In addition, there is a certain risk of heart palpitations, as pointed out by the researchers.
For cardiologist and professor of medicine Dr. Gregory Marcus, lead author of the research at the University of California, the problem is not related to the health of those who consume coffee, as the issue may be more complicated than looks.
For the doctor, research on coffee concerns observations and he decided to treat the subject in an analytical way.
Coffee and the influence on health
For research regarding health effects, 100 healthy adults, with an average age of 39 years, living in San Francisco (USA) were recruited. The volunteers were equipped with a kind of tracker, monitoring their steps and the quality of their sleep, their heart rate and monitors that watched their blood glucose levels.
The participants were free to ingest the desired amount of coffee for two days and then they would need to stop drinking coffee for two more days. This experiment was repeated several times over a period of two weeks.
In response, study participants took an average of 1,058 extra steps on coffee drinking days. On these free coffee days, sleep also changed: the participants showed that they slept 36 minutes less. Coffee influenced daily activities and impaired sleep.
In the research, there were also hints that, possibly, coffee affected the heart. According with the doctor. Marcus, the vibration-like heartbeats appeared in the healthy people's experiment.
For the expert, "people with more premature atrial contractions are at greater risk of developing a clinically significant heart rhythm disorder called atrial fibrillation", he reported. Drinking more than one cup a day increased these premature ventricular contractions by 50%.
The warning serves so that people, in general, should not take energy drinks in high doses. This observation is just so that the drink does not manifest anxious symptoms, for example, affecting the heartbeat and influencing possible tremors.
The study highlighted some details that were questionable, but did not point to serious health problems. Coffee is not bad for your health, although it is necessary to control daily doses.
