Pre-workout supplements linked to poor sleep in teenagers and young adults

Topic: Health

A new study found that people who use popular pre-workout dietary supplements are more likely to have very short sleep durations. This can be harmful for their physical and mental development.

Researchers from the University of Toronto studied over 16-30 year olds who used pre-workout supplements like Bang!, Jack3D, or C4. They found that those who used these supplements were more than twice as likely to sleep less than five hours a night compared to those who didn't use them. This is concerning because most teenagers and young adults need around 8-10 hours of sleep each night for healthy development.

The study's lead author, Kyle T. Ganson, explained that these supplements often contain high levels of caffeine and stimulant-like ingredients. These can make it harder to fall asleep or stay asleep. The researchers are worried about the potential risks to young people who use these supplements.

The team is calling for health professionals, such as pediatricians and social workers, to talk to young people about their use of pre-workout supplements. They also recommend practical steps like avoiding these supplements 12-14 hours before bedtime.

Why It Matters

This study matters because many Indian students are influenced by Western fitness trends and may be using these supplements without knowing the potential risks to their health. It's essential for them to understand how these products can affect their sleep and overall well-being.
