What is Insomnia?
Insomnia involves persistent difficulty falling asleep, staying asleep, or waking too early, along with daytime effects like tiredness, poor concentration, or low mood. Occasional poor sleep is common and usually not a concern, but insomnia lasting weeks or longer can significantly affect quality of life.
It can be triggered or worsened by stress, anxiety, poor sleep habits, certain medications, or underlying health conditions. Effective treatments exist, and cognitive behavioural therapy for insomnia (CBT-I) is considered one of the most effective long-term approaches.
02 · Understand
Clinical context
CBT-I is often more effective than sleeping tablets long-term
Cognitive behavioural therapy for insomnia (CBT-I) addresses the habits and thoughts that maintain poor sleep, and has strong evidence of providing more lasting improvement than medication alone.

Practical steps
Avoid Relying Long-Term on Sleeping Tablets
Sleeping tablets can be helpful for short-term use but aren't generally recommended long-term, as they don't address the underlying causes of insomnia and can lead to dependence — speak to a GP about more sustainable options.
- 1Keep a consistent sleep schedule.Going to bed and waking at the same time each day, even on weekends, helps regulate your body clock.
- 2Limit screens before bed.Bright screens can interfere with the body's natural sleep signals.
- 3Avoid caffeine and alcohol close to bedtime.Both can disrupt the ability to fall or stay asleep.
- 4Only go to bed when sleepy.Lying awake in bed for long periods can train the brain to associate bed with wakefulness — getting up and doing something calm until sleepy again can help.
- 5Ask about CBT-I.This structured therapy addresses the habits and thoughts underlying insomnia and has strong long-term evidence of effectiveness.
