Research supports the link between neuroticism and poor health, as people high in neuroticism are more prone to anxiety, worry, and stress. This personality trait has been associated with mental disorders like depression, as well as physical illnesses such as heart disease and certain cancers. Studies suggest that neuroticism may lead to unhealthy behaviors such as smoking and lack of physical activity, and chronic stress can impact the body over time. Neuroticism has also been linked to chronic inflammation, impaired sleep, decreased levels of brain-derived neurotrophic factor (BDNF), and reduced gut microbiome diversity. However, personality traits can be modified through well-designed treatments, such as the unified protocol, to help manage intense emotions and reduce neurotic tendencies.
