Insomnia in US 2025
Sleep is fundamental to human health, yet millions of Americans struggle with insomnia every single night. The condition goes far beyond occasional restlessness, representing a persistent disorder that affects daily functioning, mental health, and overall quality of life. From difficulty falling asleep to waking up throughout the night, insomnia manifests in various forms and impacts different demographic groups in distinct ways. Understanding the scope and scale of this widespread sleep disorder through verified statistical data helps illuminate both the public health challenge it represents and the urgent need for effective interventions across American communities.
The landscape of insomnia in the US has evolved significantly over recent years, with researchers documenting troubling increases in prevalence across multiple age groups and populations. Government health surveys reveal that this sleep disorder extends beyond mere inconvenience, contributing to substantial healthcare costs, lost workplace productivity, and serious safety concerns. The economic burden alone reaches into hundreds of billions of dollars annually when accounting for direct medical expenses, absenteeism, and reduced performance at work. As medical professionals and public health experts examine the latest data, it becomes increasingly clear that insomnia represents one of the most significant yet underrecognized health challenges facing Americans today.

The statistics paint a sobering picture of insomnia’s impact across the United States. According to the Centers for Disease Control and Prevention’s National Health Interview Survey conducted in 2020, approximately 14.5% of American adults experienced trouble falling asleep most days or every day within the past month, while an even higher proportion—17.8%—struggled with staying asleep throughout the night. These figures translate to tens of millions of Americans whose nightly rest is consistently disrupted, leading to cascading effects on their daytime functioning and overall health. More recent data from the American Academy of Sleep Medicine confirms that approximately 10% of adults meet the strict diagnostic criteria for chronic insomnia disorder, while a significantly broader 30% to 40% of adults report experiencing insomnia symptoms at some point each year. Breaking this down further, 30% to 35% experience brief episodes of insomnia, 15% to 20% encounter short-term insomnia lasting under three months, and around 10% grapple with chronic insomnia occurring at least three times weekly for a minimum of three months.
The economic consequences of widespread insomnia are staggering and extend far beyond individual suffering. Recent research from RAND Corporation and other institutions places the total annual economic impact between $100 billion and $207.5 billion when accounting for indirect costs such as workplace productivity losses, absenteeism, accidents, and reduced performance. Scientists approximate that the collective impact of insomnia on the US workforce results in an economic burden of approximately $63 billion annually. Individuals with chronic insomnia lose an average of 45 to 54 days of workplace productivity each year. Particularly alarming are recent CDC statistics from 2022 showing that 30% to 46% of adults get insufficient sleep—defined as less than seven hours per night—with variation depending on the state. Data reveals that approximately 70 million Americans currently experience sleep problems. These numbers underscore how insomnia affects not just personal health but also represents a massive economic burden on employers, healthcare systems, and the broader American economy.
Gender Differences in Insomnia Prevalence in the US
| Gender Category | Trouble Falling Asleep | Trouble Staying Asleep |
|---|---|---|
| Women | 17.1% | 20.7% |
| Men | 11.7% | 14.7% |
| Women aged 20-39 | 16.7% | Data varies by study |
| Men aged 20-39 | 9.2% | Data varies by study |
| Overall gender prevalence ratio | Women 1.4 times more likely | Women significantly higher |
Data source: CDC National Health Interview Survey 2020, National Health and Nutrition Examination Survey (NHANES), NIH studies
The data reveals striking gender disparities in insomnia prevalence that persist across virtually all age groups and measurement criteria. According to CDC data from 2020, 17.1% of women reported trouble falling asleep most days or every day, compared to just 11.7% of men—representing nearly a 50% higher rate among women. The gap widens further when examining difficulty staying asleep, with 20.7% of women experiencing this problem versus 14.7% of men. Among younger adults aged 20 to 39 years, studies document that 16.7% of women report insomnia symptoms compared to 9.2% of men, indicating these disparities begin early in adulthood and continue throughout the lifespan. Research consistently demonstrates that women are approximately 1.4 times more likely than men to suffer from insomnia symptoms.
