📋 Sleep Quality Quiz — How Good Is Your Sleep?
10 questions based on clinical sleep science. Get your sleep quality score and discover what's affecting your sleep the most.
What We Measure
Understanding Your Sleep Score
Based on the Pittsburgh Sleep Quality Index (PSQI) scoring framework.
Very good sleeper. Your sleep habits are solid. Minor tweaks may provide small gains but nothing is fundamentally broken.
Mostly good sleep with occasional issues. Focus on consistency — wake time and sleep schedule regularity will sharpen your quality.
Significant sleep disruption. Multiple factors are affecting your sleep. CBT-I techniques will make a measurable difference. Consider a sleep diary.
Severely disrupted sleep affecting daily life. Consult a GP or sleep specialist. Conditions like insomnia disorder or sleep apnoea should be ruled out.
When to See a Doctor — Red Flags
Self-help and CBT-I techniques address most sleep problems. But some sleep issues require medical assessment. See a GP or sleep specialist if any of the following apply:
Frequently Asked Questions
Sleep Quality Test vs Sleep Quantity — What Matters More?
Both matter, but quality is often undervalued. You can sleep 9 hours and wake exhausted if your sleep architecture is disrupted — too little deep sleep (slow-wave sleep), too little REM sleep, or frequent micro-arousals caused by sleep apnoea, environmental noise, or alcohol. The Pittsburgh Sleep Quality Index (which this quiz is based on) specifically measures quality across 7 domains because researchers recognised that sleep duration alone is a poor predictor of next-day function.
Signs You Have Poor Sleep Quality
You may have poor sleep quality even if you sleep 7–9 hours if you experience: waking unrefreshed most mornings, difficulty concentrating in the afternoon, falling asleep immediately when sedentary (under 5 minutes), needing an alarm to wake (suggests sleep is still incomplete), relying on caffeine to function before noon, and emotional volatility disproportionate to daily events. A PSQI score above 5 on this quiz suggests clinically meaningful poor sleep quality requiring attention.
Am I Getting Enough Deep Sleep?
Deep sleep (slow-wave sleep, stages N3) should constitute roughly 20–25% of total sleep time — about 90–120 minutes for a 7.5-hour sleep. Deep sleep is when physical restoration occurs: growth hormone is released, tissue is repaired, and the immune system is strengthened. Signs of deep sleep deficiency include persistent physical fatigue, frequent illness, poor muscle recovery after exercise, and high evening cortisol. Deep sleep naturally declines with age — adults over 60 may have only 5–10% deep sleep — which is a key reason older adults feel less restored by sleep.
