If you lie awake at night with a mind that will not stop, you are not alone. Sleep disruption is one of the most common presenting concerns among people with anxiety - and one of the most distressing. The experience of desperately wanting to sleep while your mind keeps generating worry, rehearsing tomorrow, or replaying today, is exhausting in a way that affects every part of life.

The anxiety-sleep cycle: why they reinforce each other

Anxiety and sleep problems share a biological pathway: the stress response. When the threat-detection system in the brain is activated - whether by a real external threat or by the cognitive loop of anxious worry - it triggers physiological arousal. Cortisol and adrenaline rise. Heart rate increases. The brain shifts toward vigilance. This is the opposite of the relaxed, low-arousal state needed for sleep onset.

People with anxiety often experience this arousal as a "switched-on" feeling at bedtime: thoughts speeding up rather than slowing down, a heightened sense of alertness, or physical restlessness (muscle tension, racing heart). Worry provides content for this arousal to latch onto. The mind reaches for problems to solve, scenarios to rehearse, or risks to catalogue - particularly at night, when there are no other demands competing for attention.

Poor sleep then worsens anxiety through several mechanisms:

• Reduced emotional regulation capacity: The prefrontal cortex, which provides top-down regulation of threat responses, is particularly sensitive to sleep deprivation. Insufficient sleep makes the brain's alarm system more reactive and the regulating system less effective.
• Heightened threat sensitivity: Sleep-deprived people show greater amygdala reactivity to negative stimuli - threats feel more threatening, worries feel more plausible.
• Lowered frustration tolerance and mood: Fatigue makes everything harder to cope with, and difficulty coping feeds back into worry.
• Secondary worry about sleep itself: Many people develop a second layer of anxiety specifically about sleep - worry about how much sleep they are getting, what tomorrow will be like if they do not sleep, or whether they will ever sleep normally again. This secondary anxiety becomes its own maintaining factor.

This cycle is well-documented in the clinical literature and is part of what makes anxiety-related insomnia respond well to psychological treatment: addressing the anxiety component helps the sleep, and addressing the sleep component helps the anxiety.

CBT-I: the evidence-based psychological treatment for insomnia

Cognitive Behavioural Therapy for Insomnia (CBT-I) is the leading psychological treatment for insomnia and is recommended as the first-line treatment by NICE (UK), the American Academy of Sleep Medicine, and the Australian Psychological Society. A 2023 Cochrane systematic review by Morin and colleagues confirmed that CBT-I produces significant, durable improvements in sleep onset latency, wake after sleep onset, sleep efficiency, and subjective sleep quality, with effects that persist at 6 and 12 months follow-up and are superior to sleep medications in the longer term.

CBT-I is typically delivered over 6 to 8 individual sessions and involves several interconnected components:

Sleep restriction

This is often the most counterintuitive component for people new to CBT-I. Sleep restriction involves temporarily limiting the time spent in bed to roughly match the actual time spent sleeping (not the time lying awake). For example, someone sleeping 5 hours on average but spending 9 hours in bed would initially set a 5-hour sleep window. This builds sleep pressure (the biological drive to sleep), reduces time spent awake in bed, and begins to consolidate sleep. The window is gradually extended as sleep efficiency improves. Sleep restriction sounds punishing but is the most powerful component of CBT-I for breaking the wakefulness-in-bed pattern.

Stimulus control

Stimulus control therapy addresses the learned association between the bed and wakefulness. If you spend long hours lying awake in bed, the bedroom environment becomes associated with arousal and wakefulness rather than sleep. Stimulus control involves: going to bed only when sleepy; getting out of bed if awake for more than 15-20 minutes; using the bed only for sleep (and sex); and keeping a consistent wake time regardless of how well you slept. Over time, the bedroom re-associates with sleepiness and sleep onset.

Cognitive restructuring for sleep beliefs

People with insomnia often hold unhelpful beliefs about sleep that increase arousal and make recovery harder: "I need 8 hours or I cannot function," "Every bad night damages my health," "I will never sleep normally again." Cognitive restructuring examines the evidence for these beliefs, identifies more accurate and less catastrophic interpretations, and reduces the secondary anxiety about sleep that itself maintains insomnia.

Relaxation training

Progressive muscle relaxation, diaphragmatic breathing, and imagery-based relaxation reduce the physiological arousal that maintains wakefulness. These are taught as skills to use in the pre-sleep period and when waking during the night - not as attempts to force sleep, but as practices that reduce the obstacles to sleep.

Sleep hygiene education

Sleep hygiene refers to behavioural and environmental factors that support or undermine sleep: light and temperature in the bedroom, caffeine and alcohol intake, screen exposure before bed, exercise timing. On its own, sleep hygiene education has limited efficacy for established insomnia, but it is a useful component alongside the more active CBT-I techniques.

