When you cross your arms and legs, you are exhibiting defensiveness—even if your reason is cold weather! If you keep your head down and avoid eye contact, you send a message that you are avoiding interaction—even if your reason is shyness and you actually want someone to talk to you! People generally respond to these signals by ignoring you; you are not considered approachable. If you rest your chin in your hand, it appears that you are bored. Likewise, when you place your hands on your hips, you appear aggressive and unhappy with your conversation partner, or with the words you are hearing.
