Generally humans who are healthy experience rhythmic variations in their body temperature and this happens in each and every day. Any disruption in this natural time pattern can cause the zeitgebers to act upon the circadian system to restore it to the normal state and in synchrony with the time patterns or discourage the adjustment to the newly acquired routine.
The study of the biological temporal rhythms is referred to as chronobiology. HJK Outline and evaluate the consequences of disrupting biological rhythms 24marks Answer: This is because the dorsal portion of the SCN needs several cycles to fully resynchronise, as it is less sensitive to light.
Boivin et al found that after 3 days participants exposed to very bright light had an advancement in circadian rhythms by 5 hours, those exposed to bright light and room light had advanced by 3 hours and 1 hour and those that remained in dim light had circadian rhythms that had drifted 1 hour later than normal This suggests that rhythms can be retrained using light and reduce the negative effects of decreased alertness.
The impact of the desynchronisation of internal chemical cycles, controlled by the endogenous pacemakers, such as the SCN, and exogenous zeitgebers, such as light, can be far reaching. Discuss the consequences of disrupting biological rhythms.

The results obtained from these studies show that the human body is governed by some built-in time setters or clocks which is referred to as an internal body clock. A significant relationship has been found between shift work and organ disease. In a normal condition, these circadian rhythms are liked or synchronised together by the internal biological clock and are entrained to an external clock time by the external time cues which are the synchronizing effects to the physical world which we live in.
It is seen that more than body functions operate between their maximum and minimum values in a day. This results since the body is trying to change the way in which it was used to operate during daytime when it was most active to the night shifts which now become the most active shifts where the body should be alert.
Dim lighting which is mainly used in places such as hospitals failed to keep participants awake.

This can be in minutes considering the stages of sleep and in days while considering the female menstruation cycle. This may be due to the direct effect of desynchronisation in the circadian rhythm.
To exemplify the effect that shift work has upon biological rhythms, Knutsson et al found a relationship between shift work and organ disease. It was found that individuals who worked night shifts for more than 15years were three times more likely to develop heart disease than non-shift workers, suggesting that the disruption of biological rhythms can lead to various health implications.
Research into the disruption is highly valuable as it has applications for reducing errors caused by decreased alertness such as the Chernobyl disaster ; for example the use of artificial lighting to re-set rhythms of shift workers.
