In addition, it is worth noting that patients with hypertension should avoid drinking caffeinated drinks when their work pressure is high. Because caffeine in coffee may lead to high blood pressure, if coupled with emotional tension, it will have a dangerous multiplier effect.
Disadvantaged people:
Suffering from hypertension, coronary heart disease, arteriosclerosis and other diseases-drinking coffee for a long time or in large quantities can cause cardiovascular diseases.
