Sleep Deprivation!

Consciousness is what we are aware of the feelings, thoughts, sensations and environments but the consciousness get alter when we sleep, take medicines, hypnosis and take drugs. Now, it comes as why we need to sleep? The simple answer is that body and mind both need to restore. There are two kinds of sleep such as non-rapid eye movement and rapid eye movement. It has been found from the research that each cycle of sleep is about 5-90 minutes. For the different age group of humans the sleep time is different as newborn child sleep almost for 20 hours and older people sleep for less than 6 hours. Even though it is know that prolonged wakefulness effects human body badly. As by the research by Patrick and Gilbert in year 1986 that the wakefulness for 90 hours continuously causes in decrease in sensory acuity, motor speed, ability to memorise, and production of visual hallucinations. This happens because of the not having the proper sleep and that is called as sleep deprivation. It might be of different kinds such as chronic and acute. There are many psychological effects on the human body and mind because of this sleep deprivation. Total and partial deprivation effects human bond and mind in different ways such as it disturbs the concentration, learning and mood. The brain activity also changes in wrong side and doesn’t work effectively. Till today there has not been such kind of neurological study on sleep deprived individuals. Awakening for a long time will surely affect the human body and will cause the number of sleep disorders such as Parasomnias where the awake take place while sleeping like sleepwalking or sleep talking, dyssomnia where timing, quality and quantity of sleep is impaired.

While sleeping human dream too and that is of different kinds like REM, NREM and Lucid dreams that depends on the dreamer while sleeping and the kind of sleep too. For example, let’s take an example as in year 1964 a 17 years old boy at Navy Medical Neuropsychiatric Research Centre in Unites States Naval Hospital at San Diego California who didn’t sleep for 264 hours continuously and that caused several problems to his body, mind and vision. This patient was closely observed by Dr. William Dement. According to Dr. William Dement on first day the boy was okay as he was feeling refreshing but on second day the boy found that the vision of the boy was diminishing and he was getting difficulty in opening his eyes correctly while he was trying to watch a movie and then next day it was found that the boy was not able watch the television properly. Slowly, on next day he found that his mood changed and his tongue was also seemed as twisters. On fourth day the body found significant changes as memory lapse, difficulty in concentrating on the things, feeling of a tight band around his head, and his vision was like that he was observing the fog in the street. On fifth day, the boy’s equilibrium was balance but he caught with intermittent hypnogogic reveries. Slowly, the blurred vision of the boy for next few days got in to more problem. For the last 2 days, anything he was hearing seem like foolish to him as he was not able to memorise the things he heard on the first day.   After this the patient finally went for a sleep and slept for more than 14 hours continuously.

This example signifies about the sleep deprivation and its effects on the body and mind of the people who don’t take proper sleep. The healthy boy whose initial blood pressure was 120/180 Hg, pulse rate was 72 and temperature was 36.1 C got significant changes. Even though during the awaking the pupils of the boy reacted normally but there seemed some significant movements in his body and mind with the time of awakening. Sleep deprivation causes number of harmful things to the human body and sometime causes the fatal diseases too if the sleep deprivation goes on continuous. In this sleep deprivation initially, there is abnormal behaviour happens but after some time it goes normal after some days. The most important body part that affected much is eye and mind. Sleep deprivation increases the psychiatric difficulties in the body and it take long time to recover than sleep deprivation is occurs. Because of this the life style and body thinking goes change and sometime things seem as not perfect because of the lack of concentration, mood change and memory lapse. Physical and mental conditions get change with the time if sleep deprivation goes for longer time and no proper meditation is done. Mediations improve the consciousness of the body and allow thinking on focused objects. In the above example the sleep deprivation for a long time may lose the concentration and memory strength and that can be achieved through the meditation. Mediation is very important in case of having the sleep deprivation because it reduces the blood pressure and controls the human emotions.

People use some drugs to control the sleep deprivation like hypnosis that controls the pain of the body and helps in power suggestion in thinking, feelings and sensations. The humans who take the drug occasionally and frequently also get in to the sleep deprivation problem because the drugs affect the human brain thoroughly and speed up the activity in the central nervous system. It also changes the behaviour relatively and stimulates the organism. Conditioning response of the body become weak. In the 17 years boy example, it was observed that the behaviour of the boy got change after the sleep deprivation for 264 hours and it causes the number of changes in the boy’s mental and physical activities for a long time. These changes get reverse in normal conditions after a 6 -8 months of proper mediation and care of the boy. Thus, the final outcome is that sleep deprivation is not good for human body and mind.
