(TMU) — Fluoride exposure may be associated with changes in the pineal gland which affect sleep cycle regulation among older adolescents, according to new research from the Icahn School of Medicine at Mount Sinai. Another study published in the journal Environment International found that exposing infants to increasing levels of fluoride in tap water may result in diminished non-verbal intellectual abilities, with a stronger effect found among formula-fed children.

These two studies are only the latest research produced in recent years which call into question the safety of water fluoridation.

The Mount Sinai team examined data from the National Health and Nutrition Examination Survey looking for adolescents who had measurable amounts of fluoride in their water and plasma. The researchers were investigating the relationships between fluoride exposure and self-reported sleep patterns. The researchers state that their study is the first to explore the connection between fluoride and sleep patterns in humans or animals. A sample of adolescents at an average age of 17 who live in the United States was used for the study due to the nation’s water fluoridation program.

While fluoride has been regarded as a major public health achievement, the toxin accumulates in the pineal gland where melatonin is produced, according to the researchers. Melatonin is the hormone responsible for regulating the sleep-wake cycle.

The high accumulation of fluoride in pineal gland hydroxyapatite (among those chronically exposed) points to a plausible mechanism by which fluoride may influence sleep patterns. In adults, pineal gland fluoride concentrations have been shown to strongly correlate with degree of pineal gland calcification,” explained the authors. “Interestingly, greater degree of pineal calcification among older adolescents and/or adults is associated with decreased melatonin production, lower REM sleep percentage, decreased total sleep time, poorer sleep efficiency, greater sleep disturbances and greater daytime tiredness.

The study also found that water fluoride concentrations were associated with higher odds of reports of snorting, gasping, or stopping breathing while sleeping at night. The higher water fluoride concentrations may be associated with frequent daytime sleepiness as well as an association with a later bedtime by 24 minutes and a later morning wake time by 26 minutes.

Our findings also showed that fluoride exposure may be associated with shifts in the sleep-wake cycle, as higher water fluoride concentrations were associated with later weekday bedtime and wake time, but not sleep duration,” the researchers explain in Environmental Health. The researchers caution that additional studies must to be conducted “in order to investigate the effects of fluoride on sleep patterns and to identify windows of vulnerability for potential effects.

Meanwhile, another team of researchers published the study Fluoride exposure from infant formula and child IQ in a Canadian birth cohort,” examining the association between fluoride exposure in infancy and intellectual ability in children who lived in fluoridated or non-fluoridated cities in Canada. The researchers note that infants who consume formula reconstituted with fluoridated water are likely to have an excessive fluoride intake while breastfed infants tend to receive a very low intake of fluoride.

The team compared IQ scores in 398 children who were formula-fed versus those who were breastfed during infancy. They found thatIQ scores were lower with higher levels of fluoride in tap water and the effects were “more pronounced among formula-fed children, especially for nonverbal skills.” In an earlier version of the study the researchers concluded, “These findings indicate the possible need to reduce fluoride intake during pregnancy.

This study is not the first to identify an association between exposure to fluoride and lower IQ in children.

In 2012, researchers from Harvard School of Public Health (HSPH) and China Medical University in Shenyang published a meta-analysis in Environmental Health Perspectives which found strong indications that fluoride may adversely affect cognitive development in children. The authors warned that this risk should not be ignored and that more research on fluoride’s impact on the developing brain is necessary. 

The Mind Unleashed will continue to monitor future findings on the health impacts of fluoride.

Background: What is Fluoride?

The substances added to municipal water supplies known by the name fluoride are actually a combination of unpurified byproducts of phosphate mining, namely hydrofluorosilicic acid, sodium fluorosilicate, and sodium fluoride. In the United States, thousands of tons of fluorosilicic acid is recovered from phosphoric acid plants and then used for water fluoridation. During this process the fluoride ion is created.

This process of taking waste from the phosphate industry and putting it into drinking water has long been criticized for its effects on human health and that of the environment. It is well known that water fluoridation has led to dental fluorosis for millions of children. This discoloring of the teeth was called “cosmetically objectionable” by the Centers for Disease Control. But beyond the cosmetic effect there have been a number of studies indicating health issues ranging from arthritisbrain problemsreduced thyroid or overactive  thyroidkidney problems, and bone cancers.

While proponents of water fluoridation have long pointed to an apparent drop in tooth decay in fluoridated nations as proof of its validity, those claims have been proven wrong by the World Health Organization (WHO). While the Center for Disease Control and Prevention has stated the fluoride in the water is directly related to better teeth quality, the WHO released its own study showing that tooth decay rates have dropped in all western nations, whether water is fluoridated or not.

The reasons for opposing water fluoridation include: fear of a variety of health concerns; the belief that it is forcibly medicating the population without their approval; financial waste; and environmental concerns related to phosphate mines where the chemical is found.

