Natural Darkness

People require seven to nine hours of sleep to recuperate from physical exertion. The
need for sleep is also used to consolidate learning and memory. Sleep is necessary for proper
physiological and psychological functioning of a human being. People who work for long
periods without rest risk losing their immune function and prolonged period without sleep will
cause death. In the developed world, most people tend to work day and night without sleep,
which causes serious health consequences (Bogard, 2013). The health risks are heart disease and
obesity, among other conditions. When people sleep, they engage in dreams that may serve
different roles in their health. The dreams serve as a therapist since they confront emotional
dramas in our life. The dreams also act as memory aides since they help individuals store
essential memories and issues learned in our life, get away with unimportant memories.
One of my friends supported that sleep and dreams both help in storing memories. He
argued that when he is awake, he can learn different things, and during sleep, he begins to recall
it better and memorize the knowledge gained. There are occasions in which he has some vivid
dreams. When he eats high-carbohydrate food and gets enough energy, such food consumption
leads him to have vivid dreams.
