Problems Sleeping
Up at 3 am again, watching the hours tick away? Insomnia is more common than most people realise, and what works to treat it has changed considerably in the last few years. Here's the latest, properly sourced.

Up to 40% of UK adults have difficulties with their sleep at any given time, according to The Sleep Charity. For some, it’s a few rough weeks. For others, it’s months or years of waking at 3 am and staring at the ceiling, knowing the alarm will go off in three hours.
Our 2026 UK Sleep Survey of 2,000 UK adults paints a similar picture. Eight in ten of us have at least one bad night every week. Nearly one in five (19%) report a disturbed, broken or bad night every single night. On a typical bad night, the average UK adult spends 1 hour and 27 minutes awake or trying to drift off.
This article walks through what insomnia actually is, what causes it, and what current clinical guidance says about treating it. It is not a substitute for medical advice. If your sleep has been a problem for more than 3 months or is affecting your daily life, please speak to your GP.
Insomnia is when you regularly have problems sleeping. That usually means difficulty falling asleep, waking up in the night, lying awake, waking too early, or not feeling refreshed when you do wake up.
Doctors split insomnia into two types based on how long it has been going on:
The distinction matters. Short-term insomnia often eases off on its own once the trigger fades. Long-term insomnia is harder to shift, because the patterns and behaviours that develop alongside it can keep it going long after the original cause has gone. That’s usually when GP or specialist support comes in.
You may have insomnia if you regularly:
Most adults need 7 to 9 hours of sleep a night. If you’re consistently getting less and feeling the effects, that’s worth paying attention to.
Sleep researchers often describe insomnia using the 3P model, developed by sleep psychologist Arthur Spielman. It splits the causes into three layers:
When we asked 2,000 UK adults what was keeping them awake in our 2026 Sleep Survey, the most common answers were:
Other common contributors include noise, an uncomfortable bed, room temperature, alcohol, caffeine, nicotine, jet lag and shift work.
Not all sleep problems are insomnia. A few other conditions can look similar but need different treatment, so it’s worth knowing the warning signs:
If your sleep problems come with any of these other signs, mention them to your GP. The right diagnosis changes the treatment.
Clinical guidance on long-term insomnia has shifted considerably in the last few years. The current first-line treatment is cognitive behavioural therapy for insomnia, known as CBT-i.
That’s a meaningful change. For decades, a common default response to persistent insomnia was a short course of sleeping pills. Evidence now suggests that CBT-i works better long-term, doesn’t cause dependence, and continues to help after treatment ends.
The treatment ladder, in current NICE guidance, looks roughly like this:
CBT-i is a structured talking therapy designed specifically for chronic insomnia. It usually runs over six to eight sessions with a trained therapist, either face-to-face or through a digital programme. The therapy works on the habits, thoughts and behaviours that keep insomnia going.
Many people with long-term insomnia see meaningful improvement after CBT-i, and the benefits often outlast the treatment itself.
Access to face-to-face CBT-i varies widely by region, and waits can run to three months or more. A few digital options have helped close the gap:
Kathryn Pinkham, founder of The Insomnia Clinic and one of the UK’s leading specialists in the area, has summed up the evidence simply: studies show that on average around 70% of people with even very long-term poor sleep get lasting benefit from CBT-i.
For short-term insomnia, the recommended habits align closely with what CBT-i includes:
Do:
Don’t:
The last one is the one most people get wrong. Sleeping in after a rough night feels like a reward, but it tends to make the next night worse by reducing the body’s natural sleep pressure.
An uncomfortable bed is one of the most common causes of insomnia. Almost one in four UK adults (23%) blame physical comfort issues for their bad nights, and 24% blame being too hot, according to our 2026 Sleep Survey.
