Sleep after 40 can feel frustratingly different: you may fall asleep, then wake at 2 or 3 a.m., wake too early, or spend enough time in bed without feeling restored. The Sleep Reset After 40 offers a practical, 30-day system designed for adults who want a natural, structured way to improve sleep quality and rebuild better habits. Rather than a scattered list of tips, this book helps readers understand why sleep changes with age, identify their personal sleep type, and track the habits that may be disrupting rest. Step by step, it guides readers through resetting the body clock, creating a sleep-friendly bedroom, managing caffeine, alcohol, food, and exercise, and calming the racing brain at night. It also provides clear strategies for nighttime awakenings, including a 3 A.M. rescue protocol, plus special guidance for stress, anxiety, perimenopause, menopause, and when medical attention may be needed. By the end, readers will have a personalized sleep blueprint, a sustainable evening routine, and a long-term plan for waking up more energized and reclaiming their nights.
