French researchers have found premature babies born to mothers who smoked heavily during their pregnancy are more likely to have disruptive sleep cycles.
Pre-term babies born to mothers who smoked more than ten cigarettes a day slept an average of two hours less a night than those born to non-smokers --and-- their sleep was more fragmented. These abnormal sleep patterns can ultimately cause developmental problems ... as well as cardiovascular and respiratory issues that can be life threatening in later years.
