New research explains link between smoking and SIDS
Date:1/29/2008

l event in the adaptation of life outside the wombis impaired due to nicotine exposure.

At birth, the nervous control of the adrenal gland is not active and so a baby relies on these direct oxygen sensing mechanisms to release catecholamines, says Colin Nurse, academic advisor on the study and a professor in the department of Biology. But nicotine causes premature loss of these mechanisms, which would normally occur later in development after nervous control is established. Thus, the infant becomes much more vulnerable to SIDS.
