Bad sleep is a waking nightmare for millions, but around 90% of those people could improve their sleep quality in just one week, according to an expert.
Jason Ellis, a professor of sleep science at Northumbria University, has devised a cognitive behavioural therapy (CBT) course containing seven steps – one per day – to tackle sleep problems, all outlined in his new book, The One-Week Insomnia Cure.
Ellis said about a third of the population suffer from insomnia every year, and it persists for about 10-15% of them. But what causes insomnia and why it persists aren’t the same thing.
After a stressful experience, for example, someone may sleep badly for up to two weeks. But if it continues after that, said Ellis, it’s largely because people develop habits they think are helpful to get them to sleep, or they worry about not sleeping. It’s these things that fuel insomnia.
The 7-day cure
Ellis said people can tackle insomnia themselves, rather than seeking medical help or trying over-the-counter remedies.
The first, and integral, step is completing a sleep diary every morning, noting what time you went to bed, how long it took to fall asleep, etc.
Armed with your sleep diary, the basic course steps are…
Day 1: Sleep rescheduling
A personal sleep schedule is created by using your sleep diary to calculate your total sleep time (TST) average over a week, by estimating time in bed minus time awake in bed. Divided by seven days, this average becomes your prescribed time in bed (PTIB), which should never be less than five hours.
From your PTIB, calculate your bedtime and wake time, and if this new bedtime is later than normal, you can do anything during the pre-bedtime period, except work, exercise, eat, look at pornography, use a device which emits blue light, or nap, as these aren’t conducive to immediate sleep.
Day 2: Stimulus control
This seeks to break the association between the bedtime routine, the bed, and not being able to sleep. The rules are that the bedroom should only be used for sleep and sex, there should be no napping elsewhere, and if you’re in bed and can’t sleep, get up and leave the bedroom. Ellis suggested going to a warm place away from the bedroom for about 30-45 minutes, but don’t lie down or fall asleep during this time.
Day 3: Cognitive control
Determine a cut-off time when you stop all your daytime activities, like work. Then, at least two hours before bedtime, write lists about what you’ve achieved during the day, what you hope to achieve tomorrow and how you feel about it, followed by writing down your worries, and what you can do about them. Leave the notebook by the bed, in case you think of anything else during the night.
Day 4: Cognitive distraction
These are the practical steps to slow down your racing mind, by filling it with other, all-consuming, thoughts – alphabetical, numerical or visual. Examples are counting backwards from 1,000 in sevens, or thinking of, say, a city beginning with A, and then thinking of a city beginning with whatever letter your first city ended with, etc.
