemical compound called 2-nonenal that forms when omega-7 fatty acids on the skin oxidize, and the skin's natural antioxidant defenses weaken. Commonly called "nonenal", it's the smell widely associated with aging, and it's often described as a grassy or greasy odor.

After World War I, consumerism began to usurp frugality as a foundational value in American life and culture.

America generates more trash per person than any other country on Earth

The US produces roughly 292 million tons of municipal solid waste per year, about 4.9 pounds per person per day. Municipal solid waste includes food scraps, packaging, electronics, yard trimmings, and more. About 50% of the waste ends up in a landfill.

Analysis of body odors from individuals aged 26 to 75 confirmed that 2-nonenal, an unsaturated aldehyde with an unpleasant, greasy, and grassy odor, was detected only in subjects aged 40 and older.

Corynebacterium species are particularly responsible for our funky smell

Myriad bacteria contribute to our body odor, but research suggests that Corynebacterium species are strongly associated with the bad smells emanating from adults. Staphylococcus and Cutibacterium genera may also play leading roles.

Gen Z's love for perfume is boosting sales

Teen boys are the biggest driver in perfume sales as of the summer of 2025. They have increased their spending on fragrances 26% year-over-year as the trend blossoms on TikTok via #PerfumeTok. Additionally, users of weight loss drugs GLP-1 agonists are adding to sales, as they seek olfactory over culinary sensations.

Roughly 15 of every 1,000 people in the US have smell disorders

Anosmia is a lack of a sense of smell. It can be present at birth, related to diseases including Parkinson's, Alzheimer's, and COVID-19, or have unknown causes.

Bidets have been considered taboo throughout US history

While bidets are a typical household essential in Europe, Asia, and South America, they remain uncommon in the US. Associations with infertility, the aristocracy, and brothels helped fuel their unpopularity in the states.

Carboxylic acids are one reason teens are smelly

Scientists compared the smells of babies and teenagers and identified some of the compounds that make teens smelly. Carboxylic acids present in teens, they wrote, seemed to give off an "earthy, musty, or cheesy" scent. This 2024 research could help inform future odor-control products.

Modern roll-on deodorant design was modeled on the ballpoint pen

Instead of a messy cream, which had been the norm in the 1940s, a new roll-on deodorant inspired by the easy flow of a ballpoint pen debuted in 1952.

Cookout and barbecue culture boomed in post-war 1950s America

Magazines like "Life" fueled the outdoor cooking craze, and by 1955, barbecue had grown into a $100 million industry. American Studies scholar Kristin L. Matthews explains that the trend fit neatly with Cold War-era consumerism and the emphasis on home ownership.

The adoption of modern appliances led to the soap opera's rise

Soaps grew more popular as they transitioned to television in the 1950s. At the same time, the adoption of modern appliances like the automatic dishwasher and the clothes dryer offered housewives more free time, which soaps could now occupy. By 1970, CBS, NBC, and ABC were airing 18 daytime soaps.

Estée Lauder once broke a bottle of the hit perfume 'Youth Dew' to convince French department stores to carry the product

Youth Dew, originally launched in 1953 as a bath oil, was wildly successful in the American market and one of the early products that cemented Estée Lauder as a luxury cosmetics brand. When the Galeries Lafayette in Paris hesitated to sell the perfume, Lauder "accidentally" broke a bottle of Youth Dew, causing the smell to spread throughout the department store. Shoppers began asking for the scent, and the department store agreed to sell it.

Cremations are America's top choice for postmortem body treatment

Though this process is the most popular one, more Americans are becoming interested in "green" burials that don't involve slowly degrading coffin materials, toxic embalming fluids or emissions from crematoria.

Modern conveniences may be contributing to allergy increases

A combination of genetics and how the environment changes our genes are likely contributing to the rise in allergies. But daily conveniences, such as dishwashers and packaged baby food, also change the level of bacterial exposures in early life, with potential implications for allergy development, experts from Mount Sinai Health System state in this video discussion.

In 2024, Americans bought over $7B of cut flowers

Americans spent an estimated $14.8B for the Fourth of July 2025.