Multiple biological, psychological, and social factors contribute to these pronounced gender differences in insomnia. Women experience unique hormonal fluctuations throughout their lives—during menstrual cycles, pregnancy, postpartum periods, and menopause—that directly impact sleep architecture and quality. Studies indicate that adolescent girls become approximately 3 times more likely to experience insomnia than boys following puberty, when sex hormones surge. Beyond biological factors, women also report higher levels of pre-sleep arousal and worry, which are known perpetuating factors for insomnia. Social factors including caregiving responsibilities, which statistics show women spend twice as much time on compared to men, further compound sleep difficulties. Among adults aged 25 to 44 years with at least one child, 55% of women get less than 7 hours of sleep nightly compared to 38% of men, with women in this demographic sleeping approximately 30 minutes less per night than their male counterparts.
Age-Related Insomnia Patterns in the US
| Age Group | Trouble Falling Asleep | Trouble Staying Asleep |
|---|---|---|
| 18-44 years | 15.5% | 13.8% |
| 45-64 years | Data within range | 21.8% |
| 65+ years | 12.1% | 20.3% |
Data source: CDC National Health Interview Survey 2020
Age significantly influences insomnia patterns, though the relationship proves more complex than simple linear progression. CDC data from 2020 reveals that 15.5% of adults aged 18 to 44 years experience trouble falling asleep, a rate that actually decreases to 12.1% among those 65 years and older. This counterintuitive finding suggests younger adults face greater challenges initiating sleep, possibly related to higher stress levels, technology use, irregular schedules, and other modern lifestyle factors. However, the story changes dramatically when examining sleep maintenance—the ability to stay asleep throughout the night. Only 13.8% of adults aged 18 to 44 report trouble staying asleep, but this figure jumps substantially to 21.8% for those 45 to 64 years old and remains elevated at 20.3% for seniors 65 and older.
The divergent patterns between sleep onset and sleep maintenance difficulties across age groups reflect different underlying mechanisms and challenges. Younger adults struggling to fall asleep often face issues related to anxiety, racing thoughts, irregular work schedules, excessive screen time, and stimulant consumption late in the day. As individuals transition into middle age and beyond, physiological changes become increasingly influential. Declining hormone levels, increased prevalence of chronic health conditions, medication side effects, and changes in sleep architecture all contribute to more frequent nighttime awakenings. For older adults 65 and above, nearly half report some difficulty with sleep, making insomnia one of the most common health complaints in this demographic. The high rates of sleep maintenance insomnia in older populations carry particular concern because fragmented sleep has been linked to cognitive decline, increased fall risk, and reduced quality of life.
Socioeconomic Factors and Insomnia in the US
| Income Level (% of Federal Poverty Level) | Trouble Falling Asleep | Trouble Staying Asleep |
|---|---|---|
| Below 100% FPL | 21.9% | 22.1% |
| 100-199% FPL | Mid-range | Mid-range |
| 200%+ FPL | 12.6% | 16.9% |
| Education Level | Trouble Falling Asleep | Trouble Staying Asleep |
|---|---|---|
| Less than high school | 17.0% | 16.6% |
| High school diploma/GED | 15.5% | 18.1% |
| Some college | 16.7% | 19.5% |
| Bachelor’s degree or higher | 10.4% | 16.3% |
Data source: CDC National Health Interview Survey 2020
The relationship between socioeconomic status and insomnia demonstrates a clear and consistent gradient, with individuals facing economic hardship experiencing substantially higher rates of sleep difficulties. Adults living below the federal poverty level report trouble falling asleep at a rate of 21.9%—nearly double the 12.6% rate observed among those with family incomes at 200% or more of the poverty level. This stark disparity persists for sleep maintenance problems as well, with 22.1% of the poorest Americans struggling to stay asleep compared to 16.9% of their more affluent counterparts. The correlation between poverty and poor sleep likely operates through multiple pathways: financial stress and worry, unsafe or noisy housing conditions, irregular work schedules including night shifts, limited access to healthcare, and higher rates of chronic health conditions that disrupt sleep.
Educational attainment shows an interesting nonlinear relationship with insomnia prevalence. Those with a bachelor’s degree or higher report the lowest rate of trouble falling asleep at 10.4%, while all groups with less education hover between 15.5% and 17.0%. However, the pattern for staying asleep proves more complex, with adults having some college education reporting the highest rate at 19.5%, followed by those with a high school diploma at 18.1%. College graduates, despite their lower sleep onset problems, still experience sleep maintenance difficulties at 16.3%. This suggests that higher education may provide protective factors—such as less physically demanding work, more control over schedules, and better stress management resources—that particularly help with falling asleep. Yet the stresses associated with professional careers may still contribute to nighttime awakenings, preventing a complete protective effect.
