Most of us spend our days under artificial light, disconnected from the natural rhythms that have governed human biology for millennia. The Sunlight Blueprint reveals how the simple act of aligning with the sun can transform your energy, deepen your sleep, and improve your overall well-being. Drawing on the mainstream scientific consensus, Elena Marsh Whitfield explains the mechanisms behind circadian rhythms, the role of morning light in setting your internal clock, and how afternoon and evening light affects alertness and rest. This book provides clear, practical guidance: when to seek bright light, how to manage screen use without disrupting sleep, and how to adapt for different seasons and lifestyles. You will learn why 150 minutes of outdoor light per week can meaningfully improve mood and sleep quality, and how to create a daily light routine that fits your schedule. No hype, no pseudoscience—just evidence-informed strategies you can use starting today. Part of The Sagewell Wellness Library.
