How the Sleep Recommendation Algorithm Works
GoBe U calculates the recommended sleep duration based on several dynamic factors:
Your comfortable sleep duration set in the app
Your actual sleep duration over the past 6 days — if sleep deprivation is detected, the recommendation increases
Your stress level during the day — high stress increases the need for recovery
Your level of physical activity — intense activity increases the recommended sleep time
This means GoBe U doesn’t rely on a single night’s sleep but considers your overall physical state and accumulated sleep debt.
Why the Recommendation May Be High
A high sleep recommendation can be triggered by:
Consistently sleeping less than your set comfortable sleep duration
Experiencing increased stress during the day
Engaging in intense physical activity
Setting a personal sleep goal that may be higher than your actual physiological need
Why It May Be High Even If Sleep Quality Is 100%
The Sleep Recommendation and Sleep Quality are two separate indicators:
Sleep Quality reflects how well you slept (micro-awakenings, heart rate, sleep stability)
Sleep Recommendation reflects how much time your body may need to fully recover
It’s possible to sleep well, but not long enough — and the algorithm will still recommend more rest.
How to Reduce the Sleep Recommendation
Check your comfortable sleep duration set in the app (Settings -> My Habits -> Sleep Duration)
If you’re sleeping less than that value, the algorithm will try to compensate for the deficit
If the recommendation seems too high, try lowering that value by 30–60 minutes and observe the trend over a few days
After several days of sufficient sleep, the algorithm will gradually adjust the recommendation downwards
A high recommendation doesn’t mean something is wrong — it simply reflects your recent lifestyle, stress, or sleep debt.