Urban-Rural Differences in Insomnia Patterns in the US
| Urbanization Level | Trouble Falling Asleep | Trouble Staying Asleep |
|---|---|---|
| Large central metropolitan | 12.7% | 14.4% |
| Large fringe metropolitan (suburban) | Mid-range | Mid-range |
| Medium and small metropolitan | Mid-range | Mid-range |
| Nonmetropolitan (rural) | 17.1% | 22.4% |
Data source: CDC National Health Interview Survey 2020
Geographic residence patterns reveal significant urban-rural disparities in insomnia prevalence across the United States. Adults living in large central metropolitan areas—major cities—experience the lowest rates of both sleep initiation and maintenance problems, with only 12.7% reporting trouble falling asleep and 14.4% having difficulty staying asleep. In stark contrast, residents of nonmetropolitan or rural areas face substantially higher rates: 17.1% struggle to fall asleep and a striking 22.4%—nearly one in four adults—have trouble staying asleep through the night. This represents a difference of approximately 35% for sleep onset problems and 55% for sleep maintenance issues when comparing the most urban to the most rural areas.
Multiple factors likely contribute to the higher insomnia burden in rural America. Rural communities typically have more limited access to healthcare services, including specialists who treat sleep disorders, making diagnosis and treatment more difficult. Economic challenges are often more pronounced in rural areas, with higher poverty rates and fewer employment opportunities contributing to financial stress. The nature of rural occupations—often involving physically demanding work, agricultural schedules, or long commutes—may disrupt sleep patterns. Additionally, rural areas have fewer community resources for mental health support, and mental health conditions strongly correlate with insomnia. Limited access to behavioral sleep medicine specialists means rural residents with chronic insomnia are less likely to receive evidence-based treatments like cognitive behavioral therapy for insomnia (CBT-I). This geographic healthcare disparity represents a significant public health challenge requiring targeted interventions to ensure rural Americans receive adequate sleep disorder care.
Racial and Ethnic Disparities in Insomnia in the US
| Race/Ethnicity | Trouble Falling Asleep | Trouble Staying Asleep |
|---|---|---|
| Non-Hispanic White | 15.1% | 21.0% |
| Non-Hispanic Black | 13.7% | 15.4% |
| Hispanic | 14.3% | 10.6% |
| Non-Hispanic Asian | 8.1% | 8.7% |
Data source: CDC National Health Interview Survey 2020
Racial and ethnic patterns in insomnia prevalence present a complex picture that challenges simple assumptions about sleep health disparities. Non-Hispanic White adults report relatively high rates of 15.1% for trouble falling asleep and the highest rate of 21.0% for staying asleep. Non-Hispanic Black adults experience trouble falling asleep at 13.7% and staying asleep at 15.4%, while Hispanic adults report 14.3% and 10.6% respectively. Most strikingly, Non-Hispanic Asian adults demonstrate the lowest prevalence for both metrics—just 8.1% struggle to fall asleep and 8.7% have difficulty staying asleep, representing nearly half the rate observed in White adults for sleep maintenance problems.
These racial and ethnic differences in insomnia likely reflect a combination of biological, cultural, behavioral, and reporting factors rather than any single cause. Cultural attitudes toward sleep complaints and help-seeking behavior vary substantially across ethnic groups, potentially influencing who reports insomnia symptoms to healthcare providers or on surveys. Sleep habits and practices, including bedtime routines, co-sleeping arrangements, and the value placed on sleep, differ across cultures and may provide protective or risk factors. Access to healthcare and insurance coverage varies by race and ethnicity, affecting diagnosis rates. Additionally, chronic stressors including discrimination, occupational exposures, neighborhood conditions, and economic insecurity distribute unequally across racial groups and influence sleep health. It is important to note that while Asian Americans show lower rates of insomnia symptoms, this population also tends to report shorter sleep duration, suggesting potential cultural differences in how sleep problems are perceived and reported rather than necessarily indicating better overall sleep health.
