Sleep Deprivation essay

What are the physical effects of sleep deprivation?  According to nature sleep is part of life for human beings which must be satisfied without which there will be reduced effects on an individual. This essay will focus on experiments that have been done on sleep deprivation and its effects on human beings in order to answer the question appropriately. A lot of articles and research has been done on the effects of sleep and we shall dwell mainly on those that are physically exposed rather than those that cannot be manifested. The essay focuses on answering the question on the physical effects of sleep deprivation as it applies across normal human beings.

Sleep deprivation is the process where sleep is removed from an individual. This cannot be fully achieved because there has been no advanced technology which can fully do away with sleep and as a result there will be some “micro-sleeps” which cannot be ruled out. This is because lack of sleep will accumulate to a point where one cannot be in a position to control the debt accumulated. The consequence of sleep deprivation which cannot be avoided is “micro-sleeps” that may overcome an individual. However, sometimes an individual can be deprived sleep out of sickness which is inevitable (Kushida, 1 & 2).

According to Myco (1983), sleep deprivation affect the process of tissue renewal in the body. This means that the normal body process is interfered because there is no time for proteins to be converted to repair worn out tissues. As a result the tissues become worn out and body weakness sets on the individual. He further argued that an individual deprived sleep will have fluctuating performance during the daily activities. There will be a sense of tiredness in which an individual have an urge to rest and withdraw from normal activities. The person will be fighting off the pressure to quit work and just relax.

Additional effect of deprived sleep as indicated by Myco (1983) is the impaired concentration. This is a process where the brain is too tired to synchronize directions and occurrence. The attention towards the surrounding is greatly reduced when one is deprived of sleep and may further lead to failures if not accidents in the day to day activities. Moreover, there would be halt of movement by the patient as they prefer to be stationary at one point. The failure of movement will make an individual deprived of pleasure to enjoy the natural environment (Myco 161).

In addition, the patient will start complaining of discomfort and physical symptoms of ailments like headache and muscle strain. This will make patient weak and appear to struggle because the important tissue repair done when an individual is a sleep has failed to take place. Thus complications will arise out of deprived sleep causing drowsiness and even situations where visual perception will be impaired as the patient will see unclear objects (Myco, 161).

Myco (1983) states further that the effects of deprived sleep is not actually sickness but rather complaints. They do not need any treatment but only to sleep and their complaints will be gone. The body muscles need to be totally relaxed and allow the nervous system to work on its repair and maintaining total level of activity which brings back the normal body functioning. The fact that sleep deprives an individual an opportunity to be refreshed, the feeling of fatigue will be continuous as confirmed by brain-wave behavior, the heart rate and reduced temperature readings (Myco, 162).

Experiments carried out on sleep deprivation continued to indicate its effects according to Aldrich (1999). The earlier signs were trouble in focus as an individual could no longer view a television on the second day. The explanation continues to confirm the failure of body movement and deteriorating speech on the third day. The experiment went on and there was a memory lapse coupled with lack of attention and own imaginations on the fourth day. At this point there was fall in temperature to low standards. The continued complications reached their all time higher to the extent that the patient could virtually complete a sentence and had become totally confused. This experiment shows the extent at which deprived sleep causes body disorganization to the extent of being totally disoriented (Aldrich 118).

Aldrich (1999) further brought out the effects of deprived sleep being manifested on daytime sleepiness which happens frequently in the afternoon and early evenings. The confusion state is pronounced on an individual deprived of sleep for some days. The performance is affected mainly because there is a disorganized way of attending to work and sometimes not responding at all due to lack of any motivation. The nature of work being done will also determine the degree of performance because some jobs like playing video battle games may require less concentration. Thus those jobs that require a lot of skill and concentration will not be done by persons deprived of sleep because their brains are in a state of disorientation (Aldrich 119).

The blurred vision and thinking problems increases with the increase in time of deprived sleep. The brain will undergo perceptions which may not be connected making one not to understand what they are being told. The mind will be in a dream state intrusions and fantasies which slow normal thinking and causes problems in maintaining the flow of words and thoughts (Aldrich, 119). However, the effects of deprived sleep do not affect other functioning of the body parts meaning that the effects are concentrated in the brain.

Another research on deprived sleep indicated similar effects of underperformance and dizziness. The experiment noted that activities that suffered impairment are those that require involvement of the brain on reasoning, deciding and reacting within a short time (Andreassi, 135). This experiment still points to the importance of sleep to normal functioning of the brain.

Due to the consistent effects of deprived sleep on the brain, it becomes apparent that for a normal functioning of human mind sleep is a necessity. Sleep ensures that crucial rest is achieved for the brain functioning. The sleep deprivation affects people of different ages differently. The youth are more affected by sleep deprivation more than the older (Andreassi, 136). Thus the young people require more sleep than those of older age because they are very active and their brains need more rest.

Therefore in general it can be considered that sleep deprivation can disrupt short-term memory in a normal human being (Andreassi, 138). Moreover, lack of sleep causes serious effects on performance and discomfort. The recovery is achieved when a person sleeps and the normal body recovery continues.


There has been continued research on the effects of deprived sleep and with advance of technology more analysis is given. The effects of lack of sleep have been proved by several experiments as indicated above and all continue to support the fact about affected performance on individuals. However, the conclusion in our case is that there is direct relation between deprived sleep and the performance of an individual thus making sleep a necessity for normal operation of all human beings.
