What is silicosis and what does research say about it?

Silicosis is a progressive, debilitating and sometimes fatal lung disease caused by breathing silica dust from cutting, drilling, chipping or grinding materials such as granite, sandstone, slate or artificial stone. The dust gets trapped in the lung tissue, causing inflammation, scarring and permanent damage.
Silicosis is a job-related lung disease and has no cure. The disease mostly affects workers in construction, stone countertop fabrication, mining, and even those who sandblast and stonewash denim jeans to create a ‘worn out’ look.
Silica is one of the most common minerals in nature. About 59% of the Earth’s crust is made of silica, found in quartz, granite, sandstone, slate and sand. Historically, people at the highest risk for the disease have worked in natural environments — mining, digging tunnels or doing quarry work. The disease was first documented by the Greek physician Hippocrates, who in 430 B.C. described breathing disorders in metal diggers.
But in recent decades there’s been renewed attention to the disease due to its more rapid progression and severity among younger workers. Research has shown that the culprit is artificial stone mostly used for countertops for kitchens and bathrooms, which has a very high silica content.
The new generation of coal miners is also at an increased risk of silicosis, in addition to black lung, because layers of coal have become thinner, forcing them to dig deeper into rock, as explained in a joint investigation by the Pittsburgh Post-Gazette and the Medill Investigative Lab at Northwestern University published on Dec. 4. CBS Sunday Morning also had a report on the same issue among West Virginia coal miners, aired as part of its Dec. 10 episode.
Silicosis in modern industries
Artificial, or engineered, stone used for countertops, also known as “quartz,” is formed from finely crushed rocks mixed with resin. Quartz is a natural mineral, but man-made products like many quartz countertops consist of not just quartz, but also resin, colors and other materials that are used to style and strengthen them.
The silica content of artificial stone is about 90%, compared with the 3% silica content of natural marble and 30% silica content in granite stones, according to the authors of a 2019 systematic review published in the International Journal of Environmental Research and Public Health.
The first reported case of silicosis associated with working with artificial stone was from Italy in 2010, according to a 2020 study published in Allergy. Since then, more studies have documented the growing number of cases among artificial stone workers, many of whom are from marginalized populations, such as immigrants.
A July 2023 study published in JAMA Internal Medicine found that in California, the disease mainly occurred among young Latino immigrant men. The disease was severe in most men by the time they sought care.
An August 2022 study, published in Occupational & Environmental Medicine, analyzing the Global Silicosis Registry, with workers in Israel, Spain, Australia and the U.S., found “a substantial emerging population of workers worldwide with severe and irreversible silica-associated diseases,” due to exposure from silica dust from engineered stone.
Other modern occupations such as denim sandblasting, work on dental prostheses, manufacturing of electrical cables and working on jewelry and semi-precious stones also put workers at risk of silicosis.
In the wake of modern-day silicosis cases, researchers have called for larger studies to better understand the disease and the discovery of effective treatments.
In the U.S. about 2.3 million workers are exposed to silica dust on the job, according to the American Lung Association. Other estimates show approximately 10 million workers in India, 3.2 million in the European Union and 2 million in Brazil work with material containing silica.
However, “the reporting system for occupational injuries and illnesses in the United States fails to capture many cases, leading to a poor understanding of silicosis incidence and prevalence,” writes Ryan F. Hoy, who has published extensively on the topic, in a June 2022 article in Respirology.
A 2015 study in the Morbidity & Mortality Weekly Report found the annual number of silicosis deaths declined from 185 people in 1999 to 111 in 2013, but the decline appeared to have leveled off between 2010 and 2013, the authors write. Another 2015 study in MMWR, examining silicosis deaths between 2001 and 2010, found the death rate from silicosis was significantly higher among Black people compared with whites and other races. Men also have a significantly higher death rate from silicosis than women.
The 2019 Global Burden of Disease Study estimates that more than 12,900 people worldwide die from silicosis each year.
