Are you ready to shift your language and elevate your mental health? Let’s get started on a journey to a more positive you!

Positive shifts in language use

Our choice of language has a substantial impact on our emotional state. The study “Natural Emotion Vocabularies as Windows on Distress and Well-being,” conducted by Pennebaker and colleagues, reveals that people’s natural language usage patterns can influence their overall mental health. Those with a richer vocabulary for describing positive emotions tend to experience higher levels of well-being, while those with a greater arsenal of words for negative emotions often display more depressive and anxious traits.

This phenomenon is not solely about recognizing words; rather, it’s about the frequency of use in daily speech and writing that matters. In a series of writing exercises, participants focused on expressing their emotions about negative experiences. Over time, their language gradually shifted from predominantly negative to more balanced, with an increase in positive terms, potentially leading to improved mental health.

Participants were instructed not to scrutinize their choice of words during the writing process. The content included facts about a distressing event, the emotions felt during and after the event, and any perceived connections with other life aspects, whether past, present, or future. The exercise was personal and cathartic rather than for an audience.

Furthermore, positive mental and physical changes have been observed in individuals who followed this specific writing protocol. It’s been shown to relieve symptoms of chronic anxiety, insomnia, arthritis, cancer, lupus, fibromyalgia, and irritable bowel syndrome. These improvements were not just short-term but had lasting effects. While it isn’t a cure-all, it highlights the potent influence of emotional processing on physical health.

The studies contrasted a control group engaged in regular journaling against those involved in the structured writing exercise, ensuring that the reported health benefits were directly associated with the specific emotional content of their writing. This approach to harnessing the profound connection between emotional expression and physiological change validates the therapeutic power of language and self-reflection.

Neuroplasticity and rewiring

Neuroplasticity, or the nervous system’s ability to rewire itself in response to experience, is a concept that has profound implications when it comes to stress and trauma. Extended periods of stress typically result in negative physical health outcomes, but when individuals engage in specific tasks like writing about their traumatic experiences, the results can be quite surprising. Such writing protocols have been shown to induce positive effects on the immune system and overall health.

Examining the role of neuroplasticity in this context reveals that by recounting stressful or traumatic events—particularly with a focus on the facts, the emotional impact then and now, and any associations—individuals tap into their neural maps, or schemas. This essentially carries the potential to alter the brain’s predictive capabilities, which are largely shaped during childhood’s critical periods through passive experience.

Another interesting aspect centers around how parts of our brain, such as the prefrontal cortex (involved in planning, self-concept, and assessment of potential outcomes), interact with subcortical structures, like the hypothalamus (regulating aggression, temperature, and sleep-wake cycles) and the amygdala (involved in threat detection). During the recollection of traumatic experiences, neuroimaging studies have shown a pattern where prefrontal cortex activity diminishes, while subcortical structures’ activity initially increases.

However, revisiting these stressful memories through structured writing can lead to a change in this neural activity over time. The repeated deliberate reflection in a guided manner may be a critical factor in achieving long-lasting mental and physical health improvements due to the engagement and alteration of these neural pathways. Such practices involve a complex interplay between the emotional states and our physiological responses, tapping into what can be considered a lynchpin mechanism in the realm of neuroscience and psychological therapy. By understanding and engaging neuroplasticity through structured recollection and expression, individuals can potentially influence their overall well-being in a positive and transformative manner.

Deeper recollection and coherence

As individuals repeatedly write about a traumatic event, they tend to delve deeper into their memories, resulting in heightened emotional distress yet providing a more coherent narrative each time. According to Andrew D. Huberman, with successive writing sessions, people not only change their language when describing their feelings but also construct a story-like structure around their experiences. This is significant because it reflects an increasing level of truth-telling and personal honesty. Huberman emphasizes the importance of factual recounting in this exercise: you detail the event as you remember it, express how it made you feel—a response only you can factually report—and explore the connections between different experiences related to the event.

The process, while distressing, has been shown through neuroimaging to enhance activity in key areas of the prefrontal cortex, which correlates with symptom improvement related to trauma and stress. Huberman discusses the counterintuitive nature of this process, pointing out that while initially distressing recollections typically decrease prefrontal cortex activity, in this context, recalling those memories with strong emotional ties actually boosts ongoing activity in the prefrontal cortex. This spike in activity is linked to neuroplasticity—our brain’s ability to rewire itself—which, in adults, is a product of atypical neural states marked by heightened levels of catecholamines like dopamine, epinephrine, and norepinephrine. These uncomfortable states trigger the nervous system to reorganize, and the actual rewiring takes place during deep sleep or deep relaxation.

Huberman draws attention to two main concepts from recent psychological and neuroscience research: first, that stressful and traumatic experiences often lead to a fractured representation of events, causing confusion and a lack of coherent narrative; second, that truth-telling, especially with a coherent narrative structure, leads to increased and sustained activity in the prefrontal cortex, enhancing its role in forming coherent narratives and addressing the trauma. Through the structured process of writing and recounting one’s truth, even negative or traumatic experiences can be re-framed in a way that provides relief and contributes to mental and physical well-being.


Harnessing the power of language is akin to rewiring our brains—transforming our emotional landscape through deliberate shifts in vocabulary. As we enrich our language with positive terms and processes, not only do we pave the way for heightened well-being, but we also engrain deeper recollection and coherence in our life narratives. It turns out, the words we choose to express ourselves aren’t just reflections of our internal world; they shape it. By consciously tweaking our everyday language, we might just write our way to a happier state of mind.
