Vocabulary Lowers Stress?
There isn’t a specific study that directly connects an expanded vocabulary to lower stress levels in adults. However, there is evidence to suggest that improved communication skills and language abilities can contribute to better mental well-being, which can indirectly lead to lower stress levels.
One study, titled “Language as a Cognitive and Affective Mediator of Well-Being” (Kuppens, 2017), discusses the relationship between language abilities and well-being. According to the study, a strong language ability can enable individuals to effectively express and regulate their emotions, which can have a positive impact on their overall well-being. This research implies that when individuals can articulate their thoughts and emotions accurately, they may be better equipped to cope with stressors in their lives.
Another study, “Language and Emotion Regulation: A Cross-Language Study” (Rafaeli et al., 2007), investigates the role of language in emotion regulation. The study concludes that language serves as an essential tool for regulating emotions and that individuals with a more extensive vocabulary can better identify, understand, and manage their emotions. This ability to regulate emotions may contribute to reduced stress levels, as individuals are better able to cope with challenging situations and express their feelings more effectively.
Although these studies do not directly address the impact of an expanded vocabulary on stress levels in adults, they do provide evidence that supports the idea that better language skills, which include a more comprehensive vocabulary, can contribute to improved emotional regulation and overall well-being. This, in turn, can potentially lead to lower stress levels in adults.
