Need to know
Most of us struggle after a night of poor sleep: we feel groggy, tired, irritable – there’s a general sense that we’re not firing on all cylinders, or like we’re going through our day in a ‘fog’. Insomnia sufferers know these symptoms all too well.
Individuals who experience insomnia often describe it as a debilitating, distressing, deeply frustrating condition that affects all aspects of their life. The negative impact of just one night of poor sleep can weigh heavily on us, so for those who are consistently sleeping poorly it can feel like torture. Sleeping should be easy, right? Why can’t I just close my eyes and fall asleep like everyone else? – a question I’ve heard many times in the sleep clinic. Insomnia can be such a cruel condition. The desperate desire for sleep and the increasing frustration that comes with being unable to sleep actually makes it even harder to get to sleep. Breaking this vicious cycle is one of the keys to overcoming insomnia.
Securing good sleep is essential for physical and mental health. When sleep is healthy, it helps the body recharge, fuels its natural ability to heal, and plays a vital role in helping the brain process the day’s events. Most adults need between seven and nine hours of sleep to feel sufficiently rested, though the exact duration needed varies from person to person. People with insomnia often report not getting sufficient sleep; some report just five or six hours. Others get more, but it is typical for people with insomnia to have highly fragmented sleep – in other words, they don’t sleep solidly and have long periods of wakefulness in their sleep.
Broadly speaking, insomnia involves persistent difficulty with getting to sleep and/or staying asleep, at least three nights per week. For those with chronic (vs short-term) insomnia, this goes on for a period of at least three months. These difficulties are accompanied by daytime symptoms such as fatigue, memory or concentration problems, or irritability. There also has to be some degree of dissatisfaction or distress about one’s sleep. Importantly, for the problem to be classed as insomnia, these issues have to be occurring despite adequate opportunity for sleep (so the sleep problems are not caused by factors such as shift patterns, late-night partying or noisy neighbours). And, the symptoms aren’t better explained by other conditions that can lead to poor sleep, such as circadian rhythm disorders or sleep apnoea.
Insomnia can have a serious impact on a person’s quality of life and day-to-day functioning. It can affect performance at work, relationships, and motivation to exercise and keep a healthy diet. People with insomnia often stop doing the things they enjoy as they no longer have the energy or drive to do them. As a result, they can often feel unhappy, powerless and trapped.
Insomnia is common, but treatable
It’s estimated that around one-third of the general population experiences one or more insomnia symptoms. By some estimates, approximately 10 per cent of people meet criteria for chronic insomnia, making it one of the most prevalent medical conditions. Despite how common it is, accessing evidence-based treatment for insomnia remains a challenge for a number of reasons, so it goes untreated in too many people.
Insomnia is still imperfectly understood by many health professionals – research has found that, on average, medical students receive only 2.5 hours of sleep education – and its signs are often missed or minimised. Furthermore, relatively few people actually seek out support for their sleep problems. It can be hard to know where to turn. Sleep as a specialist field is unregulated, meaning anyone can claim to be a ‘sleep expert’, even if they don’t have any clinical training. People with insomnia are often desperate for a solution, which makes them more vulnerable to unfounded promises and quick-fix ‘sleep solutions’.
In my experience as a clinical psychologist working with insomnia clients, by the time someone has contacted me, they’ve often already tried various supplements, remedies and treatments from an eclectic range of unqualified individuals. They might have also seen their GP and been prescribed sleeping medication. While sleeping pills can provide some short-term relief, they don’t deal with the underlying cause of the insomnia and there’s a risk of dependency, so GPs tend to prescribe them only for a brief period of time. Insomnia sufferers often end up feeling pessimistic about their chances of recovery and sceptical about any further sleep advice.
Thankfully, there are highly effective treatments for insomnia that are supported by solid scientific evidence. Cognitive behavioural therapy for insomnia (CBT-I) is considered the ‘gold standard’ treatment for insomnia by the leading authorities on sleep disorders. CBT-I is a type of psychological therapy that focuses on the role that behaviours and thoughts have in perpetuating sleep problems.
Insomnia is often the result of a period of stress or changes in routine – due to things such as illness, having a baby, changing jobs, relationship issues or bereavement – that causes a disruption in sleep. This in turn can affect how we think about sleep, and so we start to make changes in our sleep behaviours in an attempt to solve the sleep issue: loading up on caffeine, going to bed earlier, consuming alcohol, taking sleep supplements, sleeping on the sofa, etc. Over time, these changes can actually make matters worse. In CBT, we call them ‘maintaining factors’ as they fuel continued sleep problems. By the time someone is seeking help for their insomnia symptoms, the stressful life event has usually long since resolved, yet the sleep problems remain.
CBT-I is a very practical therapy, with the therapist helping the individual to identify, understand and then break the cycles that contribute to insomnia. This is achieved by learning some basic sleep science, making changes to your sleep schedule and habits, challenging common ‘sleep myths’ and other unhelpful beliefs about sleep, learning relaxation strategies, and following good sleep hygiene principles. I tell my insomnia clients that it’s helpful to think about CBT-I as a form of training rather than a therapy, as it requires a lot of self-discipline and hard work; but, the more you put into it, the more you will get out.
After completing treatment, my insomnia clients often say things such as: ‘I feel like the old me again’ and ‘I have my life back’. They have told me that their thinking is sharper and their memory and attention have improved, so they’re performing better at work; that they no longer feel irritable all the time and they’re getting on better with the people in their life. Clients have said that their life looks and feels different, like someone has switched on a light.
If you think you are experiencing symptoms of insomnia, you might benefit from working with a clinician directly. But if you’d like to start by making some changes on your own, this Guide presents a number of strategies, based on CBT-I principles, that you can try at home. Following these steps can help alleviate your insomnia symptoms and set you on the right path to start sleeping well again.
