You likely have insomnia if you regularly have trouble falling asleep, staying asleep, or waking up too early, even though you give yourself enough time in bed, and the poor sleep is affecting how you feel or function during the day. Clinicians diagnose chronic insomnia when these problems happen at least three nights a week for at least three months. If your sleep trouble is newer or less frequent, it may be short-term insomnia, which is common after stress, illness, or a schedule change and often resolves on its own.
Almost everyone has a bad night now and then, so it can be hard to tell whether you are dealing with a few rough weeks or a sleep disorder that deserves treatment. This guide walks through the signs of insomnia, the criteria doctors actually use, a simple self-check and two-week sleep diary you can start tonight, the conditions that look like insomnia but are not, and when it makes sense to see a professional. It is written for adults 18 and older, including people in Miami and across Florida.
Insomnia is a sleep disorder in which you have persistent difficulty falling asleep, staying asleep, or getting sleep that feels restorative, despite having a reasonable opportunity to sleep. That last part matters. Someone who sleeps five hours because they stay up working until 2 a.m. and wake at 7 for work is sleep deprived. Someone who goes to bed at 11, lies awake until 2, and then cannot fall back asleep after waking at 4 has insomnia. The difference is whether your body and brain will let you sleep when you give them the chance.
Insomnia is one of the most common health complaints in adults. In a widely cited review in the Journal of Clinical Sleep Medicine, Thomas Roth estimated that about 30% of adults report symptoms of disrupted sleep, and roughly 10% have insomnia with the daytime consequences that meet criteria for a diagnosis. The National Heart, Lung, and Blood Institute (NHLBI) describes two broad forms:
Insomnia can also be described by when in the night the problem happens: sleep-onset insomnia (trouble falling asleep), sleep-maintenance insomnia (waking up during the night and struggling to get back to sleep), and early-morning awakening (waking hours before your alarm and being unable to return to sleep). Many adults have a mix. Early-morning awakening in particular is worth mentioning to a clinician, because it is a classic feature of depression.
The signs below come from the symptoms clinicians ask about during a sleep evaluation. One or two on an occasional basis is normal. Several, most nights, for weeks at a time, is a pattern worth taking seriously.
There is no single official cutoff, but sleep clinicians often use about 30 minutes as a practical rule of thumb. If you routinely lie in bed for half an hour or more before falling asleep, especially while your mind races, that points toward sleep-onset insomnia. (If racing thoughts are the main problem, our guide to racing thoughts at night covers why the brain revs up at bedtime.)
Brief awakenings are a normal part of sleep, and most people do not remember them. With insomnia, you wake fully, check the clock, and spend 30 minutes or more trying to get back to sleep, often more than once a night.
Waking at 4 or 5 a.m. with no chance of drifting off again, when you intended to sleep until 7, is a hallmark of insomnia. It is also common in depression and with heavy evening alcohol use.
You may technically be asleep for several hours, yet wake up feeling as if you barely slept. Unrefreshing sleep is a common insomnia complaint, but it can also be a sign of sleep apnea, so it is worth discussing with a clinician rather than assuming.
People with insomnia often feel fatigued and worn down but are not actually sleepy enough to fall asleep during the day. If you are dozing off in meetings or at red lights, that suggests a different sleep problem, which we cover below.
Trouble focusing, forgetting appointments, making more mistakes at work, or feeling foggy are among the most common daytime effects of insomnia. Our article on brain fog causes explains how poor sleep and mental health conditions both affect thinking.
Sleep loss lowers your threshold for frustration and makes worries feel bigger. Mood changes are both a consequence of insomnia and, in many cases, part of what drives it.
One of the clearest signs of chronic insomnia is that sleep itself becomes a source of stress. You may calculate how many hours you will get if you fall asleep "right now," avoid evening plans to protect your sleep, or feel your heart rate climb as you get into bed.
Many people with chronic insomnia fall asleep easily on the couch or in a hotel but lie wide awake in their own bed. This happens because the brain has learned to associate the bed with being awake and frustrated, a process called conditioned arousal. It is one of the main targets of cognitive behavioral therapy for insomnia.
Psychiatrists and sleep physicians diagnose insomnia disorder using criteria from the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR). In plain language, a diagnosis requires all of the following:
A helpful way to remember the chronic threshold is "3 and 3": three nights a week for three months. Importantly, insomnia can be diagnosed alongside depression, anxiety, chronic pain, or other conditions. Older guidance often treated insomnia as merely a symptom of something else; current guidance recognizes that it frequently deserves its own treatment, even when another condition is present. The American Psychiatric Association and the American Academy of Sleep Medicine both offer patient-friendly overviews of these criteria.
