In today's fast-paced world, it is easy to get caught up in the constant stream of news and current affairs. With the ever-present nature of social media and 24-hour news cycles, it can feel like we are always connected and informed. However, this constant access to information can have a detrimental effect on our sleep. The impact of world news on our sleep is a pressing issue, as highlighted by the long-running news program World News Tonight, which has been airing since 1953. Anchored by the likes of Peter Jennings and currently David Muir, the show covers major events and stories from across the globe, providing viewers with the latest information and analysis. While staying informed is important, the impact of news consumption on our sleep cannot be overlooked, especially during stressful times such as election seasons.

What You'll Learn

Political anxiety and stress
To break this cycle, it is essential to set limits on your news and social media consumption, especially before bedtime. This practice, known as a "doomscrolling" plan, involves setting aside a specific time frame for consuming news and using social media. It is also beneficial to choose reliable news sources and fact-based content over constantly trending topics.
Additionally, engaging in meaningful activities, such as volunteering or constructive discussions, can provide a sense of purpose and alleviate feelings of helplessness and stress. Practicing self-care, mindfulness, and focusing on your breath or movement can also increase resilience and reduce overstimulation.
It is important to recognize that political stress can affect your mental health and disrupt your routine. Being proactive in addressing these issues and adopting healthy coping mechanisms are crucial steps in managing political anxiety and stress.
During election seasons, in particular, it is common for individuals to experience heightened political stress and anxiety. The uncertainty of outcomes and the potential for extended periods before official results can add to the tension. It is essential to be mindful of your mental health and well-being during these periods and seek healthy ways to manage your stress.

Emotional contagion
The constant stream of news, social media debates, and uncertain outcomes can make it difficult to relax and fall asleep. This is where the concept of "emotional contagion" comes into play. Emotional contagion refers to the phenomenon where people instinctively and unconsciously mirror or mimic the emotions of those around them. This can occur through facial expressions, vocalizations, postures, and movements, as well as direct and indirect social interactions.
Elaine Hatfield, John Cacioppo, and Richard Rapson, in their 1993 research, define emotional contagion as "the tendency to automatically mimic and synchronize expressions, vocalizations, postures, and movements with those of another person, and, consequently, to converge emotionally." They propose a two-step process: first, we imitate others' expressions, and second, our own emotions change based on the non-verbal signals we give off. For example, if someone smiles at you, you will likely smile back, and this act of smiling can make you feel happier. Similarly, if a friend or partner is angry, you may find yourself feeling that anger as well. This phenomenon is tied to empathy, with positive feelings leading to deeper intimacy and negative feelings bringing tension and conflict.
To break the cycle of emotional contagion affecting sleep, it is crucial to set limits on news and social media consumption before bedtime. Engaging in meaningful activities, such as volunteering or constructive discussions, can provide a sense of purpose and alleviate feelings of stress and helplessness, promoting better sleep. Compartmentalization, which involves shelving negative thoughts and emotions for a more appropriate time, can also be a useful strategy.

Sleep and mental health
The bidirectional relationship between sleep and mental health is complex and influenced by numerous factors. For example, stress and rumination are known sleep disruptors. The constant barrage of news, social media debates, and uncertain outcomes can make it challenging to relax and fall asleep. This negative cycle of poor sleep and increased stress can adversely affect overall well-being.
Additionally, bedtime procrastination, the habit of delaying sleep by scrolling through social media or watching videos, can disrupt sleep schedules. This form of procrastination is particularly challenging because, as sleepiness increases, willpower decreases, impairing decision-making and judgment. Furthermore, the psychological phenomenon of "emotional contagion" can cause individuals to mirror the anger and intensity displayed on screens, leading to feelings of agitation and distress.
On the other hand, sufficient sleep, particularly rapid eye movement (REM) sleep, is vital for the brain's processing of emotional information. During REM sleep, the brain evaluates and consolidates thoughts and memories, especially positive emotional content. A lack of sleep can negatively impact mood and emotional reactivity, increasing the risk of mental health disorders and suicidal ideation.
To improve sleep quality and mental health, it is essential to set limits on screen time and social media consumption before bedtime. Engaging in meaningful activities, such as volunteering or constructive discussions, can alleviate feelings of helplessness and stress, promoting better sleep and supporting mental well-being. Adopting healthy sleep habits and, if needed, seeking professional help for chronic insomnia are crucial steps to enhance sleep quality and overall mental health.
