Caffeinated teas act as a diuretic, making you expel water through urine. However, they also contain hydrating water. Herbal teas typically have no caffeine. Although the Food and Drug Administration recommends drinking extra water if you consume caffeine during exercise or hot weather, research shows that tea can be just as hydrating as cool boiled water in moderate doses. Tea, coffee, juice, milk and other nonalcoholic beverages count toward your daily water intake.
According to the Center for Science in the Public Interest, caffeine is a stimulant that occurs naturally in tea, but also in coffee, cocoa beans and coffee-flavored ice creams and frozen and regular yogurts.
Caffeine is added to many soft drinks, such as carbonated colas, chewing gum, energy mints and even some over-the-counter pain relievers. Caffeine acts on your central nervous system to make you feel more energetic and wakeful. It can increase your ability to concentrate. Caffeinated drinks can hydrate you just as well as water, as long as you aren't a heavy caffeine user. Moderate caffeine, between 200 and 300mg a day, probably isn't harmful to most healthy adults.
A cup of 8-oz black tea can has 53 mg of caffeine on average, but it may contain between 40 and 120 mg of caffeine depending on the strength of the brew. A 16-oz bottled tea, mixed tea and fruit drinks sold at coffee shops can have between 10 and 100 mg of caffeine. Even decaffeinated tea has some caffeine — between 2 and 10 mg per cup. Comparatively, an 8-oz cup of brewed black coffee has 102 to 200 mg of caffeine, depending on how strong it is, but it has an average caffeine content of 133 mg. The average 12-oz cola has around 54 mg of caffeine.
However, there is another element that may decrease the hydrating benefits. Does tea dehydrate you if you add sugar or cream? Sugar also serves as a diuretic. So, although it will still provide a bit of hydration, tea with sugar is less hydrating than plain tea. On the other hand, the addition of cream may increase hydration. Some studies of athletes’ post-workout recovery strategies have seemed to indicate that milk aids in hydration due to its sodium content.
So far, we’ve mostly taken into account true tea — teas that come from the camellia sinensis plant, all of which contain some caffeine. These include green teas, white teas, black teas, yellow teas, oolongs, etc. However, there is a wide range of herbal blends that are referred to as “teas” but do not come from the same source at all. Aside from a few exceptions, such as maté and guayusa, most herbal teas, or tisanes, do not contain any caffeine. This means that these herbal teas are even more hydrating than caffeinated true teas.
In fact, there are even some herbal teas that provide extra benefits to your entire system. Hibiscus, for example, is a hydrating flower popular in many herbal teas. It is packed with antioxidants and has been known to benefit the kidneys and urinary tract by pulling excess salt from the body. Rose and chamomile are also popular floral tea ingredients that aid in hydration.
All-in-all, tea can dehydrate you. Therefore, we have to drink more water instead of tea. However, with increased water pollution, we should pay more attention to water quality and water treatment. If every household can be equipped with water treatment devices, such as ozone kitchen water purifiers, ozone water sterilizers, ozone water filters, etc, it can greatly improve the quality of our drinking water.
