Explanation
Core Causes of Insomnia
Insomnia is a sleep disorder characterised by difficulty falling asleep, staying asleep, or experiencing restorative sleep.
It may be acute or chronic and is often associated with stress, anxiety, lifestyle factors, or underlying health conditions.
Poor sleep can affect cognitive function, mood, and physical health.
From a holistic perspective, insomnia reflects dysregulation of the nervous system and sleep-wake cycles.

Why it happens
Possible causes & risk factors
Insomnia usually comes from a mix of factors rather than a single cause. These are common contributors — not certainties.
Biology & temperament
Genetic factors and natural differences in circadian rhythm regulation may make some people more prone to difficulty sleeping.
Stress & life events
Anxiety, worry, and ongoing life stress are among the most commonly reported contributors to both short-term and persistent insomnia.
Health & substances
Underlying conditions such as chronic pain, hormonal changes, or mood disorders may interfere with the ability to fall or stay asleep.
Sleep & lifestyle
Irregular sleep schedules, excessive screen time before bed, and stimulant use in the evening are frequently associated with poor sleep onset and quality.
What happens in the body
How this may affect the body
Insomnia can involve several of the body’s systems. These are common patterns researchers describe — how they show up varies from person to person.
Nervous System
neurologicalInsomnia involves dysregulation of two fundamental sleep mechanisms: the homeostatic drive (adenosine accumulation that builds sleep pressure throughout the day) and the circadian rhythm (the suprachiasmatic nucleus's 24-hour clock). When the bed becomes associated with wakefulness through learned associations, cortical hyperarousal maintains wakefulness even when sleep pressure is high — the defining neurological paradox of chronic insomnia.
Endocrine System
biochemicalPoor sleep disrupts the hormonal cascade that governs recovery and restoration. Growth hormone, secreted primarily during deep NREM sleep, is reduced. Cortisol rhythms are reversed — elevated at night, blunted in the morning. Ghrelin (hunger hormone) increases while leptin (satiety hormone) decreases, explaining weight dysregulation in chronic insomnia. Melatonin secretion timing becomes disrupted, particularly with evening light exposure.
Process
Diagnosis & Assessment
- Review sleep historyA practitioner typically asks about sleep onset time, number of nightly awakenings, total sleep duration, and how long the pattern has persisted.
- Assess daytime impactEvaluating how poor sleep affects mood, concentration, energy, and daily functioning helps clarify severity and guides next steps.
- Explore contributing factorsStress levels, caffeine and alcohol use, medications, screen habits, and underlying anxiety or health conditions are commonly reviewed as possible contributors.
- Rule out other sleep disordersA practitioner may consider conditions such as sleep apnea or restless leg syndrome, sometimes recommending a sleep study if symptoms suggest a deeper issue.
Management
Treatment & Management
Cognitive Behavioral Therapy for Insomnia
CBT-I is widely regarded as a first-line approach that may help people identify and shift thought patterns and behaviors contributing to poor sleep.
Sleep restriction and stimulus control
Structured behavioral techniques used within CBT-I that some people find helpful for rebuilding a stronger association between bed and restful sleep.
Prescription sleep medications
A doctor may discuss short-term use of certain medication classes, such as sedative-hypnotics or low-dose antidepressants, depending on individual circumstances.
Relaxation and mindfulness practices
Techniques such as progressive muscle relaxation, guided breathing, and mindfulness meditation may support a calmer pre-sleep state for some individuals.
Herbal and supplement options
Some people explore options like melatonin, valerian root, or magnesium; some practitioners suggest these may support sleep onset, though individual responses vary.
Self-Care
Lifestyle & Self-Care
Cut caffeine and alcohol by early afternoon
Both caffeine and alcohol can disrupt sleep architecture. Some people find avoiding them after 2 p.m. may support more restful, uninterrupted sleep through the night.
Keep a consistent sleep and wake schedule
Going to bed and waking at the same time each day, even on weekends, may support your body's natural sleep-wake rhythm over time.
Dim screens and lights an hour before bed
Reducing exposure to blue light in the evening may support your body's natural melatonin release, helping signal that it is time to wind down.
Build a calming pre-sleep wind-down routine
Some people find that a consistent routine of light stretching, reading, or slow breathing before bed helps ease the transition from wakefulness to sleep.
Reserve your bed for sleep only
Avoiding work, screens, or eating in bed may help your mind associate the bedroom with rest, which some practitioners suggest can reduce the time it takes to fall asleep.
The Evidence
Evidence context for insomnia
What research says about insomnia, how it works, and where professional support fits in.
Overall pictureStrong evidence base
Insomnia is one of the most researched sleep conditions
Cognitive behavioural therapy for insomnia (CBT-I) has a strong evidence base and is widely considered a first-line approach. Complementary strategies such as sleep hygiene and relaxation techniques are broadly supported as helpful additions.
What the research showsCBT-I has the strongest evidence base for insomnia, with sleep hygiene and relaxation techniques also well supported.
CBT-I is consistently supported across clinical guidelines internationally as an effective approach for chronic insomnia. Sleep hygiene education and stimulus control are widely recommended. Relaxation-based techniques show moderate supporting evidence. Complementary approaches are commonly used alongside, though evidence varies by method.
How insomnia is understood clinicallyInsomnia involves disruption to the brain's sleep-wake regulation systems, with learned arousal playing a key role.
Sleep is governed by two systems: homeostatic sleep pressure and the circadian rhythm. In insomnia, the bed can become associated with wakefulness, creating a cycle of cortical hyperarousal. Hormonal disruption follows — including altered cortisol patterns and reduced growth hormone secretion — affecting mood, cognition, and physical recovery over time.
A holistic lens on sleepInsomnia is often understood as a whole-system response, not just a nighttime problem.
Holistic perspectives view insomnia as a reflection of broader nervous system dysregulation, often shaped by stress, lifestyle, and emotional patterns. Approaches such as mindfulness, breathwork, and body-based practices are commonly used to support the conditions for sleep, rather than targeting sleep directly. Evidence for these varies but is growing.
Approaches commonly usedA range of options exist, from structured psychological therapy to lifestyle and complementary practices.
CBT-I remains the most evidence-supported approach and is available in individual, group, and digital formats. Mindfulness-based programmes, relaxation techniques, and sleep hygiene practices are widely used as complements. Some people also explore breathwork or body-based practices. The most suitable combination depends on individual circumstances and should be discussed with a qualified practitioner.
When to seek professional supportPersistent insomnia, severe fatigue, or significant impact on daily functioning warrant professional assessment.
Insomnia that continues for more than a few weeks, causes significant daytime impairment, or is accompanied by mood disturbance, breathing irregularities during sleep, or unexplained physical symptoms should be evaluated by a qualified health professional. Underlying conditions — including anxiety, depression, or sleep-related breathing disorders — may require specific assessment and support.
