Current headline statistics
30.5%
Adults whose usual sleep duration in a 24-hour period averaged fewer than 7 hours.
This is self-reported, not measured sleep. Duration alone doesn't tell you about sleep quality.
15.4%
Adults reporting trouble falling asleep most days or every day in the past 30 days.
Self-reported. This is not the same as a clinical diagnosis of insomnia.
18.1%
Adults reporting trouble staying asleep most days or every day in the past 30 days.
Self-reported. Trouble staying asleep can have many causes.
54.8%
Adults reporting they usually woke up feeling well-rested.
Feeling rested doesn't always match what a sleep study would measure.
12.9%
Adults reporting use of any medication or supplement to help fall or stay asleep most days or every day.
Includes prescription and over-the-counter products. Using one doesn't mean it works.
35.2%
Adults reporting short sleep duration (fewer than 7 hours).
State estimates come from a different survey than the 2024 national figures, so they can't be compared directly.
Women reported more trouble falling and staying asleep than men. Adults ages 50 to 64 reported especially high rates of trouble staying asleep. Black adults reported higher rates of short sleep than several other groups in the 2024 survey. These are population patterns shaped by many social and economic factors, not biological diagnoses tied to race, sex, or age.
Not getting enough sleep is linked to higher risk of obesity, type 2 diabetes, high blood pressure, heart disease, stroke, anxiety and depression. Poor sleep is one visible sign that something in the body is out of balance. This link doesn't prove poor sleep directly causes those problems. The relationship often runs both ways and other factors play a role.

NHIS and BRFSS use different survey methods, so 2024 national numbers and 2022 state numbers cannot be compared directly.
Sleep length is only part of the story. Trouble falling asleep and trouble staying asleep have different causes, and need different fixes.
Trouble falling asleep

Self-reported over the past 30 days. These are not clinical diagnoses of insomnia.
Trouble falling asleep, trouble staying asleep, and short sleep, by age group.
Adults ages 50 to 64 reported the most trouble staying asleep.
Source: CDC NHIS, 2024
Age patterns describe groups, not individuals. Age is not a diagnosis.
Reported sleep trouble by sex, across three measures.
Women reported more trouble falling and staying asleep than men. Black adults reported higher rates of short sleep than several other groups in the 2024 survey (39.9% versus 28.4% among White adults).

Group differences reflect many factors. Sex is not a diagnosis here.

Biological noise
Mental and physical tension builds through the evening, delaying your body's ability to wind down.

This sequence is an example, not a universal model. Real cases often start elsewhere, or involve breathing, body clock timing, or medication.

12.9%
of U.S. adults used a sleep aid most days or every day (CDC NHIS, 2024).
Source: CDC NHIS, 2024 (sleep-aid use); Sleep Week clinical summary, 2026
Nearly 13% of adults used some sleep aid most days or every day in 2024. Using one does not mean it works.

Changing one thing at a time rarely shows what matters most for you. That is why we measure first.
Every chart works with mouse, keyboard, and touch. Each one offers a data table, a CSV download, and its source and year.
