Mental health impacts of anticipation and climate anxiety

Mental health challenges are increasingly linked to the anticipation of future catastrophes, a phenomenon reflected in both philosophical teachings and modern psychological concerns. The Roman philosopher Seneca noted that individuals often suffer more in their imagination than in reality, highlighting how the human brain's evolutionary negativity bias can transform routine uncertainties into chronic anxiety.

This psychological strain is notably manifested as ‘eco-anxiety,’ a term used to describe the chronic fear of environmental catastrophes. While not a formal clinical diagnosis in the DSM, the American Psychological Association defines it as a persistent fear regarding the planet's future. This condition can lead to symptoms such as distress, irritability, sleep disturbances, and panic attacks, often triggered by witnessing extreme weather events or the perceived loss of control over environmental changes.
