Sleep Records: Beyond 'How Many Hours' to What Actually Matters

Total hours slept is a small part of sleep quality. Wake-ups, sleep onset time, restfulness, and the pattern across weeks tell more. A brief sleep record — kept for 2-4 weeks when concerned — makes chronic sleep problems visible in a way memory rarely does.

What to record each morning

• Field: Time to bed · Note: When lights off
• Field: Time to sleep (estimate) · Note: Sleep onset latency
• Field: Number of wake-ups · Note: Rough count
• Field: Time awake before intended · Note: Early morning waking pattern
• Field: Total hours slept · Note: Estimate
• Field: Feels refreshed (1-10) · Note: Subjective quality
• Field: Daytime sleepiness (1-10) · Note: Impact
• Field: Any caffeine, alcohol previous day · Note: Common disruptors
• Field: Exercise timing · Note: Late exercise disrupts
• Field: Screen use before bed · Note: Blue light effect

The specific patterns and what they suggest

• Difficulty falling asleep (> 30 min) with racing thoughts — anxiety pattern.
• Waking at 2-4am and unable to return to sleep — depression pattern.
• Multiple brief wake-ups, unrefreshed, snoring — sleep apnea.
• Racing heart, tingling waking you — restless legs or nocturnal anxiety.
• Nightmares and vivid dreams — REM behavior or PTSD.
• Waking to urinate 2+ times — nocturia (multiple causes).
• Sleeping 10+ hours and still tired — hypersomnia or depression.
• Cannot sleep even when exhausted — insomnia proper.

Sleep hygiene — the specific habits

• Consistent bed and wake time (weekends included, within 1 hour).
• Dark bedroom (blackout curtains if streetlight).
• Cool temperature (18-22°C).
• No screens for 30-60 min before sleep.
• No caffeine after 2pm.
• Alcohol early in evening not late (alcohol disrupts second-half sleep).
• Regular exercise but not within 3 hours of bed.
• Bed for sleep and sex only — not work, not screens.
• If not asleep in 20 minutes, get up briefly, do quiet activity, return.

What NOT to do

• Long naps late in day (short 20-min OK).
• Clock-watching if unable to sleep.
• Alcohol as sleep aid (often worsens quality).
• Over-the-counter sleep aids for extended use.
• Setting expectation of 'perfect sleep' (perfectionism worsens insomnia).

When to consider sleep study

• Loud snoring with pauses (sleep apnea).
• Excessive daytime sleepiness affecting function.
• Uncontrolled BP despite treatment (sleep apnea often).
• Uncontrolled diabetes.
• Restless legs disrupting sleep.
• Suspected narcolepsy (extreme daytime sleepiness, sudden sleep attacks).
• Suspected parasomnia (violent behaviour during sleep).

The specific interventions for insomnia

• Cognitive behavioural therapy for insomnia (CBT-I) — first-line, strong evidence, often more durable than medication.
• Sleep restriction therapy — counterintuitive but effective.
• Stimulus control therapy.
• Relaxation training.
• Medication as short-term bridge, not long-term solution.

Medication considerations

• Melatonin — modest effect, safe for short-term shift regulation.
• Non-benzodiazepine hypnotics (zolpidem, eszopiclone) — short-term use.
• Benzodiazepines — real dependence risk with regular use.
• Sedating antidepressants (mirtazapine, trazodone) — for depression + insomnia.
• Antihistamines — variable effect, cognitive fog next day.

Ambient factors often overlooked

• Bed partner's snoring or restlessness.
• Pets in bedroom.
• Ambient noise (traffic, neighbours).
• Mattress and pillow quality.
• Room temperature and humidity.
• Light pollution.

The 4-week sleep record for a specialist

Two weeks of self-tracking often reveals patterns the person didn't see. Four weeks with an accompanying diary of daytime function is what a sleep specialist wants at the first visit. Sleep tracking apps and wearables help; a plain notebook works too. The specific data matters more than the medium.
