Circadian Rhythms Essay

can impact nurses’ performance and health, especially for nurses who work at night (Kudielka Buchtal, Uhde, & Wüst, 2007). When nurses work at night, their normal circadian rhythms (biological clock) will be disturbed because of the change in sleep patterns. Therefore, there will be “a mismatch between the endogenous, internal circadian timing system and the external environmental synchronizers” (Kudielka et al., 2007, p.92). This means that nurses’ biological functions will be disturbed by the changes

Provide a basic overview of the country that the participant is competing in and any characteristics that may affect the competition or performance in the participant 's sport (i.e. location, climate, geography) Located in Southern Asia, Sri Lanka (formerly known as Ceylon) is an island found in the Indian Ocean, south east of India. Sri Lanka is home to a diverse range of religions, languages and ethnicities (Domros, 1998). Sri Lanka’s tropical climate is described as quite hot. The client’s destination

Question: How can sleeping patterns be more effectively used to increase energy in high school students? Intro: Let’s start by talking about zombies. What classifies a zombie? Zombies are usually defined as the living dead; “deceased” organisms that come back to life and are often propelled to eat human flesh by some sort of virus or disease. They are typically seen as slow and stupid; no thinking just doing with little to no energy; never sleeping. All of these traits that can be seen in zombies

through biological processes regulated by internal circadian clocks, there are periods throughout the day where a person feels either sleepiness or wakefulness. There are different times during the day where the circadian rhythm rises and falls, causing a change whether a person feels awake or not. These circadian clocks range between the different age groups of people. When it comes to adolescences, a biological shift has caused their circadian clock to be pushed back by two hours, causing them

Light, is a type of wave that has electromagnetic radiation, traveling in transverse waves at a different wavelength from the sources to be visible to the human eye. With the presence of light, human could see things with the sense of sight. The light come from different sources but mainly from sunlight which enable process of photosynthesis where plants make their food and sustain life on earth. Light, is also a sign of civilization, showing the presence of human whenever light is seen from the

diseases, cardiovascular diseases, diabetes, metabolic disturbances, cancer, etc. Although the mechanism of how these diseases are caused by shift work is still not well elaborated, it was shown by most of the studies that factors disturbing the circadian rhythm of the workers play a major role (1-3).

The health consequences of lack of sleep and excessive daytime sleepiness affect 50 to 70 million Americans annually. Sleep deprivation costs the United States 15 billion dollars annually in health care. In addition, industry spend $50 billion dollars in lost productivity (NIH, 2004). Mental health and sleep are closely connected. Insomnia is the most commonly reported mental health complaint in the United States. Mental health problems can affect the amount of sleep, the type, and the time spent

Deprivation of sleep has been linked to a variety of health issues from type II diabetes, obesity, and cardiovascular diseases, to mental health issues such as depression (Porkka-Heiskanen, Zitting & Wigren, 2013). The busy lifestyles of Western culture in the 21st century have increasingly deprived individuals of sleep. This could potentially be a contributing reason that there has been an increase of obesity in cultures such as that of the United States. But what makes humans sleep? Why, as a species

called, “Daily Activities and Sleep Quality in College Students”. The purpose of this study was to analyze the relationship between sleep and social rhythms. The researchers acknowledged that, “It has long been recognized that consistent and qualitatively satisfying sleep is largely dependent on a robust and well entrained endogenous circadian rhythm” (Carney, Edinger, Meyer, Lindman, and Istre, 2009). The researchers further explained that in their study they were going to attempt to establish a

serious sleep disorders (Schomerus and Korf 2005). This is because melatonin is a huge regulator of the circadian rhythms in the body. Therefore, an imbalance will cause serious health risks at a molecular level. In vertebrates, melatonin is synthesised in the pineal gland (Foulkes et al. 1997). In mammals however, the pineal cells found within the gland are not light reactive nor do they have a circadian clock imbedded inside (Foulkes et al.
