How can a sedentary lifestyle be defined?
Physical inactivity and a sedentary lifestyle are different, but both are to be avoided.
A sedentary lifestyle is defined as low energy expenditure as a result of prolonged sitting or lying down: working seated, watching television, car journeys, etc. Quite simply, it corresponds to the time spent sitting or lying down per day.
If you spend over 7 hours per day in a seated or lying down position (excluding time spent sleeping), you are considered to be sedentary. Oh dear, it mounts up quickly, doesn't it?
Ordinary back pain can be a sign of a sedentary lifestyle. Feel free to discuss it with your doctor. Generally speaking, symptoms appear gradually, and we don't notice them easily.
