Insomnia in Black Adults: Why Sleep Is a Health-Equity Issue

Insomnia is trouble falling asleep, trouble staying asleep, or waking too early and not being able to get back to sleep, paired with daytime fallout: fatigue, low mood, trouble concentrating, or feeling on edge. When it happens a few nights a week for at least three months, it is chronic insomnia, and chronic insomnia is a treatable medical condition, not a personal failing or a fact of life. Black adults carry more of this burden and get less help for it. In 2024, 40.2% of non-Hispanic Black adults slept less than 7 hours a night, compared with 28.9% of white adults, according to the CDC's National Center for Health Statistics.

The disparity is consistent across decades of data and it is widening. A study of national survey data from 2004 to 2018 found Black adults were persistently less likely than white adults to get the recommended hours of sleep, and the gap grew over time. The drivers are largely outside the bedroom. Researchers point to chronic stress, the vigilance that comes with experiencing racism, shift work and second jobs, and neighborhood conditions like noise, light, crowding, and safety concerns that interrupt sleep.

Racism itself shows up in the data on sleep. A 2020 study in Sleep Health of nearly 1,500 people with diagnosed insomnia found that experiences of racial discrimination accounted for about 61% of the difference in insomnia severity between Black and white participants. Once the researchers accounted for discrimination, race was no longer a significant predictor of how bad the insomnia was. An earlier study found perceived racial discrimination was linked to more than double the odds of sleep disturbance (odds ratio 2.62) and daytime fatigue (odds ratio 2.07). The proposed mechanism is the kind of looping, anticipatory worry that keeps the brain switched on at night.

Short and poor sleep is wired into the same chronic diseases that already fall heaviest on Black Americans. The American Heart Association names sleep duration as one of its eight core measures of cardiovascular health and recommends 7 to 9 hours a night for adults. Sleeping under 7 hours is associated with higher rates of obesity, high blood pressure, type 2 diabetes, heart disease, and stroke. Poor sleep also worsens mood and anxiety. When a population already faces higher rates of hypertension and diabetes, sustained sleep loss is not a minor add-on; it compounds the risk. That is why treating insomnia is a cardiometabolic and mental-health intervention, not a luxury.

Chronic insomnia usually has more than one driver. Common ones include:

• Stress and racism-related vigilance. A mind that stays alert for threat does not power down on schedule. Persistent anxiety is one of the most common engines of insomnia.
• Shift work and multiple jobs. Rotating or overnight schedules fight the body's clock and shorten sleep, and Black workers are overrepresented in shift-heavy jobs.
• Environment. Light, traffic and street noise, heat, and crowded housing all fragment sleep.
• Untreated sleep apnea. Breathing that stops and starts overnight causes repeated awakenings that can read as insomnia. It is common and badly underdiagnosed in Black patients.
• Caffeine, alcohol, screens, and pain. Late caffeine and alcohol both wreck sleep architecture, blue light from phones suppresses melatonin, and untreated pain keeps you up.

Sorting out which of these applies to you is the first step, because the fix is different for each.

For chronic insomnia, the recommended first treatment is cognitive behavioral therapy for insomnia, known as CBT-I. The American College of Physicians recommends CBT-I as the initial treatment for all adults with chronic insomnia, and the American Academy of Sleep Medicine makes the same first-line recommendation. CBT-I works at least as well as sleeping pills in the short term, has fewer side effects, and unlike medication its benefits last after treatment ends.

CBT-I is a short, structured program, usually 4 to 8 sessions, that retrains the relationship between your body and your bed. It targets the habits and thoughts that keep insomnia going: spending too long awake in bed, irregular sleep and wake times, clock-watching, and the anxious belief that one bad night ruins the next day. It is delivered by trained therapists, and there are well-studied digital and app-based versions for people who cannot reach an in-person clinician. If anxiety is feeding the insomnia, treating the anxiety matters too; our guide to anxiety symptoms in Black adults covers how that shows up and what helps. A therapist who offers CBT-I can often be reached through online therapy.

Good sleep habits help, but on their own they rarely cure chronic insomnia. The basics worth doing: keep a consistent wake time every day including weekends, get morning daylight, cut caffeine after early afternoon, avoid alcohol as a sleep aid, keep the bedroom dark, cool, and quiet, and stop using the bed for scrolling or working so your brain links the bed with sleep. If you cannot fall asleep within about 20 minutes, get up, do something calm in low light, and return when you feel sleepy. These steps are part of CBT-I, but the structured therapy is what moves chronic insomnia, which is why sleep-hygiene tips alone often disappoint.

Melatonin is a hormone, not a sedative. It can help shift a delayed body clock, for example in shift workers or jet lag, but the evidence that it treats chronic insomnia is weak, and over-the-counter products are not tightly regulated, so the dose on the label is often not what is in the bottle. Prescription sleep aids can help in the short term and during a crisis, but they carry real downsides: next-day grogginess, fall and accident risk, dependence with long-term use, and rebound insomnia when stopped. Guidelines reserve them for short-term use and pair them with CBT-I, not as a standalone long-term fix. If you are already taking a sleep medication nightly, do not stop abruptly; ask a clinician about tapering while starting CBT-I.

Loud snoring, gasping or choking awake, witnessed pauses in breathing, and daytime sleepiness despite a full night in bed are signs of obstructive sleep apnea, not ordinary insomnia. This matters because Black adults are more likely to have moderate or severe sleep apnea and far less likely to get it diagnosed. One analysis found only a small fraction of Black participants with moderate or severe sleep apnea had ever received a diagnosis. Untreated apnea drives high blood pressure, heart disease, stroke, and diabetes, so it should not be missed. If these signs fit you, read our guide to sleep apnea signs in Black adults and ask about a sleep study.

Start with a clinician who will take your sleep seriously and screen for apnea, depression, and anxiety rather than reaching straight for a prescription. Ask directly: "Can you refer me for CBT-I?" and "Should I be evaluated for sleep apnea?" Bring a one-week sleep log (when you went to bed, when you actually slept, night wakings, wake time) so the visit starts with data. If finding a clinician who understands your context matters to you, you can find a Black primary care or sleep clinician in our directory. Insurance often covers both a sleep study and CBT-I; ask the office to check before you go.
