Scented Laundry Products Release Carcinogens, Study Finds

Scented laundry detergent and dryer sheets make laundry smell great – but do they cause cancer?

A small study suggests scented laundry items contain carcinogens that waft through vents, potentially raising cancer risk.

“This is an interesting source of pollution because emissions from dryer vents are essentially unregulated,” said lead author Dr. Anne Steinemann, professor of civil and environmental engineering and of public affairs at the University of Washington, said in a written statement. “If they’re coming out of a smokestack or tail pipe, they’re regulated, but if they’re coming out of a dryer vent, they’re not.”

Previous studies have looked at what chemicals are released by laundry products, since manufacturers don’t have to disclose ingredients used in fragrances or laundry products.

Needless to say, these researchers weren’t thrilled with what they found.

For the study – published in the August issue of Air Quality, Atmosphere and Health – researchers enlisted two homeowners to volunteer their washers and dryers, which the team scrubbed clean beforehand. The researchers ran a regular laundry cycle for three scenarios in each home: once without any detergent, once with a scented liquid laundry detergent, and the last with both scented detergent and a leading brand of scented dryer sheets.

Their analysis found more than 25 “volatile” air pollutants – including the carcinogens acetaldehyde and benzene.

Benzene causes leukemia and other blood cancers, according to the American Cancer Society. Acetaldehyde has been shown to cause nasal and throat cancer in animal studies.

Steinemann thinks agencies focus too much on limiting other pollution sources when they should look closer to home.

“We focus a lot of attention on how to reduce emissions of pollutants from automobiles,” she said. “And here’s one source of pollutants that could be reduced.”

The American Cleaning Institute, however, Steinemann’s study, calling the findings “shoddy science” that didn’t take into account many factors like washing machine brands, different load cycles, and non-scented products.

“Consumers should not be swayed by the sensationalist headlines that may come across the Internet related to this so-called research,” the Institute emailed CBS News.

Men Who Eat Healthy Are More Likely To Attract Romantic Partners

All the more reason to ditch all that red meat.

Men and women go through many rituals to try to attract a mate, whether it’s putting on perfume or cologne, wearing an outfit they feel good in, making a few jokes, or studying up on a subject to try to impress the person they’re interested in.

For men, however, there appears to be one simple thing they can do to get a few dates, and it has nothing to do with whether they’ve got a cool car.

A new study found that women preferred the body odour of men who ate a lot of fruits and vegetables, and were less attracted to men who ate a lot of refined carbohydrates, such as bread and pasta.

“We’ve known for a while that odour is an important component of attractiveness, especially for women,” said study author Ian Stephen of Macquarie University in Australia.

As the researchers note, our sweat can help signal our health status, which plays a role in how we choose a mate, and in how a mate chooses us.

For the study, researchers examined the skin of 43 healthy young men using a spectrophotometer, which uses a light to find carotenoids (pigments from plants) on skin. The idea is if you eat a lot of colourful veggies, the spectrophotometer will be able to detect that colour on your skin.

The men also filled out a survey on their eating habits and then put on a clean shirt and exercised. After they began to sweat, nine women were asked to smell, describe, and rate the shirts.

“We asked the women to rate how much they liked it, how floral, how fruity,” and other descriptors, Stephen explained to NPR, adding, “Women basically found that men who ate more vegetables smelled nicer.”

Women basically found that men who ate more vegetables smelled nicer.

The men who ate a lot of meat didn’t produce a sweat that was any more — or less — attractive to women, but their odour was more intense.

This, albeit small, study seems to back up previous research that shows that smells make a potential mate more attractive.

“Scent and scent communication do play important roles in human sexuality,” Kelly Gildersleeve, a post-doctoral research fellow at Chapman University, told Men’s Journal.

Scent and scent communication do play important roles in human sexuality.

In a 1995 study, researchers found that women preferred the body odours of men whose MHC compositions differed from their own, and while the study didn’t go into what the men ate, it clearly shows a link between body odour and the mating process.

So it can’t hurt to start eating healthier — not only to attract that special someone, but to keep yourself feeling good, too.

An ‘Epidemic’ of Fragranced Products is Affecting Our Health, New Research Suggests

The recent trend for “cleaner,” more natural, unprocessed foods for improved health and well-being has also led to a shift towards household and beauty products that are also more natural and without preservatives, and possibly for good reason.

According to recent research, consumers’ extra attention to what they are putting on their bodies and in their homes could be beneficial for health, with a new study finding that one in three Australians report health problems related to fragranced products.

Professor Anne Steinemann from the University of Melbourne School of Engineering led a survey of a random sample of 1,098 people taken from a large, web-based panel held by Survey Sampling International (SSI).

She found that when exposed to fragranced products, 33 per cent of Australians suffer a variety of adverse health effects, including breathing difficulties, headaches, dizziness, rashes, congestion, seizures, nausea, and a range of other physical problems.

