The mental health crisis associated with climate change is an ongoing global health concern, with Bangladesh being one of the most vulnerable countries. Approximately one in eight individuals worldwide experiences a mental health crisis, and it is estimated that 4.5% of the population in Bangladesh suffers from anxiety. This review intends to provide relevant information on how climate change impacts mental health in Bangladesh. The study utilised 12 published original articles selected from a pool of 366 relevant articles identified through searches in Scopus, Web of Science, and PubMed databases. The eligibility criteria focused on studies reporting mental health outcomes based on data from Bangladesh and published between 2014 and 2024. The finding highlights that climate change induced disasters like floods, cyclones, river erosion, and drought has significant impacts directly on several mental diseases such as depression, anxiety, stress, sleep disorder and post-traumatic stress disorders (PTSDs) while family violence, conflicts, displaced, loss of family or relatives and assets contributing mental health indirectly. Moreover, women, elder and adolescents are the worst victims of mental health crises due climatic factors. Evidence-based interventions, the development of adaptive strategies, and livelihood supports are crucial to reduce the impact of climate change induced disasters on mental health in Bangladesh.