Silicosis has no cure, but it’s preventable when workers have access to proper respiratory protection and are educated on safe practices set by regulatory bodies such as the U.S. National Institute for Occupational Safety and Health. The European Network on Silica also has guidelines on handling and using materials containing silica. A March 2023 study published in Environmental Science and Pollution Research International finds that “education, training, and marketing strategies improve respirator use, while training and education motivate workers to use dust control measures.”
Silicosis symptoms and treatment
Symptoms of silicosis include cough, fatigue, shortness of breath and chest pain. There’s no specific test for silicosis. The first signs may show in an abnormal chest X-ray and a slowly developing cough, according to the American Lung Association.
Silicosis symptoms don’t appear right away in most cases, usually taking several years to develop working with silica dust. However, studies indicate that symptoms of silicosis due to exposure to artificial stone appear quicker than exposure to natural silica sources, potentially due to the higher concentration of silica in artificial stone.
There are three types of silicosis: acute (most commonly caused by working with artificial stone), accelerated and chronic, depending on the level of exposure to silica dust, according to the Centers for Disease Control and Prevention, which explains the severity of each type on its website.
Complications from silicosis can include tuberculosis, lung cancer, chronic bronchitis, kidney disease and autoimmune disorders. In some cases, silicosis can cause severe scarring of the lung tissue, leading to a condition called progressive massive fibrosis, or PMF. Some patients may require a lung transplant.
Lung damage from silicosis is irreversible, so treatment of silicosis is aimed at slowing down the disease and relieving its symptoms.
In 1995, the World Health Organization called for the elimination of silicosis by 2030, but research studies and news stories show it remains a threat to many workers.
Below, we have gathered several studies on the topic to help journalists bolster their reporting with academic research.
Research roundup
Artificial Stone Associated Silicosis: A Systematic Review
Veruscka Leso, et al. International Journal of Environmental Research and Public Health, February 2019.
This systematic review aims to verify the association between exposure to silica dust in artificial stone and the development of silicosis.
Researchers narrowed down their selection from 75 papers to seven studies that met their inclusion criteria. The seven studies were from Australia, Israel and Spain. Most of the studies are observational and impede a definite association between exposure to silica while working with artificial stone and developing silicosis, the authors note.
However, “the unusually high incidence of the disease that was reported over short periods of investigations, and the comparable occupational histories of affected workers, all being involved in the manufacture and manipulation of engineered stones, may indicate a cause-effect relationship of this type.”
The review of studies reveals a lack of basic preventive measures such as lack of access to disposable masks; lack of information and training on the dangers of silica dust; and lack of periodic medical examinations, including a chest X-ray, among workers. There was limited environmental monitoring of dust levels at the workplace. Also, there was no dust suppression system, such as the use of water when polishing the stones, or effective ventilation. Machinery and tools weren’t properly set up and didn’t undergo routine checks, the authors write.
The authors recommend environmental monitoring for assessing silica levels in the workplace and verifying the effectiveness of personal protections. They also recommend the health surveillance of workers exposed to silica dust.
“Stakeholders, manufacturers, occupational risk prevention services, insurance companies for occupational accidents and diseases, business owners, occupational health physicians, general practitioners, and also employees should be engaged, not only in designing/planning processes and operational working environments, but also in assessing the global applicability of proactive preventive and protective measures to identify and control crystalline silica exposure, especially in new and unexpected exposure scenarios, the full extent of which cannot yet be accurately predicted,” they write.
Silica-Related Diseases in the Modern World
Ryan F. Hoy and Daniel C. Chambers. Allergy, November 2020.
The study is a review of the mineralogy of silica, epidemiology, clinical and radiological features of the various forms of silicosis and other diseases associated with exposure to silica.
The primary factor associated with the development of silicosis is the intensity and duration of cumulative exposure to silica dust. Most countries regulate silica dust occupational exposure limits, generally in the range of 0.05 mg/m3 to 0.1 mg/m3, although the risk of dust exposure to workers still remains high at those levels.
