Neonates were given phototherapy, calculated in hours, interrupted only for feeding, cleaning and blood sampling (time taken for these activities were reduced from the calculated duration of phototherapy). Daily weight was recorded and temperature monitoring was done every 6th hourly. Hypothermia was defined if the temperature recordings fell below 36 degree Celsius [12]. Hydration status was assessed based on physical examination and weight monitoring. Dehydration status was defined if there was documented weight loss greater than 5% in a day [13]. Any side effects including skin darkening, rashes, and diarrhea were noted. Tanning of skin under phototherapy was considered as evidence of skin darkening
