Sleep quality refers to how well a person sleeps and the overall satisfaction with their sleep patterns. Research in this area focuses on understanding the factors that contribute to good or poor sleep quality, such as sleep duration, sleep disturbances, sleep environment, and individual differences in sleep patterns. Studies in this field also examine the impact of sleep quality on physical and mental health outcomes, including cognitive function, mood, and overall well-being. Researchers often use subjective self-report measures and objective measures like actigraphy or polysomnography to assess sleep quality. The goal of this research is to identify effective interventions and strategies to improve sleep quality and promote better overall health and quality of life.
