Why do guys clench their jaw?

Guys may clench their jaw due to stress, anxiety, or frustration, as it can be a physical manifestation of emotional tension. Clenching can also occur during concentration or while sleeping, often leading to discomfort or pain in the jaw over time. Additionally, habits like grinding teeth, known as bruxism, can contribute to jaw clenching. It's a common response to various stimuli and can be alleviated through relaxation techniques and awareness.
