Boivin, 2009 this paper will emphasize normal biological rhythms. Biological Rhythm Essay.Every living organism has a physiological rhythm. In reality, however, we are subjected to a wide variety of changing stimuli all the time. Therefore a drastic change in sleep schedule caused by extensive occurrences of jet lag, or multiple shift changes may result in a disruption of circadian rhythm function. Conclusion, there are four types of biological rhythms that regulate cycles within the body. The primary type, circadian rhythms, controls performance, endocrine rhythms, behavior and sleep timing, and is regulated by the circadian clock, a collection of nerves located on the hypothalamus. Despite concerns that permanent night-shift workers' circadian rhythms never fully adjust to a nocturnal lifestyle, studies have shown that permanent night-shift workers report fewer sleep or social-related problems than rotating-shift nurses. When lifestyle treatments and good sleep hygiene dont work, your doctor may prescribe medication. Since many of our biological cycles follow an approximation 24-hour rhythm, even in the absence of external stimuli, it follows that there must be some kind of internal biological clock. The majority of people fall somewhere between the two types.
For the disruption. Have a key role in controlling biological rhythms as the removal of one would begin to randomise and alter biological rhythms. Discuss the effects of the disruption of biological rhythms. Kuttsson et al (1986) found individuals who worked shifts for more than 15 years were.
This shows that stress can make the SCN less responsive to light. Consequently, engaging in shift work often induces conflict between people's internal body clocks and the actual time of day. Similar to the ultradian cycle the infradian rhythms are not directly linked to circadian and diurnal rhythms. These conflicts make shift workers work when their body is preparing for sleep, and sleep when their body is preparing for wakefulness. AO2 Evidence to support this comes from Aschoff. The question that arises is when do health problems, specifically mood disorders; develop as a result of shifts in biological rhythms, and what combination of environmental factors leads to those shifts? Biological rhythms are the natural cycle of change in our bodys chemicals or functions. Both cycles have a duration of approximately 24 hours. N., Mineka,., Hooley,. Cherry's commentary "Depression Caused by Lack of Sleep? Additionally the rats in the study showed a tendency to gradually adjust to changes in the feeding pattern, much as shift workers gradually altered their sleep/wake patterns after a change in working hours.
