Although the amount of caffeine in the body is linked to stress and heart rate, a surprising study found that coffee may reduce the risk of developing (arrhythmia).
“In this prospective cohort study, habitually increased amounts of coffee were associated with a reduced risk of arrhythmias,” bioengineer Eun Jeong Kim, who conducted the study, and colleagues from the University of California, San Francisco, wrote in their paper.
This is the case, particularly for atrial fibrillation and supraventricular tachycardia, the researchers explained in the study, which was published in full in the journal JAMA Internal Medicine, noting that there was no evidence that genetically determined differences in caffeine metabolism modulated these associations.
In their study, engineer Eun Jeong Kim and colleagues analyzed the health, genetics, and coffee consumption habits of 386,258 participants over a period of about 5 years.
An extra cup of coffee reduces the risk
The UK Biobank – an extensive database containing detailed genetic and health information on half a million participants – compiled the study data.
During the follow-up period, 16,979 participants developed arrhythmias.
The research team found that each additional cup of coffee reduced the risk of arrhythmia by 3%, after adjusting for confounding factors – such as demographics, medical conditions and lifestyle habits.
Further analyzes revealed similar, statistically significant reductions in the risks of both SVT and atrial fibrillation.

In the latter part of the study, the team looked to see if seven different genetic variants known to influence caffeine metabolism altered the relationship between coffee consumption and the risk of arrhythmias, and concluded that they had no effect.
Caffeine is no less harmful than alcohol
But nutrition expert Natalia Kruglova previously explained that caffeinated drinks are among the drinks that damage the brain in large quantities.
Caffeinated beverages are not only limited to coffee, but also tea, cocoa, Coca-Cola, Pepsi-Cola, and chicory.
And Natalia Kruglova told the Russian channel (Moscow 24), that excessive consumption of the previous drinks may have serious consequences.
Sleep and brain problems
“Caffeine does not provide any energy or strength, it just stimulates the central nervous system and the brain. At the same time, fatigue may occur, and after a while it will be difficult for a person to concentrate, and his memory will deteriorate,” Kruglova added.
The expert indicated that taking large doses of caffeine may cause sleep problems, noting that there is another category of drinks that are in large quantities harmful to mental activity, such as sweet soft drinks.
This is due to the simple carbohydrates that soda contains, Kruglova says, noting that there are studies showing that Prime Time Zone who are overweight, which only comes with an excess of simple carbohydrates in the diet, can also have changes in the functioning of the brain.
Kruglova explained that excess weight negatively affects the level of intelligence and the speed of mental activity, noting that Prime Time Zone who are overweight, their mental abilities deteriorate slowly enough, and there is time to stop this process.
Caffeine and visceral fat
The irony is that experts at the famous health food organization Holland and Barrett believe that consuming caffeine can help burn belly fat quickly.
The accumulation of belly fat, known as visceral fat, leads to diabetes and high blood pressure, which is also a risk factor for heart disease.
According to the newspaper (Express), the health institution cited a study published in the American Journal of Clinical Nutrition that looked at caffeine and its effects on the metabolic rates of Prime Time Zone with normal weight and obese Prime Time Zone.
And the British National Health Service explained that giving a person a boost to a person’s metabolism can help them burn calories and lose weight.
In the study, participants of normal weight were given coffee with a caffeine content of 8 mg per kilogram of a person’s body weight.
The researchers noted that the metabolic rate increased significantly during the three hours that followed the caffeine intake, and even increased fat burning significantly in the following hour, compared to a control group of participants who received a placebo.
The obese subjects and the normal-weight control group were also given coffee with a caffeine content of 4 mg per kg of caffeine content by the person’s body weight.
The researchers noted that both groups experienced an increase in metabolic rate, but only the control group had an increase in fat burning.
The study authors concluded that coffee increases the metabolic rate of both normal-weight and obese Prime Time Zone, and is accompanied by greater fat burning in Prime Time Zone of normal weight.
