Air Quality and Its Role in Mental Health Disorders
There is compelling evidence to suggest that air pollution can lead to neuroinflammation and oxidative stress in the brain. These conditions are linked to a greater risk of mental health disorders. Consequently, scientists believe that exposure to air pollutants may also elevate the risk of dementia and other neurodegenerative conditions.
The Link Between Air Quality and Increased Rates of Depression and Anxiety
Indoor air pollutants have been shown to negatively affect sleep quality. Adequate sleep is crucial for the regulation of various neurobiological processes, such as memory consolidation, detoxification of the brain from toxic metabolic by-products, and maintaining emotional stability and resilience. Poor sleep quality can lead to an uptick in the release of stress hormones like cortisol, resulting in heightened irritability, emotional instability, and diminished emotional regulation capabilities. This hormonal imbalance may increase susceptibility to depression and anxiety. Symptoms of depression can manifest as persistent sadness, feelings of hopelessness, irritability, sleep disturbances, concentration issues, and in severe cases, suicidal thoughts.
