Coffee can have a certain effect on blood pressure and may lead to an abnormal increase in blood pressure. Therefore, espresso is not recommended for people with high blood pressure, patients with cardiovascular and cerebrovascular diseases, women during pregnancy, and people who are highly sensitive to caffeine.
Coffee contains caffeine, which can stimulate sympathetic nerve excitation, which in turn causes a series of cardiovascular system changes, including increased heart rate, vasoconstriction, increased blood pressure.
However, such changes manifest differently in different individuals, and may not be obvious in long-term coffee drinkers. For caffeine sensitivity and other conditions, it may be obvious, and even panic attacks may occur.
If you experience any of the above symptoms, it is recommended that you stop drinking coffee. If necessary, consult a doctor.
