Researchers from Walter Reed Army Institute of Research found that service men who drank three or more energy drinks daily were more likely to sleep four or less hours a night on average than those consuming two drinks or fewer.

The study survey included 1,249 male service members randomly chosen from U.S. Army and Marine combat platoons deployed to Afghanistan in 2010. Of those surveyed, 1,000 agreed to have their data used for research and 988 answered the following question: “How many energy drinks do you use per day?” The six response options ranged from zero to five or more drinks per day. The participants were also questioned about:

  • Use of sleep medication
  • Average number of hours of sleep per day
  • Concerns regarding lack of sleep
  • Disruptions to sleep
  • Work impairment associated with sleepiness

Here’s what the researchers found:

  • Study participants who drank three or more energy drinks daily were more likely to report they slept four or less hours per night than participants who drank one to two  or no energy drinks per day.
  • There was no difference in their levels of concern regarding not getting enough sleep.
  • Participants who drank three or more energy drinks daily were more likely than the other groups to report sleep disruption on over half the nights in the past 30 days because of stress related to combat, stress related to personal life, and illness.
  • There were no differences in sleep disruption because of the sleep environment, high operational tempo, nighttime duties, or leisure activities.
  • Participants who drank three or more energy drinks daily were more likely to report  falling asleep while sitting in briefings or while on guard duty, but not while riding in convoys.
  • No differences in energy drink consumption were found regarding having had an accident or making a mistake that affected the mission because of sleepiness.
  • No differences in energy drink consumption were found regarding sleep medication use or receiving prescriptions for sleep medications while deployed.
  • Across sleep disruption and daytime sleepiness outcomes, service members who consumed one to two energy drinks did not differ from those not consuming energy drinks.
