Over the last decade, more and more people have been moving to big cities and leaving quiet rural towns for a variety of reasons, including career possibilities, cultural attractions, higher education, diversity, and convenience. They provide a concentration of jobs in diverse industries, top-tier universities and colleges, an abundance of cultural attractions, superior transportation systems, greater retail alternatives, and a thriving nightlife. Yet, residing in a big city also comes with its share of difficulties, including higher living expenses, an increase in noise and pollution, and a greater sense of social isolation.

Moreover, living in large communities can lead to “stimulus overload,” according to psychologist Stanley Milgram. In turn, the fight or flight response, a physiological and psychological response that gets the body ready to fight or flee from perceived danger, can be set off by the sensory overload brought on by living in large cities. Urban living’s fast-paced, high-stress environment can cause the sympathetic nervous system to be activated and stress hormones like cortisol and adrenaline to be released. Other constant sensory stimulations include noise, crowds, and bright lights. Chronic sensory overload can eventually cause an exaggerated fight-or-flight reaction, which can have detrimental implications on both physical and mental health. This includes a higher risk of stress-related illnesses like anxiety, depression, and heart disease.

in addition to triggering the fight or flight response, living in a major city can have a range of detrimental impacts on one’s physical and mental health. Chronic exposure to sensory overload can result in exhaustion, sleep disturbance, irritability, impaired cognitive performance, and even changes in brain structure and function (Clough, 2021).For instance, research in the journal Science Direct discovered that residing in a noisy urban environment can affect cognitive function and brain activity in the prefrontal cortex, a part of the brain linked to executive function and decision-making (Thompson et al., 2021).

Hence, it’s critical for people who live in big cities to be aware of the possibility of chronic stress and take action to manage it by using relaxation techniques such as participating in activities that enhance wellbeing.
