Frequently asked questions
Can my chronotype change?+
The genetic baseline is fixed, but ~30–60 minutes of phase shift is achievable through morning light, melatonin timing, and consistent wake times.
Why do teens sleep so late?+
Puberty biologically delays the circadian phase by ~2 hours. It's not laziness — it's neuroendocrine.
Is being a Wolf bad?+
No — but Wolves living on a Lion's schedule pay a 'social jet lag' tax linked to obesity, mood disorders, and cardiometabolic risk.
What are the four chronotypes?+
Dr. Michael Breus popularized Lion (early), Bear (middle, ~55% of people), Wolf (late), and Dolphin (light, anxious sleepers). They map loosely to morning, intermediate, evening, and irregular types in research.
How accurate is a chronotype quiz vs. genetic testing?+
Validated questionnaires (MEQ, MCTQ) correlate ~0.7 with melatonin-onset markers — strong enough for behavior change. Genetic tests (PER3, CLOCK genes) add precision but rarely change recommendations.
What's the best work schedule for a Wolf?+
Start work after 10 AM if possible, schedule deep work for 5–9 PM, and protect a late-but-consistent bedtime. Early starts cost Wolves 20–30% of cognitive output.
Can shift workers use chronotype info?+
Yes — Lions struggle most with night shifts; Wolves tolerate them best. Matching shift to chronotype reduces error rates and improves long-term cardiovascular health.
