Hugging one’s self is a defensive and closed body position. The arms will hug the body tightly in a full embrace.

A variation of this posture happens by reaching across the body and grabbing the opposite shoulder. While the double arm huge is a defensive postures, the partial arm cross is a subtle posture that indicates fear, timidity, shyness and lack of self confidence. Both are barrier type postures which protect the core of the body like a shield. It signals to others that we don’t wish for them to come close.

The posture feels natural and comfortable when in fearful situations because it reminds us of the sensation of being hugged and protected by someone else.
