Does Coffee Dehydrate You? Myth vs Reality Explained
“Coffee dehydrates your body.”
You’ve probably heard this many times.
But is it actually true—or just a myth?
Let’s uncover the reality.
The Origin of the Dehydration Myth
Coffee contains caffeine, which is a mild diuretic.
This means it can increase urine production slightly.
Because of this, many people assumed coffee causes dehydration.
So, Does Coffee Really Dehydrate You?
Short answer: No, not in normal amounts.
Research shows that moderate coffee consumption does not lead to dehydration.
Your body adapts to caffeine, reducing its diuretic effect over time.
