Scientists have announced that black and green tea cause a sudden rise in blood pressure, but after minutes it returns to its normal level.
The Daily Express indicates that this study was devoted to determining the effect of black and green tea on blood pressure.
The researchers point out, “They believed, from their study of the properties of black and green tea, that after drinking tea, the level of high blood pressure would decrease. However, the results were unexpected, as it became clear that the two types of tea cause a sudden rise in the level of arterial blood pressure.”
The experiment involved healthy and sick volunteers, divided into two groups by the researchers, who had to drink five cups of black and green tea over the course of a week.
The results showed that both black and green tea cause high blood pressure, but it returns to normal quickly.
According to the researchers, the tea drink 30 minutes after drinking it caused a sudden rise in the level of arterial blood pressure, but within an hour it returned to its normal level.
And the researchers add, despite these surprising results, the benefits of tea drink remain more than harmful
