Approximately what percentage of US adults have insufficient sleep?

The correct answer, which indicates that approximately 33% of US adults have insufficient sleep, is supported by various studies and data collected by health organizations over the years. Insufficient sleep is generally defined as getting less than the recommended 7 hours of sleep per night for adults.

Research suggests that a significant segment of the adult population struggles to achieve adequate sleep, contributing to various health issues including obesity, cardiovascular diseases, and impaired cognitive function. The figure of 33% reflects real-world findings that highlight how lifestyle, work commitments, stress, and other factors can lead to sleep deprivation in a large portion of the population. This statistic emphasizes the importance of sleep hygiene and the need for interventions to improve sleep quality among adults, which is crucial for overall health and well-being.
