Poor sleep
Symptoms & signs
Short answer
Sleeping badly? First work out what is happening. Too little time in bed calls for more sleep opportunity; trouble sleeping despite enough time calls for a different approach. Try a regular wake time and a calming bedtime routine. If sleeplessness persists and affects your day, ask about cognitive behavioural therapy for insomnia (CBT-I): it is recommended for adults with chronic insomnia, whereas sleep-hygiene tips alone are not enough. Report breathing pauses or severe daytime sleepiness; do not drive sleepy. [1][2]
Trouble falling asleep, staying asleep or getting enough sleep. What helps depends on the pattern; chronic insomnia has a specific treatment.

Which problem needs which next step?
- Not enough time to sleep? Make more room for sleep where possible and keep a steady wake time. [1]
- Cannot sleep despite having time? Notice how often you lie awake, wake during the night or wake too early. If this continues and affects the day, discuss insomnia treatment. [1][2]
- Snoring with breathing pauses or dozing off in the day? Seek assessment for a possible sleep disorder rather than trying a sedative. Do not drive when sleepy. [1]
One bad night is not chronic insomnia. The NHS calls recurring sleep problems lasting under three months short-term and those lasting three months or more long-term insomnia. [1]
Common contributors
Ask whether stress, anxiety, depression, noise, temperature, caffeine, nicotine or alcohol disrupt sleep. Shift work, jet lag, pain, menopause, medicines and restless legs can also play a role. Loud snoring and breathing pauses suggest sleep apnoea and deserve assessment, not just a quieter bedroom. Poor sleep may contribute to fatigue, but fatigue can also have other causes. A diary of bedtime, waking, stimulants and daytime effects can make a consultation more useful. [1]
Practical routine
Try a consistent wake time, go to bed when sleepy and make room for a calming pre-bed routine. A dark, quiet, comfortable bedroom and avoiding caffeine, nicotine and alcohol near bedtime may help. Regular daytime activity can support sleep, but do not drive when sleepy. These steps reduce avoidable barriers; they are not a standalone cure for chronic insomnia. Avoid purchasing a sleep supplement based only on a claim that it 'supports sleep.' [1] [2]
If sleep stays difficult: ask about CBT-I
CBT-I is a structured treatment that tackles habits and thoughts that keep insomnia going. The 2021 AASM clinical guideline strongly recommends a combination of CBT-I approaches for adults with chronic insomnia and advises against sleep hygiene alone as treatment. A trained provider can adapt the bed-and-sleep association and sleep schedule to your health and safety; do not attempt sleep restriction from a generic article. Sleeping pills can cause dependence or other side effects and are generally for short-term use. [2][1]
When to get help
Seek clinical help when changing habits has not helped, you have struggled for months or it is hard to cope in daily life. Report breathing pauses, gasping, severe daytime sleepiness and safety problems such as nearly falling asleep while driving. Sleep health involves timing, regularity and quality as well as duration: the separate sleep quality page explains those dimensions. Do not treat an untreated breathing disorder with an over-the-counter sedative. [1] [3]
Frequently asked questions
How much sleep do adults need?
The NHS gives an average of seven to nine hours for adults, but individual needs vary. The ability to function by day matters too. [1]
Is sleep quality only duration?
No. AASM also names quality, timing, regularity and absence of untreated sleep disorders. [3]
What is CBT-I?
A structured approach to the thoughts and habits keeping insomnia going. The AASM strongly recommends multicomponent CBT-I for adults with chronic insomnia; bedtime tips alone are not an equivalent treatment. [2]
When seek help?
When habits do not help, problems last months or impair daily life. Breathing pauses and severe daytime sleepiness are reasons to discuss assessment. [1]
Does one bad night mean insomnia?
No. Occasional restless nights differ from recurring difficulty and impaired functioning; long-term insomnia lasts at least three months. [1]
Research and sourcesEvidence overview, methods and complete source list
Research context
First distinguish too little sleep opportunity from lying awake despite enough time. A regular wake time helps routine; CBT-I is recommended for adults with chronic insomnia.
Finding: The AASM guideline strongly recommends multicomponent CBT-I for adults with chronic insomnia; sleep hygiene alone is not an equivalent treatment. One bad night does not automatically call for CBT-I.
CBT-I for chronic insomnia
Evidence: AASM clinical practice guideline: recommendations/abstract read; full article text unavailable.
Studied population: Adults with chronic insomnia, not everyone with an occasional bad night.
Form or context: Clinician-guided multicomponent cognitive behavioural therapy, not a supplement.
Uncertainty: Recommendation is not an individual effect size; other sleep problems need their own assessment.
Safety: Breathing pauses or severe daytime sleepiness deserve assessment; do not drive sleepy. Do not attempt sleep restriction or use sedatives on your own for a possible sleep disorder.
