Body language

Body language is a way we share information without using words. We show what we feel and think through our actions. This includes facial expressions, how we hold our bodies, gestures, where we look, and how we touch or use space.

Even though we don’t always notice it, body language is a big part of how we talk to each other. It can make us feel more or less comfortable with someone. For example, in visits with doctors, a person’s body language can make patients feel more open to share their worries.

Body language is not the same as sign languages. Sign languages have their own rules, just like spoken languages. Some people think we share more through body language than words. But, it can be hard to understand because what a body language means can change depending on where someone is from or their culture. The study of body language is called kinesics.

Evolutionary origins of body language

Body language is one of the oldest ways that humans and other animals communicate without words. Animals like chimpanzees and bonobos use gestures and facial expressions they are born knowing and also learn from others. Humans do the same, using actions like raising an arm to signal the start of a game.

From a very young age, people use body language to show feelings or get attention. While humans use these signals for deeper meanings, some animals use them for quick reactions to specific situations.

Physical expressions

Body language includes facial expressions and postures that show our emotions. Facial expressions involve movements of the eyes, eyebrows, lips, nose, and cheeks. People can sometimes fake smiles, and eye contact can show interest or honesty. The way we position our heads and faces also shows feelings, such as tilting the head to show interest or nodding to agree.

Our body postures and gestures also share what we feel. Standing or sitting with open arms shows openness, while crossed arms may show impatience. Handshakes are common greetings that can build trust. How we walk, or our gait, can show if we feel happy or sad. These nonverbal cues help us understand each other without words.

Main article: Oculesics

Oculesics is about how we use our eyes to talk to each other. Eye contact and eye movement can show how we feel and help us understand one another. But what this means can be different depending on where you live. For example, in some places, not looking at someone when they talk can show respect. In other places, it might seem like you are not being honest.

We also talk through touch. A hug, a pat on the back, or holding hands can show love, friendship, or respect. Different kinds of touch mean different things — like a handshake at work or a hug between friends.

Main article: Proxemics

Proxemics is about the space we keep between people when we talk. Everyone has different comfort zones: very close for special moments, a little farther for friends and family, and even more space for people we don’t know well or when speaking to a group. These spaces can change based on where people live and what they feel comfortable with.

Tone of voice

Main article: Emotional prosody

The way we hold our bodies can change how we sound when we talk. A high voice often shows we are excited, while a low voice can sound serious. The way we say something—like if our voice goes up at the end—can tell others if we are asking a question or making a statement. How fast and how loud we speak also gives clues about our feelings. Speaking quickly and loudly might show anger, while speaking slowly and softly can sound calm and gentle.

Attitude

Body language is important in showing how someone feels. Experts say that when people talk about feelings, only about 7% of what they say comes from their words. About 38% comes from how they say it, and around 55% comes from their body language. This shows how much body language helps us understand each other.

People can change their body language to show different attitudes. This can change how others see them. Whether someone seems formal or relaxed can change how the other person reacts.

Trust

Body language that shows trust feels open and warm. Untrusting body language seems closed and cold. This can change depending on relationships.

For example, in doctor-patient relationships, open body language like relaxed posture and eye contact helps patients trust their doctors more.

In business, trust is shown in a formal way that follows business etiquette. People can show power and control through their posture, gestures, and facial expressions. This can affect sales and relationships. In friendships, body language is usually more expressive and informal, with open gestures that help friends communicate better. In close relationships like marriage, trust is shown through personal gestures, such as holding hands, which shows warmth and closeness. Couples often stand or sit closer together than people who are just colleagues, showing their bond.

Readiness

Body language can show if someone is ready to do something, like a physical activity or talk to someone. When people feel ready, their whole body can change — their voice might sound stronger, their posture might become straighter, and they might seem more energetic. This readiness can also change how their skin looks, making it appear tighter when they are more alert.

Professor Amy Cuddy once suggested that standing confidently for two minutes could boost confidence, but later studies showed this might not always work.

Universal vs. culture-specific

People have long wondered if body language, especially facial expressions, means the same thing to everyone. Some think we are born with these expressions. Others believe our culture teaches us how to show emotions.

There are two main ideas about this. One idea says that everyone can understand emotions the same way, no matter where they live. Studies show that people from very different places can still recognize basic emotions like happiness or fear. Another idea suggests that we are better at understanding people from our own culture. However, most agree that seven basic emotions — happiness, surprise, fear, anger, contempt, disgust, and sadness — are understood by everyone. Recent studies also show that feelings of pride and shame have common expressions across cultures.

Applications

Body language helps people talk to each other in many ways. Teachers use it to help students learn new languages. They use gestures and facial expressions to make the words clearer.

In games like poker, players watch each other’s actions to guess if someone is telling the truth. Some law enforcement officers also study body language to see if someone might be lying, but this is not always reliable. In comedy, big and funny body movements can make performances more entertaining.

Kinesics

Main article: Kinesics

Kinesics is the study of how we talk to each other using our bodies. It looks at how we move our arms, hands, faces, and whole body to share ideas without words. This idea was first studied by Ray Birdwhistell. He believed that gestures can mean different things depending on where and when they happen. He thought we should always think about the whole situation when we watch someone's body movements.

Sports

Body language in sports is important. It shows how athletes feel and what they plan to do, even when they don’t speak. Things like facial expressions and postures can tell us about an athlete’s feelings or how they are doing. People watching, like opponents and referees, can read these signs. This can change how they see the athlete or affect decisions in the game.
