Heatwave Affects Brain Function, Causing Mental Fog and Irritability
Extreme heat, or canicula, is impacting brain function, leading to common issues such as forgetfulness, loss of concentration, and increased irritability. These symptoms are collectively referred to as 'mental fog.'
Experts highlight that the brain is the body's most significant energy consumer, utilizing approximately 20% of the body's total energy despite accounting for only 2% of its weight. This high energy demand makes the brain particularly vulnerable to physiological stress caused by excessive heat.
Elevated temperatures impose significant physiological stress, impacting cognitive functions due to the brain's high metabolic rate. The observed 'mental fog' and irritability likely stem from disruptions in neural processes and neurotransmitter balance exacerbated by heat. Future urban planning and public health strategies must account for the increasing frequency of heatwaves, integrating measures to mitigate their neurological impact, such as improved cooling infrastructure and public awareness campaigns on heat-related cognitive risks.
