Circadian rhythm is also can be explained as the biorhythms that exhibits three important properties. Free-run – Well in the circadian rhythm runs without the presence of external cues also known as zeitgebers. Reset – Circadian clock often gets changed by the environmental conditions that includes the light and darkness of the day and also the temperature variations. Invariant – Sometimes circadian clock may run over an extensive range of physiologically relevant temperatures.
Though, studies are still going on to find why circadian clocks have been designed to keep on ticking for longer period when there is an absence of cyclical environment, it is a condition which is against the nature and usually has no presence in the universe. Circadian rhythm is very difficult to comprehend but its knowledge is very necessary to help in getting the right treatment.
However studies shows that circadian rhythm output paradigm is mainly depicted to move from left to right but it’s not certain as there are some cases in which it is usually working in the opposite direction.
Circadian rhythm sleep disorder can be treated and you can always go for some self-help remedies at its initial level.
Life runs on rhythms driven by circadian clocks, and disruption of these cycles is associated with serious physical and emotional problems, says Orie Shafer, a University of Michigan assistant professor of molecular, cellular and developmental biology.


Now, new findings from Shafer and U-M doctoral student Zepeng Yao challenge the prevailing wisdom about how our body clocks are organized, and suggest that interactions among neurons that govern circadian rhythms are more complex than originally thought. Yao and Shafer looked at the circadian clock neuron network in fruit flies, which is functionally similar to that of mammals, but at only 150 clock neurons is much simpler. Interactions among clock neurons determine the strength and speed of circadian rhythms, Yao says. Some of the fruit flies completely lost sense of time, and others simultaneously demonstrated two different sleep cycles, one following the group of eight neurons and the other following some other set of neurons. Disrupting the circadian clock through shift work is associated with diabetes, obesity, stress, heart disease, mood disorders and cancer, among other disorders, Yao says. The internal circadian clock of a Drosophila (fruit fly) can be synchronised using vibrations, according to research published today in the journal Science.
Also it is very less known to people around, so it becomes very necessary that you understand the basic composition of your circadian clock. These mainly inhibit the actions of your circadian clock and usually when the input part does not get enough exposure to environment cues it gives rise to circadian rhythm sleep disorder and associated problems. Previously, scientists thought that a master group of eight clock neurons acted as pacemaker for the remaining 142 clock neurons—think of a conductor leading an orchestra—thus imposing the rhythm for the fruit fly circadian clock.


The International Agency for Research on Cancer classified shift work that disrupts circadian rhythms as a human carcinogen equal to cancer-causing ultraviolet radiation. Our 24-hour biological cycle is responsible for many activities like brain wave, hormone production, regeneration of cell and temperature rhythm of the body.
They found that without the environmental cues, the orchestra didn't follow the conductor as closely as previously thought. It is mainly a group of cells that are located in the hypothalamus region of the brain and it helps in determining the sleeping patterns in human. Any changes in the normal functioning of our biological clock causes circadian rhythm sleep disorders. These things will surly help in maintaining a perfect sleep cycle of your body and you may avoid having any sleep disorder.
