Studies of young soldier's cognitive abilities and vigilance demonstrate deterioration after just one night of sleep loss. After three nights of sleep loss, the soldiers exhibited severe impairment and in certain cases, paranoia and hallucinations. To manage the deprivation part, we must understand what sleep represents. Sleep is a biological state that is caused by the discharge of specific neurons in certain parts of the brain. This 90 minute cycle is repeated 3 to 6 times during the night.
Sleep occupies one third of our existence.
It is necessary for our physical and mental health. Sleep affects almost every physiological and psychological process. The body has normal low cycles called circadian rhythm lows. These lows are represented by increased sleepiness. When we do not get enough sleep, our body will physically try hard to make us sleep and psychologically we crave it.
