[1] A person living a sedentary lifestyle is often sitting or lying down while engaged in an activity like socializing, watching TV, playing video games, reading or using a mobile phone or computer for much of the day.
This diminished blood flow leads to reduced oxygen delivery to the brain (cerebral hypoxia), impairing cognitive functions such as concentration and alertness.
Such forward head posture puts excessive strain on the cervical vertebrae, leading to muscle tension and pain in the neck and shoulders.
Over time, this can cause the cervical vertebrae to become misaligned permanently, leading to chronic neck pain and potential nerve impingement.
Additionally, collagen, a primary structural protein in tendons and ligaments, tends to harden when not regularly stretched and mobilized, which leads to decreased flexibility and increased risk of injury in the back.
These deposits can adhere to the vessel walls, forming plaques (atherosclerosis), which eventually narrow the arteries and restrict blood flow.
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.
[3] 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.
[46][47] Recent innovations in AI technology have led to the development of exercise prescription systems designed to reduce sedentary behavior.
[48] Some evidence has been found of a negative association between exposure to an existing urban motorway and moderate to vigorous physical activity.
[52] 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.
[58] Despite this knowledge and due in part to an increase in sedentary behaviors, as of 2018 children have 8 fewer hours of free play each week than they did 20 years before.
[59] Several studies have examined the effects of adding height-adjustable standing desks to classrooms, which have reduced the time spent sitting.
study, interventions reduced the amount of time children spent sitting in the classroom, which was associated with lower body mass index and waist circumference.
