Cultural Stress: The Ubiquitous Stressor Hiding in Plain Sight.

Howard Murad

Adv Mind Body Med 2021 Spring;35(2):14-16

While most healthcare providers are generally aware of the role stress plays in disease development, few are attuned to a phenomenon I call "Cultural Stress," which compounds all of life's other stressors. Cultural Stress is the constant, pervasive, ever-increasing stress of modern living. It includes overexposure to technology at the expense of in-person relationships; 24-hour connectivity, which blurs the boundaries between work and personal life; on-demand delivery of goods and services, which severs neighborhood and community relationships and results in long sedentary hours in front of our screens; the pace of technological change, which contributes to professional, economic, and social insecurity; our global economic system, which sows uncertainty as it outsources jobs overseas or to new technologies; environmental contaminants, noise, crowding, and various new sources of radiation; changes to our diet, which has become heavily reliant on a few processed commodities (corn, wheat, sugar, and soy); and changes to our urban development and transportation patterns, which result in less physical activity and more hours spent sitting in long commutes.