Answer the questions below based on a typical week over the past month. This is not a diagnostic test, but it can help you organize what you have noticed before you talk with a clinician.
How to read your answers: If you answered yes to questions 4, 5, 6, and 7 plus at least one of questions 1 through 3, your pattern is consistent with chronic insomnia, and an evaluation is worthwhile. If you answered yes to question 7 but no to question 6, the first step may simply be protecting more time for sleep. If the pattern is newer than three months, you may be dealing with short-term insomnia, which is still worth addressing early so it does not become chronic.
In a clinical setting, providers often use validated questionnaires such as the Insomnia Severity Index (ISI), a brief seven-item scale that rates sleep difficulty, satisfaction, and daytime impact, to measure severity and track progress over time.
Memory is unreliable when it comes to sleep. People with insomnia tend to underestimate how much they sleep, and people who are simply short on time often overestimate it. A sleep diary is the single most useful thing you can bring to an appointment, and it is the foundation of cognitive behavioral therapy for insomnia. Fill it out each morning for two weeks:
| What to record | Example entry | Why it matters |
|---|---|---|
| Time you got into bed | 10:45 p.m. | Shows how much opportunity you gave yourself |
| About how long it took to fall asleep | 60 minutes | Identifies sleep-onset insomnia |
| Number and length of awakenings | 2 times, about 40 minutes total | Identifies sleep-maintenance insomnia |
| Final wake time and time out of bed | 5:10 a.m. / 6:30 a.m. | Reveals early waking and time spent awake in bed |
| Estimated total sleep | About 4.5 hours | Lets you calculate sleep efficiency |
| How rested you felt (1 to 5) | 2 | Tracks sleep quality, not just quantity |
| Caffeine, alcohol, naps, exercise, medications | Coffee at 3 p.m., 2 glasses of wine | Surfaces habits that may be disrupting sleep |
Sleep efficiency is your total sleep time divided by the total time you spent in bed. In the example above, 4.5 hours of sleep across nearly 7.75 hours in bed is a sleep efficiency of about 58%. Healthy sleepers usually sit around 85% or higher. A consistently low number is one of the clearest objective markers of insomnia, and it is exactly what CBT-I is designed to improve.
Several conditions mimic insomnia, and treating them as insomnia can make things worse. Sleeping pills, for example, can be risky for someone with untreated sleep apnea. Here is how the most common look-alikes differ:
| Condition | Key clue | How it differs from insomnia |
|---|---|---|
| Insomnia | Tired but wired; cannot sleep even with time to do so | The reference point |
| Insufficient sleep | Falls asleep fast, sleeps long on weekends | The problem is not enough time in bed, not inability to sleep |
| Obstructive sleep apnea | Loud snoring, gasping, morning headaches, dozing off during the day | Breathing pauses fragment sleep; requires a sleep study |
| Restless legs syndrome | Uncomfortable urge to move the legs in the evening, relieved by moving | Physical sensations, not racing thoughts, keep you awake |
| Delayed sleep-wake phase | Cannot sleep before 2 or 3 a.m., but sleeps normally if allowed to wake late | Your body clock is shifted; sleep itself is normal |
| Shift work disorder | Poor sleep tied to night, early, or rotating shifts | Driven by working against your circadian rhythm |
| Hypomania or mania | Sleeping three or four hours and feeling energized, not tired | A decreased need for sleep, which is a mood symptom, not insomnia |
That last row is especially important. People with insomnia want to sleep and feel exhausted when they cannot. A person in a hypomanic or manic episode of bipolar disorder often feels they do not need sleep and has unusual energy, fast speech, or racing ideas. That combination calls for a psychiatric evaluation rather than a sleep aid. For a broader look at other conditions, see our overview of sleep disorders and their mental health connection.
Sleep researchers often describe insomnia using the "3 P" model: predisposing factors that make you vulnerable (a naturally light sleeper, a tendency to worry), precipitating factors that trigger it (stress, illness, a new job), and perpetuating factors that keep it going (spending extra time in bed, napping, scrolling at night, relying on alcohol). Perpetuating factors are why insomnia so often outlasts its original cause, and they are also the most changeable. Common contributors include:
Insomnia and mental health problems feed each other. Poor sleep makes emotions harder to regulate, and anxiety or depression make sleep harder to come by. The relationship is strong enough that insomnia is now considered a risk factor for depression, not just a symptom of it. A meta-analysis of longitudinal studies by Baglioni and colleagues (Journal of Affective Disorders, 2011) found that people with insomnia who were not depressed at the start had about twice the risk of developing depression later (odds ratio 2.60) compared with good sleepers.
