Are You Borrowing Energy from Tomorrow? Why Coffee Alone Won't Hydrate You

A sports journalist warns that many Koreans treat iced Americano (아아) like a daily lifesaver, but caffeine’s strong diuretic effect actually causes more water loss than intake. Drinking coffee instead of water can leave muscles dehydrated and stiff, reducing physical performance—sports medicine says just 2% dehydration can cut ability by nearly 20%. Caffeine only blocks fatigue signals temporarily; it doesn’t create energy, so the perceived boost is an “energy loan” that costs you stronger fatigue later. The advice: drink a glass of water before coffee and at least an equal amount after to replace lost fluids. Coffee is fine in moderation, but water is essential for survival.
