06 Nov 2015 --- Energy drinks have grown in popularity for many Americans, but there is growing concern about the health risks of consuming them in large quantities. Because men are the main consumers of energy drinks, a research team lead by Dr. Ronald F. Levant, a professor of psychology at The University of Akron, set out to study a possible link between masculinity, expectations about the benefits of consuming energy drinks, how those expectations affect energy drink use, and the impact on sleep. Their findings were published in the November 2015 issue of Health Psychology.
