Sleep Smarter

Sleep advice has become crowded with gadgets, supplements, scores, and elaborate routines, making it hard to tell what actually helps. Sleep Smarter cuts through the noise with a practical, evidence-based approach to better rest. Lena U. Voss explains the fundamentals of healthy sleep and shows how to focus on the few habits that matter most: consistent wake times, light exposure, caffeine and alcohol timing, exercise, naps, and a bedroom that supports rest. The book also examines popular sleep products and trends, including trackers, weighted blankets, cooling products, blue-light glasses, melatonin, magnesium, sound machines, sleep apps, mouth tape, and expensive mattresses, separating strong evidence from uncertainty and hype. Readers will learn how to spot exaggerated claims, avoid perfectionism, and build a simple routine they can actually maintain. Reassuring and clear, this guide helps adults make smarter choices, spend less on unnecessary products, and stop turning bedtime into another optimization project.
