Body Language at Work: What You "Say" Without Speaking
How body language at work affects credibility, which habits help and which to avoid, how to read others' signals with care, and how to practise naturally.
You prepared everything for an important meeting, but throughout the presentation you looked down at your notes, spoke quietly and held your folder tightly against your chest. Afterwards your manager says, "Good data, but you didn't seem very confident." Everything you said was correct, but what your body communicated made people hesitate. That is the power of body language that many people overlook.
What is body language, and how much does it matter?
Body language is communication through posture, facial expression, eye contact, distance and tone of voice, without words. Many people have heard the figures "7% words, 38% tone, 55% body language" from Albert Mehrabian's research. But Big Think explains that these numbers come from lab experiments that studied only the communication of feelings and attitudes, and Mehrabian himself said the equations do not apply unless someone is talking about feelings. A more accurate takeaway is that words still matter a lot, but when body language contradicts words, listeners tend to believe what they see.
Body language that helps you look confident and trustworthy
Eye contact
Look at the person you are talking to naturally and regularly, without staring the whole time. In Thai culture, holding eye contact with a senior person for too long can seem impolite, so alternate between their face and your documents.
Standing and sitting
Back straight, shoulders relaxed, feet planted. In meetings, sit fully in your chair and lean slightly forward when others speak to show you are listening.
Using your hands
Open hand gestures that match what you are saying help emphasise your points, such as counting on your fingers when you list three items. Avoid waving so much that it distracts from your content.
Facial expression and smiling
Smile when greeting people and when talking about good news. When discussing serious topics, such as problems or bad news, your expression should match the content.
Habits to avoid
- Crossing your arms while talking: it can look closed or disagreeing, even if you are just cold.
- Looking at your phone in meetings: it signals that something else matters more than the people in front of you.
- Constant fidgeting: bouncing your leg, spinning a pen or touching your hair makes you look anxious.
- Slouching or leaning back heavily: in formal meetings it can look like you are not taking things seriously.
Read other people's body language with care
Signals like nodding, leaning forward or asking follow-up questions usually mean interest. Checking the time, giving shorter answers or turning toward the door may mean they want to wrap up. But never interpret a single gesture. Crossed arms may just mean cold, avoiding eye contact may just mean shy. Look at several signals together, and if unsure, ask directly, for example, "Is there anything here you would like me to explain further?"
Example: body language in online meetings
On a video call people see only your face and shoulders. Put the camera at eye level with light in front of you, look into the camera when making key points, nod visibly when listening, and turn off notifications so your eyes do not drift to other screens.

Body language in Thai workplaces
- Wai and greetings: give a natural wai to senior people or clients where appropriate. Handshakes are more common with foreign clients or in international settings. If unsure, follow the other person's lead.
- Distance: stand far enough away for the other person to feel comfortable, especially with people you have just met.
- Tone of voice: speak clearly and not too fast. Thai politeness does not require speaking so softly that people cannot hear you.
- Disagreeing with seniors: a calm, open posture and a gentle tone help disagreement sound constructive rather than challenging.
Your body starts communicating before you say your first word. Make sure it says the same thing as your mouth.
Where to start: practising natural body language
- Record yourself rehearsing a short presentation, then watch it on mute and notice what your gestures communicate.
- Change one thing at a time, for example no crossed arms this week and eye contact next week.
- Ask for feedback from a colleague you trust after important meetings.
- Know your content well, because confidence in the material relaxes your body naturally.
- Practise interviews with Interview Lab until your answers feel natural.
