Most people who struggle to sleep are told to "try melatonin" or "avoid screens." But the most effective insomnia treatment isn't a pill — it's a structured programme that rewires how your brain relates to sleep.
Answer 5 questions to see whether your sleep difficulty looks like occasional insomnia or chronic insomnia.
Insomnia is defined clinically as difficulty falling asleep, staying asleep, or waking too early — occurring at least 3 nights per week, for at least 3 months, despite adequate opportunity for sleep, and causing daytime impairment. It affects an estimated 10–15% of adults chronically, and up to 30% experience short-term symptoms at any given time.
Insomnia is not simply "not sleeping enough." People with insomnia often lie in bed for long periods but cannot sleep — the problem is not with the amount of time allocated to sleep, but with the brain's ability to transition into and maintain sleep.
Lasts days to weeks, triggered by a specific stressor — a life event, illness, travel, shift change, or new medication. Often resolves on its own when the stressor resolves.
Persists for 3+ months, occurring 3+ nights per week. Often self-perpetuating — the fear of not sleeping becomes its own cause. Requires targeted treatment.
Difficulty falling asleep. Takes 30+ minutes after getting into bed. Often linked to anxiety, rumination, or an irregular sleep schedule.
Falls asleep but wakes frequently during the night or very early in the morning and can't return to sleep. More common in older adults and those with depression.
The most common cause. Cortisol and adrenaline — the stress hormones — are biologically incompatible with sleep onset. The brain interprets stress as danger, keeping it in a state of alert. Sleep anxiety (worrying about not sleeping) is particularly self-reinforcing.
Over time, the bed becomes associated with wakefulness and frustration rather than sleep. The brain learns to become alert when you get into bed — the opposite of what should happen. This is the core mechanism behind chronic insomnia.
Many common medications disrupt sleep: antidepressants (SSRIs, SNRIs), blood pressure medications (beta blockers), corticosteroids, decongestants, and some asthma medications. If sleep problems coincide with a new prescription, discuss alternatives with your doctor.
Undiagnosed sleep apnea causes repeated micro-awakenings that fragment sleep without full waking. Restless leg syndrome causes uncomfortable sensations that prevent sleep onset. Both are significantly underdiagnosed.
Irregular sleep schedules, late caffeine, alcohol (suppresses REM), excessive screen use before bed, and irregular light exposure all disrupt the circadian system and sleep pressure in ways that can cause or worsen insomnia.
Depression, chronic pain, heart conditions, GERD, hyperthyroidism, and many other conditions are associated with insomnia. In these cases, treating the underlying condition often improves sleep.
Cognitive Behavioural Therapy for Insomnia (CBT-I) is the first-line recommended treatment for chronic insomnia from the American College of Physicians, the British Sleep Society, and the European Sleep Research Society — all recommending it above sleeping pills.
A 2015 meta-analysis of 20 trials found CBT-I produced larger and more durable improvements than pharmacological treatment, with no side effects or dependency risk. Effects persist long after treatment ends; sleeping pills lose effectiveness and create dependency.
Temporarily limit time in bed to your actual sleep time (e.g. 5.5 hours). This builds sleep pressure, consolidating fragmented sleep. Counterintuitive and temporarily uncomfortable — but highly effective within 1–2 weeks.
Use bed only for sleep and sex. If unable to sleep after 20 minutes, get up and return only when sleepy. Breaks the conditioned arousal association between bed and wakefulness.
Consistent schedule, light management, temperature optimisation, caffeine cutoff, exercise timing. Necessary but insufficient alone — most insomnia requires all CBT-I components.
Challenging unhelpful beliefs about sleep ("I must get 8 hours or tomorrow is ruined", "I've lost the ability to sleep"). These beliefs increase arousal and perpetuate insomnia. CBT challenges them directly.
Progressive muscle relaxation, breathing exercises, and mindfulness reduce the physiological arousal that prevents sleep onset. Work best in combination with the other components.
One simple change for better sleep: align your alarm with cycle boundaries. Waking mid-cycle worsens sleep anxiety and daytime fatigue.
