Our biological clock tells our body and mind when to go to sleep and when to wake. If that inner clock doesn’t quite synchronize with life’s obligations, normal people will be able to adapt. But they may not always feel great throughout the day.
Owls (or night owls or evening types) feel best and most alert during late hours. They prefer to have their main meal late in the day and usually skip breakfast. A cup of coffee is often their morning meal. But they do need an alarm clock in the morning to ensure they rise to meet their daily obligations.
In contrast, larks (or morning types) wake up early and are at their best during the first part of the day. They eat breakfast and prefer to retire relatively early, after a light dinner.
Owls predominate because humans have an inner clock with a period slightly longer than 24 hours. That causes a tendency to stay up a bit later and wake up later each day. Owl and lark tendencies are natural and are not considered problems, unless they cause sleep deprivation or interference with daily routines.
