Sleep Quality Factors
- Sleep quality is multifaceted, encompassing timing, intensity, and duration.
- Sufficient sleep duration is crucial, but quality can vary even with enough time.
Defining Good Sleep
- Good sleep quality is defined as spending over 85% of time in bed asleep, with no more than one awakening.
- This awakening should be less than 20 minutes, according to the National Sleep Foundation.
Two-Process Model of Sleep
- Sleep is regulated by two processes: sleep homeostasis (sleep pressure) and the circadian process (wake drive).
- These processes influence sleep architecture, the different stages of sleep throughout the night.
