Relationship between Sleep Habits and Personality Types

Researchers have studied the relationship between sleep habits and stress, personality and stress coping, and personality and sleep habits. One factor that has been widely overlooked is the relationship between sleep habits and personality types. The purpose of this study is to examine a relationship between personality types and sleep habits.

Evidence also shows that there is a relationship between personality and sleep. A study conducted by the director of the Sleep Assessment and Advisory Service at the University of Surrey in England, Chris Idzikowski, proclaimed that one's sleep position is related to personality.
