Abstract

• Purpose
  This study was aimed at finding the effects of cycled lighting on body weight, physiological variables and the behavioral state of LBWI (low birth weight infants) in the NICU.
• Method
  The subjects were 20 LBWI at 2 NICUs. They were assigned to an experimental or control group which consisted of 10 subjects in each. Cycled light was applied to the experimental group for 10 days.
• Result
  It was certified that the application of cycled lighting resulted in increased body weight and O₂ saturation, and decreased heart rate of the LBWI. However, there was no effect in decrease of respiration and stabilization of the behavioral state.
• Conclusion
  The application of cycled lighting might be a nursing intervention which would in turn have positive effects on the growth of LBWI.
