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.
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.
Fluoride Exposure From Infant Formula Lowers IQ
In October 2019, a Canadian study18 concluded that infants fed baby formula made with fluoridated water have lower IQs than those fed formula made with unfluoridated water. As explained by the authors:
Results revealed an increase of 0.5 milligrams of fluoride per liter (mg/L), which was the difference between the fluoridated and non-fluoridated regions, corresponded with a 4.4 point lower IQ score at age 3 to 4.“Consumption of infant formula reconstituted with fluoridated water can lead to excessive intake of fluoride in infants. We examined the association between water fluoride concentration and intellectual ability (IQ) among preschool children who lived in fluoridated or non-fluoridated cities in Canada and were either formula-fed or breastfed during the first six months after birth.”
Not surprisingly, the researchers urge parents to avoid fluoridated water when reconstituting infant formula.
Government-Funded Research Confirms Fluoride Lowers IQ
One of the most recent studies highlighting these dangers was a U.S. and Canadian government-funded observational study published in the August 19, 2019, issue of JAMA Pediatrics,13 which found that drinking fluoridated water during pregnancy lowers children’s IQ.
The research, led by a Canadian team of researchers at York University in Ontario, looked at 512 mother-child pairs living in six Canadian cities. Fluoride levels were measured through urine samples collected during pregnancy.
They also estimated the women’s fluoride consumption based on the level of fluoride in the local water supply and how much water and tea each woman drank. The children’s IQ scores were then assessed between the ages of 3 and 4. As reported by Fluoride Action Network (FAN):14
“They found that a 1 mg per liter increase in concentration of fluoride in mothers’ urine was associated with a 4.5-point decrease in IQ among boys, though not girls.
When the researchers measured fluoride exposure by examining the women’s fluid intake, they found lower IQ’s in both boys and girls: A 1 mg increase per day was associated with a 3.7 point IQ deficit in both genders.”
The findings were deemed so controversial, the study had to undergo additional peer-review and scrutiny before publication, making it one of the more important fluoride studies to date.
Its import is also demonstrated by the fact that it’s accompanied by an editor’s note15 explaining the journal’s decision to publish the study, and a podcast16 featuring the chief editors of JAMA Pediatrics and JAMA Network Open, in which they discuss the study.
An additional editorial17 by David Bellinger, Ph.D., a world-renowned neurotoxicity expert, also points out that “The hypothesis that fluoride is a neurodevelopmental toxicant must now be given serious consideration.” Few studies ever receive all of this added treatment.
