Psychologists explain why bad news can harm both mental and physical health. They tie the reaction to an evolutionary response that helped the body deal with serious threats.
Bad News Triggers Changes in the Body
When something unfortunate happens, the body switches into “fight or flight” mode. At the neurobiological level, the sympathetic nervous system governs this response. It sends signals from the spinal cord to the body’s major organs, including the heart and intestines, preparing a person to either fight or flee.
A key part of the fight-or-flight response is that digestion stops so blood and energy can be redirected to the limb muscles. In some people, that sudden shift shows up as nausea, vomiting, or diarrhea. In short, bad news makes the body perceive a threat, and the body reacts by activating survival mode.
That advice is easier said than done. Slow your breathing. Make a list of what you can control and what you can’t. For the things you can influence, make actionable plans to improve the situation. Use distractions, exercise, and meditation to relax and manage stress over time. Ask for help from friends and family or seek professional support if nausea from bad news persists.
