What chronic insomnia actually is

Chronic insomnia is not occasional poor sleep. The DSM-5 diagnostic definition requires difficulty initiating sleep, maintaining sleep, or waking too early with inability to return to sleep, on three or more nights per week, for at least three months, with a clear negative effect on daytime functioning. A single difficult night is not chronic insomnia, and neither is the normal variability in sleep quality that everyone experiences.

A study published in BMC Psychiatry in 2021, examining the general population of Qatar, found that approximately ten percent of adults met diagnostic criteria for insomnia disorder. A 2024 study published in Scientific Reports examining Arab men in Jordan identified links between insomnia and anxiety, dietary patterns, and sleep habits. These figures suggest that clinical insomnia is common in the region and affects a substantial proportion of the population.

Chronic insomnia has two main presentations: sleep onset insomnia, where lying down and trying to sleep is consistently unsuccessful, and sleep maintenance insomnia, where falling asleep is possible but staying asleep is not. Many people experience both simultaneously. In both cases, the nervous system behaves as though it is on alert precisely at the moment sleep is wanted.

Why self-managed attempts usually fail

There is a very common vicious cycle. A person cannot sleep, spends longer in bed trying, the bed becomes mentally associated with frustration and wakefulness rather than rest, and the insomnia deepens. Many people compensate with long afternoon naps, which reduce the accumulated sleep pressure that makes falling asleep easy at night. Others shift their sleep timing at weekends, disrupting the biological clock that regulates when the body is ready to sleep.

The behaviours that seem helpful often sustain the insomnia. Watching television or using a phone until the last moment in bed, then attempting to force sleep, then becoming anxious when it does not happen within a few minutes: this is a loop that feeds insomnia rather than resolving it. The insomnia itself becomes a source of performance anxiety that keeps the nervous system in a state of heightened arousal at the one time when it needs to disengage.

The traditional solution is sleeping medication. It is effective in the short term but its fundamental problem is that it does not address the patterns causing the insomnia. It bypasses them temporarily. When the medication stops, the same patterns reassert themselves.

The risk of sleeping pills available in pharmacies

Benzodiazepines such as diazepam, nitrazepam, and closely related sleeping medications create physical dependence within a few weeks of regular use. A major review published in the journal Addiction in 2011 described this phenomenon in detail and noted that many patients were not adequately warned of this risk when the drugs were first prescribed. The body adapts to the presence of the drug, increasing doses are needed for the same effect, and when the drug is stopped, insomnia returns in a more severe form known as rebound insomnia.

In many Arab countries, anxiolytics, sedatives, and sleep aids are available without a prescription or with one that is easy to obtain. This means dependence develops over months or years without any medical oversight, and discontinuation becomes increasingly difficult. Patients who were prescribed a sleeping pill for a specific short-term problem find themselves unable to stop.

Newer sleeping pills such as zolpidem and over-the-counter antihistamine sleep aids carry different concerns. Zolpidem has documented effects on memory and behaviour during the night. Antihistamine sleep aids lose their effectiveness rapidly with tolerance. There is no sleeping pill that is safe for long-term use without medical supervision and monitoring.

What is CBT-I and why does it work?

Cognitive Behavioral Therapy for Insomnia (CBT-I) is a structured programme that addresses the mechanisms keeping insomnia going rather than just its symptoms. It typically runs over five to eight sessions and can be delivered by a therapist, through a self-guided workbook, or via a validated digital application. It is the recommended first-line treatment in the guidelines of major health bodies including the NHS, the American Academy of Sleep Medicine, and the European Sleep Research Society.

A systematic review and meta-analysis of nineteen clinical trials published in the Annals of Internal Medicine in 2015 found that CBT-I produced significant improvements in every key sleep measure: time to fall asleep, number of night-time awakenings, and time awake after sleep onset. Critically, the improvements persisted after the treatment ended, unlike the effect of medication which stops when the medication stops.

CBT-I is built from several tools used together: sleep restriction to rebuild sleep pressure, stimulus control to re-establish the bed as a sleep cue rather than a wakefulness cue, relaxation techniques, correction of inaccurate beliefs about sleep that maintain anxiety, and relapse prevention. A 2024 network meta-analysis published in JAMA Psychiatry confirmed that sleep restriction and stimulus control are the two most active components.

