When to see a doctor about your sleep

Book a GP appointment if any of these apply

Breathing-related signs

• You snore loudly, or your partner has noticed you stop breathing or gasp during sleep.
• You wake up with a dry mouth or sore throat most mornings.
• You feel tired during the day despite 7+ hours in bed.
• You wake with morning headaches.

These suggest obstructive sleep apnoea — common, underdiagnosed, and very treatable once identified.

Chronic insomnia

• Difficulty falling, staying, or returning to sleep three or more nights a week, for three months or longer.
• Daytime impact (fatigue, mood, cognitive impairment).
• You've tried good sleep hygiene without sustained improvement.

This meets the clinical threshold for insomnia. CBT-I is first-line treatment per every major guideline — ask your GP about referral or an app-based programme like Sleepio.

Mental health overlap

• Sleep problems alongside persistent low mood or anhedonia.
• Sleep problems alongside significant anxiety or panic attacks.
• Any thoughts of self-harm — see a doctor urgently.

Sleep and mental health are deeply intertwined. Treating either improves the other; ignoring either usually worsens both.

Excessive daytime sleepiness

• Falling asleep involuntarily during the day.
• Sudden muscle weakness with strong emotion (cataplexy-like episodes).
• Sleep paralysis or vivid dream-like experiences while falling asleep or waking.
• Regularly needing 9+ hours and still feeling unrefreshed.

These can indicate narcolepsy, idiopathic hypersomnia, or underlying medical conditions (hypothyroidism, anaemia, depression).

Disrupted sleep with physical symptoms

• Uncomfortable sensations in your legs at night, or compulsion to move them.
• Acting out dreams (kicking, shouting, hitting bed partner).
• Frequent night sweats not explained by room temperature.
• Waking with chest pain, gasping, or palpitations.
• Frequent urination at night (more than once or twice).

Children and adolescents

• Persistent snoring in a child (not normal).
• Significant daytime sleepiness affecting school or behaviour.
• Sleepwalking or night terrors that cause injury or persistent distress.

Which specialist sees what

• GP / family doctor— the right starting point for almost everything. They'll refer onward.
• Sleep clinic / respiratory consultant — for suspected sleep apnoea. Most areas have NHS referral pathways for home sleep studies.
• CBT-I therapist (clinical psychologist or accredited practitioner) — for chronic insomnia. Some areas have NHS CBT-I services; private therapists and apps (Sleepio, Somryst) are alternatives.
• Neurologist — for suspected narcolepsy, parasomnias, or REM behaviour disorder.
• Mental health professional — when sleep is paired with significant anxiety or depression.

How to prepare for the appointment

• Keep a sleep diary for 1–2 weeks before the appointment: bedtime, estimated time to fall asleep, wake-ups, morning alertness, daytime energy.
• Note any medications, alcohol intake, caffeine timing, shift work, recent stressors.
• Bring a partner if possible — they often notice things (snoring, breathing pauses, restlessness) you can't observe yourself.

If your concern is dismissed

Sleep problems are still under-recognised in primary care. If you suspect sleep apnoea and aren't being referred for a study, ask specifically about the STOP-BANG questionnaire — it's the standard primary-care screening tool. You can also pay for a private home sleep test (~£200–£400 in the UK, usually with consultant interpretation).
