- Soldiers serving in recent war zones across the globe have grown particularly keen on energy drinks.
- US Military soldiers in the field were more likely to fall asleep on duty if they consumed multiple energy drinks a day.
The US military has warned its troops over the dangers of over consumption of energy drinks. It added that energy drinks could do "some serious harm to your body."
A post on the pentagon's official science blog this week details the health risks involved, citing a report that found soldiers in the field were more likely to fall asleep on duty if they consumed multiple beverages a day.
‘Beverages marketed as energy drinks have become a popular form of caffeine consumption targeted at young males, with some brands containing the caffeine equivalent of 1–3 cups of coffee or cans of soda.’
Energy drinks contain caffeine, herbal substances, amino acids, sugars and intend to boost physical energy or mental alertness.
The study by the Walter Reed Army Institute of Research, titled "Energy drink consumption and its association with sleep problems among US service members on a combat deployment," looked at data from over 1,000 soldiers and Marines conducting operations in Afghanistan in 2010.
The research found that nearly 45 percent of deployed military personnel consumed at least one energy drink daily, while nearly 14 percent reported drinking three or more per day.
Service members who drank three or more energy drinks per day were more likely to report ≤4 hours of sleep on average per night (38.2%) than service members who drank one to two (18.4%) or zero (23.9%) energy drinks per day.
"These products generally are unregulated and can have negative side effects," the report said. "Those who drank three or more drinks a day also were more likely to report sleep disruption related to stress and illness and were more likely to fall asleep during briefings or on guard duty."
The military has long had an interest in keeping troops on the battlefield awake, and from Instant coffee to caffeine-infused chewing gum in military rations, access to stimulants has been a feature of being deployed overseas.
One of the more commonly seen brands, Rip It, is actively involved in supporting military groups like the USO and highlights its military connection in its online marketing.
On the company's website it says their drink "has been tested on the battlefield and is a favorite of our troops."
Dr. Patricia Deuster, professor and director of the Consortium for Health and Military Performance at the Uniformed Services University of the Health Sciences, told the Defense Department's science blog that "doctors don't know what the effects of (energy drink) ingredients are in larger doses."
