How does air pollution affect the brain according to Dr. Astik Joshi?

Dr. Joshi explains that pollutants cross the blood-brain barrier, causing inflammation and oxidative stress that disrupt brain function and mood-regulating chemicals.

What are the psychological effects of living in Delhi's polluted air?

Living in high pollution can lead to increased anxiety, lower mood, irritability, and depressive symptoms due to disrupted brain chemicals.

Pollution Poisons the Mind: Delhi's Air Threatens Brain Health

Air pollution in Delhi has evolved into a significant hazard for brain health and mental well-being, presenting risks beyond its known respiratory and cardiovascular impacts. Exposure to pollutants, particularly PM2.5, allows toxic particles to breach the blood-brain barrier. Once in the brain, these particles initiate inflammatory responses and oxidative stress, interfering with normal neurological functions.

This environmental stressor amplifies the body's biological stress response, disrupting essential neurotransmitters such as serotonin and dopamine. These chemicals are vital for regulating mood, sleep patterns, and emotional equilibrium. Consequently, prolonged exposure to smoggy conditions in highly polluted cities like Delhi can manifest as heightened anxiety, lower mood, increased irritability, and depressive symptoms.
