The four types of body language are:1. Facial expressions:Facial expressions can convey a wide range of emotions, from happiness and excitement to anger and sadness. They can also be used to communicate non-verbal cues, such as when someone is interested in what you’re saying or when they’re not.2. Eye contact:Eye contact is an important form of body language that can be used to convey a range of emotions, from interest and attraction to anger and hostility. It can also be used to communicate non-verbal cues, such as when someone wants to listen to you or when they want you to stop talking.3. Posture:Posture can convey a lot about a person’s emotional state. For example, someone who is slouched over may be feeling sad or defeated, while someone who is standing up straight may be feeling confident and powerful. Posture can also be used to communicate non-verbal cues, such as when someone is open to talking or when they want to appear more approachable.4. Gestures:Gestures are another form of body language that can be used to communicate a range of emotions, from happiness and excitement to anger and frustration. They can also be used to communicate non-verbal cues, such as when someone is emphasizing a point or when they want you to come closer.
