The possibility that climate change might have a substantial impact not only on the body but also on the mind has emerged from approaches adopted in an academic discipline called economic statistics. Scientists suggest that global warming and natural disasters may cause mental health to deteriorate, resulting in an increase in psychiatric disorders such as depression. There is also data indicating that crime rates increase as temperatures rise. The WHO has pointed out that climate change poses a serious risk to mental health. In addition to measures to curb temperature rises, we need a health care system that supports both mental and physical health.
