Sleep age guide · athletes
Sleep age calculator for athletes
Sleep is the most under-leveraged performance enhancer in sport. Even small gaps cost reaction time, recovery, and injury resilience.
The pattern we see in athletes
- Late training, travel, and competition adrenaline push bedtime later than is optimal for the next day's session.
- Time-zone changes during travel disrupt circadian rhythm at the worst possible time — competition.
- Even one night of restricted sleep measurably reduces reaction time and increases injury risk.
Three changes that move the needle.
Strategy 1
Bank sleep before travel
Adding 30–60 min nightly in the week before a time-zone shift reduces jet-lag impact more than any post-arrival fix.
Strategy 2
End hard training 3+ hours before sleep
High-intensity sessions raise core body temperature and cortisol, both of which delay sleep onset. Keep evenings for technique or mobility work.
Strategy 3
Aim for 9 hours during heavy load
During hard training blocks, 9-hour nights are a recovery investment, not luxury. Mah 2011 (Stanford) showed measurable on-court performance gains from extended sleep.
