Extreme weather events such as hurricanes, floods, drought, extreme heat, and wildfires are occurring at increased rates due to a changing climate and can impact individual mental health. Following disasters such as these, increased levels of anxiety, post-traumatic stress disorder (PTSD), and depression are observed in both people with no history of mental illness and those at risk.

Mental health problems may be short lived or long lasting and may lead to other health consequences. High levels of anxiety and PTSD has been observed among those affected by Hurricane Katrina, and similar observations have followed floods and heat waves. In addition, some extreme weather events may require populations to migrate, which can lead to relocation and adjustment disorders.

Some groups are especially vulnerable to weather-related health impacts, including children, women, the elderly, emergency responders, and those with preexisting physical and mental health problems. For example, some groups may experience adverse health effects during heat waves, which scientists expect to become more frequent and more intense in the coming decades. Patients with mental illnesses such as depression or schizophrenia are at risk during hot weather because their medications may interfere with temperature regulation. Rates of agressive behaviors such as suicide and homicide also increase with high temperatures.

Understanding how a changing climate can impact mental health is important for minimizing adverse health impacts and equipping public health workers with the tools necessary to protect communities from negative health outcomes.
