New Delhi: The extreme heatwave has grappled India mercilessly, with temperature rising every passing day. The Indian Meteorological Department (IMD) has issued red alert in various states of the northern part of the country. Heatwave has wreaked havoc in people’s life majorly affecting their health. Climate change, a global crisis primarily recognised for its environmental impacts, also poses significant threats to human brain health.
Extreme temperature, air pollution and other climate changes can lead to neurological conditions.
In conversation with News9, Dr Shivaram Rao K, Consultant Neuro Physician, Yashoda Hospitals Hyderabad said, “Elevated temperatures have been linked to a rise in neurological conditions such as stroke and multiple sclerosis. Heatwaves, becoming more intense due to climate change, can cause migraines and worsen symptoms in individuals with pre-existing neurological conditions. The brain is particularly sensitive to temperature changes, and prolonged exposure to extreme heat can lead to heatstroke, which may cause permanent brain damage or death.”
“Air pollution, another byproduct of climate change, is a vital component affecting brain health. Pollutants like fine particulate matter (PM2.5) and nitrogen dioxide can enter into the bloodstream and reach the brain, causing inflammation and oxidative stress,” said Dr Rao.
Studies have shown a link between air pollution and cognitive decline, dementia, and even psychiatric problems such depression and anxiety. Children and the elderly are at higher risk, with air pollution damaging the brain development of young children.
Climate change can lead to brain injuries
Extreme weather events, including hurricanes, floods, and wildfires, are also increasing in frequency and intensity due to climate change. According to Dr Roa, “These events can lead to traumatic brain injuries (TBIs) and exacerbate stress and mental health issues. Displacement, loss of property, and the stress associated with these events can increase the incidence of post-traumatic stress disorder (PTSD), anxiety, and depression, which have long-term effects on brain health.”
“Furthermore, the indirect effects of climate change, such as food and water insecurity, can lead to malnutrition, impacting brain function and development. The stress of living in a constantly changing and increasingly hostile environment can also exacerbate mental health issues and neurological conditions.”
Hence, climate change is not only an environmental issue but a significant public health concern. Its effects on brain health are profound, with the potential to worsen neurological conditions and mental health issues globally. Immediate action is essential to mitigate these impacts and protect future generations.
