Sleep Problems and How to Cure Them

Sleep Problems and How to Solve Them | Why you're not sleeping — and what actually fixes it

Around a third of adults in the UK report regular sleep problems. Most of them have tried the basics — cutting caffeine, avoiding screens, keeping a consistent bedtime — and found that it helps a little, or not at all. That's because the standard advice addresses surface habits, not underlying mechanisms. Persistent sleep problems usually have a specific cause. The fix depends on identifying which one.

This page covers the four most common sleep problems in adults over 50, what the evidence actually says about treating each of them, and where self-help ends and clinical investigation should begin.

Insomnia: the most common and most treatable

Insomnia affects roughly 10–15% of adults chronically — meaning difficulty falling or staying asleep at least three nights a week for three months or more. It's more common in women, increases with age, and is frequently linked to anxiety, low mood, or a period of acute stress that has outlasted its original cause.

The critical thing to understand about chronic insomnia is that it becomes self-perpetuating. A run of poor nights creates anxiety about sleep. That anxiety activates the arousal system, which makes sleep harder. The original trigger may be long gone, but the pattern of lying awake, clock-watching, and dreading bedtime has become its own problem. This is why sleeping tablets — which address the symptom — have worse long-term outcomes than CBT-I, which addresses the pattern.

Cognitive Behavioural Therapy for Insomnia is the first-line clinical treatment, rated above medication by UK, US, and European sleep medicine guidelines. It works through a combination of sleep restriction, stimulus control, and cognitive restructuring. Sleep restriction sounds counterintuitive — you temporarily limit time in bed to consolidate sleep and rebuild the drive to sleep. Stimulus control retrains the brain to associate bed with sleep rather than wakefulness. Together, around 80% of people who complete a full course see meaningful improvement, and the results are durable in a way that medication is not. Sleepio delivers CBT-I digitally and is available free via the NHS.

Sleep Problems

Identify the Problem. Use the Right Fix.

Most sleep problems have specific causes — and specific solutions. Using the wrong fix wastes months. This guide maps the five most common problems to the interventions with the best evidence behind them.

Problem → Best Evidence Fix

Insomnia — can't fall asleep, or wake and can't return to sleep

Most common cause: learned arousal. The bedroom becomes associated with wakefulness and anxiety rather than sleep.

What works

✓ CBT-I (Cognitive Behavioural Therapy for Insomnia) — first-line clinical recommendation, ranked above sleeping pills. Available free via Sleepio on the NHS. ✓ Sleep restriction therapy — temporarily compressing time in bed to rebuild sleep pressure. Counterintuitive but highly effective. ✓ Stimulus control — using the bed only for sleep. If you can't sleep after 20 minutes, get up.

Sleep apnoea — breathing stops repeatedly during sleep

Often undiagnosed. Signs: loud snoring, waking unrefreshed, daytime sleepiness, morning headaches, partner reports of breathing pauses.

What works

✓ Get tested first — a home sleep study can now be done without a hospital visit. Don't guess. ✓ CPAP — continuous positive airway pressure. Highly effective when used consistently. Takes 2–4 weeks to adapt to. ✓ Weight loss significantly reduces severity in overweight individuals. Positional therapy (not sleeping on your back) helps mild cases.

Poor sleep quality — in bed long enough but waking unrefreshed

Fragmented, light sleep with insufficient deep (slow-wave) and REM stages. Often caused by alcohol, temperature, stress, or undiagnosed apnoea.

What works

✓ Cool the room to 17–19°C — core temperature must drop to enter deep sleep. This single change has outsized impact. ✓ Cut alcohol — even moderate drinking suppresses REM by ~24% and causes waking after midnight. ✓ Rule out apnoea — fragmented sleep is the most common symptom. Don't assume it's just stress.

Restless legs — urge to move the legs at rest, worse at night

Affects around 5–10% of adults. Often dismissed or misdiagnosed. Can be primary (genetic) or secondary — driven by iron deficiency, kidney disease, or certain medications.

What works

✓ Check ferritin levels — iron deficiency is a common and correctable cause. Target ferritin above 75 µg/L, not just within normal range. ✓ Avoid triggers — caffeine, alcohol, and antihistamines (including many OTC sleep aids) significantly worsen symptoms. ✓ See a GP if symptoms are frequent — dopamine-related medications are highly effective for moderate to severe cases.

Circadian disruption — can't sleep at a normal time, or shifts keep changing

Includes delayed sleep phase (night owls who can't fall asleep before 1–2am), shift work disorder, and social jet lag from irregular schedules.

What works

✓ Anchor the wake time — consistent morning rising is more powerful than a consistent bedtime for resetting the clock. ✓ Morning light immediately on waking — 10–15 minutes outside, every day. The most direct reset signal the clock receives. ✓ Low-dose melatonin (0.5–1mg) taken 5–6 hours before desired sleep onset can shift the clock earlier for delayed sleep phase. Not as a sedative — as a timing signal.

