Why does coffee make me sleepy instead of active?
Actually, yes. Can drinking coffee dehydrate you?
Yes, caffeine is a natural diuretic, which means that it can increase urine production and potentially lead to dehydration if not balanced with adequate water intake. However, the amount of drinking coffee necessary to cause dehydration varies and can depend on factors such as individual coffee tolerance, hydration status prior to drinking coffee, and surrounding environmental factors.
