What causes blood pressure to rise suddenly after drinking tea?

The reason for the sudden increase in blood pressure after drinking tea may be related to increased sympathetic excitability.

Normal tea has a relatively small effect on blood pressure, but if the patient drinks too much tea or drinks more strong tea, the caffeine component contained in the tea will cause the sympathetic excitability of the human body to increase, so the patient is prone to a sudden increase in blood pressure due to the strong secretion of hormones in the body, which will accelerate the heartbeat and blood circulation. For patients with hypertension and adrenal tumors, the phenomenon may appear more obvious after drinking tea. Therefore, patients in life should pay attention to control drinking drinks containing excitability.