Sleep restriction: the hardest and most powerful tool

Sleep restriction sounds counterintuitive but is the strongest single component of CBT-I. The idea is this: instead of spending eight or nine hours in bed trying and mostly failing to sleep, you reduce the time permitted in bed to match only your actual current sleep duration. If you are genuinely sleeping five hours from eight hours in bed, you begin by permitting five and a half hours in bed and no more.

The HABIT trial published in The Lancet in 2023 showed that sleep restriction delivered by nurses in primary care significantly improved insomnia outcomes compared with usual care. This demonstrates that the technique does not require a specialist psychologist to be applied effectively. It can be learned and implemented with adequate guidance.

In the first week, most people feel more tired because the body is building the sleep debt needed to restore adequate sleep pressure. This is intentional and expected. As sleep efficiency, the ratio of actual sleep to time in bed, improves, the permitted time in bed is extended by fifteen minutes each week until the person reaches their optimal sleep duration without difficulty.

How to apply sleep restriction step by step

  1. 1Keep a sleep diary for one week and record actual sleep time (not time in bed)
  2. 2Set a fixed daily wake time and keep it every day including weekends, without exception
  3. 3Set a bedtime so that time in bed does not exceed actual sleep hours by more than thirty minutes
  4. 4Only go to bed when you feel genuinely sleepy, not just tired or because it is your usual time
  5. 5If you have not fallen asleep within roughly twenty minutes, get out of bed and sit quietly elsewhere
  6. 6Each week your sleep efficiency improves, add fifteen minutes to the permitted time in bed

Stimulus control: retraining the brain

Stimulus control aims to break the learned association that has formed between the bed and wakefulness, frustration, and anxiety. Its central rule is that the bed is used only for sleep and intimacy. Not for phones, not for television, not for extended reading, not for lying awake thinking about the day. Every other activity happens outside the bed.

The second element is what is sometimes called the twenty-minute rule. If you are in bed and have not fallen asleep after approximately twenty minutes, get up and sit in another room in dim light doing something quiet and non-stimulating, such as reading a physical book or simply sitting with your thoughts. Return to bed only when sleepiness is obvious. This step is difficult at three in the morning but it is the mechanism by which the brain is gradually reconditioned.

The 2024 JAMA Psychiatry network meta-analysis found that of all CBT-I components, stimulus control and sleep restriction produced the largest and most consistent effects. Relaxation training, sleep hygiene education, and cognitive work added value, but these two are the core that drives the majority of improvement.

The beliefs that keep insomnia going

An important part of CBT-I involves identifying and examining beliefs about sleep that sustain anxiety around bedtime. One of the most common is the conviction that exactly eight hours is required and that anything less will make tomorrow unmanageable. In reality, sleep need varies substantially between individuals and across age, and many adults function well on six to seven hours. The anxiety about achieving a precise number often does more harm than the actual sleep deficit.

Another common belief is that one poor night will cause failure the next day in every area of life. Research consistently shows that the cognitive and physical effects of a single bad night are substantially less severe than most insomnia sufferers expect. The anticipatory anxiety about those effects, however, is a genuine problem because it activates the nervous system at the precise moment when disengagement is needed.

The cognitive component of CBT-I teaches you to notice these automatic thoughts rather than accepting them at face value. A thought such as 'I will never sleep properly again' can be examined: how many times was that thought present and yet sleep eventually came? This objective examination reduces the physiological arousal that otherwise peaks at bedtime.

Starting CBT-I without access to a therapist

Self-guided CBT-I is both possible and documented to be effective. Digital programmes such as Sleepio and Somryst are validated by clinical trials and guide you through the full protocol. Self-help books designed around the CBT-I framework have similarly shown effectiveness in randomised trials. The key is starting with the two core tools: a week of sleep diary logging followed by implementing sleep restriction and stimulus control simultaneously.

Setting the right expectation makes it easier to persist through the difficult first weeks. The first two weeks of sleep restriction usually feel harder, not easier, than before treatment began. This is normal and means the technique is working by creating the sleep pressure needed to restore efficient sleep. Results typically begin to appear by week three or four and continue improving through week six to eight.

