📈 Climate Change Impact on Human Brain & Mental Health Highlighted

A recent medical overview by Dr. Srijit Das highlights the severe, often overlooked effects of rising global temperatures and heatwaves on the human central nervous system and mental health. • Overall Mechanism: High environmental temperatures disrupt the hypothalamus (the brain's thermostat), leading to dehydration and severe disturbances in neurotransmitters and synaptic transmissions. • Physical & Neurological Effects: Impaired vasodilation decreases blood flow and oxygen supply to the brain. This causes a failure in the body's cooling mechanisms (reduced sweating), potentially leading to severe heat stroke. • Mental Health & Cognitive Impact: The resulting neurological strain triggers fatigue, confusion, irritable behavior, mood disorders, insomnia, decreased cognitive functions, seizures, and altered consciousness. • Future Outlook: The report emphasizes that while discussion usually focuses on nature, there is an urgent need for large-scale research studies to map changes in hormone levels (serotonin, aldosterone, and cortisol) and fully understand climate change's toll on human health.