The study provides a list of activities that could expose workers to silica dust. They include abrasive blasting of sand and sandstone; cement and brick manufacturing; mixing, glazing or sculpting of china, ceramic and pottery; construction involving bricklaying, concrete cutting, paving and demolition; sandblasting denim jeans; working with and polishing dental materials; mining and related milling; handling raw material during paint manufacturing; road and highway construction and repair; soap and cosmetic production; blasting and drilling tunnels; and waste incineration.
“Despite the large number of workers in the construction sector, there have been few studies of [silica dust] exposure in this industry,” the authors note.
Other than silicosis, conditions associated with silica exposure include sarcoidosis, an inflammatory disease that commonly affects the lungs and lymph nodes, autoimmune disease, lung cancer and pulmonary infections.
“Recent outbreaks of silica-associated disease highlight the need for constant vigilance to identify and control new and well-established sources of silica exposure. While there are currently no effective treatments for silicosis, it is a completely preventable lung disease,” the authors write.
A Systematic Review of the Effectiveness of Dust Control Measures Adopted to Reduce Workplace Exposure
Frederick Anlimah, Vinod Gopaldasani, Catherine MacPhail and Brian Davies. Environmental Science and Pollution Research International, March 2023.
This study provides an overview of various interventions and their effectiveness in preventing exposure to silica dust based on a review of 133 studies from 16 countries, including the U.S., Canada, China, India, Taiwan and Australia, and published between 2010 and 2020.
These dust control measures range from simple work practices such as the use of respirators to more sophisticated technologies, such as water and air curtains and foam technology, the authors note.
The review finds increasing research interest in dust reduction, mainly in China. But overall, regulatory influence remains inadequate in preventing miners’ exposure to silica dust.
“Results from the review suggest that adopted interventions increase knowledge, awareness, and attitudes about respirator usage and generate positive perceptions about respirator usage while reducing misconceptions,” the authors write. “Interventions can increase the use, proper use, and frequency of use of respirators and the adoption readiness for dust controls but may not provide sustained motivation in workers for the continual use of dust controls or [personal protective equipment.]”
Notes from the Field: Surveillance of Silicosis Using Electronic Case Reporting — California, December 2022–July 2023
Jennifer Flattery, et al. Morbidity and Mortality Weekly Report, November 2023.
This study examines the use of electronic case reporting to identify silicosis cases in California. Electronic case reporting, or eCR, is the automated, real-time exchange of case report information between electronic health records at health facilities at state and local public health agencies in the U.S. It is a joint effort between the Association of Public Health Laboratories, the Council of State and Territorial Epidemiologists, and the CDC. Currently, 208 health conditions can be reported using eCR. All 50 states and other U.S.-affiliated jurisdictions are connected to eCR. Once a public health agency receives a case report, it reaches out to the patient for contact tracing or other actions.
From October 2022 to July 2023, the California Department of Public Health received initial silicosis case reports for 41 individuals. A review of medical records confirmed 19 cases and 16 probable cases. Six of the 41 cases were considered unlikely to be silicosis after a review of medical records.
Notably, engineered stone countertop fabrication was a significant source of exposure, especially among Hispanic and Latino workers.
At least seven of the 19 confirmed cases were associated with the fabrication of engineered stone — quartz — countertops. The 19 patients’ ages ranged from 33 to 51 and all were Hispanic or Latino. One patient died and two had both lungs replaced. One was evaluated for a lung transplant.
The median age of the 35 patients with probable or confirmed silicosis was 65, ranging from 33 to 89 years, and 91% were men.
“It is important that health care providers routinely ask patients about their work as an important determinant of health,” the authors write. “Being aware of the risks associated with work exposures, as well as the regulations, medical monitoring, and prevention strategies that address those risks can help guide patient care.”

How Much Can Hypnotherapy Really Do?

Sit Back, Relax, And…
In Tuesday’s newsletter, we asked you for your opinions of hypnotherapy, and got the above-depicted, below-described, set of responses:
- About 58% said “It is a good, evidenced-based practice that can help alleviate many conditions”
- Exactly 25% said “It is a scam and sham and/or wishful thinking at best, and should be avoided by all”
- About 13% said “It works only for those who are particularly suggestible—but it does work for them”
- One (1) person said “It is useful only for brain-centric conditions e.g. addictions, anxiety, phobias, etc”
So what does the science say?
