Sleep duration refers to the total amount of time spent sleeping during a sleep cycle. It is a critical factor in achieving better sleep quality and overall health. Adequate sleep duration allows the body to undergo essential restorative processes, including muscle repair, memory consolidation, and hormone regulation. Insufficient sleep duration can lead to sleep deprivation, negatively impacting cognitive function, mood, and physical health. Conversely, consistently achieving optimal sleep duration can enhance alertness, improve mood, and support immune function, contributing to a better quality of life.
