Common hair products linked to cancer risk, says breaking new study
Embracing signs of age might be the road to a longer life after all.
- New research found that hair dyes and chemical straighteners might significantly increase the risk of breast cancer.
- According to the study, black women who used permanent dyes at least every 5-8 weeks raised their risk of developing cancer by 60 percent.
- This isn't the first time beauty products have been found to contain cancerous chemicals.
Earlier this week, a disturbing report came out showing that permanent hair dye is heavily associated with cancer risk.
In a study published in the Journal of Cancer, findings show that hair dyes and chemical straighteners might significantly increase the risk of breast cancer. This is because they contain hormone-disrupting compounds and carcinogens that might be connected to the development of breast cancer, particularly in black women.
The link between hair products and cancer
While the link between breast cancer and permanent hair dye has been hypothesized in the past, prior findings had been inconclusive until now.
This new study looked at 46,709 women living in the United States between the ages of 35 and 74 between 2003 and 2009. Although none of the participants had breast cancer at the beginning of the study, all had at least one sister who had breast cancer and were, therefore, at elevated risk. Over the course of the study, 2,794 breast cancers were identified in the participants.
One of the most disturbing elements of the study was the stark contrast between the elevated risk of cancer between black women and white women who permanently dyed their hair. While past research on hair dye use and breast cancer risk had largely been limited to white women, this study found that black women who used permanent dyes at least every 5-8 weeks raised their risk of developing cancer by a shocking 60 percent compared to those who didn't. White women, on the other hand, raised their risk by only 8 percent. This might be because, as previous studies have shown, hair products that are designed for use by black women may contain more endocrine‐disrupting chemicals.
Additionally, women who used chemical straighteners at least every 5-8 weeks were 30 percent more likely to develop breast cancer. This was a cosmetic practice more commonly used by black women. The study found that 74 percent of black women had used chemical straighteners as opposed to 3 percent of white women. The researchers suggest that this could be because the treatment uses a concoction of chemicals that might include formaldehyde—a known carcinogen—as an active ingredient.
What the experts are saying
It's been estimated that more than a third of women past the age of 18 in the United States use hair dye. And hair products contain more than 5,000 chemicals, including some with properties that may disrupt hormones and cause genetic mutations.
Robin Dodson, a research scientist who studies environmental risks to women's health at the Silent Spring Institute, told The New York Times that most products that are on the market today are not sufficiently tested for safety, and that they aren't tested for additives that may disrupt the body's hormone production. Specifically, she's identified chemicals that imitate estrogen, which can fuel some types of breast cancer, in hair straighteners used more often by black women.
One of the authors of the study noted to the Times that the risks of dye use are still relatively small. Although the findings were more concerning for black women, this demographic only made up 9 percent of the study's participants, which is too small a sample size to know how real the risks are.
Embracing age to live longer
Ironically, adhering to certain values and beliefs that idolize youth may end up causing fatal illnesses that shorten life. Could the path of least resistance when it comes to signs of age be the road to longevity?
Fortunately, thanks in part to recent challenges to conventional beauty standards that have long fetishized youth, grey hair is trending right now. Take, for instance, Instagram accounts like @grombre, which celebrates women showing off their fresh new silver strands. Since embracing signs of added years rams into some deeply rooted cultural ideas about beauty and age, there's been a proliferation of online support groups and how-to blogs for women trying to transfer to an au naturale grey head of hair.
This isn't the first time beauty products have been found to contain cancerous chemicals. Back in 2015 a worrying report by the Breast Cancer Fund's Campaign for Safe Cosmetics found that some popular anti-aging creams use an ingredient called PFOA, a chemical linked to cancer and endocrine disruption.
There's a cultural irony at hand: Are certain markers of a youthful appearance worth more than actual years of life? Fighting the aging process is expensive, energy draining, time consuming, and arguably futile. Maybe it's time we prioritize the living part of life, rather than looking like we've lived less of it.
Innovation in manufacturing has crawled since the 1950s. That's about to speed up.
Why do so many people encounter beings after smoking large doses of DMT?
- DMT is arguably the most powerful psychedelic drug on the planet, capable of producing intense hallucinations.
- Researchers recently surveyed more than 2,000 DMT users about their encounters with 'entities' while tripping, finding that respondents often considered these strange encounters to be positive and meaningful.
- The majority of respondents believed the beings they encountered were not hallucinations.
