Always Tired? New CDC Data Show Nearly 3 in 4 U.S. Adults Feel Exhausted

A new national report reveals how common fatigue is—and when tiredness deserves more attention

The headline number: tiredness is widespread

If you have wondered why so many people seem exhausted, new federal data offer a striking answer. A report from the Centers for Disease Control and Prevention’s National Center for Health Statistics found that nearly three in four U.S. adults felt very tired or exhausted at least some days during the previous three months.

The report, dated September 9, 2026, analyzed responses from the 2024 National Health Interview Survey. Adults were asked how often they had felt very tired or exhausted in the past three months.

The results were:

  • 28.5% said they never felt very tired or exhausted.
  • 54.9% experienced those symptoms some days.
  • 10.7% experienced them most days.
  • 5.9% experienced them every day.

The researchers classified the final two groups—people tired most days or every day—as having frequent fatigue. Together, they represented 16.6% of U.S. adults, or roughly one in six.

That distinction matters. Feeling worn out occasionally is not the same as experiencing fatigue repeatedly enough to affect daily life.

Younger adults reported more frequent fatigue

One of the report’s more unexpected findings was that frequent fatigue was highest among younger adults rather than older adults.

Among adults ages 18–34, 19.5% reported frequent fatigue. The percentage generally decreased with age and was 12.9% among adults age 65 and older.

The survey cannot explain why this pattern occurred. It does not show that age itself caused fatigue, and it was not designed to identify whether sleep, work schedules, caregiving, health conditions, stress, medications, or other factors were responsible.

Still, the finding challenges the idea that persistent exhaustion is simply a normal part of getting older. Younger adults can experience substantial fatigue, too.

Women were more likely than men to report frequent fatigue

Frequent fatigue was reported by 20.0% of women and 13.0% of men.

The report also found differences among racial and ethnic groups. American Indian and Alaska Native adults had the highest reported prevalence at 25.5%. The estimates were 18.0% among White adults, 17.3% among Black adults, 12.9% among Hispanic adults, and 9.1% among Asian adults.

These percentages describe population patterns, not an individual person’s likelihood of having a particular illness. Differences can reflect many overlapping influences, including access to healthcare, income, work and living conditions, disability, stress, and underlying health.

For many people, fatigue lasted much of the day

Among adults with frequent fatigue, 45.3% said their symptoms lasted some of the day the last time they occurred. Another 34.5% said fatigue lasted most of the day, while 20.2% said it lasted all day.

Intensity was also substantial. More than one-third—38.8%—described their fatigue as “a lot.” Nearly half, 46.8%, placed it between “a little” and “a lot.”

These findings help separate ordinary end-of-day sleepiness from a symptom that may consume hours and interfere with normal functioning.

Fatigue often appeared alongside other difficulties

The report did not determine what caused fatigue, but it found that frequent fatigue commonly occurred alongside difficulties in other areas of functioning.

Overall, 89.1% of adults with frequent fatigue reported at least one co-occurring functional difficulty. About half, 50.9%, reported difficulty in three or more functional areas, compared with 16.9% of adults who did not have frequent fatigue.

Work and social activities were affected as well:

  • 36.0% of adults with frequent fatigue reported limits in the kind or amount of work they could do, compared with 15.3% of adults without frequent fatigue.
  • 16.2% reported some difficulty participating in social activities.
  • 8.5% reported a lot of difficulty with social participation.
  • 4.3% said they could not participate in social activities at all.

This does not mean fatigue alone caused every limitation. It does show that frequent fatigue can be part of a broader health and functioning burden.

What persistent fatigue can—and cannot—tell you

Fatigue is a symptom, not a diagnosis. A national survey can show how common it is, but it cannot determine why a particular person feels exhausted.

Possible contributors can include insufficient or disrupted sleep, infection, anemia, thyroid problems, medication effects, chronic pain, heart or lung conditions, diabetes, depression, anxiety, and many other issues. Sometimes several factors overlap.

Avoid trying to diagnose the cause from a single symptom or an online checklist. Instead, pay attention to the pattern:

  1. How long has the fatigue been present?
  2. Is it improving, stable, or getting worse?
  3. Does rest help?
  4. Is it interfering with work, driving, exercise, relationships, or self-care?
  5. Did it begin after an illness or medication change?
  6. Are there other symptoms, such as shortness of breath, pain, fever, bleeding, mood changes, or unexplained weight change?

Writing down these details can make a healthcare visit more useful.

A practical first step: review the basics without blaming yourself

Before assuming the worst—or dismissing the problem—review factors that can often worsen fatigue:

  • Sleep duration and whether sleep feels restorative.
  • Irregular work hours or repeated nighttime awakenings.
  • Alcohol, caffeine, and other substances that disrupt sleep.
  • Meals, hydration, and long periods without eating.
  • New prescriptions, over-the-counter products, or supplements.
  • Recent infection or a flare of an existing condition.
  • Stress, anxiety, low mood, and caregiving demands.

This review is not a substitute for medical care, and fatigue should not automatically be blamed on lifestyle. It is simply a way to give your clinician a clearer picture.

When to contact a healthcare professional

Consider scheduling medical advice if fatigue:

  • Persists despite adequate sleep and reasonable self-care.
  • Is getting worse or has no clear explanation.
  • Regularly interferes with work, school, exercise, or daily tasks.
  • Began after a new medication or dose change.
  • Occurs with symptoms of sleep apnea, such as loud snoring, gasping, or morning headaches.
  • Accompanies persistent sadness, loss of interest, severe anxiety, or other major mood changes.

Seek prompt or emergency care for fatigue accompanied by chest pain, trouble breathing, fainting, confusion, one-sided weakness, severe dehydration, uncontrolled bleeding, black or bloody stools, or thoughts of self-harm.

Key Takeaways

  • Nearly three in four U.S. adults reported feeling very tired or exhausted at least some days during the previous three months.
  • Frequent fatigue—symptoms most days or every day—affected 16.6%, or about one in six adults.
  • Frequent fatigue was more common among women and adults ages 18–34.
  • More than one-third of adults with frequent fatigue reported work limitations.
  • The survey describes population patterns; it does not identify the cause of an individual’s fatigue.
  • Persistent or disruptive fatigue deserves attention, especially when it appears with other symptoms.
