Hydration: the simplest energy booster

Hydration — the simplest energy booster. In the United States, surveys show that many adults begin the day already mildly dehydrated. Even a 1–2% drop in body water can sap concentration, endurance and mood before thirst fully registers. A practical gauge is pale-yellow urine, a low-tech signal that most people can use immediately. The body keeps almost no reserve of this, so daily attention shows up fast. It works along the gut-brain axis, neurotransmitter balance and vascular tone. Do it at the same hour daily so your body starts expecting the cue. For most adults, drink a glass of water first thing in the morning and keep a refillable bottle within reach. Trust the process, then adjust it to how your body responds.
