University of Thessaly study links energy drinks to adolescent sleep debt

A study conducted by the University of Thessaly and published in the journal Nutrients examines the relationship between energy drink consumption, sleep debt, cognitive function, physical activity, and adolescent obesity.

Dr. Georgios K. Sakkas, a professor at the University of Thessaly, suggests that energy drink use in teenagers may serve as an indicator of insufficient sleep rather than just a simple intake of caffeine or sugar. The research highlights a potential vicious cycle: inadequate sleep leads to fatigue, which prompts the use of stimulants to maintain focus or energy for studies and sports. This increased caffeine intake can further disrupt sleep quality.

This cycle may lead to decreased physical activity and poorer dietary choices, which can indirectly contribute to an increased risk of weight gain and obesity. The study emphasizes that sleep is critical during adolescence for memory, learning, mood regulation, and physical development.
