The relationship between sleep/awake rhythm development and caregiving activities

Ensuring proper central nerve system (CNS) development is the core issue in premature infant care. Because an infant's sleep pattern (or sleep state) manifests his or her CNS integration, recognizing infant sleep patterns is essential for caregivers involved with developmental care. This article aims to explore the development of biological rhythms and infant sleep/awake states, factors influencing sleep states, and the effectiveness of various interventions to promote infant sleep. Five major factors that influence infant sleep states include noise, light, environmental temperature, physical contact with caregivers, and body position. Accordingly, we propose interventions to improve infant sleep quality to facilitate the growth of premature infants.
