Psychologist Jenny Taitz presented a talk on how stress functions as a contagion and provided techniques to interrupt the cycle of mental spirals.
Understanding the contagious nature of stress is critical because it explains how individual tension can snowball into collective anxiety within a group. By identifying the mechanisms of this spread, individuals can apply targeted resets to prevent a total emotional collapse.
Taitz delivered the presentation on Nov. 10, 2025 [1], during the TEDNext 2025 conference [2]. She said that stress does not only exist within a single person but can move from one individual to another. This phenomenon creates a loop where stressful moments intensify as they are shared, often without the participants realizing the source of the tension.
To combat this, Taitz introduced small, immediate reset techniques designed to break the stress spiral. These methods serve as a circuit breaker for the brain, allowing a person to shift out of a fight-or-flight response and return to a state of equilibrium. The goal of these resets is to stop the momentum of a stressful episode before it becomes overwhelming.
Taitz said that the ability to influence the emotional state of a room is a two-way street. While tension can spread rapidly, the opposite is also true. "Stress is contagious — but so is calm," Taitz said.
By implementing these quick-reset methods, Taitz said individuals can not only protect their own mental well-being, but also prevent the spread of stress to those around them. The presentation focused on the practicality of these tools, suggesting that brief, intentional interventions are more effective than attempting to manage a full-scale crisis after it has already peaked.
“Stress is contagious — but so is calm.”
The focus on 'stress contagion' shifts the perspective of mental health from an individual struggle to a social dynamic. By framing calm as an equally contagious state, the research suggests that individual emotional regulation can act as a public health tool, potentially reducing collective anxiety in high-pressure environments like workplaces or schools.
