Most experts consider three to four glasses of this drink, or 710-950 ml per day, to be a safe dose of tea.
At the same time, the body’s sensitivity to tea is influenced by individual characteristics. People may also be sensitive to less tea. Side effects that occur after tea are associated with the action of its components, such as caffeine and tannins: in some cases, the body is particularly susceptible to them.
One of the harmful properties of tea is the suppression of iron absorption processes – this effect is created by the tannin compounds.
Tannins in tea reduce the absorption of iron by binding to it and removing it from the body. If a person has low iron levels, tea should be taken with caution.
Also, remember that tea contains caffeine. Consuming large amounts of caffeine results in a person’s sympathetic nervous system being stimulated. As a result, a person begins to experience constant tension, cannot relax, faces insomnia, anxiety and irritability. In addition, caffeine is a known headache provocateur.
But for those who do not experience discomfort after tea, experts recommend drinking it in moderation.
