Circadian Rhythms as a basis of mood disorder, in particular bipolar disorder.
Introduction:
The complex structure and the functions of the human body has been a subject of study by
a lot of individuals since a very long time. The curiosity of the human being supporting it,
further aids in discovering the secrets hidden behind the way a human being is.
Biological rhythms or circadian rhythms also make up one of the hidden secrets for the
functions of the human beings and scheduling of various tasks. The terms Circadian is
derived from Latin word Circa, “around” or “about” and diem or dies “day” meaning
literally “about a day” or “around a day”. This circadian rhythm is already built in the
complex human body but is regulated by external factors known as “zeitgebers”. The
primary or the most important zeitgebers is ‘light’ which helps human automatically start a
particular process in one’s life and controls various cycles at regular intervals. This may
include sleep/wake cycle, eating habits, seasonal affective disorder (SAD) or bipolar
disorder.
Scientists have long been researching the effects of disturbance of circadian rhythms and
its consequences on the life of a human being.
This paper also considers the facts that have been established in this area to identify and
discuss the process undergoing in a human being and its complexities with a particular
reference to circadian rhythms and bipolar disorder, its causes and how shall it be handled
to ease a human at such discomfort.
Literature Review:
Biological rhythms -By taking the two words and breaking them down into their separate
meanings a definition of biological rhythms evolves as, life which involves a recognizable
pattern of change over time. Biological rhythms control much of the body’s normal
functions, including performance, behavior, sleep and endocrine rhythms. These functions
are primarily regulated by the circadian clock, a cluster of nerves located on the
hypothalamus in the brain. The circadian clock relies on environmental cues to regulate its
function, primarily light cues from the day/night cycle. Abrupt shifts in routine, such as
shift changes, or travel resulting in jet lag can alter the sleep cycle and have a detrimental
effect on normal circadian rhythms. Additionally season changes, which are accompanied
by a decrease in the number of daylight hours, can negatively impact the function of the
