The Secret Science of Power Poses: Can Your Body Really Change Your Mind?

Can standing like a superhero for two minutes really make you more confident? According to Amy Cuddy’s research, the answer is yes—at least in the short term. Power poses, or expansive postures, have been shown to increase testosterone and decrease cortisol, priming you for success.

How Power Poses Work

When you adopt an open, expansive posture, your body sends signals to your brain that you are safe and in control. This triggers hormonal changes that make you feel more assertive and less anxious. While some studies have debated the magnitude of these effects, the consensus is that body language does influence your mindset and behavior.

Authenticity Matters

It’s not just about striking a pose. Presence is about synchrony—when your body language matches your words and emotions. People can sense inauthenticity, so the goal is to use these techniques to support genuine confidence, not to fake it.

Practical Applications

Try a power pose before an interview, presentation, or difficult conversation. Pair it with self-affirmation and mindful breathing for maximum effect. Many athletes, performers, and executives use these rituals to calm nerves and boost performance.

The Debate and the Evidence

Some scientists have challenged the extent of power pose effects. However, most agree that posture, body language, and preparation rituals can influence how you feel and how others perceive you. The key is to use these tools as part of a broader strategy for confidence and presence.

Conclusion

Power poses aren’t magic, but they are a useful tool in your confidence toolkit. Combined with self-reflection and authentic engagement, they can help you show up as your best self.
