Prolonged periods of sitting are linked to increased health risks, even for individuals who engage in daily exercise, according to data from the Mayo Clinic and the World Health Organization (WHO). Research indicates that extended sedentary time reduces energy expenditure and is associated with obesity, elevated blood pressure, high glucose and cholesterol levels and increased abdominal fat accumulation.
The health consequences extend to a heightened risk of death from cardiovascular diseases and cancer. An analysis of 13 studies, encompassing over one million participants, revealed that individuals who remain seated for more than eight hours daily without physical activity face a mortality risk comparable to that associated with obesity and smoking.
While the study indicated that 60 to 75 minutes of moderate-intensity aerobic physical activity per day can mitigate the effects of prolonged sitting, other research suggests that sedentary behavior continues to impact health even in active individuals. The WHO defines physical activity as any bodily movement that requires energy expenditure, emphasizing its role in preventing non-communicable diseases such as cardiovascular disease, cancer, and diabetes, as well as improving mental and brain health.
However, physical inactivity and sedentary habits remain significant risk factors. The WHO reports that individuals with insufficient physical activity have a 20% to 30% higher risk of mortality compared to those who meet recommended activity levels. Sedentary behavior, characterized by low-energy expenditure while seated or reclining, is linked to increased mortality from all causes, cardiovascular disease, cancer, and type 2 diabetes in adults.
Globally, 31% of adults and 80% of adolescents do not meet recommended levels of physical activity. Estimates suggest that physical inactivity could generate healthcare costs nearing $300 billion between 2020 and 2030. A report from the American Heart Association highlights growing evidence linking sedentary behavior to increased cardiovascular morbidity and mortality in adults.
The Mayo Clinic suggests several adjustments to daily routines to reduce sedentary time. These include standing while on phone calls or watching television, utilizing a standing desk for portions of the workday, conducting walking meetings, and adapting workspaces to encourage movement, such as incorporating a treadmill with a computer support. Taking breaks every 30 minutes to stand or move is likewise recommended.
In Argentina, a move towards a more transparent and preventative healthcare model is underway, according to Argentina.gob.ar, though the direct connection to addressing sedentary lifestyles remains unspecified.
