Recent research shows that insomnia affects as many as 40% of adults and can be chronic in up to 22% of the population 1. This means that a lot of people experience fragmented, poor quality sleep.
Because of how important sleep is to overall health, it’s not surprising that poor sleep can lead to things like:
With symptoms like these, lots of people try to get better sleep via increased alcohol consumption, prescription drugs or over-the-counter remedies 2.
Although these strategies might work in the short term, they aren’t permanent solutions and come with their own problems i.e. side effects and addiction risk.
What would be better is a long-term, non-pharmacological approach, tailored to each individual patient.
One of the most effective non-pharmacological techniques to improve sleep over time is called sleep restriction therapy and is usually offered as part of a CBT for insomnia (CBTi) programme. Let’s have a look at what it’s all about.
Sleep restriction therapy is based on the idea that the time someone with insomnia spends awake in bed leads to the formation of a negative set of beliefs about going to sleep (e.g. that they will never be able to get to sleep, or that their sleep is “broken”) and that having those beliefs makes falling and staying asleep harder.
This is because a sufferer goes to bed dreading the time they’ll spend lying awake once there, which means they:
This “worry pattern” makes it harder to get to sleep, making them more worried, which in turn makes it harder to get to sleep, and so on. Addressing these beliefs can help recovery from insomnia.
By intentionally limiting the time in bed and inducing mild sleep deprivation, two things happen:
This eventually translates to a change in mindset, where going to bed is no longer associated with a battle to fall asleep 4.
Therefore, it’s important to work with a good sleep therapist either in person or over the internet 6, using a service like Sleepstation, so that you get the best outcome possible.
The steps to getting started with sleep restriction therapy usually follow this sequence:
A clinical interview will be conducted to see if sleep restriction therapy can help you.
You will then be asked to complete a sleep diary across a few weeks containing estimations of:
Based on this information, the therapist will set the total time permitted in bed (typically the average time you are actually asleep and no less than 5 hours per night to prevent excess fatigue 2.
The times of the day that are set, for going to and getting out of bed, depend on the type of insomnia that you exhibit:
You then follow the schedule until you and the therapist agree there’s a consistent increase in the time spent asleep versus the total time you’ve spent in bed. At this point, more time in bed will be permitted.
Once out of your bed for the day, you shouldn’t lie down, nap or be in bed at all until the next scheduled bedtime.
Throughout the process, you will be regularly monitored, so that adjustments to the sleep schedule are easily made. Treatment is usually completed within a few months.
Given the fairly drastic changes in sleep habit that sleep restriction therapy demands, it’s likely you’ll find the first few weeks on sleep restriction therapy somewhat difficult.
You may experience daytime sleepiness, reduced alertness, mood disturbance and impaired working or socialising 8. If you are experiencing daytime sleepiness do not drive or operate machinery.
Even though some of these effects may be down to your underlying insomnia more than the treatment 9, we understand that they can be rather discouraging.
Therefore, it’s important to have support available to you across a course of sleep restriction therapy.
That’s why we at Sleepstation provide access to a team of sleep coaches and therapists. Our team can provide perspective and motivation to see you through and help identify ways to make sleep restriction therapy more compatible with your lifestyle.
Unlike a course of sleeping pills, sleep improvements from a course of sleep restriction therapy last for a number of months after treatment, with studies reporting consistent increases in the time in bed spent asleep and fewer awakenings while in bed 13101112.
After the difficult initial period, many people report that their attitudes towards sleep and going to bed have changed because of the long-lasting sleep improvements resulting from sleep restriction therapy 12.
Perhaps unsurprisingly, brain scans of some insomnia sufferers who have undergone sleep restriction therapy show brain activity that is closer to that of good sleepers while in deep sleep 13, suggesting that the longevity of the improved sleep effects may be down to some physiological changes.
Furthermore, patients who have undergone sleep restriction therapy report improved mood, reduced daytime fatigue, fewer sleep worries and napping tendencies compared to when they went untreated 14.
Most importantly sleep restriction therapy can be successfully implemented as part of a wider array of nonpharmacological treatments on a diverse range of people.
So, no matter how bad you think your individual circumstance may be, if you have insomnia, sleep restriction therapy as part of a course of CBTi is very likely to help you.