Health Consequences and Comorbidities of Insomnia in the US
| Associated Health Condition | Increased Risk/Prevalence |
|---|---|
| Depression | 10 times more likely with insomnia |
| Anxiety disorders | 17 times more likely with insomnia |
| Cardiovascular disease | Significantly elevated risk |
| Type 2 diabetes | Increased association |
| Cognitive impairment | Higher rates |
| Obesity | Strong correlation |
| Falls and injuries | 29% to 90% increased odds |
Data source: Multiple NIH studies, American Academy of Sleep Medicine, CDC data
The relationship between insomnia and comorbid health conditions represents one of the most concerning aspects of this sleep disorder, with bidirectional relationships that can create vicious cycles of worsening health. Individuals with insomnia are 10 times more likely to suffer from depression and an astonishing 17 times more likely to experience anxiety disorders compared to good sleepers. The causal direction remains unclear—mental health conditions can precipitate insomnia, while chronic sleep deprivation can trigger or worsen psychiatric symptoms. Regardless of which comes first, the combination of insomnia and mental health disorders creates particularly severe impairment and requires integrated treatment approaches addressing both conditions simultaneously.
Physical health consequences of chronic insomnia extend across virtually every body system. Research has established links between persistent sleep problems and increased risk of cardiovascular disease, including hypertension, coronary artery disease, and stroke. The connection to metabolic disorders is equally troubling, with insomnia associated with elevated risk of type 2 diabetes and obesity through mechanisms involving hormonal dysregulation, increased appetite, and reduced physical activity due to daytime fatigue. Cognitive impacts range from impaired concentration and memory to increased risk of dementia in older adults. Falls represent a particularly serious concern, especially for older adults, with both insomnia itself and hypnotic medication use showing 29% to 90% increased odds of falling. Given that approximately 20.4% of nursing home admissions are attributed to sleep disturbances, and 91% of direct insomnia healthcare costs historically went toward nursing home care, the public health implications for an aging population are profound.
Recent Insufficient Sleep Trends in the US
| Insufficient Sleep Data | Statistical Finding | Year |
|---|---|---|
| Adults getting <7 hours sleep (Vermont) | 30% – lowest state percentage | 2022 |
| Adults getting <7 hours sleep (Hawaii) | 46% – highest state percentage | 2022 |
| National range insufficient sleep | 30% to 46% depending on state | 2022 |
| Adults not meeting sleep recommendations | One in three US adults | 2023 |
| Adults who report sleeping somewhat well or not well | 62% of adults worldwide | 2019 |
| College students with poor sleep quality | Up to 60% | 2017 |
| Older adults with chronic sleep problems | 40% to 70%, half undiagnosed | 2016 |
Data source: CDC Behavioral Risk Factor Surveillance System (BRFSS) 2022, CDC 2023, Philips Global Sleep Survey 2019, academic studies
Geographic variation in insufficient sleep patterns reveals significant disparities across American states according to the most recent CDC data. The 2022 Behavioral Risk Factor Surveillance System found that the percentage of adults getting less than the recommended seven hours of sleep ranged dramatically from a low of 30% in Vermont to a high of 46% in Hawaii. This represents more than a 50% relative difference between the best and worst-performing states, suggesting that regional factors—including economic conditions, work schedules, cultural attitudes toward sleep, healthcare access, and environmental factors—play substantial roles in population sleep health. The fact that even in the best-performing state nearly one-third of adults fail to meet basic sleep recommendations underscores the national scope of this public health challenge.
The breadth of insufficient sleep extends beyond just those with diagnosed insomnia disorders. CDC data from 2023 confirms that one in three American adults regularly don’t get enough sleep, representing more than 100 million people when extrapolated to the total adult population. Among specific subpopulations, the rates are even more concerning: up to 60% of college students have poor sleep quality, and between 40% and 70% of older adults have chronic sleep problems, with approximately half of these cases going undiagnosed. International comparisons reveal this is not solely an American phenomenon, with 62% of adults worldwide reporting they sleep somewhat well or not at all well. The consistency of high rates across diverse populations and measurement methods confirms that insufficient sleep represents a fundamental challenge to modern public health that extends well beyond clinical insomnia diagnoses.
