When do bad nights become insomnia worth treating?
Occasional poor sleep is part of life. Insomnia deserves clinical attention when disturbed nights occur at least three nights a week for three months or more, together with daytime effects such as fatigue or poor concentration, and sooner when symptoms are severe. And the most effective first treatment for chronic insomnia is a structured therapy called CBT-I, not a sleeping tablet.
The Threshold
Bad nights,
and the clinical line
Everyone sleeps badly sometimes: before an exam, after a loss, in a new city. That is normal and needs no treatment. Clinically, chronic insomnia is defined by pattern and consequence: difficulty falling asleep, staying asleep or waking too early, at least three nights a week, for three months or longer, with daytime effects such as fatigue, poor concentration or irritability.
The daytime part matters as much as the nights. Some people sleep six hours and function well; that is a sleep pattern, not a disorder. It is the combination of disturbed nights and impaired days that marks the line where assessment becomes worthwhile.
The Signal
Insomnia is often
a messenger
Persistent insomnia frequently travels with something else. Depression and anxiety commonly coexist with it, but insomnia may still need direct treatment rather than being expected to disappear when the other condition improves. It can also point to non-psychiatric problems: loud snoring with pauses in breathing suggests sleep apnoea, while an irresistible urge to move the legs at night suggests restless legs syndrome.
Everyday chemistry matters too. Late caffeine, alcohol used as a sleep aid, erratic schedules and screens that push bedtime later all sustain insomnia. A good assessment maps all of this before reaching for any prescription, because treating the wrong cause produces frustrated patients and untreated problems.
The Evidence
Why therapy comes
before tablets
International guidelines, including those of the American Academy of Sleep Medicine and NICE in the UK, recommend cognitive behavioural therapy for insomnia (CBT-I) as the first-line treatment for chronic insomnia. CBT-I retrains the timing, associations and thinking patterns around sleep, and its benefits persist after treatment ends, a durability that medication has not been shown to match.
Medication can have a legitimate role for selected people, including short-term relief or when CBT-I is unavailable or insufficient. Benzodiazepines and related z-drugs can cause sedation, impaired driving and dependence, particularly with longer continuous use; other sleep medicines have different benefits and risks. If treatment for months has consisted only of repeated prescriptions, a fuller assessment is reasonable.
The Assessment
What a sleep-focused
consultation looks like
A psychiatric assessment of insomnia reconstructs your nights and days: when sleep changed, what it looks like hour by hour, what has been tried, mood, worry, substances and medical history, with screening for apnoea and restless legs. Where a sleep study is indicated, that is arranged; most insomnia, however, is diagnosed by careful history.
Treatment is then matched to the cause: CBT-I for chronic insomnia, treatment of depression or anxiety where they are driving the nights, referral where the problem is respiratory, and short-term medication only where it genuinely helps. The aim is not sedation; it is a sleep system that works on its own again.

If your nights have been broken for months, an assessment is a smaller step than it feels, and considerably smaller than another year of exhausted mornings.

Common Questions
Insomnia and treatment,
answered simply
How many hours of sleep do I actually need?
Most adults function best on roughly seven to nine hours, but the range is individual. The clinical question is not the number alone; it is whether your sleep leaves you restored. Consistently unrefreshing sleep with daytime impairment deserves assessment regardless of the hour count.
What is CBT-I?
Cognitive behavioural therapy for insomnia is a structured, short-term programme that corrects the schedules, associations and thought patterns that keep insomnia going. It is recommended as first-line treatment for chronic insomnia by major international guidelines, and its effects last beyond the end of treatment.
When is a sleep study needed?
A sleep study is considered when history suggests another sleep disorder, especially loud snoring with witnessed pauses, choking or gasping, marked daytime sleepiness, unusual movements or behaviours during sleep, or when the diagnosis remains uncertain. Straightforward chronic insomnia and typical restless legs syndrome are usually assessed clinically.
Can insomnia be treated online?
Largely, yes. The assessment is history-based and CBT-I adapts well to video consultation. Where examination or a sleep study is needed, that is arranged separately. Online care is not appropriate for emergencies.
Do sleeping tablets cause dependence?
Benzodiazepines and related z-drugs can cause sedation, impaired driving, falls, interactions and dependence. They may be appropriate for selected people, often for a limited period, but choice, dose and duration require individual assessment rather than a blanket assurance of safety.
