Does drinking coffee really make one's heart palpitations? The truth turned out to be like this

The Two-stage Physiological Response Theory of Overdrinking Coffee

Some people will experience fever, sweating, and sluggish response after drinking 7 or 8 cups of coffee in a row. Some scholars call it the physiological reaction of the first stage of overdrinking coffee. If you continue to drink it, There will be heart palpitations, which is called the second phase of the physiological response to overdrinking coffee. The reason for these abnormal physiological reactions is generally believed to be caused by the caffeine in coffee.

The effect of caffeine is inversely proportional to the gene expression in the human body

Caffeine is a xanthine alkaloid compound and a stimulant that promotes central nervous system strengthening. It is found in coffee, tea and energy drinks. It has the effect of temporarily boosting the spirit and driving away drowsiness. Caffeine is also the most commonly used psychotropic drug in the world. In North America, 90% of adults consume caffeine every day.

However, caffeine-containing beverages have different reactions to the human body. Some people are very sensitive to coffee and can have a strong reaction after drinking a few cups, but some people still have no feeling after drinking several cups. A team in the United Kingdom did a study on coffee drinkers and found that there is a gene called PDSS2 in the human body. The higher the level of protein expressed by this gene, the more inhibited the expression of genes related to the caffeine metabolism pathway. , There is a reverse correlation between the two.

Is there any relationship between caffeine and heart palpitations?

As mentioned earlier, palpitations and arrhythmia are closely related. Therefore, there are also a lot of scholars studying the relationship between caffeine and heart palpitations.

For example, a research team in the United States found 50 patients with arrhythmia and divided them into two groups. One group drank decaffeinated coffee, and the other group drank coffee with 200mg caffeine. After monitoring for 3 hours, they did not find these two groups of diseases. There is any difference in the indicators of palpitations.

In another study published in the American Journal of Medicine, 22 patients with ventricular frequency or ventricular fibrillation were found, and their ECG was monitored 1 hour before and after they drank 275mg of caffeine coffee. The result was no Caffeine can induce or aggravate arrhythmia.

From the perspective of Western medicine, it is believed that drinking coffee is not directly related to heart palpitations. If abnormal heartbeat occurs, it should be caused by physiological changes, such as early atrial contraction, early ventricular contraction, or rapid heartbeat. The blame is on the coffee.

From the perspective of traditional Chinese medicine, in addition to refreshing and refreshing, coffee also has the effects of helping kidney yang and diuresis, which can increase urine output and improve abdominal distension and edema. Therefore, Chinese medicine uses coffee to treat damp-heat dysentery or prostate hyperplasia. For the symptoms of damp-heat problems, Chinese medicine also recommends eating broad beans with coffee to prevent stroke and Parkinson's disease.

The problematic ingredient in coffee is tannic acid, not caffeine

If you really insist on picking the ingredients in the coffee, it should be tannic acid (commonly known as tannin), which contains 8%-9% in green coffee beans, and 4%~5% in raw beans after roasting. This kind of polyphenols will indeed make the absorption of protein by human cells worse and cause protein to coagulate. It binds with gastric acid and precipitates in the stomach. It will hinder the absorption of iron, easily damage the gastric mucosa, and also cause intestinal peristalsis. It slows down and slows down the digestive function, but this has nothing to do with the symptoms of heart palpitations, and as long as you don’t drink too much coffee, the effect of tannin on the human body is actually limited.

However, you must pay attention to the quality of coffee, and avoid unroasted or burnt coffee beans.

However, you must pay attention to the quality when drinking coffee. If the coffee beans are picked when they are not yet ripe, or the coffee beans are not roasted during roasting, or the coffee beans are over-roasted and coked, and improper preservation is also caused. The deterioration of coffee beans or coffee powder produces alkaloids harmful to the human body, which may still cause palpitations and burden the heart.
