Scientists from the University of Bergen and the University of Oslo in Norway found that frequent consumption of energy drinks (about two to three cans per week) was associated with difficulty falling asleep and waking up frequently at night. Research results published British Medical Journal (BMJ) Open.
53,266 Norwegian students (aged 18-23) were included in the study. Subjects provided information about how often they consumed energy drinks. The scientists also collected data on the participants’ sleep patterns, difficulty falling asleep, frequency of waking up during the night, and health status during the day.
The results showed that men who drank two to three energy drinks a week were 35% more likely to go to bed after midnight, 52% more likely to sleep for less than six hours, and 60% more likely to wake up in the middle of the night. more than those who do not drink such drinks or rarely drink them.
It was also found that women who drank energy drinks were 20% more likely to go to bed after 12 a.m., 58% more likely to sleep for less than six hours, and 24% more likely to wake up during the night.
It is noted that the study authors were not trying to prove that tonic drinks cause insomnia or other sleep problems. But many contain too much sugar and caffeine. The stimulating effect of these substances may negatively affect sleep quality.
