One hour of physical activity daily may offset the risk of sitting at work.
About an hour of moderate-intensity activity (i.e. brisk walking) can erase the increased death rate associated with sitting at work all day. More than 1 million men and women were included in a meta-analysis which found when the least active participants (5 min. per day of moderate activity) sat all day their death rate increased by 27% compared to those sitting less than 4 hours daily. Yet, among the most active individuals (60-75 minutes of daily activity) prolonged sitting was not associated with increased death rates.
PositiveTip: If your job requires sitting all day, be sure to get at least one hour of moderate intensity activity daily.
