The mechanics of a hug vary based on the relationship and the context. Some hugs are brief, lasting only a single second as a quick squeeze. Other hugs involve an extended period of holding each other closely. In some cases involving lovers, the participants may also press their hips together. The direction of the hug often follows a person's handedness. Right-handed people typically lead with their right hand. However, a heightened emotional state can cause a person to lead with their left hand. This shift is often linked to right-hemispheric emotional processing in the brain.
