Discuss the disruption of biological rhythms 24m One example of disruption of biological rhythms is due to shift work and shift lag.This disrupts your sleeping pattern because it means you are required to be alert at night, so need to sleep during the day.This reverses and disrupts your circadian rhythm, becoming desynchronised where it is no longer entrained by EZ’s.
Shift Work This can involve working times where people would normally be asleep, and being asleep at times when people are normally awake. This causes a breakdown in the usual coordination between internal biological clocks and external cues. This requires a drastic change to.
Disruption of Biological Rhythms. Environmental factors influencing biological rhythms tend to change slowly, allowing the internal pacemakers to keep up. However, if the zeitgebers change quickly, problems can occur. Such problems include poor attention, slow reaction time and impaired reasoning skills and can arise from two features of modern life; shift work and jet lag.
Point- A mixture of environmental and biological determinism interact to control circadian rhythmsthis suggests nature and nurture both play a part. Explain- This is because we have evidence that our circadian rhythms are controlled by endogenous i.e. biological factors, however as exogenous Zeitgebers (for instance light) can have an impact on these rhythms; there is an element of the.

As outlined above, exogenous zeitgebers influence biological rhythms: these can be described as environmental events that are responsible for resetting the biological clock of an organism. They can include social cues such as meal times and social activities, but the most important zeitgeber is light, which is responsible for resetting the body clock each day, keeping it on a 24-hour cycle.Learn More

SAD can be discussed in an essay on disruption of biological rhythms. The menstrual cycle Obviously a cycle that lasts about one month, so this cycle is infradian. Like other rhythms, the menstrual cycle appears to be under the influence of both internal (endogenous) mechanisms, and external zeitgebers.. However, the sample size is.Learn More
Evaluating Circadian Rhythms. Research Support: Research has been conducted to investigate circadian rhythms and the effect of external cues like light on this system.Siffre (1975) found that the absence of external cues significantly altered his circadian rhythm: When he returned from an underground stay with no clocks or light, he believed the date to be a month earlier than it was.Learn More
Biological influences involve a child’s inherited traits, genetic make-up, thinking and brain development. There is evidence to suggest that a child’s genetic inheritance affects how a young child’s brain develops and through computer imaging technology it has been found that a child’s brain is poised to develop at an impressive rate of growth (Lindon 2005, p.11) allowing potential for.Learn More
This all supports that there are consequences to disrupting the biological rhythm and that in fact the exogenous does play a part in biological rhythms as there are consequences to it. However, this is a very small sample size as the researcher is only looking at one flight, and so it’s possible that not all people would respond the same to the long flight.Learn More
Insomnia and depression often goes hand-in-hand. The researchers also discuss that sleep disruptions and insomnia are bidirectionally-related, in which individuals with circadian rhythm disorders such as sleep phase syndrome, had or have a current history of depression (Franzen and Buysse, 2008).Learn More

These are rhythms with a period of greater than a day. The menstrual cycle is an example of an infradian rhythm. Infradian rhythms that occur as a result of seasonal changes, for example, migration and hibernation are called circannual rhythms. The menstrual cycle has a period of about 28 days, although the timing can vary according to environmental factors.Learn More
