Effects on blood pressure of black and green tea

Black tea contains caffeine, so it has an exciting effect on the nervous system and increases its tone. After a cup of this drink, a person's concentration of attention increases, fatigue disappears. Since black tea contains alkaloids, it has a mild arousal effect and increases heart rate. Thanks to the constituents of caffeine: theobromine, xanthine, nofilin, paraxanthine, hypoxanthine, an increase in blood pressure occurs. Black tea has the ability to "hold" pressure for a long time, so it will be useful for people suffering from hypotension, and is contraindicated for hypertensive patients.

Unlike black tea, green tea has a mixed effect on blood pressure. The result depends on the dose of the brewed tea and the mode of its use. Due to its significant caffeine content, green tea increases blood pressure and then lowers it, normalizing the condition. Loosely brewed green tea lowers blood pressure.

When consumed by a healthy person or hypertensive person, caffeine will stimulate the heart and cause vasodilation. As a result, a short-term increase in pressure is possible, due to the effect of caffeine, the headache caused by its increase can disappear. Green tea has a slightly different effect on hypotensive patients. Caffeine normalizes vascular tone, which is often disturbed during hypotension, and increases the frequency of heart contractions. As a result of this effect, a person's blood pressure may rise.
