Researchers from the University of Toronto have examined sleep habits among young people aged 16 to 30. The analysis is based on data from the Canadian Study of Adolescent Behaviors.
The results, published in Sleep Epidemiology, show a clear difference between young people who use pre-workout supplements and those who do not.
Individuals who had used the products within the past year were more than twice as likely to sleep only five hours or less per night.
Sleep plays an important role in concentration, learning, and physical development during youth, which is why the findings are attracting attention among the researchers behind the study.

What do the products contain?
Pre-workout supplements are marketed as products that can provide extra energy before exercise. They are especially popular among young people who train in fitness centers.
According to the researchers, many of the products contain large amounts of caffeine. One serving can contain between 90 and more than 350 milligrams of caffeine.
For comparison, a can of cola contains about 35 milligrams of caffeine, while a cup of coffee typically contains around 100 milligrams, according to the University of Toronto.
