Insomnia encompasses difficulty falling asleep (sleep onset insomnia), difficulty staying asleep with frequent or prolonged nocturnal waking (sleep maintenance insomnia), and early morning waking. It may be short-term (acute, often stress-related) or chronic (persisting for three or more months, occurring at least three nights per week). Chronic insomnia affects approximately 10–15% of the adult population and is associated with increased risk of depression, anxiety, cardiovascular disease, and metabolic dysfunction. It frequently co-occurs with other conditions rather than being a standalone problem, requiring consideration of contributory factors including hyperarousal, cognitive-behavioural patterns, medications, pain, and underlying mental health conditions.
The Evidence
What research and clinical practice say about difficulty falling or staying asleep, and where to find support.
Well-researched symptom with effective first-line options
Insomnia is one of the most studied sleep complaints, with strong evidence supporting behavioural and psychological approaches. Understanding contributing factors is key, as insomnia frequently co-occurs with other health conditions rather than existing in isolation.
Seek assessment if insomnia is accompanied by loud snoring or witnessed pauses in breathing, severe low mood or thoughts of self-harm, or significant daytime impairment affecting safety such as driving. Acute onset following trauma with persistent hyperarousal also warrants professional support rather than self-directed approaches alone.
CBT-I is the recommended first-line approach and outperforms medication for long-term outcomes. It combines sleep restriction, stimulus control, and cognitive restructuring. Short-term medications exist but carry risks of tolerance and dependence with extended use. Melatonin has specific support for circadian rhythm-related difficulties.
Long-term use of benzodiazepines or z-drugs for insomnia is not recommended due to dependence and tolerance risk. Sleep restriction — a component of CBT-I — requires careful management in people with bipolar disorder, as sleep deprivation can trigger mood episodes. Always discuss medication options with a qualified health professional.
CBT-I is available via therapists, digital programmes, and guided self-help. Complementary approaches including herbal supports such as valerian, passionflower, and ashwagandha are widely used, though evidence varies. Traditional systems including TCM and Ayurveda offer frameworks for understanding sleep difficulties. Lifestyle factors — light exposure, routine, and stress — are emphasised across approaches.
TCM may interpret poor sleep through patterns such as heart fire or liver qi stagnation. Ayurvedic approaches may involve herbal support, self-massage, and dietary adjustment. These frameworks offer contextual meaning and practical rituals that some people find helpful. They are not substitutes for professional assessment where underlying conditions may be present.
If sleep difficulties have persisted for three or more months, are affecting mood, concentration, or daily safety, or are accompanied by other symptoms, a GP or sleep specialist can help identify contributing factors. A referral to a CBT-I trained therapist or sleep clinic may be appropriate. Gyfts does not replace professional assessment.