What are DMT beings?<p>Do DMT entities actually exist in some other dimension, or are they hallucinations that the brain generates when its visual processing system is overwhelmed by a powerful tryptamine?<br></p><p>The late American ethnobotanist Terence McKenna believed that DMT beings — which he called "machine elves" — were real. Here's how he once <a href="https://www.ranker.com/list/dmt-machine-elves-facts/inigo-gonzalez" target="_blank">described</a> one of his DMT experiences:</p><p style="margin-left: 20px;">"I sank to the floor. I [experienced] this hallucination of tumbling forward into these fractal geometric spaces made of light and then I found myself in the equivalent of the Pope's private chapel and there were insect elf machines proffering strange little tablets with strange writing on them, and I was aghast, completely appalled, because [in] a matter of seconds... my entire expectation of the nature of the world was just being shredded in front of me. I've never actually gotten over it.</p><p style="margin-left: 20px;">These self-transforming machine elf creatures were speaking in a colored language which condensed into rotating machines that were like Fabergé eggs but crafted out of luminescent superconducting ceramics and liquid crystal gels. All this stuff was just so weird and so alien and so un-English-able that it was a complete shock — I mean, the literal turning inside out of [my] intellectual universe!"</p><p>McKenna believed machine elves exist in alternate realities, which form a "<a href="https://www.irishtimes.com/culture/books/old-favourites-the-archaic-revival-1991-by-terence-mckenna-1.3924887" target="_blank">raging universe of active intelligence that is transhuman, hyperdimensional, and extremely alien.</a>" But he was far from the first to believe that DMT is a doorway to other realms.</p><p>Indigenous peoples of the Amazon basin have used ayahuasca in religious ceremonies for centuries, though no one is quite sure when they first started experimenting with the psychedelic brew. The Jibaro people of the Ecuadorian rainforest believed ayahuasca allowed regular people, not just shamans, to <a href="https://atrium.lib.uoguelph.ca/xmlui/bitstream/handle/10214/17902/RichardsonG_202004_HonThesis.pdf?sequence=3" target="_blank">speak directly to the gods</a>. The 19th-century Ecuadorian geographer Villavicencio wrote of other Amazonian shamans who used ahaysuca (known as the "vine of the dead") to contact spirits and foresee enemy battle plans.</p><p>In the West, research on DMT experiences has been sparse yet interesting. The psychiatrist Rick Strassman conducted some of the first human DMT trials at the University of New Mexico in the early 1990s. He found that <a href="https://www.erowid.org/chemicals/dmt/dmt_article3.shtml" target="_blank">"at least half"</a> of his research subjects had encountered some form of entity after taking DMT.</p><p style="margin-left: 20px;">"I was neither intellectually nor emotionally prepared for the frequency with which contact with beings occurred in our studies, nor the often utterly bizarre nature of these experiences," Strassman wrote in his book "DMT The Spirit Molecule".</p>
Manuel Medir / Getty<p style="margin-left: 20px;">"Whenever I tried to pull any information out of the entities regarding themselves, the data that was given up was always relevant only to me. The elves could not give me any piece of data I did not already know, nor could their existence be sustained under any kind of prolonged scrutiny."</p><p>It's also worth noting that not all people who smoke DMT see beings, and that some see beings that look <a href="https://www.erowid.org/chemicals/dmt/dmt_article3.shtml" target="_blank">nothing like elves or aliens</a>. The diversity of these reports seems to count against the argument that DMT beings exist in some objective alternate reality.</p><p>In other words, if DMT beings exist in some other dimension, shouldn't they appear the same to anyone who visits that dimension? Or do the beings assume a different appearance based on who's looking? Or are there many types of beings in the DMT universe, but most look like elves? </p><p>You might start seeing elves just trying to sort this stuff out.</p><p>Ultimately, nobody knows exactly why DMT beings take the forms they do, or whether they're just figments of overstimulated imaginations. And the answers might be beside the point. </p><p>In the recent survey, 60 percent of participants said their encounter with DMT beings "produced a desirable alteration in their conception of reality whereas only 1% indicated an undesirable alteration in their conception of reality."</p><p>DMT beings may be nothing more than projections of the subconscious mind. But these bizarre encounters do help some people find real meaning, whether it's through personal revelation or the raw power of ontological shock.</p>
So far, 30 student teams have entered the Indy Autonomous Challenge, scheduled for October 2021.
- The Indy Autonomous Challenge will task student teams with developing self-driving software for race cars.
- The competition requires cars to complete 20 laps within 25 minutes, meaning cars would need to average about 110 mph.
- The organizers say they hope to advance the field of driverless cars and "inspire the next generation of STEM talent."
