Climate Change and Mental Health: The Hidden Impact of Temperature Fluctuations

Climate change discussions predominantly focus on ecological and economic consequences,frequently neglecting profound psychological implications. This paper examines the criticallink between temperature fluctuations and mental health stability, particularly for vulnerablepopulations with pre-existing conditions such as schizophrenia. By integrating physiologicalmechanisms—including regulatory disruption and the impairment of circadian rhythms—with personal observation and selected case contexts, this note highlights a “cascade ofvulnerability”. Special attention is given to lessons from disaster-recovery regions such asFukushima, arguing that environmental stability must be recognised as a medical necessity.The paper concludes that proactive mental health infrastructure and climate adaptationstrategies are essential for a resilient and equitable society. This paper is non-clinical andnon-diagnostic, and it does not propose diagnostic criteria or treatment protocols.
