Coffee drinkers get more steps but also less sleep, study finds

Coffee is one of the most consumed beverages worldwide, but the pendulum has swung back and forth about its benefits and drawbacks.
New findings from a small study published Thursday in The New England Journal of Medicine, suggest both upsides and downsides: Drinking at least a cup of coffee per day might make you move more but sleep less - and it might put you at higher risk for one type of heart palpitation.
“The big picture finding is that there isn’t just one single health-related consequence of consuming coffee, but that the reality is more complicated than that,” said the study’s lead author, Dr. Gregory Marcus, a cardiologist and professor of medicine at the University of California, San Francisco.
