A new Centers for Disease Control and Prevention report finds that nearly three in four U.S. adults say they experience persistent tiredness or low energy — a figure with implications for public health, workplaces and primary care. The scale of reported fatigue underscores growing strain on health services and raises fresh questions about links to post-infectious conditions, mental health and everyday life demands.
What the CDC found
The federal analysis, based on a national survey, shows widespread complaints of ongoing exhaustion across age groups and regions. While the report does not point to a single cause, its authors highlight persistent symptoms that affect daily functioning and quality of life for a large share of the population.

For clinicians and policymakers, the finding matters because fatigue is often a marker for treatable conditions but can also signal complex, long-term illness patterns that require coordinated care.
Key drivers identified by experts
- Chronic medical conditions — such as diabetes, heart disease or autoimmune disorders, which commonly produce low energy.
- Mental health — depression and anxiety frequently include fatigue as a core symptom.
- Sleep disturbances — insomnia, obstructive sleep apnea and irregular schedules reduce restorative rest.
- Post-infectious syndromes — ongoing symptoms after viral infections, including long COVID, are increasingly recognized contributors.
- Medications and substance use that list tiredness as a side effect.
Why this matters now
High rates of reported fatigue translate into concrete consequences: higher demand for medical visits, impaired work performance, increased safety risks on roads and at job sites, and added strain on caregivers. For employers, widespread low energy can affect productivity and absenteeism. For health systems, it raises the need for better screening and pathways to manage multi-factorial symptoms.
Implications for care and policy
Experts say the CDC data point to several priorities: improve primary-care screening for persistent tiredness, expand access to mental health and sleep medicine services, and develop clearer referral routes when patients present with complex, multi-system complaints.
At a population level, addressing social determinants — housing, employment stability and access to affordable health care — will be important because these factors shape sleep, stress and chronic disease risk.
Practical steps for people feeling persistently tired
Not every case of tiredness points to a serious disorder, but sustained fatigue deserves attention. Consider the following actions:
- Talk with a primary-care clinician about the duration and pattern of symptoms.
- Review medications and substances that could be contributing to tiredness.
- Ask about screening for sleep disorders and mental-health conditions.
- Track sleep habits and daily energy levels to help clinicians pinpoint causes.
- Seek workplace adjustments if fatigue affects safety or performance.
While more research is needed to untangle the drivers of this widespread fatigue, the CDC’s findings are a timely reminder that persistent low energy is not just a personal issue — it is a public-health concern with ripple effects across the economy and the health-care system.