Hypnotherapy is all in the patient’s head: True or False?
True! But guess which part of your body controls much of the rest of it.
So while hypnotherapy may be “all in the head”, its effects are not.
Since placebo effect, nocebo effect, and psychosomatic effect in general are well-documented, it’s quite safe to say at the very least that hypnotherapy thus “may be useful”.
Which prompts the question…
Hypnotherapy is just placebo: True or False?
False, probably. At the very least, if it’s placebo, it’s an unusually effective placebo.
And yes, even though testing against placebo is considered a good method of doing randomized controlled trials, some placebos are definitely better than others. If a placebo starts giving results much better than other placebos, is it still a placebo? Possibly a philosophical question whose answer may be rooted in semantics, but happily we do have a more useful answer…
Here’s an interesting paper which: a) begins its abstract with the strong, unequivocal statement “Hypnosis has proven clinical utility”, and b) goes on to examine the changes in neural activity during hypnosis:
Brain Activity and Functional Connectivity Associated with Hypnosis
It works only for the very suggestible: True or False?
False, broadly. As with any medical and/or therapeutic procedure, a patient’s expectations can affect the treatment outcome.
And, especially worthy of note, a patient’s level of engagement will vastly affect it treatment that has patient involvement. So for example, if a doctor prescribes a patient pills, which the patient does not think will work, so the patient takes them intermittently, because they’re slow to get the prescription refilled, etc, then surprise, the pills won’t get as good results (since they’re often not being taken).
How this plays out in hypnotherapy: because hypnotherapy is a guided process, part of its efficacy relies on the patient following instructions. If the hypnotherapist guides the patient’s mind, and internally the patient is just going “nope nope nope, what a lot of rubbish” then of course it will not work, just like if you ask for directions in the street and then ignore them, you won’t get to where you want to be.
For those who didn’t click on the above link by the way, you might want to go back and have a look at it, because it included groups of individuals with “high/low hypnotizability” per several ways of scoring such.
It works only for brain-centric things, e.g. addictions, anxieties, phobias, etc: True or False?
False—but it is better at those. Here for example is the UK’s Royal College of Psychiatrists’ information page, and if you go to “What conditions can hypnotherapy help to treat”, you’ll see two broad categories; the first is almost entirely brain-stuff; the second is more varied, and includes pain relief of various kinds, burn care, cancer treatment side effects, and even menopause symptoms. Finally, warts and other various skin conditions get their own (positive) mention, per “this is possible through the positive effects hypnosis has on the immune system”:

Cross That Bridge – by Samuel J. Lucas
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Books of this genre usually have several chapters of fluff before getting to the point. You know the sort:
- Let me tell you about some cherry-picked celebrity stories that overlook survivorship bias
- Let me tell you my life story, the bad parts
- My life story continued, the good parts now
- What this book can do for you, an imaginative pep talk that keeps circling back to me
…then there will be two or three chapters of the actual advertised content, and then a closing chapter that’s another pep talk.
This book, in contrast, throws that out of the window. Instead, Lucas provides a ground-up structure… within which, he makes a point of giving value in each section:
- exercises
- summaries
- actionable advice
For those who like outlines, lists, and overviews (as we do!), this is perfect. There are also plenty of exercises to do, so for those who like exercises, this book will be great too!
Caveat: occasionally, the book’s actionable advices are direct but unclear, for example:
- Use the potential and power of tea, to solve problems
Context: there was no context. This was a bullet-pointed item, with no explanation. It was not a callback to anything earlier; this is the first (and only) reference to tea.
However! The book as a whole is a treasure trove of genuine tips, tools, and voice-of-experience wisdom. Occasional comments may leave you scratching your head, but if you take value from the rest, then the book was already more than worth its while.

Ageless – by Dr. Andrew Steele
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
So, yet another book with “The new science of…” in the title; does this one deliver new science?
