Facial expression
Facial expression is integral when expressing emotions through the body. Combinations of eyes, eyebrow, lips, nose, and cheek movements help form different moods of an individual (e.g. happy, sad, depressed, angry, etc.).
Body postures
Emotions can also be detected through body postures.
Gestures
Gestures are movements made with body parts (e.g. hands, arms, fingers, head, legs) and they may be voluntary or involuntary. Arm gestures can be interpreted in several ways. In a discussion, when one stands, sits or even walks with folded arms, this is normally not a welcoming gesture. It could mean that they have a closed mind and are most likely unwilling to listen to the speaker’s viewpoint. Another type of arm gesture also includes an arm crossed over the other, demonstrating insecurity and a lack of confidence.
Handshakes are regular greeting rituals and are commonly done on meeting, greeting, offering congratulations or after the completion of an agreement. They usually indicate the level of confidence and emotion level in people.
Body language related to breathing and patterns of breathing can be indicative of a person's mood and state of mind; due to this, the relationship between body language and breathing is often considered in contexts such as business meetings and presentations. Generally, deeper breathing which utilises the diaphragm and abdomen more is interpreted as conveying a relaxed and confident impression; by contrast, shallow, excessively rapid breathing is often interpreted as conveying a more nervous or anxious impression.
