The Claim
Adolescents aged 10–16 who regularly consume caffeine (at least two servings daily for three or more years) have habitual bedtimes that are approximately 57 minutes later and total time in bed that is approximately 53 minutes shorter than those who do not consume caffeine.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Teenagers aged 10 to 16 who drink at least two caffeinated beverages daily for three or more years go to bed about 57 minutes later and spend 53 minutes less time in bed than teens who do not consume caffeine regularly.
See the scientific wording
Adolescents aged 10–16 who regularly consume caffeine (at least two servings daily for three or more years) exhibit later habitual bedtimes (by approximately 57 minutes) and shorter total time in bed (by approximately 53 minutes) compared to non-consumers, suggesting a consistent association between caffeine intake and delayed sleep timing in this population.
Caffeine blocks a chemical in the brain that tells the body it's time to sleep, which keeps the brain active longer and delays when a person falls asleep. This also reduces the depth of sleep, so the person spends less time in bed overall.
What the research says
1 studyStudy: Caffeine Consuming Children and Adolescents Show Altered Sleep Behavior and Deep Sleep
Teens who drink caffeine like soda or energy drinks tend to go to bed later and sleep less than teens who don’t, and this study found exactly that — caffeine drinkers stayed up nearly an hour later and got less sleep overall.
