Why Hydration Affects Your Mood and Focus
Hydration shifts more than thirst. It touches mood swings, attention span, and how quickly the brain locks onto a task. Even mild dehydration around 1–2% body weight loss has been linked in studies from institutions like the University of Connecticut to reduced concentration and slower reaction time. If you work long hours on screens, this shows up earlier than expected - usually as fog, irritability, or sudden mental fatigue.