| Workplace Impact Metric | Statistical Finding |
|---|---|
| Annual productivity days lost per person | 45 to 54 days with chronic insomnia |
| Total US productivity loss annually | 252.7 to 367 million days |
| Annual cost of lost work performance | $63.2 to $91.7 billion (net costs) |
| Percentage due to presenteeism | Approximately two-thirds |
| Percentage due to absenteeism | Approximately one-third |
| Annual workplace accidents | 274,000 insomnia-related |
| Cost per insomnia-related accident | Average $32,062 |
| Total accident costs | $31.1 billion annually |
| GDP loss to chronic insomnia | 0.64% to 1.31% of national GDP |
Data source: RAND Corporation studies, American Insomnia Survey, multiple workplace productivity studies
The workplace burden of insomnia represents one of the most economically significant yet underappreciated impacts of this sleep disorder. Research involving thousands of American workers documents that individuals with chronic insomnia lose between 45 and 54 days of productivity annually, translating to more than two months of impaired work performance each year. When extrapolated across the US workforce, this amounts to a staggering 252.7 to 367 million lost workdays annually. The economic value of this lost productivity reaches between $63.2 billion and $91.7 billion per year after controlling for comorbid conditions, with some estimates placing the total workplace burden even higher when including all direct and indirect effects. To put this in perspective, chronic insomnia reduces national economic output by approximately 0.64% to 1.31% of GDP—comparable to the economic impact of major chronic diseases.
Perhaps most striking is the distribution of productivity losses, with roughly two-thirds attributed to presenteeism—attending work while ill and functioning below capacity—rather than overt absenteeism. This means the majority of insomnia’s workplace costs involve employees physically present but cognitively impaired, making mistakes, working slowly, or struggling with decision-making due to sleep deprivation. The American Insomnia Survey found that insomnia-related workplace accidents and errors number approximately 274,000 annually, with an average cost of $32,062 per incident—significantly higher than the $21,914 average for non-insomnia-related incidents. Combined, these accidents carry a price tag of $31.1 billion each year. These statistics underscore that insomnia represents not just a personal health problem but a critical occupational health and safety issue with enormous economic ramifications for employers, industries, and the national economy.
Direct Healthcare Costs of Insomnia in the US
| Healthcare Cost Category | Annual Cost |
|---|---|
| Total direct costs (1995) | $13.9 billion |
| Prescription medications | Less than $1 billion (1995) |
| Over-the-counter medications | Portion of $1.97 billion (1995) |
| Alcohol as sleep aid | $339.8 million |
| Healthcare consultations | $191.2 million |
| Transportation to appointments | $36.6 million |
| Nursing home care | $11.96 billion (91% of direct costs) |
| 2002 hypnotic prescriptions filled | 27 million prescriptions worth $1.2 billion |
| Additional costs for elderly patients | $5,580 higher than matched controls |
| Additional costs for non-elderly patients | $4,220 higher than matched controls |
Data source: National Commission on Sleep Disorders Research, NIH studies, medical claims analyses
The direct medical costs of insomnia extend across numerous healthcare services and products, with the most comprehensive analysis from 1995 estimating total direct expenses at $13.9 billion. This figure, while dated, provides important baseline data, though the current costs have undoubtedly increased substantially when adjusted for inflation and population growth. Breaking down these expenses reveals interesting patterns: prescription medications for insomnia accounted for less than $1 billion, representing less than half of the total $1.97 billion spent on all substances used to treat insomnia, including over-the-counter sleep aids. Surprisingly, alcohol consumed as a sleep aid contributed $339.8 million to costs, highlighting the prevalence of self-medication with substances that actually worsen sleep quality over time.
The most striking finding is that $11.96 billion—representing 91% of total direct costs—was attributed to nursing home care for individuals with sleep disturbances. This massive expense reflects both the high prevalence of insomnia among elderly populations, with nearly half of people over 65 reporting sleep difficulties, and the fact that 20.4% of nursing home admissions were attributed to sleep problems. Healthcare utilization patterns reveal that insomnia patients have substantially higher costs across all service categories—physician visits, hospital stays, emergency department use, and pharmacy expenses—than individuals without sleep complaints. Medical claims data shows insomnia patients aged 65 and older incur an additional $5,580 in healthcare expenses per six months compared to matched controls, while non-elderly patients face an extra $4,220 in costs. By 2002, Americans filled 27 million prescriptions for hypnotic sleep medications valued at approximately $1.2 billion, demonstrating the substantial pharmaceutical component of insomnia treatment costs.