Actually, yes, this time! The author was originally a physicist before deciding that aging was the number one problem that needed solving, and switched tracks to computational biology, and pioneered a lot of research, some of the fruits of which can be found in this book, in amongst a more general history of the (very young!) field of biogerontology.
Downside: most of this is not very practical for the lay reader; most of it is explanations of how things happen on a cellular and/or genetic level, and how we learned that. A lot also pertains to what we can learn from animals that either age very slowly, or are biologically immortal (in other words, they can still be killed, but they don’t age and won’t die of anything age-related), or are immune to cancer—and how we might borrow those genes for gene therapy.
However, there are also chapters on such things as “running repairs”, “reprogramming aging”, and “how to live long enough to live even longer”.
The style is conversational pop science; in the prose, he simply states things without reference, but at the back, there are 40 pages of bibliography, indexed in the order in which they occurred and prefaced with the statement that he’s referencing in each case. It’s an odd way to do citations, but it works comfortably enough.
Bottom line: if you’d like to understand aging on the cellular level, and how we know what we know and what the likely future possibilities are, then this is a great book; it’s also simply very enjoyable to read, assuming you have an interest in the topic (as this reviewer does).

Planning Ahead For Better Sleep

Sleep: 6 Dimensions And 24 Hours!
This is Dr. Lisa Matricciani, a sleep specialist from the University of South Australia, where she teaches in the School of Health Sciences.
What does she want us to know?
Healthy sleep begins before breakfast
The perfect bedtime routine is all well and good, but we need to begin much earlier in the day, Dr. Matricciani advises.
Specifically, moderate to vigorous activity early in the day plays a big part.
Before breakfast is best, but even midday/afternoon exercise is associated with better sleep at night.
Read more: Daytime Physical Activity is Key to Unlocking Better Sleep
Plan your time well to sleep—but watch out!
Dr. Matricciani’s research has also found that while it’s important to plan around getting a good night’s sleep (including planning when this will happen), allocating too much time for sleep results in more restless sleep:
❝Allocating more time to sleep was associated with earlier sleep onsets, later sleep offsets, less efficient and more consistent sleep patterns for both children and adults.❞

It is not! Although that’s one part of it. You may remember our previous main feature:
The 6 Dimensions Of Sleep (And Why They Matter)
Dr. Matricciani agrees:
❝Everyone knows that sleep is important. But when we think about sleep, we mainly focus on how many hours of sleep we get, when we should also be looking at our sleep experience as a whole❞

Chocolate & Health
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Chocolate & Health: Fact or Fiction?
“Chocolate Is Good For The Heart”
“When making chocolate chip cookies, you don’t measure using cups, you measure by heart”
…but how good is chocolate when it comes to heart health?
First, what is heart health?
A healthy heart typically has a low resting pulse rate and a strong, steady beat. This is affected strongly by exercise habits, and diet plays only a support role (can’t exercise without energy from food!).
It is also important to have blood pressure within a healthy range (with high blood pressure being a more common problem than low, so things that lower blood pressure are generally considered good).
- Flavanols, flavonoids, and polyphenols in chocolate contribute to lower blood pressure
- Dark chocolate is best for these, as milk chocolate contains much less cocoa solids and more unhelpful fats
- White chocolate contains no cocoa solids and is useless for this
- Some of the fats in most commercial chocolate can contribute to atherosclerosis which raises blood pressure and ultimately can cause heart attacks.
- If you’re diabetic, you will probably not get the usual heart-related benefits from chocolate (sorry)
The Verdict: dark chocolate, in moderation, can support good heart health.
“Chocolate Is Good For The Brain”
Chocolate has been considered a “brain food”… why?
- The brain uses more calories than any other organ (chocolate has many calories)
- The heart benefits we listed above mean improved blood flow—including to your brain
- Chocolate contains phenylethylamine, a powerful chemical that has a similar effect to amphetamines… But it’s metabolized in digestion and never makes it to the central nervous system (so basically, this one’s a miss; we had a good run with the other two, though!)
