Researchers are able to analyze how the human brain and body respond to stimuli that may be perceived as painful. By subjecting participants to a series of images and words that are designed to provoke the nervous system, we simulate the same experience that people encounter when consuming news on a daily basis. Some of the most intense materials we use in our studies are actually sourced from news reports.
Over time, changes in brain activity patterns emerge, impacting the body’s regulatory systems. The brain regions associated with the “fight or flight” response undergo alterations, which are essential for maintaining the functionality of the nervous system, immune system, and metabolism.
As a result, we observe physiological responses in participants such as increased heart rate, sweating, and elevated cortisol levels, even though they are seated comfortably in a lab setting. Just the thought of distressing events can trigger significant electrochemical changes in the body.
For example, our research has investigated how individuals react to news coverage of events like the 2013 Boston Marathon bombing. When news articles contain a high proportion of negative language, our participants reported heightened distress and displayed stronger physical reactions to the images associated with the bombing.
Unexpected or ambiguous news stories can also intensify feelings of distress, such as reports on government inaction towards rising infection rates and carbon emissions. When the brain processes information that is slightly more challenging than expected, it can strain the body’s metabolism and create discomfort.
Although a degree of discomfort may be a necessary aspect of being informed, constant exposure to negative news can lead to a cumulative burden, especially as news outlets tend to prioritize negative stories and language.
Negative news often spreads quickly through social media platforms, rewarding news outlets that emphasize negative content and perpetuating a cycle of negativity. Consuming excessive negative news may leave individuals feeling overwhelmed and drained, even if their personal experiences are relatively positive.
To counter the effects of negative news, it’s important to balance exposure with positive content. Engaging in activities that bring joy and relaxation can provide a respite for the nervous system and overall well-being.
For instance, focusing on stories of resilience, heroism, and kindness in challenging circumstances can help individuals cope with distressing news. Our research showed that participants reported lower levels of distress when presented with positive content related to the Boston Marathon bombing, and were less reactive to associated images.
Additionally, it’s advisable to avoid consuming negative news while eating, as stress can impact the body’s metabolism and lead to weight gain over time.
