Which nonverbal action does NOT help effective communication?

The constant adjustment of glasses can be distracting and may signal nervousness or discomfort, making it harder for the audience to focus on the message being conveyed. Effective communication relies heavily on the ability to engage and maintain the listener's attention, and nonverbal cues play a significant role in that process.

In contrast, keeping a low and relaxed voice helps create a calm atmosphere, making the communication more approachable. Leaning slightly toward the speaker indicates attentiveness and interest, which fosters connection and engagement. Smiling and showing interest effectively convey warmth and positivity, encouraging a more open dialogue. Thus, while other nonverbal actions enhance communication, the act of constantly adjusting one's glasses detracts from it.