Biden to Ban Menthol Cigarettes, Citing Health Impact on Youth and Black People

The Biden administration is reportedly planning to propose an immediate ban on menthol cigarettes, a product that has long been targeted by anti-smoking advocates and critics who claim that the tobacco industry has aggressively marketed to Black people in the U.S.

On Wednesday, the Washington Post reported that the administration could announce a ban on menthol and other flavored cigarettes as soon as this week.

Roughly 85 percent of Black smokers use such menthol brands as Newport and Kool, according to the Food and Drug Administration. Research has also found that menthol cigarettes are easier to become addicted to and harder to quit than unflavored tobacco products, along with other small cigars popular with young people and African Americans.

Civil rights advocates claim that the decision should be greeted by Black communities and people of color who have been marketed to by what they describe as the predatory tobacco industry.

Black smokers generally smoke far less than white smokers, but suffer a disproportionate amount of deaths due to tobacco-linked diseases like heart attack, stroke, and other causes.

Anti-smoking advocates like Matthew L. Myers, president of Campaign for Tobacco-Free Kids, also greeted the move to cut out products that appeal to children and young adults.

“Menthol cigarettes are the No. 1 cause of youth smoking in the United States,” he said. “Eliminating menthol cigarettes and flavored cigars used by so many kids will do more in the long run to reduce tobacco-related disease than any action the federal government has ever taken.”

However, groups including the American Civil Liberties Group (ACLU) has opposed the move, citing the likelihood that such an action could lead to criminal penalties arising from the enforcement of a ban hitting communities of color hardest.

In a letter to administration officials, the ACLU and other groups including the Drug Policy Alliance said that while the ban is “no doubt well-intentioned” it would also have “serious racial justice implications.”

“Such a ban will trigger criminal penalties, which will disproportionately impact people of color, as well as prioritize criminalization over public health and harm reduction,” the letter explained. “A ban will also lead to unconstitutional policing and other negative interactions with local law enforcement.”

Pollution Is Making Human Penises Shrink and Causing a Collapse of Fertility, Scientists Say

With many still scoffing at the idea of rampant pollution posing a threat to humanity, a new study could drastically change the conversation: the chemicals across our environment could be the cause of shrinking human penises.

According to a new book by Dr. Shanna H. Swan, conditions in the modern world are quickly altering the reproductive development of humans and posing a threat to our future as a species.

The argument is laid out in her new book Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race.

The book discusses how pollution is not only leading to skyrocketing erectile dysfunction rates and fertility decline, but also an expansion in the number of babies born with small penises.

While it may seem like good fodder for jokes, the research could portend a grim future for humanity’s ability to survive.

Swan co-authored a study in 2017 that found sperm counts had precipitously fallen in Western countries by 59 percent between 1973 and 2011. In her latest book, Swan blames chemicals for this crisis in the making.

“Chemicals in our environment and unhealthy lifestyle practices in our modern world are disrupting our hormonal balance, causing various degrees of reproductive havoc,” she wrote in the new book.

“In some parts of the world, the average twentysomething woman today is less fertile than her grandmother was at 35,” she also wrote, noting that men could have only half the sperm count of their grandfathers.

Swan blames the disruption on phthalates, the chemicals used in plastic manufacturing that also have an impact on how the crucial hormone endocrine is produced

However, experts note that the proper implementation of pollution reduction measures could help humanity prevent the collapse of human fertility.

Visualizing The World’s Deadliest Pandemics By Population Impact

Humanity has been battling against disease for centuries.

And while most contagious outbreaks have never reached full-blown pandemic status, Visual Capitalist’s Carmen Ang notes that there have been several times throughout history when a disease has caused mass devastation.

Here’s a look at the world’s deadliest pandemics to date, viewed from the lens of the impact they had on the global population at the time.

Editor’s note: The above graphic was created in response to a popular request from users after viewing our popular history of pandemics infographic initially released a year ago.

Death Toll, by Percent of Population

In the mid-1300s, a plague known as the Black Death claimed the lives of roughly 200 million people – more than 50% of the global population at that time.

Here’s how the death toll by population stacks up for other significant pandemics, including COVID-19 so far.

The specific cause of the Black Death is still up for debate. Many experts claim the 14th-century pandemic was caused by a bubonic plague, meaning there was no human-to-human transmission, while others argue it was possibly pneumonic.

Interestingly, the plague still exists today – however, it’s significantly less deadly, thanks to modern antibiotics.

History Repeats, But at Least We Keep Learning

While we clearly haven’t eradicated infection diseases from our lives entirely, we’ve at least come a long way in our understanding of what causes illness in the first place.

In ancient times, people believed gods and spirits caused diseases and widespread destruction. But by the 19th century, a scientist named Louis Pasteur (based on findings by Robert Koch) discovered germ theory – the idea that small organisms caused disease.

What will we discover next, and how will it impact our response to disease in the future?
