New research is revealing why a tired brain can still refuse to sleep \u2014 and why retraining it may sometimes matter as much as sedating it.<\/h2>\n\n\n\n

All day, you are exhausted. Getting out of bed is difficult, and by afternoon you are reaching for coffee. On the way home, you promise yourself that tonight you will finally go to bed early. But when you get into bed, something strange happens: you are no longer sleepy. Tomorrow\u2019s work appears in your head, followed by an unanswered message and perhaps something embarrassing you said years ago.<\/p>\n\n\n\n

You check your phone for a minute, and a minute becomes twenty. Then you look at the clock: 1:47 a.m.<\/strong> That is when perhaps the worst thought arrives \u2014 \u201cEven if I fall asleep right now, I only have five hours left.\u201d From that moment, you are no longer simply waiting for sleep. You are trying to make it happen, and sleep seems to move even farther away.<\/p>\n\n\n\n

How can someone be completely exhausted and still be unable to sleep? The answer may begin with a distinction most of us rarely make: being tired and being ready to sleep are not the same thing.<\/strong><\/p>\n\n\n\n

Young Adults Are Struggling to Fall Asleep<\/h2>\n\n\n\n

Insomnia is hardly just an older person\u2019s problem. Data released by the U.S. National Center for Health Statistics in April 2026 found that 30.5% of American adults slept less than seven hours per day on average<\/strong> in 2024. More strikingly, 18.3% of adults ages 18 to 34 reported trouble falling asleep most days or every day<\/strong>, compared with 12.8% among adults 65 and older. In that survey, difficulty falling asleep actually declined with age.<\/p>\n\n\n\n

That does not mean younger people have worse sleep in every respect. Older adults were more likely to report trouble staying asleep. But the difficulty of simply getting to sleep<\/strong> appears to be particularly common among younger adults. For a generation that carries work, entertainment, relationships, news and social life in a device beside the pillow, the question feels increasingly familiar: why can a young, exhausted body still have a brain that refuses to shut down?<\/p>\n\n\n\n

A Tired Body Can Still Have an Alert Brain<\/h2>\n\n\n\n

Sleep is not simply what happens when the body runs out of energy. The longer we stay awake, the more pressure for sleep generally builds, while our circadian clock helps determine when the brain expects wakefulness and when it expects sleep. Yet researchers studying chronic insomnia increasingly focus on another process: hyperarousal<\/strong> \u2014 a state in which the body may be lying still while the brain remains unusually alert.<\/p>\n\n\n\n

Worry, planning, replaying conversations, monitoring the clock and wondering whether sleep will come can all become part of this cycle. A 2026 analysis of a randomized trial involving 290 adults with chronic insomnia<\/strong> found that digital cognitive behavioral therapy for insomnia, or CBT-I, was associated at three months particularly with reductions in sleep-related worry, dissatisfaction with sleep and difficulty relaxing. Other improvements appeared to spread indirectly through these core arousal-related changes.<\/p>\n\n\n\n

The idea is important because it changes the question. An exhausted person may not necessarily need to become even more tired. In some cases, the more useful target may be the brain that has remained too alert for too long.<\/p>\n\n\n\n

Then Comes the Phone<\/h2>\n\n\n\n

When sleep does not come, many of us reach for the object beside the bed. It is tempting to reduce the problem to a familiar villain \u2014 blue light<\/strong> \u2014 but a smartphone is much more than a source of light. It is a conversation, a television, a newsstand, a workplace, a shopping mall and an almost limitless supply of new information.<\/p>\n\n\n\n

A person who once might have become bored enough to fall asleep can now reach practically the entire world without lifting their head from the pillow. The body may be saying that the day is over, while the phone continues to tell the brain that something else is happening. For an already activated brain, that endless stream of novelty can make the transition from wakefulness to sleep even harder.<\/p>\n\n\n\n

Your Bed Can Learn the Wrong Lesson<\/h2>\n\n\n\n

Another problem can develop when insomnia continues for weeks or months. Night after night, you lie awake in bed, scrolling, working, worrying and calculating how many hours of sleep remain. Gradually, the bed can become associated not only with sleep but also with frustration, alertness and effort.<\/p>\n\n\n\n

This is one reason stimulus control<\/strong> is a central part of CBT-I. Rather than spending long periods awake in bed struggling to force sleep, the approach tries to rebuild the association between the bed and actual sleep. The basic idea is simple: go to bed when sleepy, and if you remain awake long enough to become frustrated, leave the bed for a quiet activity in dim light and return when drowsiness comes back. The goal is not to punish insomnia. It is to teach the brain again that the bed is primarily a place where sleep happens.<\/p>\n\n\n\n

In 2026, Researchers Put Digital CBT-I Against Zolpidem<\/h2>\n\n\n\n

This year brought an especially interesting experiment. On August 18, 2026, researchers reported an exploratory randomized controlled trial directly comparing a five-week digital CBT-I program with zolpidem<\/strong>, one of the best-known prescription insomnia drugs. At week five, the digital CBT-I group reduced subjective sleep-onset latency by an average of 20.65 minutes<\/strong>, while the zolpidem 5 mg group improved by 22.42 minutes<\/strong>. The difference between the two groups was not statistically significant.<\/p>\n\n\n\n

Five weeks after treatment ended, the digital CBT-I group showed a stronger trend toward sustained improvement. But that later difference also did not<\/strong> reach statistical significance. Just as importantly, this was a very small exploratory study, so it cannot establish that digital therapy is as good as, or better than, zolpidem for the general population. The researchers themselves called for larger confirmatory studies.<\/p>\n\n\n\n

