| Outline of Final Research Achievements |
Previous studies have demonstrated that a light-dark cycle in the Neonatal Intensive Care Unit (NICU) has promoted better sleep development and weight gain in preterm infants than constant light or constant darkness. However, it was unknown whether exposure to light for brief periods at night for medical treatment and nursing care would compromise the benefits brought about by such a light-dark cycle. To establish the facts to this, we developed a special red LED light with a wavelength of > 675 nm which preterm infants cannot perceive. Preterm infants born at < 36 weeks’ gestational age were randomly assigned for periodic exposure to either white LED light or red LED light at night in a light-dark cycle. Activity, nighttime crying and body weight were continuously monitored from enrolment until discharge.
