1. High WASO (Night Wakings)
WASO above 30 minutes is the most common single cause of low scores. It directly reduces the WASO component (15% weight) and indirectly reduces efficiency. Primary causes: alcohol within 3 hours, bedroom above 70°F, sleep apnea, stress. Fix: cool your bedroom, eliminate alcohol for 7 days, track daily.
2. Low Sleep Efficiency
Efficiency below 80% tanks both the efficiency component (30% weight) and your duration component. Fix: sleep restriction therapy - temporarily limit time in bed to your actual sleep time, extend by 15 minutes per week as efficiency improves above 85%.
3. Undiagnosed Sleep Apnea
Affecting 20%+ of the population, sleep apnea creates hundreds of micro-arousals per night that massively elevate WASO and destroy sleep architecture. Key signs: snoring, morning headaches, daytime sleepiness. Our questionnaire flags sleep apnea risk.
4. Behavioral Habit Combinations
No single habit causes catastrophic scores, but combinations do. Caffeine at 4pm + alcohol at 10pm + bedroom at 72°F + phone in bed = every component dragging simultaneously. Our behavioral questionnaire identifies your specific combination.

Calculate My Sleep ScoreFrequently Asked Questions
What is a bad sleep score?
Scores below 55 are poor - clinically significant disruption. Scores 55-69 need improvement. Both warrant systematic intervention.
Can I fix a low sleep score in one night?
Some factors improve immediately (cool bedroom → immediate WASO reduction), but most require 1-3 weeks of consistent change.
Should I see a doctor for a low sleep score?
If consistently below 60 after 3-4 weeks of behavioral improvement, or if you show signs of sleep apnea, yes - consult a healthcare provider.
