When was sids first discovered

SIDS is part of a larger category of unexpected as opposed to unexplained infant deaths called SUDI sudden unexpected death in infancy. Babies who die suddenly but whose causes of death are later explained infection, brain abnormality, cardiac dysfunction, etc.

SIDS is a mysterious syndrome, since by its very definition the cause cannot be determined. But certain risk factors do exist. Some babies are more at risk than others.

For example, SIDS is more likely to affect a baby who is between 1 and 4 months old, it is more common in boys than girls, and most deaths occur during the fall, winter and early spring months. While the cause of SIDS is unknown, many clinicians and researchers believe that SIDS is associated with problems in the ability of the baby to arouse from sleep, to detect low levels of oxygen, or a buildup of carbon dioxide in the blood.

When babies sleep face down, they may re-breathe exhaled carbon dioxide. Normally, rising carbon dioxide levels activate nerve cells in the brainstem, which stimulate the brain's respiratory and arousal centers.
