Sleep is the cheapest performance enhancer in sports. It is also the one most adolescent athletes skip. The data on this is not subtle, and the AAP and American Academy of Sleep Medicine have both been clear for a decade.
The targets, by age. Ages 6-12 need 9-12 hours per night. Ages 13-18 need 8-10 hours. These are not aspirations. They are the AAP’s evidence-based recommendations. A 14-year-old running 6.5 hours of sleep on a school night is not “tough.” They are sleep-deprived, and the performance, mood, and injury cost is real.
Why the 6am practice is a problem. Adolescent circadian rhythms shift later during puberty. The teen brain doesn’t get sleepy until 11pm-midnight, and doesn’t naturally wake until 8-9am. A 6am practice means a 5am wake, which means the kid loses 2-3 hours of biologically necessary sleep on the front end. They cannot just “go to bed earlier.” The biology doesn’t allow it. Programs that schedule daily 6am practices for high schoolers are programs that are accepting reduced performance and increased injury risk in exchange for adult-convenient scheduling.
Sleep deprivation shows up in the body before it shows up in the report card. Studies on adolescent athletes have found that sleeping under 8 hours a night roughly doubles injury risk. Reaction time drops. Cortisol stays elevated. Muscle protein synthesis slows. The kid who slept 6 hours is at higher injury risk for the following week, not just the next day.
Tournament weekends are the worst sleep environment in youth sports. Hotel rooms with paper-thin walls. Late games. Earlier games. Adrenaline. Travel. The standard college athletics protocol for travel sleep includes a sleep mask, white noise, blackout discipline (no phone in bed), and a fixed bedtime regardless of the next day’s start time. Steal that protocol for your travel weekends.
Phones in bedrooms are the problem nobody wants to fix. Blue light suppresses melatonin. Notifications fragment sleep architecture. The Snapchat streak conversation wakes the kid at 11:45pm. The standard recommendation from the AAP is no screens in the bedroom for the hour before sleep, full stop. This is the fight worth having if you have one fight to pick on this topic.
Catch-up sleep on weekends helps a little, not much. Sleeping 11 hours on Saturday after sleeping 6 on weeknights is better than nothing, but it doesn’t fully reverse the cumulative deficit. Aim for consistency. The goal is the same number of hours every night, including weekends, with bedtime within an hour of normal.
The single highest-ROI conversation in your house this year, in terms of athletic performance and injury risk, is the sleep conversation. Not nutrition. Not training. Not gear. Sleep.
