Many people wonder whether drinking tea might dry them out rather than hydrate them. This concern is common because some teas especially black and green contain caffeine, a mild diuretic. But when it comes to herbal teas, the story is different.

Short answer: No, herbal tea does not dehydrate you. In fact, most herbal teas help keep you hydrated, support digestion, and provide gentle wellness benefits making them an excellent alternative to water or sugary drinks.

Understanding Dehydration: Why Some Drinks Cause It

Dehydration mainly occurs when your body loses more fluids than it takes in. Caffeinated beverages like coffee and traditional teas (black, oolong, or green) may slightly increase urine output due to caffeine’s mild diuretic effect.

However, modern research (2024 Hydration Study by the European Journal of Nutrition) found that caffeine’s dehydrating effect is minimal unless consumed in very high amounts (over 400 mg per day). For most people, moderate caffeine intake has no significant impact on hydration.

So, caffeine not tea itself is the factor linked to dehydration.
That’s why caffeine-free beverages, such as herbal teas, are ideal for maintaining proper hydration levels.

Does Herbal Tea Dehydrate You? The Science Says No

Herbal teas like chamomile, peppermint, ginger, rooibos, and hibiscus are naturally caffeine-free. These teas are made from herbs, flowers, or roots steeped in water essentially infusions that hydrate your body while delivering plant-based nutrients.

Based on hydration index research conducted by the University of St. Andrews (2024), herbal teas rank similarly to water in their hydrating ability. Many users also report feeling more refreshed when alternating herbal teas with water throughout the day.

In short: Herbal tea not only keeps you hydrated but also offers health-promoting compounds that plain water lacks.
