# Chronotype

Chronotype is your natural preference for earlier or later sleep and wake times, from strong morning types to strong night owls.

It is partly genetic and shifts with age: teenagers and young adults tend to run late, and most people drift earlier after about 50. Morning light can move it a little earlier; a steady wake time matters more than fighting it.

Also called: Morning person, Night owl.
