The World Health Organization (WHO) ranked physical inactivity as the fourth key risk factor that attributes to the global mortality rate, following hypertension, tobacco consumption and hyperglycemia as the three other factors that top the list. As such, the World Health Organization encourages everyone to engage in adequate physical activities. The Department of Health of Hong Kong’s Centre for Health Protection also encourages the public to engage in 30 minutes of moderate-intensity physical activities per day, for at least 5 days a week, as a way to improve the general public’s health and to reduce the risk of chronic diseases. The 30 minutes of physical activities can be performed once or divided into three 10-minute sessions.
Engaging in regular physical activities helps to improve our cardiopulmonary function and lower the risk of noncommunicable diseases, as well as reducing osteoporosis in women after menopause and improving psychological health.
