Children exposed to nicotine in the womb find it harder to fall asleep than those born to mums who didn’t smoke in pregnancy, a study of 800 American children has found.
Almost half the children in the study had some exposure to nicotine in the womb while 434 had not. They were divided into age groups of 1 month to 4 years, 5 to 8 years and 9 to 12 years. Sleep problems were found to be more common in the group exposed to nicotine in all of the age groups.
As well as problems dropping off, the babies of smoking mums-to-be also had restless sleep, unable to remain asleep for long, reports NDTV.
This is another in a series of studies that have found smoking in pregnancy is linked to a variety of health problems for children in later life.
