A large-scale Norwegian study has found that young people who drink energy drinks experience poorer sleep quality. The more frequently they drink these beverages, the less sleep they get at night. Even occasional consumption can impact sleep.
The study included 53,000 university students aged 18 to 35. The participants reported their energy drink consumption in categories: once a week, 2-3 times a week, 4-6 times a week, 1-3 times a month (occasionally), and never.
The research revealed a clear dose-response relationship between drinking energy drinks and reduced sleep time and efficiency. Insomnia was more common among those who drank energy drinks daily, who slept about half an hour less than those who drank them occasionally or not at all. The more energy drinks consumed, the higher the risk of poor sleep. Compared to those who drank them occasionally or not at all, daily energy drink consumers had double the risk (men) or an 87% higher risk (women) of getting less than six hours of sleep per night.
