Your answers put your sleep at the low end across the four things that make rest actually restore you: how long you get, how often it breaks, whether the habits around it help or hurt, and how you feel at nine in the morning. The picture this usually describes is a person running on what is left of last week rather than what last night gave them — functional, and slowly drawing down a reserve that does not refill on its own.

What it gives you, oddly, is a clear target. Poor sleep is the most common cause of tiredness, low mood, drifting attention and short temper, and it is also the one with the best-established fixes. Very little else in this catalogue responds as reliably to a change as sleep does.

Where the reading is honest about its limits: a score like this can come from a bad fortnight — a newborn, a deadline, a stretch of worry — or from a pattern years old, and the questionnaire cannot tell them apart. If the tiredness has no pattern at all, not worse after bad nights or better after good ones, that is the signal to get a blood test and rule out the things a page cannot see. The insights below start with the one lever that costs nothing and moves everything: a fixed wake time.
