Contrary to popular belief, sleep is more than just a period of inactivity. While you are sleeping, cognitive mechanisms occur in your brain, facilitating memory and learning, both of which are important for task performance.
Many people tend to underestimate the value of sleep, sleeping less than needed. Being sleep deprived has several repercussions such as loss of concentration, slower response and risky decision making. It also adversely affects our emotional wellbeing, causing us to be more easily irritable or depressed.
