James (Swift), you might be interested to learn that there is not one mention of the word"chakra" or other new age nonsense in this serious academic paper entitled “The effect of fluoride on the physiology of the pineal gland” from this dissertation for the School of Biological Sciences, University of Surrey.
The pineal gland is important in the production of melatonin (which is essential for proper sleep function, for example, and the regulation of other bodily organs). The paper above references quite a long list of other related studies.
The conclusion made in that particular paper:
“In conclusion, the human pineal gland contains the highest concentration of fluoride in the body. Fluoride is associated with depressed pineal melatonin synthesis by prepubertal gerbils and an accelerated onset of sexual maturation in the female gerbil. The results strengthen the hypothesis that the pineal has a role in the timing of the onset of puberty. Whether or not fluoride interferes with pineal function in humans requires further investigation.”
ie. Fluoride accumulated in the human pineal gland (which is not debated) interferes with functions in a way that we are not 100% sure of and has been demonstrated to at least cause the effects listed above in tested animals.
The National Sleep Foundation in the USA, which according to The National Institute of Neurological Disorders and Stroke is “a national nonprofit organization that works to improve public health and safety by promoting public understanding of sleep and sleep disorders. Supports sleep-related education, research, and advocacy; produces and distributes educational materials to the public and healthcare professionals; and offers postdoctoral fellowships and grants for sleep researchers.”
The National Sleep Foundation recognises the pineal gland as the part of the body that produces the hormone melatonin which aids healthy sleep and suggests that an imbalance can lead to disorders and even talks about a link with melatonin levels and an increased risk of type 2 diabetes.

“Some studies show that the degree of pineal gland calcification is significantly higher in patients with Alzheimer’s disease vs. other types of dementia. Pineal gland calcification may also contribute to the pathogenesis of Alzheimer’s disease and may reflect an absence of crystallization inhibitors.”

"Calcium, phosphorus, and fluoride deposits in the pineal gland have been correlated with aging, showing that, as the brain ages, more deposits collect. By old age, the pineal gland contains about the same amount of fluoride as teeth. Pineal fluoride and pineal calcium are correlated."

So, there you go. Meditate on the scientific information behind that, perhaps. No cosmic realignment or chanting required!
