Is a person"s subjective awareness including thoughts, perceptions, experiences of the world and self-awareness. Organisms have evolved biolgoical rhythms that are neatly adapted to the cycles in the environment. For example - bears are well known for hibernating during the cold winter months. Because this behaviour happens on a yearly basis - it is part of a circannual rhythm (literally meaning a yearly cycle) Are internally driven daily cycles of approximately 24 hours affecting physiological and behavioural processes. They inovlved the tendency to be asleep or awake at specific times - to feel hungrier during some parts of the day - and even the ability to concentrate better at certain times. Night shift workers and night owls aside - we tend to get most our sleep when it is dark outside because our circadian rhythms are circulated by daylight interacting with our nervous and endocrine systems.
