Increased Risk of Cardiovascular Diseases and Type 2 Diabetes
- Prolonged sitting is linked to a higher risk of cardiovascular diseases and type 2 diabetes, regardless of physical activity levels .
Premature Mortality
- Extended periods of sitting are associated with an increased risk of premature death from all causes, including heart disease and cancer .
Metabolic Health Issues
- Sitting for long durations negatively impacts metabolic health, leading to conditions such as obesity, impaired lipid metabolism, and metabolic syndrome .
Musculoskeletal Disorders
- Office workers who sit for prolonged periods report higher incidences of musculoskeletal disorders, particularly in the neck, lower back, and shoulders .
