Blood of SIDS infants contains high levels of serotonin

Blood samples from infants who died of Sudden Infant Death Syndrome (SIDS) had high levels of serotonin, a chemical that carries signals along and between nerves, according to a study funded in part by the National Institutes of Health. The finding raises the possibility that a test could be developed to distinguish SIDS cases from other causes of sleep-related, unexpected infant death.

The study, led by Robin L. Haynes, Ph.D., of Boston Children's Hospital and Harvard Medical School, appears in the Proceedings of the National Academy of Sciences.

SIDS is the sudden death of an infant under one year of age that remains unexplained after a complete autopsy and death scene investigation. In the current study, researchers reported that 31 percent of SIDS (19 of 61) had elevated blood levels of serotonin. In previous studies, the researchers reported multiple serotonin-related brain abnormalities in SIDS cases, including a decrease in serotonin in regions involved in breathing, heart rate patterns, blood pressure, temperature regulation, and arousal during sleep.

Taken together, the researchers wrote, the findings suggest that an abnormality in serotonin metabolism could indicate an underlying vulnerability that increases SIDS risk and that testing for serotonin could distinguish certain SIDS cases from other . However, they caution that more research is needed.

NICHD's Safe to Sleep campaign provides information on ways to reduce the risk of SIDS and other sleep-related causes of infant .

SIDS is diminished when good ventilation and oscillating fans are present.
repeating a false claim is religion, not science

if you can't produce a peer reviewed journal study and validation, then you're making pseudoscience sh*t up

however, due to your exposure and frequent public information published in your own name with links you've provided, you can be sued for malpractice and fraud when and if someone attempts to use your techniques and causes a baby to die from exposure and or hypothermia

More boy babies die from circumcision than from SIDS in the U.S.. Why is the media afraid to make a big deal out of circumcision the way they do SIDS? Is it censorship?

Oh, and in case you don't know, far less boys are at subjected to circumcision than to the risk of SIDS, yet it still kills more, and has for years (it used to be much worse).

Coleman-Phox K, Odouli R, and Li D. Use of a fan during sleep and the risk of sudden infant death syndrome
except that there is absolutely no mention of pheromones in that study at all, and there is this to consider
Although the exact underlying mechanism of the observed association is not yet known, this finding is consistent with the hypothesis that reducing rebreathing may reduce the risk of SIDS. It has been reported that increasing the air turbulence with a fan could prevent the accumulation of carbon dioxide in a mechanical model of infant rebreathing.10
not only that but this is a singlular study, and you should also read
The limitations of this study
because there is plenty of reason to follow up with more studies to either validate or invalidate the findings, according to the scientific principle, which you've never once showed aptitude in