For anxiety-related insomnia: integrating anxiety treatment

When anxiety is the primary driver of sleep disruption, CBT-I is typically integrated with anxiety-focused psychological work:

• Worry postponement and scheduled worry time: Developing a practice of noting worry content during the day in a designated period, rather than allowing uncontrolled worry at bedtime
• Cognitive restructuring for anxiety: Examining the anxiety content that appears at bedtime - what is the person actually worried about, how realistic are the feared outcomes, what coping resources do they have
• ACT defusion and mindfulness: Building the capacity to observe worry thoughts as mental events rather than facts, reducing their power to maintain arousal
• Intolerance of uncertainty work: For GAD-type anxiety that generates wide-ranging bedtime worry, working specifically with the discomfort of uncertainty

Telehealth for anxiety and sleep: what to expect

A 2021 systematic review by Zachariae and colleagues (Sleep Medicine Reviews) found that digital and internet-delivered CBT-I produces significant improvements across all key sleep outcomes including insomnia severity, sleep onset latency, wake after sleep onset, and sleep quality, with effects comparable to face-to-face CBT-I. Shaker et al. (2023, JMIR Mental Health) confirmed that internet-delivered CBT for anxiety is similarly effective. Telehealth delivery of both CBT-I and anxiety treatment is now well-established.

Practical advantages of telehealth for sleep and anxiety treatment:

• No commute before bedtime: Evening appointments via telehealth mean no driving home after a session, which matters when sleep restriction is part of treatment and session timing may need adjusting
• Sessions from your actual sleep environment: The psychologist can, with your consent, see your actual bedroom setup and help you identify stimulus-control or environment factors directly - rather than working from description alone
• Homework integration: Sleep logs, worry postponement practice, and relaxation exercises all happen in your actual daily and nightly routine - not translated from a clinic to home
• Flexible scheduling: Anxiety and poor sleep often make early-morning appointments difficult; telehealth psychologists typically offer a wider range of times including evenings

What a typical session involves

Early sessions focus on assessment: understanding the history of the sleep problem, the anxiety presentation, sleep patterns (often via a sleep diary kept between sessions), beliefs about sleep, and daytime functioning. The psychologist will explain the CBT-I model and the rationale for each component before starting. Middle sessions implement sleep restriction, stimulus control, and cognitive work. Later sessions consolidate gains, develop a relapse prevention plan, and ensure skills are embedded before finishing.

Most people notice meaningful change in sleep within the first few weeks of implementing sleep restriction and stimulus control, though it often feels harder before it feels easier. The process is active - CBT-I asks more of you than a pill - but the improvements tend to be lasting rather than dependent on continuing a treatment.

How to access a psychologist in Sydney for anxiety and sleep

Step 1: See your GP

Your GP is the right starting point. They can:

• Assess whether there is a medical cause for your sleep disruption (sleep apnoea is common and treatable; thyroid conditions, medication effects, and circadian rhythm disorders can all affect sleep)
• Rule out or address any physical health factors before or alongside psychological treatment
• Issue a Mental Health Treatment Plan (MHTP), which gives you access to up to 10 Medicare-rebated psychology sessions per calendar year
• Provide a referral to a psychologist who works with sleep and anxiety

Tell your GP about both the anxiety and the sleep difficulties. Both can be included in the plan. If your GP does not seem familiar with CBT-I, you can ask specifically whether a referral for CBT-I for insomnia alongside anxiety treatment is appropriate.

Step 2: Find a psychologist with experience in anxiety and sleep

Look for a psychologist who:

• Has experience treating both anxiety disorders and sleep-related presentations, ideally with specific familiarity with CBT-I
• Offers telehealth sessions (standard under Better Access since 2021)
• Is registered with AHPRA (required for Medicare rebates)

The directory of Sydney telehealth psychologists includes practitioners who work with anxiety. When contacting a practitioner, ask whether they have experience with CBT-I for insomnia alongside anxiety treatment.

Step 3: Attend your first appointment

See our guide on what to expect from your first psychology session. For sleep and anxiety presentations, it helps to come prepared with a rough picture of: how long the sleep difficulties have been present, what a typical night looks like (what time you go to bed, how long it takes to fall asleep, how often you wake, what time you wake for the day), and how your anxiety and sleep interact (does anxiety worsen sleep, does poor sleep worsen anxiety, or both).

A note on timing: do not wait until it is unbearable

Many people with anxiety and sleep difficulties wait much longer than they need to before seeking help. Sleep disruption compounds anxiety which compounds sleep disruption - the longer the pattern continues, the more entrenched it becomes. If you have been struggling with sleep and anxiety for months or years, you are not unusual, but you are also not beyond help. CBT-I and psychological treatment for anxiety are effective at all stages, including for long-standing insomnia.

If you are wondering whether your situation is severe enough to warrant help: if it is affecting your daily functioning, your work, your relationships, or your sense of wellbeing, it is sufficient reason to seek support.
