A World Health Organization (WHO) report concludes that climate change poses severe risks to mental health. The report, released last year, urges nations to support mental health by responding to the climate crisis and its impact on people globally, especially those suffering from natural disasters, drought, poverty, high temperatures, and living near industrial facilities.
Harsh climate conditions, like hurricanes and wildfires, or dry areas, significantly affect mental health. For instance, cognitive decline can gradually occur after the initial shock of a disaster. Anxiety, feelings of helplessness, depression, post-traumatic stress disorder, and even suicidal thoughts are psychological effects associated with climate change and natural disasters.
The recent fires in California, for example, led to post-traumatic stress disorder among the residents. About 67% of the state’s population reported experiencing fear, phobia, anxiety, sleeplessness, and general fatigue for many weeks following the disaster.
Moreover, climate change affects the mental health of people who have not personally experienced natural disasters. Just following the news of such events can lead to anxiety and fear.
WHO also says that ongoing climate fluctuations, rising temperatures, and worsening air pollution could be a primary cause of depression, violence, and severe mood swings, as well as an increase in mental health-related emergency department visits.
Can climate and weather changes impact the mental health of certain people more than others? The answer is yes. Global statistics indicate that individuals with underlying mental illnesses or specific addiction problems are more likely to die due to increased temperatures or humidity. According to the WHO report, about 35% of the world’s homeless population suffering from severe mental conditions or chronic diseases are more vulnerable to the adverse effects of climate change.
Globally, climate change distress is increasing among the youth. A WHO survey in ten countries revealed that 84% of youth between 16 and 25 years old were moderately anxious about climate change, and nearly half reported that it affected their daily and professional lives. The study also found that exposure to harsh climate events like hurricanes, droughts, and floods during pregnancy increases the risk of various mental or psychological illnesses in children.
