Insomnia — difficulty falling asleep, staying asleep, or waking too early with inability to return to sleep — affects an estimated 10–30% of adults to a clinically significant degree. Occasional poor sleep is universal, but persistent insomnia lasting three or more nights per week for at least three months warrants a structured approach. Effective options exist, and the first steps do not require medication.

Understanding What Drives Insomnia
Insomnia is rarely caused by a single factor. The most widely accepted model identifies three overlapping contributors:
- Predisposing factors: genetic tendency to light sleep, heightened arousal responses, or anxiety traits.
- Precipitating factors: an acute stressor — illness, bereavement, job loss — that disrupts sleep initially.
- Perpetuating factors: the behaviours and thought patterns that maintain insomnia after the original trigger has resolved — lying in bed awake, excessive time in bed, catastrophic thoughts about sleep loss, and irregular sleep schedules.
Sleep Hygiene: The Foundation
Improving sleep hygiene alone rarely cures chronic insomnia but is a necessary starting point:
- Keep a fixed wake time seven days a week — this is the most powerful anchor for the circadian rhythm.
- Reserve the bed for sleep and sex only — avoid working, scrolling, or watching television in bed.
- Keep the bedroom cool (16–19°C), dark, and quiet.
- Avoid caffeine after 2 pm and alcohol within three hours of bedtime — both fragment sleep architecture.
- Limit daytime napping to 20 minutes and avoid napping after 3 pm.
Clinical guidance from NIH[1] stresses matching home care to symptom severity and seeking urgent review when red-flag signs appear.
Cognitive Behavioural Therapy for Insomnia (CBT-I)
CBT-I is the first-line recommended treatment for chronic insomnia, rated above sleeping tablets by international sleep societies. It is a structured programme delivered over four to eight weeks by a therapist or through validated digital applications. Core components include sleep restriction therapy, stimulus control, cognitive restructuring of unhelpful beliefs about sleep, and relaxation training. Multiple meta-analyses show CBT-I produces long-lasting improvement while sleep medications typically only work for as long as they are taken.
Natural and Low-Risk Adjuncts
- Melatonin: effective for circadian rhythm disruption (jet lag, shift work) and for sleep phase problems; less effective for primary insomnia. Low doses (0.5–1 mg taken 60–90 minutes before bed) are as effective as higher doses for most people.
- Relaxation techniques: progressive muscle relaxation, diaphragmatic breathing, and body-scan meditation reduce pre-sleep physiological arousal.
- Magnesium: some evidence for improvement in sleep quality in older adults with low magnesium intake.

When to Consider Medication
Short-term hypnotic medication (Z-drugs, low-dose antihistamines, or melatonin agonists) may be appropriate for acute insomnia during a crisis period, but should not be the primary long-term strategy. Discuss options with a GP, who can also screen for underlying causes such as obstructive sleep apnoea, restless legs syndrome, depression, or thyroid disease — all of which disrupt sleep and require their own targeted treatment.
