Body Language Cues That Signal Danger (and How to Send Your Own Safe Signals)
26. Lip Biting or Pursing

Your mouth can give away hidden emotions, even when you’re not speaking. Subconscious lip biting or pursing is a common sign of anxiety, stress, or deep thought. It can be a person's way of trying to self-soothe in a stressful situation. When a person is trying to suppress a strong emotion, such as anger or frustration, they may purse their lips. Recognizing this subtle cue can give you insight into a person's emotional state, allowing you to gauge whether a person is being genuine or holding back their true feelings.
27. Head Position and Angle

The angle of a person's head can reveal their level of interest, confidence, or defensiveness. A head tilted to the side often signals interest and engagement, as it's a vulnerable, open position that suggests they are listening. Conversely, a head lowered or tucked into the shoulders can communicate insecurity, fear, or a desire to hide. A person who holds their head high with their chin slightly raised may be signaling arrogance or dominance. By paying attention to a person's head position, you can better understand their emotional state and intentions.
