Smoke + hot temperatures = increased SIDS risk

Researchers are a step closer to understanding why cigarette smoke exposure during pregnancy may increase the risk of sudden infant death syndrome (SIDS). SIDS is the unexplained, sudden death of a child younger than one year of age. A new study finds that prenatal cigarette smoke exposure in rats affected breathing responses and immune function of their offspring. Breathing and immune function are further negatively affected by high room temperatures.
