  • The Effects Of Circadian Rhythm And Sleep

    Circadian rhythm is defined as the biological clock in the brain that operates internal organs on a reoccurring 24-hour cycle (Myers, 2014). It is an advanced timing system relying on sunlight and darkness to control biochemical changes effectively to prepare the body to go to sleep (Laber-Warren, 2015). The suprachiasmatic nucleus, located in the hypothalamus, monitors the intensity of blue light waves and serves as the brain’s master clock (Myers, 2014). The master clock can be altered if it encounters bright lights at night including the digital screens of cellphones, TV sets, or laptops which have the same blue light waves as sunlight (Laber-Warren, 2015). This altercation sends messages to the brain thinking it’s the morning causing…

  • Personal Narrative: The Circadian Rhythm

    The Circadian Rhythm is your internal biological clock. It is how your body naturally reacts to the 24 hour day. When the morning approaches, your body temperature will rise and peak during the day, as the day comes to an end your temperature will lower. Last summer, sensing how close I was to college and knowing I would be in desperate need of money I decided to do what most students do, get a job.

  • Circadian Rhythm Experiment Report

     Experiment Procedure This experiment was conducted between 12PM and 5PM to reduce the effects of circadian rhythm on the participants, so the participants would be fully awake and cognitively aware at the time of the experiment. The subjects were instructed to arrive at the lab 1 hour prior to the beginning of the TSST. Upon arrival, they were taken to a waiting room where the head experimenter informed them about the process of the study. After verbal and written consent was received from all…

    by natural cadences called the circadian rhythm. BOOK 87 Our natural world operates predictably and rhythmically: poppies bloom in the morning, birds migrate with the seasons, and the sun rises and sets in 24-hour intervals. Our natural bodies are no different. They long to move with the earths natural pattern of light and dark. The superchiasmatic…

  • Rotating Shift Work Research Paper

    production, it’s not always good for the workers’ health. Some of the health challenges that rotating shift workers will experience in their career are obesity, insomnia, heart disease, diabetes, depression, and cardiovascular disease. The effects of a rotating shift work can be challenging for workers who are not aware of the health issues, and how their circadian rhythm works. The circadian rhythm is what controls an individual’s sleep pattern along with telling the brain to release melatonin,…

  • Essay On Gut Microbiome

    There is evidence that circadian misalignment and sleep loss, in the form of total sleep restriction, sleep deprivation and sleep fragmentation are physiological stressor. The changes in cortisol levels with loss of sleep, circadian misalignment. Therefore elevations in cortisol loss of sleep or acute circadian misalignment could be reflect hypothalamo-pituitary-adrenal (HPA) activation axis. This is problematic, Glucose metabolism impacted by a cortisol from inducing gluconeogenesis and…

  • Circadian Desynchrony

    The human circadian rhythm is a vital part of a person’s internal clock system. “Circadian desynchrony, is a sleep disorder where there is a mismatch with the body’s natural circadian rhythm and external environment.” (Choy & Salbu, 2011) This argues the fact that by switching time zones and environments that the body is not accustomed to will lead to irregular sleep cycles. Specifically when the body is moved across over two time zones it will lead to the perceived symptoms of jet lag (Choy &…

  • What We Loose-When We Don T Snooze Analysis

    These rhythms are controlled by a combination of two internal influences, homeostasis and circadian rhythms. First we examine homeostasis. According to the article “The Drive to Sleep an Our Internal Clock” presented by the Department of Sleep, Harvard University, homeostasis is the process by which the body maintains a “steady state of internal conditions such blood pressure, heartbeat and sleep-wake drive.”To demonstrate, from the time we get up to the time we go to bed our body accumulates a…

    the obesity epidemic continues to skyrocket, one diet that has received a lot of attention is Intermittent fasting (IF), or periods of voluntary abstinence from food and drink.24 In some places, IF has been practiced since the earliest of antiquity depending on culture and lifestyle. IF regimens are linked to certain health outcomes and influence metabolic regulation via effects on the circadian biology.24 Several cross-sectional and longitudinal studies have shown that IF has positive…

  • Jet Lag Research Paper

    What is jet lag? When an individual travels from one-time zone to another, it causes them to feel weary and exhausted, this temporary disorder is identified as jet lag, also known as desynchronosis. Our bodies have an internal clock which indicates when we must go to sleep and wake up. This “internal clock” is better known as the, circadian rhythms of the body. Circadian rhythms have an effect on the body temperature, sleep and wakefulness, and various hormonal changes. In order for an…