The Verdict: dark chocolate, in moderation, can support good brain health
“Chocolate Is An Aphrodisiac”
“If chocolate be the food of love, pass me that cocoa; I’m starving”
Most excitingly, chocolate contains phenylethylamine, the “molecule of love” or, more accurately, lust. It has an effect similar to amphetamines, and while we can synthesize it in the body, we can also get it from certain foods. But…
Our body is so keen to get it that most of it is metabolized directly during digestion and doesn’t make it to the brain. Also, chocolate is not as good a source as cabbage—do with that information what you will!
However!
Chocolate contains theobromine and small amounts of caffeine, both stimulants and both generally likely to improve mood; it also contains flavonoids which in turn stimulate production of nitric oxide, which is a relaxant. All in all, things that are convivial to having a good time.
On the other hand…
That relaxation comes specifically with a reduction in blood pressure—something typically considered good for the health for most people most of the time… but that means lowering blood pressure in all parts of your body, which could be the opposite of what you want in intimate moments.
Chocolate also contains zinc, which is essential for hormonal health for most people—the body uses it to produce testosterone and estrogen, respectively. Zinc supplements are popularly sold to those wishing to have more energy in general and good hormonal health in particular, and rightly so. However…
This approach requires long-term supplementation—you can’t just pop a zinc tablet / bar of chocolate / almond before bed and expect immediate results. And if your daily zinc supplementation takes the form of a 3.5oz (100g) bar of chocolate, then you may find it has more effects on your health, and not all of them good!
The Verdict: dark chocolate, in moderation, may promote “the mood”, but could be a double-edged sword when it comes to “the ability”.
“Chocolate Is Good During Menstruation”
The popular wisdom goes that chocolate is rich in iron (of which more is needed during menstruation), and indeed, if you eat 7oz (150g) of dark chocolate made with 85% cocoa, you’ll get a daily a dose of iron (…and nearly 1,000 calories).
More bang-for-buck dietary sources of iron include chickpeas and broccoli, but for some mysterious reason, these are not as commonly reported as popular cravings.
The real explanation for chocolate cravings is more likely that eating chocolate—a food high in sugar and fat along with a chemical bombardment of more specialized “hey, it’s OK, you can relax now” molecules (flavanols/flavonoids, polyphenols, phenylamines, even phenylethylamine, etc) gives a simultaneous dopamine kick (the body’s main “reward” chemical) with a whole-body physiological relaxation… so, little wonder we might crave it in times of stress and discomfort!
The Verdict: it helps, not because it serves a special nutritional purpose, but rather, because the experience of eating chocolate makes us feel good.
Fun fact: Tiramisu (this writer’s favorite dessert) is literally Italian for “pick-me-up”

Cherries vs Grapes – Which is Healthier?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Our Verdict
When comparing cherries to grapes, we picked the cherries.
Why?
First, let’s mention: we are looking at sour cherries and Californian grapes. Even those will of course vary in quality, but the nutritional values here are quite reliable averages.
In terms of macros you might have guessed this one: cherries have nearly 2x the fiber and grapes have about 50% more carbs. So, while neither fruit is bad and they are both low glycemic index foods, cherry is the winner in this category.
When it comes to vitamins, cherries have more of vitamins A, B3, B5, B9, C, and choline, while grapes have more of vitamins B1, B2, B6, E, and K. That’s a 6:5 win for cherries, and the respective margins of difference bear that out too.
In the category of minerals, cherries have more calcium, copper, iron, magnesium, phosphorus, and zinc, while grapes have more manganese and potassium. An easy 6:2 win for cherries.
You might be wondering about polyphenols: both are very abundant in very many polyphenols; so much and so many, in fact, that we couldn’t possibly try to adjudicate between them without doing some complex statistical modeling (especially given how much this can vary from one sample to another, much more so than the micro-and macronutrient values discussed above), so we’ll call it a tie on these.
Adding up the section makes for a clear win for cherries, but of course, enjoy either or both!
