Understanding the intricate relationship between sleep, circadian rhythms and psychological development is a pressing question within the field of Sleep Psychology. This initiative calls upon researchers to submit manuscripts that contribute to answering the fundamental query, “What is the role of sleep and circadian rhythms in psychological development?” By delving into the intersection of sleep and psychological development, we aim to illuminate this critical connection and its implications for human well-being. Specifically, it is our hope that through addressing this question, we can better design and tailor interventions that aim to enhance psychological well-being across the lifespan.
