You know the feeling: the 2:30 brain fog, the heavy eyelids, the desperate reach for another coffee. Most of us blame sleep, stress, or willpower. But the real culprit is often simpler: water. Even mild, unnoticed dehydration can significantly impair your concentration, mood, and energy levels. In this practical guide, Owen Radley Marsh draws on the broad consensus of nutrition and physiology research to show you exactly how to harness hydration as your most effective afternoon energy tool. You'll learn how your body's water needs change throughout the day, why the common advice to 'drink eight glasses' misses the mark, and which small rituals—timing your water intake, pairing it with strategic movement, and adjusting for your own environment—can prevent that daily crash before it starts. This isn't about chugging gallons; it's about smart, evidence-informed habits that work with your body's natural rhythms. With clear, actionable steps and no gimmicks, Water and Energy will help you reclaim your afternoons. Part of The Everyday Rituals Library.