In addition, the results also showed that 7.7 per cent of Australians have lost workdays or a job in the past year due to illnesses caused by exposure to fragranced products in their workplace, and 16.7 per cent want to leave a shop or business as quickly as possible if they smell air fresheners or other fragranced products.

A survey in Australia found that as many as
one in three consumers experience health problems from fragrance.

“This is an epidemic,” said Professor Steinemann commenting on the findings, “Fragranced products are creating health problems across Australia. The effects can be immediate, severe and potentially disabling. But they can also be subtle, and people may not realize they’re being affected.”

Professor Steinemann’s previous research in the U.S. found similar results, revealing that 34.7 per cent of people experience health problems when exposed to fragranced products.

Fragranced products – which can include air fresheners, cleaning products, laundry supplies, and personal care products – give off a range of chemicals including hazardous air pollutants, with Professor Steinemann adding that, “All types of fragranced products tested – even those with claims of ‘green,’ ‘organic,’ and ‘all-natural’-emitted hazardous air pollutants.”

According to Greenbiz, half of all consumer products contain fragrance, and more than 3,000 chemicals can add fragrance to consumer goods worldwide.

Although what product information is required to be disclosed to consumers varies in each country, fragrance ingredients are exempt from full disclosure in any product, not only in the U.S. but also internationally. Often, labeling is vague, with many ingredients just coming under the umbrella of fragrance.

Professor Steinemann’s research will now continue to investigate why fragrance chemicals are causing health problems, and what their effect may be in indoor environments.

The findings can be found published online in the journal Preventive Medicine Reports with more information also available on Professor Steinemann’s own website.

Can People Transmit Happiness by Smell?

Lab experiment with ‘scent samples’ suggests humans pick up on others’ positive emotions via sweat

TUESDAY, May 26, 2015 (HealthDay News) – As emotions go, happiness usually hides in plain sight: seen in a broad smile, heard in a raucous laugh, felt in a big hug.

But new research suggests there may be a less obvious way to pick up on another person’s positive vibes: smell.

According to a team of European researchers, happiness may generate chemicals that get secreted in sweat, and that sweat signal gets sniffed by those around us.

The experiments also suggest that we not only breathe in the upbeat emotions of others, but by doing so we actually become happier ourselves.

“Human sweat produced when a person is happy induces a state similar to happiness in somebody who inhales this odor,” said study co-author Gun Semin, a research professor in the department of psychology at Koc University in Istanbul, Turkey, and the Instituto Superior de Psicologia Aplicada in Lisbon, Portugal.

The findings were published recently in Psychological Science.

The researchers noted that prior research has already demonstrated that negative emotions, such as fear or disgust, can be communicated via odors in sweat.

To see whether the same holds true for the happier feelings, Semin’s team gathered sweat samples from 12 young men after each watched videos designed to induce a variety of emotions, including happiness and fear. All the men were healthy, drug-free nonsmokers, and none drank, consumed smelly foods or engaged in sexual activity during the study period.

In turn, 36 equally healthy young women were engaged to smell the samples while their reactions were monitored. The smell group, explained investigators, was confined to women because women typically have a better sense of smell than men and are also more sensitive to emotional signaling.

After analyzing the facial expressions of the smell group, the research team concluded that there does, in fact, appear to be a so-called “behavioral synchronization” between a sweating person’s emotional state, the sweat generated, and the reaction of the person who sniffs that sweat.

Specifically, that meant that the faces of women who smelled “happy sweat” displayed facial muscle activity deemed to be representative of happiness.

Sweat didn’t always produce a contagious response in the smeller, however. For example, those smellers who verbalized having a “pleasant” or “intense” reaction to a sweat sample did not manifest those reactions in their facial expressions.

What is it exactly that makes “happy sweat” infectious?

Semin, who is also professor of social and behavioral sciences at Utrecht University in the Netherlands, acknowledged that “we have not demonstrated what the nature of the chemical compound is in sweat.”

Pamela Dalton is an olfactory (smell sense) scientist with the Monell Chemical Senses Center in Philadelphia. She said she found the findings “a little surprising.”

However, “what is interesting about this study is that it suggests a positive emotion can be communicated – which in my opinion is far less important in human evolution and behavior than to be able to transmit and recognize a negative emotion, such as fear or anger,” Dalton said.

For that reason, Dalton said she “would expect the ability to communicate a happy emotion to [actually] be less potent than the ability to transmit a negative emotion.”

But Andreas Keller, a research associate with The Rockefeller University in New York City, said the study findings make intuitive sense.

“Hearing happy people and seeing happy people makes you happier,” he said, “so the fact that smelling them would make you happier, too, is probably not so surprising.”

According to Keller, the next step “would be to find out what the chemical difference in fear sweat and happy sweat is that mediates these effects. This would open the door to study what is going on at a mechanistic level.”
