Is coffee actually dehydrating?
Coffee is a mild diuretic, but it does not cause dehydration when consumed in moderation. The significant water content in a standard cup of coffee typically offsets the minor fluid loss caused by caffeine. For regular drinkers, tolerance builds quickly, meaning coffee contributes to your daily total water intake rather than reducing it.
- Caffeine increases urine production only slightly.
- Tolerance builds up quickly in daily drinkers.
- Up to 4 cups a day counts towards hydration.
