PERSPECTIVE: The Long-Term Effects of Light Exposure on Establishment of Newborn Circadian Rhythm

J Clin Sleep Med. 2018 Oct 15;14(10):1829-1830. doi: 10.5664/jcsm.7426.

Abstract

Development of newborns continues postnatally. Evidence has accumulated on the early life programming effects of light exposure on the maturing visual axis and the developing circadian rhythm. Consideration of the effects of light at night and insufficient light during the day should occur when giving anticipatory guidance in the care of newborn infants. Long-term health consequences of light imprinting may occur with inappropriate light-dark environments during the newborn period.

Keywords: circadian rhythm; light exposure; newborn.