Even in recent history, adaptations to the environment drove human evolution

Through genetics, environmental pressures, and cultural influences, humans have evolved to tolerate lactose, develop varying skin pigmentation, and acquire genetic resistance to diseases like bubonic plague. The metabolic and digestive systems of Indigenous peoples have adapted to their diet, which is influenced by the availability of food and water.

1 in 15 adults over age 40 experience phantom odors

This phenomenon was measured in a 2018 study that examined the prevalence and risk factors for phantom odor perception. Older adults were less likely to experience these phantom odors as they age, just as their overall sense of smell declines. Women are more likely than men to perceive phantom odors.

Obesity rates have more than doubled worldwide since 1990

In the US alone, the percentage of the population meeting the clinical standard of obesity rose from less than 20% to more than 40% over the past three decades. This rise has been matched by many countries across the globe, from industrialized to developing nations.

There's a widespread taboo around talking about money in the US, but that taboo is widely different across the lower and upper classes, as well as amongst different races.

In the United States, asking someone how much money they make (or any questions about money, really) has long been considered rude. But where did this social norm come from originally? And why do Americans still feel so awkward talking about money? This article from The Atlantic takes a deep dive into the socioeconomic forces that created the money taboo. Read the full piece here.

The mean net worth for an American household is now $1M

That's according to 2024 data from the Federal Reserve. In 1848, just 50 households had achieved a net worth of at least $1M (roughly $40M in today's dollars). Millionaires have become significantly more common due to a multitude of factors, such as price increases in securities, inflation, and rising home values.

Here's how much money Americans spend on Halloween

In 2024, Americans are expected to spend more than $11B on Halloween, which averages out to roughly $104 per person, according to the National Retail Federation's Halloween Spending Survey, conducted by Prosper Insights & Analytics. That $11B number includes an anticipated almost $4B spent on costumes. See the full breakdown here.

Antiperspirants work better if they are applied at night

Dermatologists recommend applying antiperspirant at night for the best results. When applied to clean, dry skin at night, the active ingredient in most antiperspirants (aluminum salt), combined with the skin's natural moisture, forms plugs that block sweat glands, limiting sweat and related odors.

Most of the 86,000 consumer chemicals registered with the US EPA have never received rigorous toxicity testing, though not all those are still in current use.

The health food industry grew significantly in the early 1990s

By 1996, there were over 6,000 health food stores in the US, which generated over $9B in sales. That was still a small number compared to traditional supermarkets, but it was a 17% improvement in annual growth over the previous five years, highlighting a rapidly growing industry.

Humans may be able to distinguish more than one trillion scents

That's according to one estimate published in 2014. This figure far exceeds earlier estimates of a human smelling ceiling around 10,000 odors. The newer figure is derived from experiments in which volunteers agreed to sniff varying scents. Researchers mixed odor components and had volunteers sniff the brews to detect subtle scent differences. (Some users may experience a paywall.)

In the 19th century, ice-cream-related illnesses were somewhat regular in America thanks to vendors' poor hygienic practices.

Health food broke into the mainstream by the 1980s

A 1984 New York Times story noted that Americans were eating less red meat than a decade prior, and that, in general, the country was “talking, thinking and worrying about what they eat to a degree unique in the nation's history.” The feature then details foods that were then considered bizarre: whole-grain muffins, hummus, and a variety of vegetarian dishes. (Some readers may experience a paywall.)

Nearly 9 in 10 Americans were annoyed by tipping as of 2025

That’s a sharp increase from the 75% who thought tipping culture had gone too far in 2024. One potential culprit? The proliferation of tipping screens in places outside sit-down restaurants, such as coffee shops and hair salon. Three in 10 Americans say they give less when presented with tipping screens.

Most Americans are now dying at home, reversing 20th century trends

For most of the 21st and 20th centuries most Americans died in hospital settings. But in 2016, home-based deaths overtook hospitals; most Americans are now dying at home, likely fueled by individual preferences to die at home or to receive at-home palliative care.
