In this paper, I sought to uncover the ramifications that follow sleep loss and what actions are dependent on sleep to better understand its overall importance. Previous research has found that sleep deprivation can result in depressive moods, impaired decision-making, and weight gain. In my correlational study, I tested the strength of these relationships by examining naturalistic daily changes in their variables longitudinally over a two-week period. To measure the consequences that follow sleep deprivation, I monitored depressive moods, counted impaired decisions and calculated total calorie intake, and compared them to the number of hours of sleep attained. Data from this study showed a notable correlation of sleep with calorie intake but not with depressive moods nor with the ability to make decisions.
