Circadian rhythm sleep disorder

Before we explain what Circadian Rhythm Sleep Disorder (CRSD) we need to define circadian rhythm. Our bodies function according to a cycle, a sort of biological clock, located in the part of the brain part of the called the hypothalamus. The circadian rhythms are regular changes in mental and physical characteristics that occur in the course of a day (circadian is Latin for "around a day"). Light causes signals to be sent to several regions of the brain which causes the body to switch on and off the production of hormones. These cycles are synchronized with the sleep / wake cycle. When we are deprived by light or some other external time cues, most of us suffer an affect to our internal clock. The circadian rhythms can be affected to some degree by almost any kind of external time cue, such as your alarm clock, the timing of your meals, etc. Circadian Rhythm Sleep Disorders (CRSD) can be categorized in five distinct types; Jet Lag, Shift Work Related…

According to American academy of sleep medicine (American academy of sleep medicine, 2010), circadian rhythm sleep disorders (CRSD) results from timing when a person is awake and when sleeps. Humans have an internal clocks in the brain called suprachiasmatic nucleus (SCN), where primary circadian rhythm help control the body sleep-wake cycle. This circadian clock is set by visual stimulation using light and darkness using the eyes and guides. Some examples of circadian rhythm sleep disorders…

“Every living thing on the surface of the planet has a system to synchronize [itself] with day and night” (Barone 8). Sleep is a natural part of life and most people, at some point in their life, experiences difficulty sleeping. Today, however, sleep disruption is becoming a more prominent issue due to the rising number of electronic devices. Because of the blue light illuminance these devices produce, the brain’s secretion of the sleep-inducing chemical melatonin is disrupted; therefore,…

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 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…

experienced days where we are running on fumes. We function to the best of our ability and look forward to returning to our beds for needed slumber. According to an article presented by the National Sleep Foundation, “How much sleep do we really need?” adults between the ages 18 to 64 are recommended 7 to 9 hours of quality sleep. Unfortunately, 1/3 of Americans are sleeping less than 7 hours on a nightly basis. This continuation of sleep debt is taking its toll on our nation and has gradually…

Does your child seem to get a lot of homework? This seems to be a problem affecting many students in our world. Today, many students seem to have so much homework. The effects of too much homework are as follows: disturbance of the life balance of the child, less time for friends, family, and extracurricular activities, and greater amounts of stress. For these reasons, the amount of homework a child receives must be reduced. To begin with, too much homework disturbs the life balance of the…

possible… . Saying ‘I’m tired and I’m going to sleep’ is viewed as being lazy.” Sleep research Dr. Eve Van Cauter (Brody) provided this adequate description of how our high demand, 24 hours a day, seven days a week world, is robbing substantial numbers of people of sleep. For many Americans “inadequate sleep is a workaholic’s badge of honor” (Brink). We proudly pin on our badge of sleep deprivation and polish it brightly for others to see our dedication and hard work. However, advancements…

considerations. But what millions of people in North America have a serious problem with, is the ability to not get proper sleep and most don’t realize how detrimental that affects ones health. This could be a result of a lack of educated information such as what amount of hours a sleep the human body should obtain, or these individuals aren’t aware of their bodies are telling them. There are many studies that take a look at sleep disturbances in the general population, results show that sleep…

Is it because the lack of sleep which causes sleep deprivation or because the mind needs ample time to recharge Is it because, effects of sleep deprivation between shifts depending on whether they have adjusted to the shift over time? Is it because sleeping too little or sleeping “against” your body’s natural biological clock could increase the likelihood of developing diabetes or becoming obese or other health issues? There are millions of shift workers in the U.S. include police officers,…
