lead to decreased productivity and increased absenteeism from necessary activities like work. A sedentary lifestyle contributes to or can be a risk factor for: Anxiety Cardiovascular disease Migraines Breast cancer Colon cancer Computer vision syndrome (only from excessive electronic use) Depression Diabetes Gout High blood pressure Lipid disorders Skin problems such as hair loss Mortality in adults Obesity Osteoporosis Scoliosis Spinal disc herniation (low back pain) Weight gain Prevention Adults and children spend long amounts of time sitting in a workplace or at a school, which is why interventions have been focused in these two areas. Mass media campaigns might also be able to reduce the amount of time spent sitting or lying down and positively affect the intention to be active physically. In urban spaces Some evidence has been found of a negative association between exposure to an existing urban motorway and moderate to vigorous physical activity. The proportion of physically active individuals was higher in high- versus low-walkability neighborhoods. Rising rates of overweight, obesity, and physical inactivity in China's rapidly growing cities and urban populations have been due to urban development practices and policies. In a work environment Occupational sedentary behaviour accounts for a significant proportion of sitting time for many adults. Some workplaces have implemented exercise classes at lunch, walking challenges among coworkers, or allowing employees to stand rather than sit at their desks during work. Workplace interventions such as alternative activity workstations, sit-stand desks, and promotion of stair use are among measures implemented to counter the harms of a sedentary workplace. A 2018 Cochrane review concluded that "At present there is low‐quality evidence that sit‐stand desks may reduce sitting at work in the first year of their use. However, the effects are likely to reduce with time. There is generally insufficient evidence to draw conclusions about such effects for other types of interventions and for the effectiveness of reducing workplace sitting over periods longer than one year." In education The majority of time children are in a classroom, they are seated (60% of the time). Children who regularly engage in physical activity are more likely to become healthy adults; children benefit both physically and mentally when they replace sedentary behavior with active behavior. Despite this knowledge and due in part to an increase in sedentary behaviors, children have 8 fewer hours of free play each week than they did 20 years ago. Several studies have examined
