Cod de caniculă, alertă de ”brain fog”. Cum explică neurologii stările de confuzie și deciziile pripite

Hot summer days can lead to mental fatigue due to biological responses to heat. When temperatures rise, the brain reallocates resources to manage thermal stress, causing difficulties in concentration and irritability. This phenomenon, known as 'brain fog', occurs as the brain prioritizes thermoregulation over complex cognitive functions. High temperatures also affect the blood-brain barrier, increasing permeability and potentially leading to mild inflammation, which impairs neuronal communication. To maintain cognitive performance, it is essential to keep the body cool through hydration and staying in shaded or air-conditioned areas.