Workplace Impact and Productivity Loss from Insomnia in the US
| Medication Usage Metric | Statistical Finding |
|---|---|
| Women using medications (2005-2006) | 13.3% |
| Men using medications (2005-2006) | 8.9% |
| Women using medications (peak 2013-2014) | 17.0% |
| Men using medications (peak 2013-2014) | 15.2% |
| Prescription hypnotics filled annually | 27 million prescriptions (2002) |
Data source: National Health and Nutrition Examination Survey (NHANES) 2005-2018
Medication use for insomnia has shown interesting temporal patterns over the past two decades, with significant gender disparities and fluctuating trends. Data from the National Health and Nutrition Examination Survey reveals that in 2005-2006, 13.3% of women used medications commonly prescribed for insomnia compared to just 8.9% of men, demonstrating the higher treatment-seeking behavior among women consistent with their higher insomnia prevalence. Over the subsequent years, medication use increased substantially for both genders, peaking in 2013-2014 at 17.0% for women and 15.2% for men. This upward trend likely reflected growing awareness of insomnia as a treatable condition, increased availability of newer sleep medications, and greater willingness among both patients and providers to address sleep problems pharmacologically.
Following the 2013-2014 peak, medication use decreased slightly in subsequent years, possibly reflecting growing concerns about long-term use of hypnotic medications, increased awareness of adverse effects including next-day impairment and fall risk, regulatory warnings about certain sleep medications, and growing interest in non-pharmacological treatments like cognitive behavioral therapy for insomnia (CBT-I). The absolute number of prescriptions filled tells part of the story: in 2002, Americans filled 27 million prescriptions for hypnotic sleep medications worth approximately $1.2 billion. However, these figures likely underestimate total medication use because they don’t capture over-the-counter sleep aids, off-label use of other medications for sleep, or self-medication with alcohol or other substances. The persistent gender gap in medication use reflects the broader pattern of women experiencing higher insomnia rates and being more likely to seek medical treatment for sleep problems.
Insomnia Trends Over Time in the US
| Time Period | Prevalence | Population Impact |
|---|---|---|
| 2002 | 17.5% | 37.5 million adults |
| 2007 | Mid-range increase | Growing population affected |
| 2012 | 19.2% | 46.2 million adults |
| Relative increase (2002-2012) | +8.0% | +8.7 million additional adults |
| Age-adjusted prevalence increase | 17.4% to 18.8% | Accounting for demographic changes |
Data source: National Health Interview Survey (NHIS) 2002, 2007, 2012
Temporal trends in insomnia prevalence demonstrate a troubling increase in sleep problems across the United States population over the first decades of the 21st century. The unadjusted prevalence of insomnia or trouble sleeping rose from 17.5% in 2002, representing 37.5 million adults, to 19.2% by 2012, affecting 46.2 million adults—an 8.0% relative increase and nearly 9 million additional Americans experiencing sleep difficulties within just one decade. Even after adjusting for age distribution changes in the population, the prevalence increased significantly from 17.4% to 18.8%, confirming that these trends reflect genuine increases in insomnia rates rather than simply demographic shifts toward older age groups more prone to sleep problems.
Multiple factors likely contributed to this decade-long increase in insomnia rates. Rising obesity rates, which jumped substantially during this period, correlate strongly with sleep disorders including insomnia. The increasing prevalence of diabetes showed an especially noteworthy relationship, with adults with diabetes exhibiting particularly marked increases in insomnia. Occupational factors including workplace stress and shift work became more common, disrupting natural sleep-wake cycles. The proliferation of electronic devices and 24-hour connectivity likely played a role, with smartphones becoming ubiquitous and blurring boundaries between work and personal time while exposing users to sleep-disrupting blue light late into the evening. Economic stress from the 2008 financial crisis and subsequent recession may have contributed to worry and anxiety that interfere with sleep. Significant increases were present across multiple age brackets including 18-24, 25-34, 55-64, and 65-74 year-olds, both men and women, and among White and Hispanic populations, indicating broad-based rather than isolated trends.
