How Climate Change Can Affect Our Mental Health

Learn about the mental health consequences of climate change—and why resilience is critical.

The impacts of climate change are well known: warming oceans, melting glaciers, rising sea levels, severe storms and droughts, and increased heat waves. But negative effects on our mental health are another consequence of climate change. In a public opinion poll conducted by the American Psychiatric Association (APA) in 2019, 48% of respondents said it was definitely true or probably true that climate change is already impacting the mental health of Americans.1


Anxiety and ecoanxiety

According to the APA, “The mental health consequences of events linked to a changing global climate include mild stress and distress, high-risk coping behavior such as increased alcohol use, and, occasionally, mental disorders such as depression, anxiety, and post-traumatic stress.”2 The term “ecoanxiety” has been coined to describe the feelings of frustration and helplessness some people experience when contemplating climate change, and “ecoguilt” captures the feelings some people have when they think about the consequences of their own actions on future generations.3

Disasters and disorders

Additionally, victims of natural disasters such as floods and wildfires may experience depression, anxiety, and post-traumatic stress disorder. Some will even develop ongoing psychological illnesses, according to the American Psychological Association.4 And first responders, the homeless, the poor, people with pre-existing mental illness, children, and pregnant and postpartum women are all at a higher risk of experiencing mental health impacts from weather-related disasters.4

The impacts of increased heat

Rising temperatures are associated with an increase in suicides, dementia, and anxiety disorders.5 The American Psychological Association noted that the risk of disease and death among people with mental illness increases with increases in extreme heat. The association notes that medications are partially to blame because “many psychoactive prescription medications impair the body's ability to regulate temperature.”6

How resilience can help

Climate change is sometimes thought of as something that will happen in the future, but we’re experiencing its impacts—both physically and mentally—right now. Psychologists say that building resilience can help people prepare for, adapt to, and recover from the effects of climate change. Resilience is the process of adapting well to changes, including trauma, adversity, and tragedy. To build resilience, focus on these four components:

  • Create connections—with individuals and groups—so you have access to support.
  • Foster wellness by getting and staying fit and developing methods to handle stress, such as meditation, journaling, prayer, or yoga.
  • Find purpose by taking action. Take small steps toward goals, be proactive, help yourself and others, and reflect on the ways you’ve grown.
  • Embrace a healthy mindset by maintaining perspective, accepting change, adopting an optimistic outlook, and learning from your past.7

As individuals, we may not be able to control climate change, but we can be aware of its impacts on mental health, and we can take steps now to build resilience so we’re better prepared for the future.
