Insomnia
Part 4: CBT-insomnia
BACKGROUND:
🔎Cognitive-Behavioural Therapy for Insomnia (CBT-I) is a structured, short-term psychosocial intervention designed to help people with chronic insomnia reduce sleep difficulties by changing the thoughts, behaviours, and habits that keep insomnia going.
COGNITIVE RESTRUCTURING:
🧠 Cognitive restructuring begins to break this cycle by identifying, challenging, and altering the thoughts and beliefs that contribute to insomnia. Common thoughts and beliefs that may be addressed during treatment include anxiety about past experiences of insomnia, unrealistic expectations of sleep time and quality, and worry about daytime fatigue or other consequences of missed sleep.
STIMULUS CONTROL:
🛌 Many people with insomnia begin to dread their bedroom, associating it with wakefulness and frustration. They may also associate their bedroom with habits that make sleeping more difficult, like eating, watching TV, or using a cell phone or computer. Stimulus control attempts to change these associations, reclaiming the bedroom as a place for restful sleep.
SLEEP RESTRICTION:
🕰️ lPeople with insomnia often spend excessive time in bed awake, which weakens the association between the bed and sleep. Sleep restriction therapy addresses this by temporarily limiting time spent in bed to increase homeostatic sleep drive and consolidate sleep, even though this may initially increase daytime sleepiness. Treatment begins with estimating average total sleep time using a sleep diary. Time in bed is then prescribed to closely match this average sleep duration, typically with a minimum buffer of approximately 30 minutes.
❌NOT recommended for people with certain medical conditions that can be made worse by losing sleep, such as bipolar disorder and seizures.
RELAXATION TRAINING
🧘 Breathing exercises: deep, slow breaths to reduce heart rate and promote relaxation
Progressive muscle relaxation (PMR): tensing and relaxing muscles with guided imagery
Autogenic training: body ‘scanning’ to focus on specific sensations (eg: warmth, heaviness etc)
Biofeedback, hypnosis or meditation etc.
SLEEP HYGIENE:
😴 Maintain a sleep schedule: Having a regular, predictable sleep schedule can help your body maintain a rhythm and make it easier to fall asleep. This includes weekends too, which are a common time to forget about the importance of sleep.
❌Don’t lie awake in bed: If you can’t sleep, get out of bed and find something relaxing to do until you feel tired again.
📝Create a nightly routine: Give yourself enough time to get ready for bed. Turn off your electronics early and find some relaxing activities that help you wind down before sleep.
🚴♀️ Consider daytime activities: What you do during the day really counts. Even a small amount of exercise can help you sleep better. 🗣️Also try to avoid eating, alcohol, and caffeine too close to bedtime.
CONSIDERATIONS:
👨⚕️In order for CBT-I to be effective, it’s important to be open to confronting unhelpful thoughts and behaviours. While the risks of treatment are likely to be mild, it may be uncomfortable at times. Talking about painful experiences, thoughts, and feelings can be challenging and may cause temporary stress and discomfort.
