As the climate crisis intensifies, a disturbing trend has emerged - individuals with mental health conditions such as schizophrenia, bipolar disorder, and anxiety are facing a potentially lethal threat. A recent study conducted in British Columbia revealed that during a record-breaking heat wave in June 2021, 8% of the individuals who lost their lives due to extreme heat had been diagnosed with schizophrenia. This alarming statistic surpasses the risks posed by other medical conditions, highlighting the urgent need for addressing this issue.

Experts and healthcare professionals express concerns that rising temperatures, associated with the climate crisis, have not only led to the drying up of crops and devastating wildfires but also pose significant dangers to the mental wellbeing of vulnerable individuals. Studies have linked increasing rates of suicide attempts and visits to mental health-related emergency departments to the escalating temperatures. Furthermore, long-term exposure to air pollution, which worsens due to the climate crisis, has been linked to heightened anxiety and an increase in suicides.

The vulnerability of individuals with mental health conditions to the threats of extreme heat and air pollution is attributed to various factors. The anterior hypothalamus, known as the body's thermostat, plays a critical role in regulating body temperature. Dr. Peter Crank, lead author of a study on the associations between temperatures and hospital admissions of individuals with schizophrenia, explains that the impaired neurotransmission of information to this part of the brain, caused by conditions such as bipolar disorder, schizophrenia, or manic-depressive disorder, contributes to a reduced capacity to regulate body temperature. Additionally, lower levels of brain chemicals like serotonin and dopamine, commonly found in individuals with mental health conditions, further impact the body's ability to regulate temperature effectively.

Medications used to treat mental health conditions can also pose additional risks. Antipsychotic medications, such as aripiprazole, olanzapine, risperidone, quetiapine, and lurasidone, have been found to have the greatest effect in impairing the body's ability to sweat and regulate core temperature. Stimulant medications for ADHD and anti-anxiety medications can also contribute to this problem. Furthermore, lifestyle habits crucial for managing mental health symptoms, including sleep, can be disrupted by warm temperatures.

The issue is further exacerbated by the fact that individuals with mental health conditions, particularly those diagnosed with schizophrenia, are more susceptible to homelessness. During heat waves, the lack of access to air conditioning, often experienced by the homeless population, places them at increased risk of heat-related illnesses or even death. Additionally, behaviors associated with certain mental health conditions, such as psychosis, can lead individuals to fail to recognize or respond appropriately to overheating.

To address this crisis, experts emphasize the need for comprehensive support. While discontinuing medications is not recommended, individuals are encouraged to discuss potential risks with their healthcare providers. They are advised to take precautions, such as staying in cooler environments, maintaining hydration, and avoiding the hottest parts of the day. The expansion of cooling centers and accessible resources is essential, along with increased funding for research to better understand the impact of heat on mental health.

In the face of the ongoing climate crisis, tackling the root cause remains crucial. However, individuals and communities can play an active role in protecting vulnerable populations. Wearing appropriate clothing, using sunscreen, and taking cold showers can help regulate body temperature. Furthermore, getting involved in climate advocacy groups and working towards meaningful change can help alleviate anxiety associated with climate change. Practicing empathy and awareness, such as carrying water bottles and contacting emergency services when encountering someone in distress due to extreme heat, can make a significant difference.

The climate crisis not only threatens our planet but also the mental health of those already grappling with various conditions. Urgent action is required at both individual and policy levels to safeguard the well-being of vulnerable individuals in the face of rising temperatures and increasing environmental challenges.
