Researchers have discovered that newborn children who have mothers who smoke have a lot of probability to show vivid signs of having blood pressure related problems in the early weeks of their life, and it seems that it would likely get worse in the first year.

The study has reported that this early exposure to tobacco may lead to changes in the control mechanisms of the blood pressure of the infant when compared to babies with non - smoking mothers.

Various studies have proved this discovery and the blood pressure of infants with non - smoking mothers had a rise of about 2 per cent when the baby was tilted upright while sleeping after just a week of birth. It was a very important and notable fact that the infants with smoking mothers had almost 10 per cent increase in the blood pressure after the repositioning and another extra 4 per cent increase in just a year.

Abnormal heart rate responses were identified at about three months and when the infant was one year old for tobacco - exposed babies and it was also highly exaggerated.
