Lack of physical activity is one of the major risk factors for heart diseases, cerebrovascular disease, diabetes mellitus, hypertension, some types of cancers and obesity.
Situation in Hong Kong
Most people in Hong Kong adopt a sedentary life style. The Behavioural Risk Factor Survey conducted in April 2016 revealed that more than a quarter (28.0%) of adult aged 18 - 64 had not done any moderate or vigorous physical activity for at least 10 minutes at a time and only less than half (44.6%) had done some vigorous physical activity during the week before enumeration.
Duration and intensity of physical activity for good health
Physical activity need not be strenuous to be beneficial. 30 minutes of physical activity of moderate intensity a day on at least 5 days a week is good enough to provide health benefits and reduce the risk of certain chronic diseases. You may not need to do it in one single session but divide the 30-minute physical activity time into three 10-minute sessions.
