Constant exposure to negative news is taking a toll on mental health, with research showing a link between consuming distressing events – from global conflicts to natural disasters – and increased anxiety, depression, and even PTSD. Building on studies dating back to the aftermath of 9/11, a growing body of evidence reveals how the brain’s natural threat-detection system can be overwhelmed by a relentless news cycle, leading to chronic stress and trauma. This article examines the psychological mechanisms at play, explores why some individuals are more vulnerable, and offers guidance on mindful news consumption to protect well-being.
The Psychological Toll of Constant News Exposure
Psychologist and physician Roxane Cohen Silver first recognized the potentially damaging psychological effects of media coverage during and after the 1999 Columbine High School shooting and the September 11th terrorist attacks.
Research following those events, tracked over three years, revealed that individuals with greater exposure to news about the terrorist attacks reported increasing mental and physical health problems over time. This highlights the significant impact that sustained exposure to distressing news can have on well-being.
Two decades later, the constant stream of news today can disrupt the body’s stress response and lead to psychological issues that can persist for years.
How Does News Trigger Your Stress Response?
The human brain is wired to focus on threats. This instinct, which once protected our ancestors from predators, now leaves many feeling overwhelmed by alarming headlines.
When a threat is perceived, the “fight or flight” response is activated, releasing hormones like cortisol and adrenaline. These hormones provide the energy and mental clarity needed to confront the perceived danger.
Normally, the body returns to a state of equilibrium once the threat has passed. However, continuous exposure to negative news keeps this system in a perpetual state of activation.
This chronic activation can disrupt the brain’s reward system. Activities and relationships that once brought joy may become less appealing, leading to feelings of fatigue, hopelessness, and anxiety.
Indirect Exposure to Traumatic Events Can Trigger Post-Traumatic Stress Disorder (PTSD)
Research conducted after the 2013 Boston Marathon bombing demonstrated the powerful impact of social media.
Individuals who spent more than six hours a day consuming media coverage of the event reported more acute psychological symptoms – including nightmares, sleep difficulties, and intrusive memories – than those who were physically present at the scene. This finding underscores how vicarious trauma can be as impactful as direct experience.
Studies on other disasters, such as the Covid-19 pandemic, hurricanes, the Ebola outbreak, and the Great East Japan Earthquake and tsunami, have similarly shown that exposure to distressing news elevates stress levels and negatively affects mental health, both in the immediate aftermath and in the long term.
Silver’s team also found that repeated exposure traps the brain in a cycle of rumination. Each disturbing headline or image re-triggers the trauma, forcing the mind to revisit it repeatedly.
Constant Bad News Keeps Us Trapped in Trauma
Following the Boston Marathon bombing, Silver sought to understand who turns to media most during traumatic events.
Her team examined media coverage of the 2016 Pulse nightclub shooting in Orlando, Florida. The findings revealed a self-perpetuating cycle: people encountered disturbing news, felt distressed, clicked on more news, and became even more distressed.
This cycle can affect anyone, but those who identify with the victims or are already prone to fear and anxiety are at higher risk of becoming caught in it. They then become hyper-vigilant for future threats in an attempt to alleviate their anxiety.
Psychologist E. Alison Holman stated, “You start to constantly worry about whether something bad is going to happen again.”
According to Silver, this leads to a greater likelihood of turning to media during the next disaster and becoming re-immersed in the same traumatic events. “It feels like an unbreakable cycle,” Silver said. “We call this ‘doomscrolling.’”
Here’s How Repeated Stressors Affect Us
The media landscape has changed significantly since Silver began her research. Today, a constant stream of news flows through our phones, delivering bad news at any moment. Holman notes that visuals on social media are more striking than ever, and algorithms ensure we see more of what we click on.
2020 was a stark illustration of how damaging relentless news cycles can be, with the pandemic, economic downturn, and weather-related disasters all unfolding simultaneously. Recent years have been no different: the wars in Gaza and Ukraine, political unrest, mass shootings, floods, and hurricanes have trapped viewers in a cycle of crisis.
“When events happen one after another, your body can’t regulate itself,” Holman explained. “The evidence is undeniable; these accumulated traumas, published on multiple platforms, are psychologically damaging us.”
Constant Bad News Traps Us in Trauma
A Guide to Consuming News ‘Mindfully’
To protect your mental health without disconnecting from the news entirely, experts recommend the following strategies:
Body Awareness: Take a deep breath before picking up your phone. If your heart rate increases or your shoulders tense while scrolling, it’s time to stop.
Set Time Limits: Instead of checking the news throughout the day, designate one or two 15-20 minute windows and use a timer.
Avoid Visuals: Professor Silver covers up graphic or disturbing images while reading the news. This is a simple but effective way to protect your brain from visual trauma while staying informed.
When does sleep disturbance or anxiety following news consumption move from being a ‘normal reaction’ to ‘secondary trauma’ requiring professional treatment, and is it possible for an individual to recognize this?
“Prolonged exposure to negative news content can lead to increased worry about everyday life events, increased anxiety levels, feelings of unhappiness, disinterest, lack of motivation, a decrease in the expectation of positive emotions, hopelessness, and despair, as well as cognitive symptoms such as difficulty concentrating, forgetfulness, difficulty remembering old information, and difficulty learning new information,” said Psychiatrist and Associate Professor Taha Can Tuman.
“In addition, muscle tension, fatigue, difficulty falling asleep, difficulty staying asleep, and physical symptoms such as palpitations, shortness of breath, tremors, and sweating may occur. If we realize that this situation is causing deterioration in our quality of life, social, professional, and family functionality, it may be beneficial to reduce our exposure to this content and seek psychiatric support if necessary.”
Why Are Some People More Susceptible to Digital Trauma?
Doç. Dr. Tuman stated, “We can say that individuals undergoing treatment for depression and anxiety disorders are more susceptible. In addition, those with a history of post-traumatic stress, high anxiety sensitivity and perceived stress levels, and those with personality traits such as perfectionism and intolerance of uncertainty are more susceptible.”
How to Reduce the Stress Response
“How can we biologically ‘reset’ the stress response disrupted by news and the inability to enjoy anything?” we asked Doç. Dr. Taha Can Tuman, who responded, “Long-term exposure to negative news content can lead to a decrease in hippocampal volume, making us more susceptible to stress. We can say that those with high intolerance of uncertainty, high anxiety sensitivity, and high perceived stress levels are more affected.” He then added:
— First, it is necessary to reduce exposure to negative content to reduce the repetitive stress response.
— Afterwards, focusing more on daily life, practicing mindfulness exercises, setting goals and objectives for ourselves, socializing, and exercising will help reduce the symptoms associated with chronic stress.
— However, if our quality of life and functionality are impaired, and if there is a presence of widespread anxiety disorder, moderate or severe depression, medication and psychotherapy support may be necessary.
