Tea is loved by many. It has a lot of useful properties, including reducing inflammation, reducing the risk of heart and chronic diseases, and reducing blood sugar levels. However, do not forget that drinking this drink can have negative consequences.

Disruption of biorhythms

Black, white, and green tea contain an average of 14 to 61 mg of caffeine per serving. Although this is less than in a cup of coffee (about 96 mg), this amount is enough to disrupt the so-called “circadian rhythms” – the human biological clock. Drinking too much caffeinated tea in the afternoon or evening can throw off your sleep schedule, which also disrupts your circadian rhythms. As a result, everything can provoke cardiovascular problems, weight gain and weakening of the immune system. Therefore, it is better to drink herbal teas that do not contain caffeine in the afternoon.

So, according to the study, those who drank very hot tea were more likely to develop squamous cell cancer of the esophagus than those who drank warm tea. There are other studies that show that drinks that are too hot cause permanent damage to the esophagus.

Development of anemia

A number of studies by scientists show that the bioactive components of tea – tannins – reduce the assimilation of iron, which can lead to the development of anemia. Thus, according to a study by Pakistani scientists published on the PubMed portal, black and green tea limit the bioavailability of iron to 94%.
