Chronotype vs sleep hygiene — biology or habits?
Sleep problems usually have two independent sources. Chronotype is biology: the genetically conditioned position of your sleep window. An owl forced to live on a lark schedule will be tired even with perfect habits — that is a body-clock conflict, not a discipline failure.
Sleep hygiene is habits: screens in bed, afternoon caffeine, irregular hours, no wind-down ritual. These factors damage sleep for every chronotype — and unlike biology, they can be changed within weeks.
Take both tests if you wake up tired: the chronotype test tells you when your body wants to sleep, and the sleep-hygiene test tells you what is sabotaging sleep quality regardless of timing. The most common conclusion? An owl with good hygiene sleeps better than a lark scrolling in bed.
