Put It In Context
The Pittsburgh Sleep Quality Index (PSQI) is used in clinical research worldwide to assess sleep quality over the past month. Studies show that roughly 35% of adults globally report poor sleep quality (score below 12). Sleep quality — distinct from duration — determines how much time you spend in deep slow-wave sleep and REM. Even 8 hours of fragmented sleep can leave you more fatigued than 6 hours of consolidated, high-quality sleep.
