Neither eye contact nor arm crossing: The surefire gesture that reveals nervousness, says a criminologist

Gesture, nervousness

Nervous woman.

You’re mid-conversation when you notice a subtle shift in someone’s posture or a fleeting hand movement. Without uttering a word, their body reveals nervousness. While many people fixate on eye contact or crossed arms as signs of tension, a criminologist points to a more reliable giveaway that often hides in plain sight.

A nonverbal communication expert on TikTok, who studies public figures, influencers, and everyday interactions, has identified three common gestures that inadvertently expose hidden stress. Here, we’ll focus on the most telling signal: rubbing your palms together, and explain why it’s harder to control than other nonverbal tells. We also examine additional signals, such as leg rubbing and clothing adjustments, that frequently accompany anxiety.

Rubbing your palms: the stress signal you’re probably overlooking

The criminologist emphasizes that rubbing and interlacing your hands is the clearest indicator of unease. Unlike crossed arms, which may suggest defensiveness, or avoiding eye contact, which can vary widely by culture, this gesture demonstrates a universal attempt to self-soothe. It’s a subconscious way to feel safer during tense moments, such as job interviews or heated discussions.

Besides this, wiping sweat from knees or thighs is another subtle behavior that represents a less obvious version of the classic “sweaty palms” reaction. This is commonly seen when individuals are seated for long periods or in situations that trigger anxiety.

What distinguishes hand-rubbing is its deliberate nature. While general fidgeting tends to be random, the conscious movements of palms and fingers require deliberate muscle engagement, revealing an active effort to appear calm. This intentional gesture is often scrutinized in forensic linguistics and behavioral studies because it indicates a self-regulatory attempt to control emotional responses.

4 other gestures that reveal nervousness

While hand-rubbing stands out as the most reliable indicator, stress frequently manifests through multiple channels. These gestures typically occur alongside that primary tell:

If you notice yourself rubbing your hands or doing some of these other gestures during a presentation or important conversation, consider it a cue to pause, focus on your breathing, and regain composure. Similarly, if you see someone else displaying these signs during a negotiation or social interaction, it might be worthwhile to consider ways to ease the tension.

The key takeaway is that nervous gestures are not inherent flaws but manifestations of your brain’s natural self-protective mechanisms.
