Replacing sedentary behavior with physical activity (isotemporal substitution) improves HRQoL, with light physical activity being sufficient for most dimensions of quality of life.
You can improve your quality of life by swapping sitting time for movement, without needing extra time. Replacing just one hour of sitting with one hour of light activity (like walking or gardening) daily leads to significant improvements in physical function, pain, and mental health. You do not need to do vigorous exercise to get these benefits.
Replacing one hour/day spent seated by one hour/day performing light physical activity in 2003 was associated higher scores on the SF-36 scales in 2009. The association was clinically relevant (regression coefficients > 3) and statistically significant (p < 0.05) for the scales of physical functioning, physical role, bodily pain, vitality, social functioning and emotional role.
Why this rating
