The U.S. military has warned military personnel that consuming too many energy drinks can do "some serious harm to your bodies." The pentagon's official science blog detailed health risks of energy drinks while citing a report that revealed that soldiers in the field who consumed multiple energy drinks each day were actually more likely to fall asleep on duty.
The study was conducted by the Walter Reed Army Institute of Research and it examined data from 1,000 Army soldiers and Marines in Afghanistan in 2010 who had consented to having their information used for research purposes. The data collected by Joint Mental Health Advisory Team 7 (J-MHAT 7) to Operation Enduring Freedom in Afghanistan was the first to include questions about the consumption of energy drinks, the researchers reported on the CDC's website.
The study revealed that almost half of deployed members of the military drank at least one energy drink each day. Nearly 14 percent of the deployed personnel reported that they drank three or more energy drinks a day. The report claimed that the energy drinks can have negative side effects. At three or more energy drinks each day, the military personnel were more likely to report that they experienced sleep disruption related to stress and illness. They were also more likely to fall asleep on guard duty or at briefings.
