Short Sleep Duration and Sleep Difficulties Among Adults: United States, 2024
Introduction:
This report uses data from the 2024 National Health Interview Survey (NHIS) to describe the prevalence of sleeping less than 7 hours, waking up well rested, having trouble falling asleep, and having trouble staying asleep among U.S. adults by age, sex, and race and Hispanic origin.
Methods:
Point estimates and their corresponding confidence intervals for this analysis were calculated using SAS-callable SUDAAN software to account for the complex sample design of NHIS. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level. Linear and quadratic trends by age group were evaluated using orthogonal polynomials.
Key Findings:
In 2024, 30.5% of adults had less than 7 hours of sleep, 54.8% woke up well-rested, 15.4% had trouble falling asleep, and 18.1% had trouble staying asleep. Asian non-Hispanic adults were most likely to wake up well rested (61.5%) compared with other racial and ethnic groups. The percentage of adults who had trouble falling asleep decreased with increasing age, from 18.3% among adults ages 18-34 to 12.8% among those 65 and older. Women were more likely to have trouble staying asleep (21.4%) compared with men (14.6%).
