CHAPTER 1
Problem and Its Background

Introduction

Sleep is a physical and mental resting state in which a person becomes relatively

inactive and unaware of the environment. In essence, sleep is a partial detachment from the

world, where most external stimuli are blocked from the senses. Normal sleep is characterized

by a general decrease in body temperature, blood pressure, breathing rate, and most other

bodily functions. In contrast, the human brain never decreases inactivity. Studies have shown

that the brain is as active during sleep as it is when awake.

Sleep is a behavioral state that is a natural part of every individual’s life. We spend

about one-third of our lives asleep. Nonetheless, people generally know little about the

importance of this essential activity. Sleep is not just something to fill time when a person is

inactive. Sleep is a required activity, not an option. Even though the precise functions of sleep

remain a mystery, sleep is important for normal motor and cognitive function. We all recognize

and feel the need to sleep. After sleeping, we recognize changes that have occurred, as we feel

rested and more alert. Sleep actually appears to be required for survival.

Importance of the Study

Sleep can even enhance your memory. Those who regularly sleep well have better memory function than those who don’t meet the required number of hours for sleep. This means learning is also affected by sleep patterns.

Proper amounts of sleep keep your mind and body alert and it preps them to receive and learn new information. Sleeping is therefore very important for children, especially students. So those pulling all nighters to study or to finish their homework will have more difficulty in absorbing information and will not be as focused and attentive the next day.
