A new study found that sleeping positions affect personality by determining how we feel when we wake up. People who sleep on their backs with arms stretched out in front typically wake up feeling refreshed and eager to start their day. Sleeping face down with arms outstretched indicates a feeling of being “out of control” and leaves these people feeling tired with no energy. Those who sleep with a straight body are stubborn, and will feel stiff in the morning. And the most popular sleeping style? The fetal position. 58 percent of people sleep on their side with their knees up and head down– which is no surprise considering it is associated with stress.  These people can expect to awake refreshed, having dealt with the previous days issues. I’m pretty sure I hit all of those positions at some point throughout the night. What does that say about me?
