The Importance.. Sleep has been linked to psychological, emotional, and mental recovery, as well as learning and memory. Research shows that sleep is vital in consolidating memories, both intellectual and physical. Sleep deprivation can inhibit your productivity and ability to remember and consolidate information. It can also lead to serious health consequences such as increased risk of heart disease and obesity.

How much sleep do you need? The amount of sleep we need varies depending on age, physical condition, psychological condition, or energy exerted. Sleep patterns can be genetically and culturally influenced. Some people thrive with fewer than 6 hours of sleep per night and others regularly sleep 9 hours or more. People in industrialized nations sleep less than they did a century ago.
