REZA evidence rating B: Reasonable confidence

Methodology

Systematic review

Population

Observational and experimental studies; athletes

Intervention

Napping (various durations and timing)

Findings

Napping (particularly 20-90 min) improved alertness and aspects of athletic performance in athletes. Short naps (20-30 min) were optimal for acute alertness without grogginess, while longer naps (>90 min) showed risk of sleep inertia.

Outcome measures

Athletic performance measures, alertness, cognitive function

Limitations

Heterogeneity in nap protocols; limited RCTs; varying performance measures; observational data.
