(Holloway, 2013) 2. Sleep deprivation affects the body as a whole....

occur when a person has a significant sleep deprivation. The brain automatically shuts down, falling into a sleep state for a period that can last from a second to half a minute. The person falls asleep no matter what activity he or she is engaged in. Microsleeps are similar to and a person experiencing them is not consciously aware that they are occurring.

One possible reason for the many problems sleep deprivation causes today is the extent to which modern Western society ignores the importance of circadian rhythms, the daily sleep-wake cycles that are controlled by a combination of physiological and environmental factors, but certainly not by the force of will. In earlier times and in primitive societies, in other words, for the majority of human history, these cycles were synchronized with day-night cycles. In modern times, most of us synchronize our sleep periods with the clock instead, staying up well into the night as well as waking before sunrise. If synchronization with an external sign (the clock or the sun) was all that were involved, the process would be fairly easy and problem-free. Unfortunately, we also have an internal, biological clock to contend with, which evolved over hundreds of thousands of years of human experience before alarm clocks, graveyard shifts, and jet lag came along. When people are removed from the influence of external cues, perhaps by being placed in a windowless laboratory with no clocks or watches for several weeks, they continue to follow a steady sleep-wake cycle, but oddly enough, it is a twenty-five-hour cycle rather than a twenty-four-hour cycle, in which they fall asleep 1 hour later each night. The external cue (the sun) is used by the brain to reset its clock each day, and in its absence, the clock gets further and further off.

He went into detail about lucid dreams, and how it improves a person’s sleep.

But what causes sleep deprivation.

Unfortunately, those few hours could have prevented sleep deprivation.

A survey found that college/university-aged students get an average of 6.7 hours of sleep each night.[] Sleep deprivation is common in first year college students as they adjust to the stress and social activities of college life. A study performed by the Department of Psychology at the in Taiwan concluded that freshmen received the shortest amount of sleep during the week. In 1997 the did research that compared students who went to school at 7:15 a.m. and those who went to school at 8:40 a.m. They found that students who went to school at 8:40 got higher grades and more sleep on weekday nights. One in four U.S. high school students admits to falling asleep in class at least once a week. It is known that during human adolescence, and therefore sleep patterns typically undergo marked changes. Electroencephalogram (EEG) studies indicate a 50% reduction of deep (stage 4) sleep and a 75% reduction in the peak amplitude of delta waves during NREM sleep in adolescence. School schedules are often incompatible with a corresponding delay in sleep offset, leading to a less than optimal amount of sleep for the majority of adolescents.

The specific causal relationships between sleep loss and effects on psychiatric disorders have been most extensively studied in patients with mood disorders. Shifts into mania in bipolar patients are often preceded by periods of , and sleep deprivation has been shown to induce a manic state in susceptible individuals. Sleep deprivation may represent a final common pathway in the genesis of mania, and sleep loss is both a precipitating and reinforcing factor for the manic state.

Let’s explore the exhausted world of sleep deprivation.

Sleep deprivation can sometimes be self-imposed due to a lack of desire to sleep and/or the habitual use of stimulant drugs (i.e. Cocaine, Amphetamines, etc.) Recent studies have also suggested that sleep deprivation produces similar effects in the brain to that of an SSRI in persons with depression, thus ensuing a clinical, self-imposed remedy. However, most individuals suffering from clinical depression are not aware that lack of sleep is having a direct positive effect on thinking. Sleep deprivation is also self imposed to achieve personal notoriety in the context of . Voluntary sleep deprivation is also utilized in the converting from monophasic sleep to .

Sleep deprivation affects one’s school performance and one’s health too.
