All living organisms maintain a complex dynamic equilibrium‚ or homeostasis‚ which is constantly challenged by internal or external adverse effects‚ termed stressors.[4‚5] Thus‚ stress is defined as a state in which homeostasis is actually threatened or perceived to be so; homeostasis is re-established by a complex repertoire of behavioral and physiological adaptive responses of the organism Our biological stress response was designed for survival and is regulated by both the neural and endocrine

is essential to the body and its functions‚ promoting bodily rest and rejuvenation in the neurons and other cells that are replaced or repaired during times of sleep. Sleep has been proposed to conserve energy‚ detoxify the brain‚ and control thermoregulation within the brain ( Maquet 2001). Ultimately‚ since sleep is so essential to the human body‚ scientist recommend approximately eight hours of sleep a night to promote efficient performance and thinking. On the other hand‚ within this fast paced