Indy Autonomous Challenge<p>Completing the race in 25 minutes means the cars will need to average about 110 miles per hour. So, while the race may end up being a bit slower than a typical Indy 500 competition, in which winners average speeds of over 160 mph, it's still set to be the fastest autonomous race featuring full-size cars.</p><p style="margin-left: 20px;">"There is no human redundancy there," Matt Peak, managing director for Energy Systems Network, a nonprofit that develops technology for the automation and energy sectors, told the <a href="https://www.post-gazette.com/business/tech-news/2020/06/01/Indy-Autonomous-Challenge-Indy-500-Indianapolis-Motor-Speedway-Ansys-Aptiv-self-driving-cars/stories/202005280137" target="_blank">Pittsburgh Post-Gazette</a>.

But that prize went unclaimed, because within a few hours after starting, all the vehicles had suffered some kind of critical failure.</p>

Indy Autonomous Challenge<p>One factor that could prevent a similar outcome in the upcoming race is the ability to test-run cars on a virtual racetrack.

"We can use that to train the AI, so it starts to come up to speed."</p><p>Still, the race could reveal that self-driving cars aren't quite ready to race at speeds of over 110 mph.

A new Harvard study finds that the language you use affects patient outcome.
- A study at Harvard's McLean Hospital claims that using the language of chemical imbalances worsens patient outcomes.
- Though psychiatry has largely abandoned DSM categories, professor Joseph E Davis writes that the field continues to strive for a "brain-based diagnostic system."
- Chemical explanations of mental health appear to benefit pharmaceutical companies far more than patients.
Challenging the Chemical Imbalance Theory of Mental Disorders: Robert Whitaker, Journalist<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="41699c8c2cb2aee9271a36646e0bee7d"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/-8BDC7i8Yyw?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>This is a far cry from Howard Rusk's 1947 NY Times editorial calling for mental healt</p><p>h disorders to be treated similarly to physical disease (such as diabetes and cancer). This mindset—not attributable to Rusk alone; he was merely relaying the psychiatric currency of the time—has dominated the field for decades: mental anguish is a genetic and/or chemical-deficiency disorder that must be treated pharmacologically.</p><p>Even as psychiatry untethered from DSM categories, the field still used chemistry to validate its existence. Psychotherapy, arguably the most efficient means for managing much of our anxiety and depression, is time- and labor-intensive. Counseling requires an empathetic and wizened ear to guide the patient to do the work. Ingesting a pill to do that work for you is more seductive, and easier. As Davis writes, even though the industry abandoned the DSM, it continues to strive for a "brain-based diagnostic system." </p><p>That language has infiltrated public consciousness. The team at McLean surveyed 279 patients seeking acute treatment for depression. As they note, the causes of psychological distress have constantly shifted over the millennia: humoral imbalance in the ancient world; spiritual possession in medieval times; early childhood experiences around the time of Freud; maladaptive thought patterns dominant in the latter half of last century. While the team found that psychosocial explanations remain popular, biogenetic explanations (such as the chemical imbalance theory) are becoming more prominent. </p><p>Interestingly, the 80 people Davis interviewed for his book predominantly relied on biogenetic explanations. Instead of doctors diagnosing patients, as you might expect, they increasingly serve to confirm what patients come in suspecting. Patients arrive at medical offices confident in their self-diagnoses. They believe a pill is the best course of treatment, largely because they saw an advertisement or listened to a friend. Doctors too often oblige without further curiosity as to the reasons for their distress. </p>
Image: Illustration Forest / Shutterstock<p>While medicalizing mental health softens the stigma of depression—if a disorder is inheritable, it was never really your fault—it also disempowers the patient. The team at McLean writes,</p><p style="margin-left: 20px;">"More recent studies indicate that participants who are told that their depression is caused by a chemical imbalance or genetic abnormality expect to have depression for a longer period, report more depressive symptoms, and feel they have less control over their negative emotions."</p><p>Davis points out the language used by direct-to-consumer advertising prevalent in America. Doctors, media, and advertising agencies converge around common messages, such as everyday blues is a "real medical condition," everyone is susceptible to clinical depression, and drugs correct underlying somatic conditions that you never consciously control. He continues,</p><p style="margin-left: 20px;">"Your inner life and evaluative stance are of marginal, if any, relevance; counseling or psychotherapy aimed at self-insight would serve little purpose." </p><p>The McLean team discovered a similar phenomenon: patients expect little from psychotherapy and a lot from pills. When depression is treated as the result of an internal and immutable essence instead of environmental conditions, behavioral changes are not expected to make much difference. Chemistry rules the popular imagination.</p>
