Healthy Sleep: Subjective vs. Objective Measures
The paper reviews the approaches to measure healthy sleep. Subjective and objective (e.g. polysomnography, actigraphy) approaches to assess sleep quality and duration are considered. The novel recommendations by the National Sleep Foundation on sleep duration/time and sleep quality in different age groups are presented. Subjective and objective assessments, their discrepancies and the underlying causes are discussed. The review also considers the opportunities of the integral sleep assessment in personalized medicine.
