chronotype
Internal clock type
A chronotype is a person's natural inclination toward sleeping and waking at particular times—whether they're an early riser or a night owl.
The concept appears in sleep research and productivity advice: I'm an evening chronotype, so I do my best work after midnight.
Some systems classify people as lions, bears, wolves, or dolphins based on their sleep patterns.
