A 2026 narrative review in Brain Sciences synthesizes over 60 studies across chronobiology and psychiatry, concluding that biannual DST shifts function as population-level circadian stressors that amplify symptoms in depression, bipolar disorder, anxiety, PTSD, ADHD, and psychosis. Unlike RCTs, this is an observational synthesis without original data collection or effect-size meta-analysis, limiting causal claims but highlighting consistent patterns from real-world clock changes. The source correctly flags risks like delayed sleep adjustment and urges anticipatory clinician guidance plus morning light exposure, yet underplays documented links to workplace injuries and cardiovascular events seen in prior observational cohorts. Related evidence from a 2008 Swedish registry study (n>1.5 million) showed a transient 5% rise in myocardial infarctions post-spring transition, while a 2019 analysis of U.S. traffic data linked fall-back shifts to increased fatal crashes. These patterns suggest DST imposes measurable neuropsychological costs rarely quantified in mainstream policy debates. Permanent standard time aligns better with solar cues than permanent DST, a stance supported by the review's authors but absent from many economic arguments favoring extended evening light. No conflicts of interest were declared in the primary paper.