Here is how insomnia commonly shows up alongside specific conditions:
Because of this overlap, a psychiatric evaluation can be one of the most efficient ways to sort out insomnia. Treating an underlying anxiety or mood disorder often improves sleep, and treating the insomnia directly often improves mood.
It is reasonable to start with good sleep habits on your own, and our guide to sleep hygiene is a good place to begin. But sleep hygiene alone is rarely enough for chronic insomnia. Consider an evaluation if:
If poor sleep comes with thoughts of hopelessness or of harming yourself, please do not wait for a routine appointment. Call or text 988 to reach the Suicide and Crisis Lifeline, or call 911.
The good news is that insomnia is very treatable, and the most effective treatment does not depend on long-term medication.
CBT-I is the recommended first-line treatment for chronic insomnia in adults. The American College of Physicians' 2016 clinical practice guideline recommends that all adults with chronic insomnia receive CBT-I as the initial treatment, and the American Academy of Sleep Medicine's 2021 guideline gives multicomponent CBT-I a strong recommendation. CBT-I is a structured program, usually four to eight sessions, that combines sleep restriction (temporarily matching time in bed to actual sleep), stimulus control (re-training the brain to link bed with sleep), cognitive work on unhelpful beliefs about sleep, and relaxation techniques. In a meta-analysis published in Annals of Internal Medicine (Trauer et al., 2015), CBT-I shortened the time to fall asleep by about 19 minutes, reduced time awake after falling asleep by about 26 minutes, and improved sleep efficiency by nearly 10 percentage points, with benefits that tend to last after treatment ends.
Medication can help in the short term or when CBT-I is not enough or not accessible. The American Academy of Sleep Medicine's pharmacologic guideline reviews options such as orexin receptor antagonists, certain "Z-drugs," ramelteon, and low-dose doxepin, each matched to whether the problem is falling asleep or staying asleep. When insomnia occurs alongside depression or anxiety, a psychiatrist may choose a medication that treats both. Some commonly prescribed options, such as trazodone for sleep or Seroquel for sleep, are used off-label and carry their own trade-offs, which is why they are best chosen with a prescriber who knows your full history. Over-the-counter options like melatonin help some circadian problems but are generally less effective for chronic insomnia.
Addressing co-occurring anxiety, depression, PTSD, ADHD, or a medication side effect is often what finally lets sleep improve. This is where a psychiatric approach differs from a quick sleep-aid prescription: the goal is to understand why you are not sleeping, not just to sedate you.
At Elevate Psychiatry, our psychiatrists and psychiatric nurse practitioners evaluate adults 18 and older who are struggling with sleep. A visit typically includes a review of your sleep pattern and sleep diary, screening for anxiety, depression, bipolar disorder, ADHD, and trauma, a look at your current medications and substances, and screening for signs of sleep apnea or other sleep disorders that may need a referral for a sleep study. From there we build a plan that may include CBT-I-based strategies, therapy, medication management, or treatment of a co-occurring condition.

Occasional bad nights are normal, especially during stress. Insomnia is more likely if you have trouble falling asleep, staying asleep, or waking too early at least three nights a week, despite giving yourself enough time in bed, and it is affecting how you feel or function during the day. When that pattern lasts three months or longer, clinicians call it chronic insomnia.
It is a simple way to remember the threshold for chronic insomnia: sleep problems that happen at least three nights per week for at least three months. Sleep trouble that is newer or less frequent may be short-term insomnia, which often improves once the trigger passes but is still worth addressing early.
A self-check and a two-week sleep diary can show whether your pattern is consistent with insomnia, but a formal diagnosis requires a clinician. A psychiatrist or sleep physician will also rule out look-alike conditions such as sleep apnea, restless legs syndrome, a shifted body clock, medication side effects, or the decreased need for sleep seen in bipolar disorder.
Insomnia disorder is listed in the DSM-5-TR, the diagnostic manual psychiatrists use, and it is closely tied to mental health. It often occurs alongside anxiety, depression, PTSD, and ADHD, and research shows that insomnia roughly doubles the risk of later developing depression. That is why psychiatrists commonly evaluate and treat it.
Usually not. Insomnia is diagnosed from your history, a sleep diary, and questionnaires. A sleep study is recommended when another sleep disorder is suspected, such as obstructive sleep apnea, which is suggested by loud snoring, gasping during sleep, morning headaches, or falling asleep during the day without meaning to.
Cognitive behavioral therapy for insomnia (CBT-I) is the recommended first-line treatment for chronic insomnia in adults, according to guidelines from the American College of Physicians and the American Academy of Sleep Medicine. Medication can help in some cases, and treating co-occurring anxiety, depression, or other conditions often improves sleep as well.
