Sedentary behaviour, like sitting or lying down, involves very little energy expenditure. It severely limits the calories you burn, and the modern lifestyle is mostly sedentary. Most people spend more time on their backside than on their feet. All this sitting with little or no exercise is doing a lot of harm to the body and can affect the health negatively. Basically, sitting is a normal human body posture; and when people work, socialise, study or travel, they often do so in a seated position.
Over half of the average person’s day is spent sitting; doing things like driving, working at a desk or watching television.
Your everyday non-exercise activities, like standing, walking and even fidgeting, still burn calories. Sitting too much encourages weight gain.
When it comes to weight management, the fewer calories you burn, the more likely you are to gain weight.
This is why sedentary behaviour is so closely linked to obesity. In fact, research shows that obese individuals sit for an average of two hours longer each day than lean people do.
