Does Red Bush Tea Count as Water Intake?

October 26, 2025 •

According to the Mayo Clinic, a person's total fluid intake, including beverages like tea, contributes to daily hydration. This means that yes, red bush tea counts as water intake and can help you meet your daily fluid requirements.

Quick Summary

Red bush, or rooibos, tea is a caffeine-free herbal beverage that contributes to overall fluid consumption. Because it is made with water and lacks the dehydrating effects of caffeine, it provides net hydration. This makes it a viable and flavorful option for those seeking to diversify their fluid sources beyond plain water. Studies have shown it is no less effective for rehydration than water alone.

Key Points

Yes, it counts: Red bush tea, being primarily water, contributes to your overall daily fluid intake just like any other non-alcoholic beverage.
Caffeine-free advantage: Unlike caffeinated teas, rooibos is naturally caffeine-free, meaning it has no diuretic effect that could potentially counteract its hydrating properties.
Not better than water, but equal: Studies have shown that rooibos tea is no more or less effective for short-term rehydration than plain water.
Rich in antioxidants: In addition to hydration, red bush tea provides a healthy dose of antioxidants, which can offer various other health benefits, such as heart health support.
Great alternative for flavor: For those who find plain water boring, rooibos tea offers a flavorful, caffeine-free alternative to encourage consistent fluid consumption.

Understanding Hydration and Fluid Intake

For many years, a persistent myth suggested that any drink containing caffeine, like tea and coffee, was inherently dehydrating. The logic was that caffeine is a diuretic, which causes the body to excrete more fluid through urination. While it is true that caffeine has a mild diuretic effect, modern research has largely debunked the notion that it negates the hydrating benefits of the water used to make the beverage. In fact, most people take in more water from their daily tea or coffee than they lose due to the mild diuretic effect. The key takeaway is that fluids are fluids, regardless of whether they contain caffeine, and all contribute to your total daily intake.

Why Red Bush Tea is a Great Hydrating Choice

Red bush tea, also known as rooibos, is a unique herbal infusion that offers several benefits for hydration. Unlike traditional green or black teas, rooibos is naturally caffeine-free. This is a significant advantage, especially for individuals sensitive to caffeine, as it removes any potential for even a mild diuretic effect. The natural, earthy flavor of rooibos can also make it a more appealing option for those who find plain water unexciting, encouraging greater fluid consumption throughout the day. Furthermore, a study involving collegiate wrestlers found that rooibos tea was no more or less effective for rehydration than plain water over a one-hour period.

Beyond Hydration: Additional Benefits of Rooibos

While its hydration properties are clear, rooibos tea offers a host of other health benefits that make it an excellent addition to your diet. These perks include:

Rich in Antioxidants: The tea contains unique polyphenols with strong antioxidant properties, including aspalathin and nothofagin. Antioxidants help protect the body from cellular damage caused by free radicals.
Heart Health: Studies suggest that rooibos may improve heart health by positively influencing cholesterol levels and potentially lowering blood pressure.
Low in Tannins: Compared to true teas, rooibos has very low levels of tannins. This means it doesn't interfere with iron absorption, a crucial mineral for many individuals.
Stress Reduction: The absence of caffeine and the tea's gentle, soothing nature can promote relaxation and help reduce stress.
Digestive Health: It can act as a digestive tonic, helping to soothe and support a happy digestive system.
