The Cognitive Burden of Secrets

Keeping a secret requires continuous mental effort to monitor one's speech and actions, ensuring that hidden information isn't accidentally revealed. This ongoing vigilance can create cognitive tension, leading to emotional stress and anxiety. Research by psychologist James Pennebaker shows that discussing or confessing deeply held secrets can positively impact health by reducing doctor visits and lowering stress hormone levels. The act of revealing a secret can therefore serve as a powerful mechanism for alleviating mental burdens.