If the insomnia is accompanied by symptoms of depression, significant anxiety, or if a partner reports loud snoring and periods of stopped breathing during sleep, a medical assessment is needed before starting self-guided CBT-I. Secondary insomnia caused by an underlying medical or psychiatric condition needs that condition addressed first. Sleep apnoea in particular is a separate disorder that CBT-I alone does not treat.

What to expect across a course of CBT-I

  1. Weeks 1 to 2 Increased daytime tiredness from sleep restriction; this is expected and means it is working
  2. Weeks 3 to 4 Sleep efficiency begins to improve, faster sleep onset, fewer night-time awakenings
  3. Weeks 5 to 6 Marked improvement in sleep quality and reduced bedtime anxiety
  4. After week 8 Stable results that continue to consolidate; permitted time in bed increased gradually toward personal optimum

When to see a doctor before trying CBT-I

There are situations where medical assessment should come before self-guided CBT-I. If your partner tells you that you snore loudly or stop breathing briefly during sleep, this suggests sleep apnoea, which is a distinct disorder requiring its own investigation. Sleep apnoea causes fragmented sleep by design and cannot be corrected by CBT-I alone. It is also associated with cardiovascular risk and deserves proper evaluation.

If your insomnia began with a new medication or alongside a physical illness, correcting that underlying cause may be the entire solution. Corticosteroids, certain stimulant medications, and some antidepressants cause insomnia as a side effect, and changing the medication regimen may resolve the sleep problem without any further intervention.

If insomnia is accompanied by persistent low mood, intense anxiety that is difficult to control, or intrusive thoughts, speaking with a doctor or mental health professional is important. Insomnia and depression frequently coexist and reinforce each other, and treatment may need to address both simultaneously. Insomnia that is part of a bipolar disorder picture in particular needs specialist management.

The Sihtak app lets you track your sleep quality every day and identify the patterns that improve or disrupt it, which is the core data that CBT-I is built on.

Frequently asked questions

How long before CBT-I produces results?

Most people notice meaningful improvement by week three or four. The full course typically runs five to eight weeks. The first two weeks are usually the most difficult as sleep restriction creates short-term tiredness. Results built through CBT-I are substantially more durable than those from medication, persisting after the treatment ends rather than disappearing when it stops.

Can I take a sleeping pill while doing CBT-I?

Some guidelines permit this in certain situations under medical supervision. Generally it is better to separate them because sleeping pills reduce the natural pressure that sleep restriction is designed to build. If you want to continue a sleeping pill during CBT-I, discuss it with your doctor and aim for the lowest effective dose with a clear plan for tapering.

Does stimulus control mean I can never read in bed?

Strictly yes, during active treatment. Brief quiet reading before sleep is accepted by some practitioners once insomnia has resolved and sleep is consistently efficient. During the first weeks of treatment, the rule is that everything except sleep and intimacy happens outside the bed. This speeds up the reconditioning of the bed as a sleep signal.

Is CBT-I appropriate for older adults?

Yes, and it is particularly preferred for older adults because sleeping pills carry substantially higher risks in this age group including falls, cognitive impairment, and next-day sedation. Sleep restriction is adjusted for older adults with the awareness that sleep need naturally decreases with age, and the target sleep duration is calibrated accordingly.

Can insomnia come back after CBT-I is complete?

Yes, particularly during periods of high stress. This is why CBT-I includes relapse prevention: recognising early warning signs of returning insomnia and applying the tools promptly. Many people conduct a brief week or two of sleep restriction as soon as they notice a deterioration, rather than waiting until full chronic insomnia has re-established itself.

Does melatonin help with chronic insomnia?

Melatonin is most clearly useful for circadian rhythm disorders such as jet lag or shift work, where the body clock is misaligned with the desired sleep time. For chronic insomnia in which the sleep window is appropriately timed but sleep itself is difficult, melatonin produces modest and inconsistent results in trials. It does not address the conditioned arousal that CBT-I treats.

When does insomnia become an emergency?

Insomnia alone is rarely a medical emergency. However, if it is accompanied by thoughts of self-harm or suicide, seek mental health care promptly. If sleeplessness is accompanied by severe chest pain, shortness of breath, or repeated episodes of rapid heart rate waking you from sleep, urgent medical assessment is needed to exclude a physical cause.
