What Does Your Body Language Say About You?

We often think body language is simply a reflection of how we feel—something others notice but we don’t consciously control. But our non-verbal behavior does far more than signal confidence or nerves to the outside world.

It also shapes our internal experience: how we think, how we act, and even how we feel about ourselves.

Think about someone who stands tall with their chest open, shoulders relaxed, and arms uncrossed. It’s easy to assume that that person is confident, powerful, and ready to take on the world.

Now picture someone with a collapsed posture—arms and legs crossed, shoulders curled inward, and minimal eye contact. We read weakness or insecurity instantly.

What’s fascinating is that when we feel small or powerless, our posture naturally shifts this way. And that shift can influence how actively we participate in school, social events, work, or hobbies. In other words, posture doesn’t just reflect our emotions—it reinforces them.

Our emotions and posture are deeply tied to two hormones:

• Testosterone — often linked to dominance, confidence, and assertiveness.

• Cortisol — the body’s main stress hormone.

  
  

People who feel powerful tend to show higher testosterone and lower cortisol levels. This hormonal mix makes them more optimistic, more willing to take risks, and more confident in their decision-making.

But here’s the intriguing question: If we adopt powerful body language—even if we don’t feel powerful—can we become more confident?

Researchers explored this exact idea by asking participants to hold either a “high-power” pose or a “low-power” pose for just two minutes.

Before and after the pose, participants completed saliva tests to measure hormone levels, rated how powerful they felt regarding certain topics, and completed a risk-taking task (“how likely are you to gamble?”)

Those who held the high-power pose demonstrated a 20% increase in testosterone, 25% decrease in cortisol, and greater willingness to take risks compared to those who held the low power pose. The participants who held the low-power pose demonstrated a 10% decrease in testosterone and a 15% increase in cortisol.

A simple two-minute posture change created measurable hormonal shifts—and influenced behavior.

So what does this mean?? Your body language does more than communicate your emotions. It can change them.

Our body influences our mind.Our mind influences our behavior. And behavior can change our outcomes—socially, academically, professionally, and personally.

Before your next presentation, interview, performance, exam, or any evaluative situation try spending two minutes doing the following:

• Stand tall

• Open your chest

• Relax your shoulders

• Lift your head

• Uncross your arms

• Take up space

  
  

Fake it until you become it.
