Tip: For the most useful report, log your sleep for at least 7 consecutive days. This gives healthcare providers enough data to identify patterns and make recommendations.
What's Included in Your Report
Log your sleep each morning for the best results. Here's what each field means:
- Bedtime: When you got into bed with the intention to sleep
- Time to Fall Asleep: Sleep latency - how long it took to fall asleep
- Wake Time: When you woke up for the day
- Time Awake at Night: WASO (Wake After Sleep Onset) - total time spent awake during the night
- Quality: Your subjective rating of how restorative your sleep felt
- Factors: Things that may have affected your sleep
Your data is stored locally in your browser. It won't sync across devices, but it's completely private.
Sleep Duration: Total time actually asleep. Calculated as time in bed minus latency and WASO. Adults should aim for 7-9 hours.
Sleep Efficiency: Percentage of time in bed actually spent sleeping. A healthy efficiency is 85% or higher. Low efficiency often indicates insomnia or sleep disruption.
Sleep Latency: Time to fall asleep. 10-20 minutes is normal. Falling asleep instantly may indicate sleep deprivation; taking over 30 minutes may indicate insomnia.
WASO (Wake After Sleep Onset): Time spent awake after initially falling asleep. Some brief awakenings are normal, but frequent or long awakenings reduce sleep quality.
