What Is Hypoxia?

Hallucination: This is a perception of a sensory experience without external stimuli. It may be visual, auditory,

B. Hallucinations, are perceived through one of the senses and do not correspond to any stimulus in the outside world. Hallucinations are defined as perceptions in a conscious mind.

In a laboratory study of sleep deprivation, researchers employed a variety of techniques to keep

* Hallucinations – see things that aren’t there or talk to people who aren’t around.

Why these sensory deprived individuals shut down mentally is explained in an article by the University of Indiana. “Not only do sensory inputs keep us from getting bored, they also keep our brains functioning within healthy parameters. Should we lose access to natural light, social interaction and physical touch, we quickly begin to unravel. Surprisingly, research shows that even 15 minutes of near-total sensory deprivation can cause hallucinations on par with psychedelics. (University, 2011)”

A hallucination is an experience involving the apparent perception of something not present. In Macbeth, Shakespeare uses hallucinations to show the feeling of guilt, the amount of hallucinations someone has shows how much guilt they are feeling at that particular moment about the actions they have done. Shakespeare uses the character Macbeth and Lady Macbeth to build towards hallucination as a motif. He built towards the motif by giving the two characters hallucinations based on their past actions. In the play Macbeth, William Shakespeare uses hallucinations as a motif not only to show Macbeth and Lady Macbeth's tragic downfall, but also as a symbol of the destruction Macbeth causes within the country of Scotland.

The effects of long work hours, resulting in insufficient sleep have been well documented (Rogers, 2008). Insufficient sleep alone has been noted to cause cognitive problems, mood alterations, reduced job performance, reduced motivation, increased safety risks, and physiological changes (Rogers, 2008). Failure to obtain a sufficient amount of sleep is even an important contributor to medical errors (Rogers, 2008). Now think of the effects of sleep, and add in stressful work environments, short-staffing, pressure from administration, and unexpected events, we can begin to realize how patient outcomes may be greatly compromised.

Moreover, a hallucination is not receptive to control by the individual who is experiencing it. Auditory hallucinations are among the most common. Individuals who suffer from auditory hallucinations hear sounds or voices that have no actual source (5th ed.; DSM-5). It is common that the individual initially experience the sound as coming through his or her ears. However, sometimes, the individual will eventually perceive the sound as coming from inside his or her head (Romme et al., 1992). David and Nayani (1996) claimed that individuals who suffer from auditory hallucinations may hear more than one voice. The voices can differ in content, comment on the individual’s thoughts and even have a conversation.

These hallucinations are experienced identically to normal seeing, however they are distinguishable from reality because of their content and the fact that they often appear in clearer and greater detail than Charles Bonnet patients (whose visions have been impaired or lost) would naturally see (3). These "release" hallucinations are often not reported to doctors and psychologists because the individuals experiencing them are aware that what they are seeing are hallucinations and are afraid of being judged as crazy by those people that they might tell (5).

It is much more difficult to sleep at higher altitudes. This problem lessens with time, and it is caused by lowered oxygen levels.

Many disorders and diseases can result from abnormal sleeping patterns that are triggered from sleep deprivation. The most common forms of sleep disorders include insomnia, sleep apnea, restless legs syndrome, and narcolepsy (NINDS 10). All of these sleep disorders begin from sleep deprivation and can be managed once they are diagnosed correctly. According to Urban, “Nervousness, dizziness, and sleeplessness may occur”, as a result of sleep deprivation (1). This proves that the slightest health changes can occur if sleep deprivation becomes a problem. According to NINDS, “The disorders and the resulting sleep deprivation interfere with work, driving, and social activities” (10). This shows that the effects of being sleep deprived can drastically change one’s everyday

What do the effects of sleep deprivation have on people? When a person does not get enough sleep, he or she is depriving his or her body of something that it needs. A delightful sleep is one of the most satisfying human experiences with a role to play in supporting a good mood and cognitive acuity as well as in promoting physiologic balance and resilience (Chittora, Jain and Suhalka). People think because they get an insufficient number of hours of sleep, they will not have an emotional impact by it. Sleep is a required need for peoples’ day to day life to be able to perform and stay healthy emotionally and physically. The effects of sleep deprivation are an issue because it affects mood, performance, and health.

While "quiet" sleep, a person proceeds through four stages of increasingly deep sleep. Body temperature decreases, muscles relax, and heart rate and breathing slow down. The longest stage of quiet sleep affects physiological changes that help support immune system functioning. The other sleep level, REM (rapid eye movement) sleep, is the stage at people dream. Body temperature, blood pressure, heart rate, and breathing increase to levels estimated during people are attentive. Studies detail that REM sleep enhances learning and memory, and offers to emotional
