    Reznik: Dissociated Personality

    Science has proven that sleep is one of the most essential things needed to keep the average individual healthy and stable. Without the “healing” powers of sleep, our minds and our bodies can be easily affected because of the constant feeling of fatigue. The human body thrives on the energy that sleep ensues in our bodies every night. While the average individual is to sleep approximately eight hours a night, realistically speaking, getting that much sleep on a regular basis is something to strive for. And while the amount of sleep we get per night might waver around the average, sleep deprivation is a far cry from being sluggish the next morning. Sleep deprivation has an extreme affect of the mind and body because of the lack of energy that your body may have stored up. However, the biggest affect it might have on your body is the brain. It has been proven the lack of…

In discussing regulatory process, sleep is perhaps one of the most essential to the healthy upkeep of the human nervous system. This process is such a necessary behavior that without it, the nervous system, and the overall health of the individual in question can become compromised (to the point of fatality) without it.…

    Furthermore, according to previous findings, sleep alterations can favor the development of depressive mood disorder. This survey aimed to assess the prevalence and characteristics of sleep disorders in a young population sample and their association with depressive symptoms. With a cross sectional study design, self-administered questionnaires were applied to 1,180 undergraduate students. The Questionnaire and the Beck Depression Inventory were used to evaluate sleep disturbances and depressive symptoms. Sleep alterations are prevalent complaints among young people, being present in nearly 60% of the students.
