Sleep, Sleep Disorders, and Biological Rhythms by Charles.
In their work, Your Guide to a Healthy Sleep, National Institutes of Health pointed out that sleep is very important to human existence, so important that one-third of a person’s life is spent doing it (1). In Sleep, Sleep Disorders, and Biological Rhythms, Amlaner said, “Sleep is a required activity, not an option” (19).
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.
The best example of a circadian rhythm is the sleep-wake cycle, associated with which are many cyclical changes with active and dormant periods, for example body temperature and urine production. These rhythms allow animals to prepare for predictable daily environmental changes, such as night and day.
Ultradian rhythms last fewer than 24 hours and can be found in the pattern of human sleep. This cycle alternates between REM (rapid eye movement) and NREM (non-rapid movement) sleep and consists of five stages. The cycle starts at light sleep, progressing to deep sleep and then REM sleep, where brain waves speed up and dreaming occurs. This repeats itself about every 90 minutes throughout the.
Your body has an internal clock that helps regulate when you eat and sleep, and even how you feel. Read on to learn more about biological rhythms.
Describe and Evaluate Circadian Rhythms Essay Describe circadian rhythms (8marks) Circadian rhythms occur every 24 hours; an example of a circadian rhythm is the sleep-waking cycle. We are diurnal animals who are active during the daytime and asleep at night, other animals are nocturnal they are active at night but asleep during the day.
There are three main biological rhythms, which are called infradian, circadian and ultradian. Ultradian rhythms occur multiple times in one day. Circadian rhythms are cycles, which occur once a day, so within the 24 hours such as the sleep-wake cycle. Infradian rhythms are less frequent once in a day such as the menstrual cycle or hibernation.
Consequences of Disrupting Biological Rhythms (A2 Psychology Sleep) Essay.the consequences of disrupting biological rhythms (24) A rhythm is something that is regularly repeated. All living organisms experience rhythmic changes which tend to coincide with seasonal or daily environmental changes.

The Relationship Between Sleep Patterns Psychology Essay. 3570 words (14 pages) Essay in Psychology. Circadian rhythm and sleep: An important factor which plays a vital role in everyone’s sleep is circadian rhythm, a 24 hour internal biological clock, which is also known as the circadian pacemaker.
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.
Three basic processes underlie sleep regulation: first biological mechanisms control is a homeostatic process mediating the rise of sleep tendency during waking and its dissipation during sleep; another mechanisms control is an ultradian process occurring within the sleep episode and represented by the alternation of the two basic sleep states, non-REM sleep and REM sleep.
Discuss the consequences of disrupting biological rhythms Biological rhythms are controlled by endogenous pacemakers, which are our internal biological clocks and these rhythms are also affected by exogenous zeitgebers, for example light, food and noise.
