Have the normal sleep quality indicators been met?

　　To determine whether the indicators of normal sleep quality are met, if there is persistent insufficient or excessive sleep, the sleep quality is considered unmet; if one can quickly enter a deep sleep state, the sleep quality may be considered met. Comprehensive evaluation can be conducted from the following aspects:

　　Persistent insufficient or excessive sleep, less than 6 hours or more than 10 hours; difficulty falling asleep, requiring a long time to fall asleep; frequent awakenings during the night and difficulty returning to sleep, affecting total sleep duration; feeling exhausted, having difficulty concentrating during the day, and even experiencing impacts on work and life are considered as not meeting the criteria for adequate sleep quality.

　　Adults require 7 to 9 hours of sleep daily to meet the recovery needs of the body and brain; quickly entering a deep sleep state and maintaining it for a prolonged period; continuous nighttime sleep with few awakenings, or quickly falling back asleep even after waking up; feeling energetic, being able to concentrate, and not experiencing significant fatigue or drowsiness during the day are considered as meeting the criteria for adequate sleep quality.

　　To ensure sleep quality, it is recommended to establish good sleep hygiene habits, such as maintaining a regular sleep schedule, avoiding caffeine and large meals in the evening, and creating a quiet and comfortable sleep environment.
