What is Biological Rhythm?
Biological Rhythm is periodic biological fluctuation in an organism that corresponds to, and is in response to, periodic environmental change (The Editors of Encyclopædia Britannica, 2014). An example could be of the relative position of the Earth to the Sun and to the Moon with the effects of the changes like day changing to night. There are daily rhythms to many of our physiological functions and activities....our sleep, body temperature, alertness, neurotransmitter levels, etc (Chudler, 2014). Biological Rhythms adjust the most important functions in an organism. There are three types of biological rhythm, Infradian rhythm, Ultradian rhythm and Circadian rhythm.
Types of Biological Rhythm
Circadian
Circadian is latin word having the root word “circa” meaning about and “diem” meaning a day or 24 hours, the definition is changes that happen approximately every 24 hours (Hedge, 2013). That could be physical, mental behavioral or etc. This type of rhythm is endogenous meaning inside, proceeding from with or internally. Some examples of circadian in plants are how it maintains the flowering reaction to seasons and photosynthesis, in mammals the circadian clock helps function the activities such as sleeping, waking, feeding and determining the if an animal is nocturnal or diurnal. Circadian rhythms present even in the absence of environmental cues such as light, temperature or social cues (Victor, Biological Rhythms, 2014). Since circadian is endogenous than this rhythm is inherited or genetic and is dominated by our biological clocks that are rested and adjusted by cyclical environmental cues called Zeitgebers. Usually their cyclical having the intensity and frequency change at different part...

...me sleepiness but with no cataplexy. The different forms of narcolepsy are stimulants physician prescribe to keep you active during the day, antidepressants to help cure cataplexy and lastly lifestyle changes.
Parasomnia
This disorder involves un favored events during falling asleep or waking up also this includes strange movements, behaviors, emotions or dreams and having the person remembering none of this event happening. Sleepwalking, night scares; sleep talking, sleep paralysis and sleep eating occur in the parasomnia disorder and are some of the basic symptoms (Retini, 2014). Some risk factors are genetic such as if a person in your family sleep walked then you likely to sleepwalk also along with stress, post-traumatic stress disorder, medications or drug abuse (Retini, 2014). Treatment for this disorder would be to talk sleep disorder specialist for help.
There are many ways in which scientists and researchers try to understand the molecular uniqueness and physiology of living organisms. One of these ways is the Circadian clock, this clock transfers the physiology and behaviors of mammalians into rhythms that are coordinated with the 24hr solar system. This system can be affected by environmental factors such as the food, temperature and parasites. The circadian rhythms play a role in gene expression to produce protein. Gene expression is displayed through the central dogma of (DNA RNA protein). How the clock work with the 24hr solar day is that it allows gene expression every 24hr to tell when a physiological process is most active. And any damage made to the DNA is more effective
The symptoms of narcolepsy include cataplexy, persistent daytime sleepiness, sleep paralysis, and hypnagogic hallucinations. Cataplexy is “a loss of skeletal muscle tone without loss of consciousness” (77). These cataplectic attacks often occur at emotional times. Such events could be laughter, sexual intercourse, physical exertion, and anger. Daytime sleepiness can make narcoleptics fall asleep at inappropriate times and although they may be refreshed after naps they are soon tired after. Sleep paralysis is the inability to move prior to falling asleep or waking. Finally, hypnagogic hallucinations are vivid dreams before sleep or when extremely tired.
THESIS STATEMENT: Narcolepsy is a sleep disorder that has a specific medical definition, life-changing symptoms, and there are ways in how people treat it.
Nature and life are full of rhythms. Rhythms in nature include: day and night, seasons, tides, and lunar and solar cycles. Humans are driven by rhythms like: heartbeats, breathing rates, sleep patterns and brain rhythms which include chemical and hormonal secretion. Without rhythms, life would be uncontrollable and chaotic.
Tomas Izquierdo has not slept since 1945. Due to an attack of encephalitis, an inner brain inflammation, his ability to fall asleep was lost at the age of 13. Although he rests with his eyes closed, his brain patterns are those of someone who is fully awake and aware. He has memory problems and very sensitive eyes, but is otherwise completely normal. To relax, he usually uses transcendental meditation from about three or four AM until the morning (Coleman 94).
