Essay on Discuss the Disruption of Biological 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.

Essay on Discuss the Disruption of Biological Rhythms 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 has always been one of my favourite topics, both to study and to teach. We begin with a look at biological rhythms in general, looking at research into the different types. We then consider what happens when these rhythms get disrupted, most likely through jet lag or shift work. One of the rhythms we consider is the ultradian rhythm of sleep.

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.

However, in learning about endogenous pacemakers and exogenous zeitgebers students would inevitably study how internal biological rhythms and external factors (e.g. travel across time zones, changing daylight hours, shift working) affect the sleep-wake cycle.

Recent research by Yakazaki found that isolated lungs and livers, and other tissues grown in a lab still persist in showing circadian rhythms. This suggests cells are capable of maintaining a circadian rhythm even when they are not under the control of any brain structures and that most bodily cells are tuned in to following a daily circadian rhythm.

There are a lot of research into circadian rhythms, including the role of endogenous pacemakers (SCN) and of exogenous zeitgebers (light), with the majority being controversial animal research. One of the most useful and influential animal research into free-running rhythms is by Zucker et al (1976).

We have been impressed with the need for investigations into how internal as well as external social and environmental factors may disrupt the integrity of biological rhythms. We now present the concept of a “Zeitstorer” (time disturber) which is envisioned as a physical, chemical, or psychosocial event which acts as a source for circadian rhythm disruption.

With rhythm and blues, there is a song for every emotion, so most of the time the songs can be very relatable. The songs have a variety of subjects like sex, work, and even drinking. In this paper I will briefly discuss how rhythm and blues started, how it evolved into today’s music and why I like it so much.
