Introduction to Sleep Efficiency
Sleep efficiency is a crucial metric that measures how much of your time in bed is actually spent sleeping. This guide will walk you through every step of using our calculator to measure and improve your sleep quality.
Step-by-Step Guide
Recording Your Bedtime
Accurately record the time you went to bed. This should be when you actually turned off the lights and attempted to sleep, not when you got into bed.
- Use the time picker or enter manually in 24-hour format
- Be as precise as possible - even 15 minutes matters
- If you read or watched TV in bed, note when you actually tried to sleep
Recording Your Wake-up Time
Note the exact time you woke up for the day. If you use snooze, record when you first woke up, not your final rise time.
- Include any time spent awake in bed before getting up
- Account for different wake times on weekends vs weekdays
- If you woke before your alarm, record the actual wake time
Measuring Sleep Latency
Estimate how long it took you to fall asleep after lights out. This is called sleep latency.
- Average adults take 10-20 minutes to fall asleep
- If you didn't notice falling asleep, estimate conservatively
- Times longer than 30 minutes may indicate sleep issues
Tracking Nighttime Awakenings
Count how many times you woke up during the night and how long you were awake each time.
- Include bathroom trips, checking phone, or any consciousness
- Brief awakenings (under 5 minutes) still count
- If unsure, estimate based on how rested you feel
Understanding Your Results
Your sleep efficiency score appears as a percentage with interpretation:
- 90-100%: Excellent sleep efficiency
- 85-89%: Good, with room for improvement
- 75-84%: Fair, consider sleep hygiene changes
- Below 75%: Poor, may indicate sleep issues