Still, the study raises a compelling question: what if part of the future of insomnia treatment is not simply finding a stronger sleeping pill, but teaching the brain how to sleep again?<\/strong><\/p>\n\n\n\n

The Evidence Is Larger Than One Small Study<\/h2>\n\n\n\n

That question does not rest on one trial. A 2026 model-based network meta-analysis examined 73 randomized controlled trials involving 14,465 participants<\/strong> and found a clear nonlinear relationship between the duration of digital CBT-I and improvement in insomnia severity. In the model, benefits tended to plateau beyond roughly 300 total treatment minutes, while approximately 250 minutes emerged as a promising treatment duration.<\/p>\n\n\n\n

This does not mean that everyone needs precisely 250 minutes of treatment. It does show, however, how far digital CBT-I has moved beyond generic advice such as avoiding coffee or turning off the phone. Researchers are now studying its dose-response relationship much as they would other therapeutic interventions.<\/p>\n\n\n\n

That distinction matters. Sleep hygiene and CBT-I are not the same thing.<\/strong> Sleep hygiene can support better sleep, but CBT-I addresses the behavioral and cognitive processes that may perpetuate chronic insomnia: spending excessive time awake in bed, fearing another bad night, trying too hard to sleep and developing patterns that reinforce wakefulness.<\/p>\n\n\n\n

What About Sleeping Pills?<\/h2>\n\n\n\n

Prescription sleep medications, including zolpidem, can be appropriate and useful for some patients. The point is not that medication is \u201cbad\u201d and behavioral therapy is \u201cgood.\u201d The more useful question is whether medication is being used at the right dose, for the right person, and whether the insomnia itself is also being treated.<\/p>\n\n\n\n

A 2026 pilot study called the SEDATIVE trial<\/strong> explored exactly that combination. Participants who had been taking sleep medications for at least three months received pharmacist-led supervised deprescribing alongside clinician-supervised CBT-I. The study was small and primarily designed to test feasibility, so its results should not be generalized to everyone. But its underlying idea is important: reducing sleep medication and treating insomnia do not have to be separate projects.<\/strong><\/p>\n\n\n\n

Instead of simply removing a pill and hoping for the best, clinicians may be able to combine gradual medication reduction with strategies that help the brain rebuild healthier sleep patterns.<\/p>\n\n\n\n

If You Take Zolpidem, Do Not Simply Cut the Dose Yourself<\/h2>\n\n\n\n

The FDA has warned that zolpidem can remain in the bloodstream the next morning at levels high enough to impair activities requiring full alertness, including driving, even when a person feels fully awake. For immediate-release zolpidem, the FDA lowered the recommended starting dose for women from 10 mg to 5 mg<\/strong> and recommends that clinicians consider the lower 5 mg dose for men as well. For extended-release zolpidem, the lower recommended dose is 6.25 mg.<\/p>\n\n\n\n

But that does not<\/strong> mean someone currently prescribed 10 mg should simply cut the medication in half tonight. The FDA specifically advises people already taking 10 mg or 12.5 mg to continue the prescribed dose until they have spoken with a health professional about how to proceed safely. The useful question to bring to a clinician is not \u201cCan I just stop?\u201d but rather: \u201cAm I taking the lowest effective dose, and could CBT-I eventually help me need less?\u201d<\/strong><\/p>\n\n\n\n

What Can You Actually Do Tonight?<\/h2>\n\n\n\n

There are several practical changes that fit the same science. Try to keep your morning wake time reasonably consistent, even after a poor night, because the wake time helps anchor the body clock. Go to bed when you are genuinely sleepy rather than simply because the clock says it is bedtime, and avoid spending long periods awake in bed trying to force sleep.<\/p>\n\n\n\n

If you are lying awake and becoming frustrated, get out of bed for a while, keep the environment dim and quiet, and return when sleepiness comes back. Move caffeine earlier in the day if you regularly use it late. Give your phone somewhere else to spend the night if possible, not because a single look at a screen automatically causes insomnia, but because an alert brain does not need an endless supply of stimulation at midnight.<\/p>\n\n\n\n

Most importantly, if insomnia persists, ask specifically about CBT-I<\/strong>, rather than assuming that a few sleep-hygiene tips are the same thing. And if you use prescription sleep medication, do not suddenly stop it or design your own taper. Discuss the dose and any reduction strategy with the clinician who prescribed it.<\/p>\n\n\n\n

The Strange Paradox of Sleep<\/h2>\n\n\n\n

Perhaps the cruelest thing about insomnia is that sleep is one of the few things in life that can become harder the more desperately we try to achieve it. We can force ourselves to exercise, work or eat, but we cannot simply order the brain to sleep.<\/p>\n\n\n\n

That is what makes the current research so interesting. Scientists are not only asking which chemical can make a person sleep. They are increasingly asking what keeps an exhausted brain awake, and whether that brain can relearn how to let go.<\/strong><\/p>\n\n\n\n

The person staring at the ceiling at two in the morning may not need to become more tired. They may need something very different: a brain that finally understands that the day is over.<\/strong><\/p>\n\n\n\n

TENVER VIEW<\/h2>\n\n\n\n

Sleep should not become a nightly contest between you and your brain. The emerging science of insomnia suggests that sometimes the answer may be less about forcing sleep and more about removing the conditions that keep the brain awake.<\/p>\n\n\n\n

You cannot command yourself to sleep. But you may be able to teach your brain that it no longer needs to keep trying to stay awake.<\/strong><\/p>\n\n\n\n
