クロノタイプクイズ

Your chronotype is largely genetic and shifts naturally with age — children tend to be early birds, teenagers become night owls, and older adults shift earlier again. You cannot fundamentally change it, but you can nudge your schedule with morning light exposure, meal timing, and consistent sleep habits.

Yes. Research has identified hundreds of gene variants associated with chronotype, including PER2, CRY1, and CLOCK genes. Twin studies show roughly 50% of your chronotype is inherited. The rest is influenced by age, light exposure, and lifestyle.

Lions thrive with early-morning deep work (6-10 am). Bears are most productive mid-morning to early afternoon (10 am - 2 pm). Wolves hit their stride in the late afternoon and evening (4-8 pm). Dolphins do best with a structured mid-morning window (10 am - 12 pm) and should avoid late-night stimulation.

Chronotype influences when your metabolism is most active. Lions digest best with an early dinner. Bears do well with standard mealtimes. Wolves often skip breakfast and eat later — which can work if meals are balanced. Dolphins benefit from regular, timed meals to stabilise their irregular rhythms.
