Premature infants requiring intensive care or surgery after birth are reportedly less sensitive to temperature change later on in life.
According to a study published in Pain, premature delivery results in life-long impairment of the child's sensory perception.
Compared to full-term children, premature babies experience similar pain; there are, however, minor differences in the way these two groups cope with pain.
A University College London study showed that premature children particularly those undergoing early surgical operations are less sensitive to temperature and pain in locations close to their surgical scars.
Temperature and pain perception are transmitted by the same nerve fibers. Any damage to these fibers can affect the child's perception of pain and temperature.
Scientists believe the severity of injury and trauma in early life influences the degree of sensory damage.
Previous studies had reported that premature babies are more prone to developing disability and various illnesses when they grow up.
