Sitting time is a common measure of a sedentary lifestyle. A global review representing 47% of the global adult population found that the average person sits down for 4.7 to 6.5 hours a day with the average going up every year.[7][8][9][specify] The CDC found that 25.3% of all American adults are physically inactive.[10]
Screen time is a term for the amount of time a person spends looking at a screen such as a television, computer monitor, or mobile device. Excessive screen time is linked to negative health consequences.[11][12][13][14][15][16][17][6][excessive citations]
