Does telling the truth make you healthier? Here is what the Reel left out. How did people stop lying for 10 weeks? They described their accomplishments as they were. They dropped false excuses for being late. When a question was hard, they answered with a question. A brain scan adds a clue about why lies grow. At University College London, the amygdala, a brain region linked to emotion, was most active the first time people lied for personal gain. Its activity weakened with each further lie. The researchers read this as a negative feeling that fades. Telling the truth on paper helps too. A review of 146 randomized studies found that writing or talking about stressful experiences helped on average. Plato called the worst lie the lie in the soul: being deceived about the highest matters in yourself. (Kelly & Wang, APA convention, 2012; Garrett et al., Nature Neuroscience, 2016; Frattaroli, Psychological Bulletin, 2006; Plato, Republic II) Which small lie would you drop first?

Living truthfully is often touted as a virtue, but recent research adds a compelling layer: honesty might actually improve your health. During a fascinating 10-week experiment conducted by psychologists at the University of Notre Dame, participants who committed to telling fewer lies—both big and small—noticed significant improvements in their mental and physical wellbeing. It wasn’t just about avoiding deception; these individuals reported fewer headaches, reduced tension, and better moods. One of the most intriguing findings comes from brain imaging studies which reveal that the amygdala’s activity peaks the first time a person lies for personal gain but diminishes with subsequent lies. This suggests that the negative emotional response to lying fades over time, potentially making deception easier but not less harmful at a subconscious level. This fading of discomfort can explain why small lies become habitual. Beyond the neurological perspective, writing or talking about stressful experiences, especially truths that are hard to face, also has documented health benefits. A review of 146 randomized studies highlights that articulating stressful or secret experiences relieves mental burdens and enhances emotional resilience. This aligns with the ancient wisdom of philosophers like Plato, Aristotle, and even Buddha, who emphasized the importance of truthfulness for a fulfilled life. Practically speaking, reducing deception can also improve your social relationships. The experiment showed that weeks with fewer lies correlated strongly with smoother conversations and better connection with others, which in turn supported physical and mental health. Being honest helps build trust and decreases the cognitive dissonance involved in maintaining falsehoods. For those considering making honesty a daily practice, an effective approach might be to start small—eliminate harmless white lies like “I’m fine” when you’re not or excuses for lateness. Answering difficult questions with thoughtful questions can also help avoid falsehoods without confrontation. Over time, less lying means carrying less emotional weight. Instead of replaying secrets or fabrications, your mind can focus more on the present moment, contributing to overall wellbeing. In my experience, embracing honesty has been liberating. It’s not always easy at first—there’s often fear about disappointing others or revealing vulnerabilities. But the health benefits, clearer relationships, and peace of mind are well worth the effort. If you’ve ever wondered which small lie to drop first, try observing your daily conversations and notice where honesty feels most natural or impactful. The journey to a healthier, more genuine life may begin with just one truth spoken.
