How to Track Sleep for Performance

Of everything you can track in Grow, sleep is the one that quietly governs the rest — your focus, mood, willpower, and recovery all ride on it. That is why it carries the most weight in your Vitality Score. The Sleep tracker logs your nights, shows the trend, and surfaces two signals most people never see: sleep debt and bedtime consistency.

Section Protocol

What to log and what it shows

Record each night's sleep, and the tracker builds a rolling chart plus two derived cards. Sleep debt accumulates the hours you fall short of your target, so a run of six-hour nights shows up as a growing deficit rather than a vague tiredness. Bedtime consistency tracks how steady your sleep timing is — because a regular schedule often matters as much as raw hours. Together they turn "I feel tired" into something specific you can act on.

Section Protocol

Reading the signals

Watch the debt, not a single night. One short night is easily absorbed; a debt building over a week is what erodes your performance and your other habits. Consistency is the quieter lever — going to bed at wildly different times fragments sleep quality even when the hours look fine. If your Vitality Score is dropping, the sleep cards are usually where the cause is hiding.

Worked example

Meera cannot understand why her focus and mood have slumped, though nothing obvious has changed. The Sleep tracker makes it plain: a quiet debt has built up over ten days of late nights, and her bedtime has drifted by two hours. She sets a consistent lights-out, holds it for a week, and the debt shrinks — and her Vitality Score, focus, and patience all recover together, because they were all resting on the same foundation.
