the effect of coffee on the heart


This is the main active substance, around which heated debate flares up. The influence of coffee on the heart was studied by the great physiologist I. Pavlov. He showed that this substance stimulates the processes of excitation in the cerebral cortex. A small dose relieves fatigue and drowsiness, increases motor and mental activity. But using a stimulant, which is caffeine in large doses, you run the risk of nerve cells becoming exhausted. Therefore, you need to consider the individual characteristics of the body.

Degree of exposure

Each organism reacts differently to the effects of stimulants. The effect of coffee on the heart is also individual. When dosing, you need to take into account the characteristics of the nervous system. Caffeine significantly enhances cardiac activity. It can cause an increase in blood pressure, which is due to age restrictions. But at a young age, caffeine can hardly affect blood pressure. Elastic blood vessels can withstand such a load.

The mechanism of action of caffeine is as follows. It has a stimulating effect on the nervous system. That is, after a cup of drink, cardiac activity accelerates and blood pressure rises. Caffeine enhances and regulates the processes of excitation in the cerebral cortex. The stimulating effect leads to increased mental and physical performance. This effect lasts several hours, then fatigue appears. In large quantities, it causes death. There is no antidote to it, but for this you need to get about 10 g of caffeine. These are approximately 100 tablets of 0.1 g of caffeine-sodium benzoate.

Coffee and hypertension

Most often, doctors forbid drinking this drink if the patient is diagnosed with hypertension or there are prerequisites for its development.

But modern studies have shown that intravenous administration of caffeine can cause a short-term increase in pressure in people who never drink it. And for those who regularly allow themselves a cup - another, an increase in pressure is practically not observed. Other studies have shown that drinking 5 cups of coffee per day for a long time does not affect the development of hypertension.

Over the next ten years, 700 cases of coronary heart disease were recorded in the sample. At the same time, the risk of the disease in women drinking 6 cups of coffee a day was not higher than their colleagues who refused not only this drink, but also chocolate.

Coffee and arrhythmia

Can I drink coffee with cardiac arrhythmias? This question is also often asked by doctors. In fact, the drink does not affect the appearance and development of arrhythmia.
