Oftentimes, body language can be compartmentalized into "negative" or "positive," body language expert Blanca Cobb, M.S., tells mbg. When someone's body tenses up, that's a common "negative" expression, which may be related to stress, discomfort, or anger. On the other hand, "positive" body language—like relaxing the body or resting comfortably—can indicate happiness and trust.
