How many nights are needed? The short-term stability of intraindividual variability in sleep parameters derived from accelerometry data in a cohort of normal sleepers

Key Points

• The aim is to determine how many nights of sleep monitoring are necessary to achieve stability in sleep metrics.
• Analyzed accelerometry data on normal sleepers
• Assessed intraindividual variability in sleep parameters
• Examined diagnostic consistency across different monitoring periods
• Longer monitoring periods lead to more stable sleep metrics
• Improved consistency in diagnosing sleep issues
• Recommendations for optimized sleep assessment duration are proposed
