Spend many hours sitting in a day? At the office or working from home, when driving or riding, in front of the television relaxing etc. Chances are you’re probably sitting while reading this.
Death by sitting
In a study* that compares adults who sat longer, it was discovered:
Adults who spend
less than 2hrs a day sitting in front of the TV or other screen-based entertainment,
faced 50 per cent increased risks of death from any cause.
Adults who spend
more than 4hrs a day sitting to enjoy recreational screen time,
faced 125 per cent increased risks of heart attack, chest pain or similar ailment.
“While a brief period of sitting here and there is natural, sitting for long periods of time can seriously impact your health, with research showing that having inadequate physical activity can cause a host of health risks,” shares Dr Bernice Liu, Principal Physiotherapist,

Sedentary lifestyle is the new epidemic
Leading a sedentary lifestyle (lack of physical inactivity) has been identified as the fourth leading risk factor for global deaths, causing approximately 3.2 million deaths each year.
In fact, according to the WHO (World Health Organisation), 1 in 4 adults globally is not active enough and more than 80% of the world’s young population – from both developed and developing countries – lead sedentary lifestyles.
In Singapore, a health survey showed that only 19 per cent of adults aged 18 to 69 years old exercise regularly and more than half of people in Singapore do not exercise during their leisure time.
Increasing number of young Singaporeans are getting liver disease despite drinking less alcohol, why?
Moving yet still sedentary
Sedentary behaviour is defined as the time spent in activities involving low levels of energy expenditure (1.0 to 1.5 metabolic equivalent tasks (METS) such as sitting, watching television, and driving).
On the other hand, physical activity refers to any activity that results in your heart beating faster and breathing becomes quicker and it can be categorised into light, moderate and vigorous intensity.
Thus, one can be physically active and meet the guidelines, but still considered to be sedentary if they spend a significant part of the day sitting or lying down. Both being physically active and limiting the time spent sedentary are essential for one's wellbeing.
Sitting too much and its risks
Health risks associated with a sedentary lifestyle include:
- Increased risk of heart disease and stroke, diabetes and obesity, high blood pressure, cancer and depression
- Poor posture and slouching, neck and back pain, osteoporosis, and increased predisposition to falls and injury
If one spends a majority of their waking hours sedentary, exercising for just an hour once in a while is not going to negate the effects of prolonged sitting.
