Insomnia and Sleep Issues
Insomnia involves persistent difficulty falling asleep, staying asleep, or getting restful sleep, despite having the opportunity to do so. Sleep and mental health are closely and often bidirectionally linked — poor sleep can worsen anxiety, depression, and stress, while those conditions can also disrupt sleep, creating a cycle that’s genuinely difficult to break without support.
This page covers what insomnia tends to look like, what contributes to it, and how psychological support — particularly a structured, evidence-based approach called CBT-I — can help.
Recognising it
What does insomnia look like?
Night-time
- Difficulty falling asleep, even when tired
- Waking frequently during the night, or waking too early and being unable to fall back asleep
- Lying awake worrying about not being able to sleep
Daytime & knock-on effects
- Daytime fatigue, difficulty concentrating, or irritability from poor sleep
- Anxiety or dread about bedtime, anticipating another poor night’s sleep
- Relying on strategies like screens, alcohol, or extended time in bed that may unintentionally be maintaining the problem
Insomnia is generally considered clinically significant when it occurs at least three nights a week for three months or more and causes distress or affects daytime functioning, though shorter-term sleep difficulty is also worth addressing rather than waiting for it to reach that threshold.
Understanding why
What contributes to insomnia?
There's rarely a single cause — it tends to develop from a combination of factors.
- Psychological factors
- Anxiety, depression, and stress are among the most common contributors to insomnia, and insomnia can also occur on its own.
- Learned patterns
- Over time, the bed and bedtime can become associated with wakefulness, frustration, or worry rather than sleep, which reinforces the problem.
- Habits & routine
- Irregular sleep schedules, screen use before bed, or daytime napping can all contribute.
- Life stress or major transitions
- Insomnia often begins during a stressful period and can persist as a learned pattern even after the original stressor resolves.
- Other health conditions
- Some medical conditions and medications can affect sleep, which is worth discussing with a GP.
Insomnia frequently persists not just because of the original cause, but because of the anxiety and habits that build up around trying to sleep — which is exactly what structured psychological treatment addresses.
Getting better
How is insomnia treated?
Cognitive behavioural therapy for insomnia (CBT-I)
A structured, short-term therapy considered the first-line treatment for chronic insomnia, more effective for long-term improvement than medication alone.
Sleep restriction & stimulus control techniques
Specific behavioural strategies used within CBT-I to rebuild a strong association between bed and sleep.
Addressing anxiety about sleep
Much of CBT-I focuses on reducing the worry and frustration that build up around not sleeping, which often perpetuates the problem.
Treating underlying conditions
Where insomnia is connected to anxiety, depression, or another condition, addressing that condition is often an important part of resolving sleep difficulty too.
CBT-I has strong evidence for effectiveness and is generally recommended ahead of long-term reliance on sleep medication, which a GP can discuss with you if relevant to your situation.
Next step
When should I see a psychologist about insomnia?
You don't need to wait until symptoms feel unmanageable.
- Difficulty sleeping that’s persisted for more than a few weeks
- Sleep difficulty significantly affecting your mood, concentration, or daily functioning
- Anxiety or dread specifically about sleep or bedtime
- Insomnia alongside symptoms of anxiety, depression, or stress
A GP can help you access a Mental Health Care Plan under Medicare's Better Access initiative, which provides rebates for a set number of psychology sessions per year.

Common questions
Frequently asked questions
Is insomnia a mental illness?
Insomnia is a recognised sleep disorder, and it can occur on its own or alongside another mental health condition. Either way, it’s a legitimate concern worth addressing directly, not something to just push through.
Do I need sleep medication to fix insomnia?
Not necessarily. CBT-I is generally recommended as a first-line treatment and has strong evidence for producing longer-lasting improvement than medication alone, though a GP can discuss whether medication is appropriate for your specific situation, particularly in the short term.
How long does CBT-I take to work?
CBT-I is typically a structured, short-term therapy, often delivered over a number of weeks, with many people noticing improvement within that timeframe, though this varies by individual.
Can poor sleep cause anxiety and depression, or is it the other way around?
Both directions are well established — poor sleep can worsen anxiety and depression, and those conditions can also disrupt sleep. This is part of why addressing both together often produces the best results.
Do I need a GP referral to see a psychologist about insomnia?
No — you can see a psychologist directly. A GP referral is only required if you want to access a Medicare rebate through a Mental Health Care Plan, though seeing a GP first can be useful to rule out medical contributors to sleep difficulty.
