Sleep Efficiency (Coming Soon)

Description
Sleep Efficiency measures how much of your time in bed is actually spent asleep. In simple terms: if you were in bed for 8 hours and slept for 7 hours, your sleep efficiency is about 87.5%. Higher efficiency generally reflects more consolidated sleep, while lower efficiency suggests frequent awakenings, long time to fall asleep, or time in bed that doesn’t translate into sleep.
Why it matters
Low sleep efficiency can show up even when total time in bed is “long.” It often correlates with non-restorative sleep, daytime fatigue, and difficulty maintaining consistent sleep patterns. It’s also a useful signal when tracking insomnia or sleep fragmentation over time.
Common reasons efficiency is low
Stress and rumination (long sleep latency)
Alcohol (more awakenings later in the night)
Late caffeine
Overheating or uncomfortable sleep environment
Sleep apnea or other sleep disorders (fragmentation)
Irregular sleep schedule
How to improve (practical)
Keep a consistent wake time, limit late caffeine/alcohol, and avoid spending excessive time in bed “trying” to sleep. If efficiency is persistently low with symptoms, it may be worth screening for sleep apnea or insomnia patterns.
