Morning circadian rythm (Morning person)

Being a morning person is related to waking up early and having more energy during the morning and is a trait that has sometimes been linked to mood, productivity and overall health.

Circadian rhythms are fundamental cyclical processes that occur in most living organisms, including humans. These daily cycles affect a wide range of molecular and behavioral processes, such as hormone levels, core body temperature, and sleep-wake patterns.

Chronotype describes an individual`s propensity to go to sleep earlier or later, and is a manifestation produced due to internal circadian cycles and the need for sleep, driven by sleep homeostasis.

There is significant natural variation among the human population with respect to sleep, and the chronotype is often divided between morning individuals (or "larks"), who prefer to go to bed and rise earlier; evening individuals (or "owls"), who prefer to go to bed later and get up later; and intermediates, who fall between the two extremes. Age and sex, as well as ambient light levels, among other environmental factors, affect the variability of this trait, but genetic variation is also an important factor.

Numerous studies have studied circadian rhythm disturbances, sleep and being an early riser or late riser and their effects on health and have identified that these traits are related to the development of some diseases.These traits have been identified as being related to the development of some diseases, especially metabolic and psychiatric disorders, although the conclusions that can be drawn from these are still limited and subject to the need for further research in the future.