Three Common Mistakes

✗ OTC sleep aids — most contain antihistamines that sedate rather than produce natural sleep architecture, and worsen restless legs. ✗ High-dose melatonin — the 5–10mg doses sold in most shops are 5–20× higher than effective. More is not better; it disrupts the signal. ✗ Lying in hoping to sleep — prolonged wakefulness in bed strengthens the association between bed and arousal. Get up, do something calm, return when sleepy.

Sleep apnoea: the most underdiagnosed

Obstructive sleep apnoea affects an estimated one in four men over 50 and a significant proportion of post-menopausal women, yet the majority of cases go undiagnosed. The reason is simple: it happens while you're asleep. You don't know your airway is partially collapsing dozens of times each hour. You just know you feel exhausted despite spending eight hours in bed.

The consequences are serious. Untreated sleep apnoea significantly raises the risk of hypertension, cardiovascular disease, type 2 diabetes, and cognitive decline. It also fragments sleep so severely that deep and REM sleep are chronically suppressed, which accelerates biological ageing independently of the cardiovascular effects.

The classic signs — loud snoring, witnessed breathing pauses, morning headaches, waking unrefreshed — are worth acting on. But many people with apnoea don't snore loudly, particularly women, whose presentation tends to be more subtle. Unexplained fatigue, frequent night waking, and difficulty concentrating are enough to justify testing. A home sleep test can be arranged through your GP or privately for around £150. CPAP therapy, when used consistently, is one of the most effective interventions in all of sleep medicine — it eliminates the airway obstruction, restores normal sleep architecture, and produces rapid improvements in energy, mood, and cardiovascular markers.

The 3am problem: early waking and what drives it

Waking in the early hours and being unable to return to sleep is one of the most common complaints in adults over 50, and it's distinct from insomnia. It's rarely about sleep hygiene. The most common drivers are cortisol dysregulation, alcohol, and low mood.

Cortisol follows a strong daily rhythm, rising sharply in the early morning to prepare the body for waking. In people under chronic stress, or with disrupted circadian rhythms, this rise can come too early — pulling them out of sleep at 3 or 4am with a sense of alertness or anxiety that makes returning to sleep impossible. The fix is upstream: reducing chronic stress load, anchoring the circadian rhythm with consistent wake times and morning light, and addressing the anxiety that drives the cortisol pattern.

Alcohol is the other major cause, and frequently overlooked. Two units in the evening suppresses REM sleep in the second half of the night and produces a rebound arousal as the sedating effect wears off. The 3am wake is textbook alcohol disruption. If this is a regular pattern, removing alcohol for two weeks is both a diagnostic test and a treatment.

Depression consistently presents with early morning waking — waking one to two hours earlier than intended, with a low or anxious mood that is worst in the morning and gradually lifts through the day. This pattern warrants a conversation with a GP rather than more sleep optimisation.

Restless legs and periodic limb movement

Restless legs syndrome — an uncomfortable urge to move the legs in the evening and at rest, relieved by movement — affects around 5–10% of adults and becomes more common with age. It's distinct from cramping or general leg discomfort. The sensation is typically described as crawling, pulling, or an irresistible need to move, appearing reliably in the evening and disrupting both sleep onset and sleep quality.

Iron deficiency is a significant contributor, even in people whose blood counts appear normal — ferritin levels below 75 mcg/L have been associated with worsening symptoms, and iron supplementation can produce meaningful improvement. Magnesium deficiency is also implicated. Before pursuing pharmacological treatment, it's worth checking ferritin and magnesium levels and addressing any deficiency.

Certain medications can trigger or worsen restless legs, including some antidepressants (particularly SSRIs and tricyclics), antihistamines, and antinausea drugs. If symptoms appeared or worsened after starting a new medication, that's worth discussing with your prescriber.

'Most persistent sleep problems have a specific cause — insomnia, apnoea, early waking, restless legs. The self-help advice is largely the same for all of them, which is why it often doesn't work. Identifying which problem you actually have is the most important step.'

When to stop self-optimising and see someone

Sleep hygiene and habit changes are a reasonable first step for mild, recent sleep problems. They are not sufficient for persistent problems with a structural cause. The threshold for seeking clinical input is lower than most people assume.

If you've had sleep problems for more than three months, see your GP. If you're exhausted despite adequate time in bed and snore or share a bed with someone who has noticed breathing pauses, request a sleep apnoea test. If early morning waking is accompanied by persistent low mood, don't treat it as a sleep problem alone. If you're using alcohol to fall asleep regularly, that pattern warrants attention beyond sleep.

The NHS pathway for sleep problems is more accessible than most people realise. CBT-I via Sleepio is available on prescription. Sleep apnoea testing can be done at home. The barrier is usually the assumption that poor sleep is just something to be managed rather than something to be fixed.
