The short answer

The commonest sleep problems are insomnia, obstructive sleep apnoea and restless legs, along with the body-clock problems caused by shift work and jet lag. Insomnia is best treated with CBT for insomnia rather than pills. Loud snoring with pauses in breathing, or heavy daytime sleepiness, can mean sleep apnoea, which needs a GP referral and is very treatable.

Many people have more than one. Sleep apnoea can cause broken sleep that looks like insomnia, and anxiety, depression and pain all make sleep worse. If you’re not sure, see when to see a GP.

How common are they?

Very. In a UK study that followed 2,363 adults from five GP practices in Staffordshire, 37% reported insomnia symptoms, and about 15% of those without insomnia developed it within a year, while most people who had it still had it a year later. Obstructive sleep apnoea is less obvious but also common: one global estimate suggests nearly 1 billion adults aged 30 to 69 have at least mild sleep apnoea, many of them undiagnosed.

What treatments work?

  • Insomnia: CBT for insomnia is the first treatment NICE recommends. A review of 20 trials found it helped people fall asleep about 19 minutes faster and spend 26 fewer minutes awake at night. Sleeping pills are only for short-term use.
  • Sleep apnoea: losing weight and cutting alcohol help, and CPAP, a machine that keeps the airway open with gentle air pressure, works well for moderate and severe cases. It’s free on the NHS.
  • Restless legs: treating low iron often helps, and there are medicines for severe cases.
  • Shift work and jet lag: timing light, sleep and naps to shift the body clock.

Common questions

How do I know if I have a sleep disorder?

Signs worth taking seriously are trouble sleeping on most nights for three months or more, someone noticing you stop breathing or gasp in your sleep, falling asleep in the day without meaning to, or an urge to move your legs that keeps you awake. A GP can assess you and refer you to a sleep clinic if needed.

What does a sleep clinic do?

Sleep clinics diagnose and treat sleep disorders. For suspected sleep apnoea you'll usually be given a small monitor to wear at home overnight. For other problems you may have an overnight study in the clinic. You need a GP referral for NHS sleep clinics.
