Tea is a healthy drink that has been shown to have a number of beneficial health effects. The beneficial health effects of tea are thought to stem from the presence of antioxidants in the tea. However, tea clearly has benefits that may not be explained by the presence of antioxidants. In particular, tea is a calming drink, and those who are under stress may derive significant benefits from consumption of tea. For example, in one study researchers administered tea to a group of healthy individuals over a period of 6 weeks. During this time the tea was able to significantly reduce blood pressure and heart rate elevations caused by the setting of specific behavioural tasks. In addition, perceived stress levels also declined and relaxation levels increased, and this was accompanied by significant reductions in blood cortisol levels, suggesting that the tea had provided a significant anti-stress effect. Tea can therefore provide consumers with a relaxing and calming effect due to its ability to reduce stress levels.
