English breakfast tea contains caffeine, a diuretic compound that can cause dehydration
English breakfast tea, like many other teas, contains caffeine. Caffeine is a diuretic compound, which means it can cause you to urinate more frequently. This increase in urination can lead to dehydration if fluid intake is not maintained. However, the amount of caffeine in tea is typically very low compared to other caffeinated beverages. The average cup of tea contains around 30–75 mg of caffeine, while a cup of coffee usually contains 100 mg or more.
While caffeine can have diuretic effects, the impact of tea on hydration is influenced by various factors, including the amount consumed and individual tolerance to caffeine. Research suggests that drinking moderate amounts of caffeinated tea can be as hydrating as water. In one study, participants who consumed 800 ml of coffee or water over three days showed no difference in markers of hydration. Similarly, another study found no significant difference in hydration between participants who drank black tea or water.
To experience a noticeable diuretic effect from caffeine, one would typically need to consume more than 500 mg or the equivalent of 6–13 cups of tea. Therefore, drinking a few cups of English breakfast tea daily is unlikely to cause dehydration for most people. However, it's important to note that caffeine sensitivity varies among individuals, and some people may find that even small amounts of caffeine increase their urination.
In summary, English breakfast tea does contain caffeine, a diuretic compound. However, the caffeine content is relatively low, and moderate consumption is unlikely to lead to dehydration. Maintaining adequate fluid intake and being mindful of individual caffeine sensitivity are essential factors in maintaining proper hydration when consuming caffeinated beverages like English breakfast tea.

However, the caffeine content in English breakfast tea is very low, so a few cups a day may not dehydrate you

Research has shown that it would take approximately 6 to 13 cups of tea to have a noticeable diuretic effect, which is significantly more than the typical consumption amount. In fact, studies have found that black tea is not significantly different from water in terms of hydration maintenance, and tea can be an interesting alternative to plain water to meet daily fluid requirements.
While English breakfast tea can contribute to hydration, it's important to note that it should not be the only source of fluids. Drinking water is still essential to ensure proper hydration, as the body needs water to function optimally. Additionally, herbal teas, which are generally caffeine-free, can be a good option to include in your fluid intake throughout the day.
