  • Avoiding eye contact can make you appear dishonest or insecure, negatively impacting trust.
  • A weak or overly firm handshake can send unintended messages about confidence and dominance.
  • Crossing arms signals defensiveness and can create barriers in communication.
  • Lack of facial expressions can make you seem uninterested or unapproachable in conversations.
  • Research shows that body language influences both how others perceive us and how we feel about ourselves.

Body Language Mistakes: Are You Making These Errors?

Body language is a critical aspect of human communication, often conveying more than words alone. From job interviews to casual conversations, small non-verbal cues can shape how people perceive us. Unfortunately, many individuals unknowingly make body language mistakes that create negative impressions. By becoming aware of these errors and addressing them, you can improve your non-verbal communication and make a stronger impact in both personal and professional interactions.

Avoiding Eye Contact

Eye contact plays a crucial role in communication, helping to establish trust and confidence. A lack of eye contact can make you come across as nervous, dishonest, or disengaged. A study by Robbins & Kiser (2021) found that individuals who avoid eye contact are often perceived as less trustworthy and more socially anxious.

How to Improve Eye Contact:

  • Maintain eye contact for about 3-5 seconds before briefly looking away.
  • Utilize the triangle method, alternating your gaze between the person’s eyes and mouth for a more natural interaction.
  • In group conversations, shift your eye contact among individuals to include everyone.

Too much eye contact, however, can feel intimidating. A balance between attentive engagement and natural glances is key.

Weak or Overly Firm Handshakes

A handshake is often the first physical interaction you have with someone, and it sets the tone for an interaction. A limp handshake can suggest insecurity, lack of confidence, or disinterest, while an overly firm grip can feel overly aggressive or commanding. A study in the Journal of Nonverbal Behavior (Chapman & Anderson, 2022) highlights the importance of a firm yet approachable handshake for making a positive first impression.

Fix Your Handshake:

  • Use a firm, but not overpowering, grip.
  • Make eye contact and smile for added warmth.
  • Keep the handshake brief—2-3 seconds is typically appropriate.

Your handshake should indicate confidence and approachability—not dominance or passivity.

Crossing Arms or Legs

Crossed arms or legs are often interpreted as defensiveness, discomfort, or disinterest in a conversation. Whether you realize it or not, this closed-off posture creates an unapproachable and uninterested appearance. Briñol & Petty (2019) have shown that open postures increase trust and engagement in communication.

Better Posture Choices:

  • Keep arms relaxed at your sides or rested lightly on a surface.
  • Maintain an open chest posture, which conveys warmth and confidence.
  • When seated, avoid tightly crossed legs; opt for a more open, natural sitting position.

Instead of crossing your body, engage with slight gestures or shifts to show attentiveness.

Fidgeting and Nervous Movements

Frequent fidgeting—tapping fingers, shifting weight, playing with objects—signals anxiety, impatience, or distraction. While some people fidget unconsciously, excessive movements can undermine your credibility and composure. Research in neuroscience indicates that individuals who remain physically still during conversations are perceived as more authoritative and confident.

Reduce Fidgeting:

  • Clasp your hands together lightly or rest them on your lap.
  • Practice deep breathing to calm nervous energy before social interactions.
  • Improve self-awareness through mindfulness exercises to recognize and control unconscious habits.

Being mindful of your restless habits can prevent them from distracting from your communication.

Poor Posture and Slouching

Your posture influences others’ perception of your confidence and leadership abilities. Slouching signals low energy or insecurity, which can affect how seriously people take you. In contrast, upright posture enhances both self-confidence and authority. Carney et al. (2010) found that “power posing” can even increase neuroendocrine activity, improving self-assuredness.

Improve Your Posture:

  • Keep shoulders relaxed but upright—avoid tensing or hunching forward.
  • Stand and sit with even weight distribution for stability.
  • Before important interactions, engage in power posing (e.g., standing tall with hands on your hips) to boost your confidence levels.

Strong posture isn’t just about appearances—it influences how you feel as well.

Lack of Facial Expressions

Facial expressions play a vital role in conveying engagement and emotion. A neutral or stiff face can make you seem distant, uninterested, or unemotional, which reduces the effectiveness of your message. Expressiveness is essential to building rapport and demonstrating empathy.

Express Yourself Naturally:

  • Smile slightly when appropriate to appear friendly and approachable.
  • Use eyebrow movements and slight nods to emphasize points.
  • Mirror the other person’s emotions subtly to create a natural connection.

While exaggeration can seem forced, subtle and genuine expressions improve relatability.


Person nodding excessively during conversation

Excessive Nodding or Agreeing

Nodding occasionally shows engagement, but excessive nodding can indicate submissiveness or insecurity. If you nod too much, you might seem overly eager to please rather than genuinely engaged.

Proper Nodding Techniques:

  • Nod occasionally to acknowledge key points rather than constantly.
  • Combine nodding with brief verbal affirmations such as “I see” or “That makes sense.”
  • Keep your nodding slow and natural to avoid appearing overly enthusiastic or insincere.

Strategic nodding ensures you appear engaged without seeming overly deferential.

The Neuroscience of Body Language

Body language is deeply rooted in how the brain processes social interactions. Research suggests that the amygdala, the brain region responsible for emotion, responds immediately to facial expressions and posture. This means that others subconsciously judge your trustworthiness, confidence, and likability before you even speak.

Positive body language—such as strong posture and direct eye contact—can stimulate neural pathways that enhance interpersonal trust. By mastering the right signals, you not only improve how others perceive you but also how you feel about yourself.

Tips to Improve Non-Verbal Communication

Beyond avoiding common mistakes, here are some key body language tips to actively improve your non-verbal communication:

  • Increase Self-Awareness: Review your own body language by recording yourself in conversations.
  • Practice Mindfulness: Being fully present in interactions can help minimize nervous habits.
  • Use Mirroring Techniques: Subtly mimic the body language of the person you’re talking to for stronger rapport.
  • Control Your Gestures: Purposeful hand movements emphasize points effectively without looking exaggerated.
  • Be Conscious of Your Presence: Whether walking into a room or sitting in a meeting, maintain open and confident posture.

Mastering body language takes practice, but even small adjustments can create a significant impact. By avoiding these common mistakes and refining your non-verbal communication, you can boost confidence, enhance social connections, and leave lasting positive impressions in both personal and professional settings.
