A closer look
Summer in the city sounds lovely until the air physically stops your sweat from evaporating. Urban heat stress physiology boils down to something terrifying called the 'wet-bulb temperature.' When heat mixes with extreme humidity, your body's sole cooling mechanism—sweating—becomes mathematically useless. The sweat just sits there. As your core temperature skyrockets, your heart pumps furiously to push hot blood to your skin, eventually causing absolute cardiovascular collapse. The concrete jungle traps this heat, turning un-air-conditioned apartments into literal slow-cookers. It’s not just a 'hot day'; it’s an active biological failure.
