Physical inactivity, often termed as a "silent pandemic," is a global health concern with far-reaching consequences. It refers to a level of physical activity that is much lower than the minimum amount recommended for maintaining good health. The World Health Organization (WHO) recommends that adults aged 18–64 should engage in at least 150 minutes of moderate-intensity aerobic physical activity, or 75 minutes of vigorous-intensity activity, throughout the week. However, a significant portion of the global population fails to meet these guidelines, leading to numerous health issues.
The repercussions of physical inactivity extend beyond the well-documented risk of developing chronic diseases such as heart disease, type 2diabetes, and certain types of cancer. It also contributes to an increased incidence of mental health problems, including depression and anxiety. Furthermore, physical inactivity is a key risk factor for obesity, which in turn exacerbates the risk of other diseases and complicates management of existing health conditions.
Economically, the burden of physical inactivity is substantial, leading to increased healthcare costs and lost productivity. It affects individuals of all ages and backgrounds, making it a universal issue. The sedentary nature of modern work, increased screen time, urbanization, and a lack of safe spaces for physical activity in many communities are among the factors contributing to this global challenge.
