A new study provides the most direct evidence that there exists a causal link between smoking during pregnancy and Sudden Infant Death Syndrome. Clinicians have long considered prenatal cigarette smoke exposure a major contributing risk factor for SIDS, but researchers had not proved a casual relationship. Other contributing factors include disturbances of breathing and heart rate regulation and impaired arousal responses, thermal stress (primarily overheating from too high temperatures or too much clothing) and sleeping in the prone (belly-down) position.
