Findings from a new study were published on Thursday in The New England Journal of Medicine and suggest the advantages and disadvantages of drinking coffee. Drinking at least one cup of coffee a day, for example, can make you move more, but as a result, you'll sleep less, in addition to increasing your risks of a type of heart palpitations.
The author of this new study, Dr. Gregory Marcus, a cardiologist and professor of medicine at the University of California, San Francisco, said the following: “the overall conclusion is that there is not only a single health consequence of coffee consumption, but that the reality is more complicated than that it".
“The vast majority of research on the subject has been observational, which means we just look and see what happens to things. people who drink and don't drink coffee, which is profoundly limited by the possibility that there may be some other characteristic," he said. Marcus. "The only way to mitigate these potential effects was to conduct a randomized interventional trial."
How did they do this study?
In order to have a better idea of the immediate effects of coffee on the health of the human body, the authors of the study recruited 100 healthy adult subjects, mean age 39, from the San Francisco area.
They fitted all participants with Fitbits to track their steps and sleep, with continuous blood glucose monitors and EKG machines, which track your rhythms cardiac. Each participant was randomly assigned to drink as much coffee as desired for two days and to then go without drinking for two days, thus repeating this cycle for a period of two weeks.
The study authors found that on days when participants consumed coffee, they took an average of 1,058 more steps than on non-caffeine days. However, on those days, the participants' sleep was impaired, as they slept 36 minutes less. The more coffee they drank, the more physical activity they did and the less sleep they had to sleep.
In that study, they noticed that coffee also seemed to affect the heart. However, the researchers found no evidence of a significant relationship between coffee consumption and heart palpitations, which are "Very common early heartbeats that we all experience arising from the upper chambers of the heart," said researcher Marcus. He added: "People with more premature atrial contractions are at greater risk of developing a clinically significant heart rhythm disorder called atrial fibrillation."
