Demystifying Medicine Video

In the past few decades, our lifestyles have collectively shifted from ones that were physically demanding to ones that prevent very few physical challenges - this is known as a sedentary lifestyle. Due to the COVID-19 pandemic, we have also been required to adjust to a new normal of ‘social distancing’ and ‘sheltering in place’ which has further increased our sedentary behaviours. So while we are facing a viral pandemic, we are also facing the sedentarism pandemic.

This video outlines the characteristics of a sedentary lifestyle in the context of university students during a lockdown, the associated health risks and suggestions for how to reduce sedentary behaviours.