Circadian rhythms also known as sleep/wake cycle or body clock, is a natural, internal system that is designed to regulate our feelings
Narcolepsy is a sleeping abnormality in which a person experiences sudden attacks of sleepiness during the day. Narcolepsy is an often-inherited neurological sleep disorder caused by the brains inability to regulate a stable sleep-wake cycle. (Turkington & Harris). People who suffer from this abnormality usually experience attacks of muscle weakness or paralysis and occasional dreamlike experiences while awake. Narcolepsy is a disturbance of the portion of sleep called rapid eye movement (REM) sleep into the waking period. During normal REM sleep, the muscles become deeply relaxed and the nerves to the muscles are basically paralyzed. The normal sleep period begins with about 90 minutes of non-REM sleep before REM sleep begins. But for a person
Sleep disorders are a very serious problem for a lot of people. It affects a lot of people 's lives, requiring them to have to live a very different life than the average person. The five most commonly known sleep disorders are insomnia, sleep apnea, sleepwalking, and narcolepsy. Sleep insomnia is when you have trouble falling asleep or staying asleep even when you have a chance to do so. Sleep apnea is when you have trouble breathing when you’re asleep. Sleepwalking is when you’re in a deep sleep and you start to walk around or perform some kind of complex behavior. People that are affected by these disorders have a very hard time either getting to sleep or staying asleep. I will be explaining what all of these disorders are and how they affect
You have continuing problems falling asleep, have difficulty falling back to sleep after waking, and often wake up very early in the morning.
The circadian rhythm keeps an organism’s body in sync with night and day in order to keep the body systems in order. The word circadian comes from the latin word circa diem, which means about a day (JCI). It was first identified in 1729 by Jean Jacques d’Ortuous de Marian, a french astronomer, geophysicist, and more importantly, a chronobiologist. Chronobiology is a type of science that examines the natural phenomenons and rhythms such as the circadian rhythm (Serendip). He was born on November 26, 1678 and died on February 20, 1771. With his interest in chronobiology, the study of day and night’s effects on living organisms, he proved the existence of circadian rhythm in plants. To come to this conclusion, he observed that the a type of plant, the Mimosa pudica, still opened its leaves during the day and closed them at night when put in a completely dark environment. With this shocking discovery, he “concluded circadian rhythms persist[s] without environmental cues” (The Guardian).
Cataplexy is under the umbrella of narcolepsy that was named by Lowenenfelt in 1902. According to Mayer and Dauvillier, there are two types of narcolepsy: those with or without cataplexy (2013), which is sudden and transient episodes related to muscle weakness despite being consciously aware of their surroundings. Doctors can distinguish type 1 narcolepsy by the low cerebrospinal fluid hypocretin level, while type 2 is based on a series of tests in which more than two sleep onset of rapid eye movement (REM) period is observed than those of normal (Nixon et al., 2015). In other words, type 1 is just based on low cerebrospinal fluid while type 2 is based on their sleep onset during REM. This disease starts before 25 years old in 80 % of most patients causing intense sleep attacks that can occur two times a day for less than 30 minutes with a 2 hour interval (Mayer et al., 2013). These sleep attacks show to be problematic, which is why it is thought it could be a caused
There are three forms of sleep paralysis. Ramsawh (2005) found that when it occurs in non-narcoleptic individuals it is known to as isolated sleep paralysis (ISP). Another form is referred to as familial sleep paralysis, in which it is similar to ISP, but genetically transmitted (Levitt, 2009). The final form of sleep paralysis is narcoleptic sleep paralysis, which occurs as a symptom of Narcolepsy (Levitt, 2009). Isolated sleep paralysis episodes are characteristic with “infrequent attacks and a negative family history”, and familial sleep paralysis with “more frequent attacks and a positive family history” (Powell, 1998, p. 239). Each form of sleep paralysis is unique and different in the causes and symptoms they possess.
Our bodies rely on two different things to let our bodies know when we need to be asleep. One is called the circadian rhythm, which is the physical, mental and behavioral changes that follow a twenty four hour cycle, that revolves around the light and dark of the day. Basically, our bodies are like our own little clocks which are controlled by a part of the brain called the suprachiasmatic

Did you ever awaken and find yourself unable to move? Perhaps you sensed a presence in your room or a pressure on your chest. This is sleep paralysis. It is a common disorder that affects millions of people. Most believe it occurs as we are on the edge of REM sleep. The disorder has been connected with such hallucinogenic events such as alien abduction or an evil presence. Sleep paralysis is an inability to move or speak, occasionally accompanied by hallucinations, for up to several minutes upon awakening or just before falling asleep.
