A group of Australian studies has shown that lack of physical activity causes more cardiovascular disease in women over 30 than obesity, hypertension, or smoking. The study was recently published in the BJSM by Australian academic Dr. Wendy J. Brown, who noted that measures to increase and maintain physical activity are more beneficial for improving public health, especially for women. Previously, a study listed the top 10 causative factors worldwide, with hypertension at the top of the list, followed by smoking. Smoking leads to a high incidence of cardiovascular disease as the primary factor, smoking 2 to 4 cigarettes a day than never smokers are 50% more likely to suffer a heart attack, smoking 20 to 40 cigarettes will suffer an 8-fold increase in the probability of heart attack, “never smokers live an average of ten years longer than smokers, quit smoking within a year the incidence of myocardial infarction can be reduced by about 30%.” In addition to the control of smoking, experts also said that bad habits and lack of exercise is also an important reason for the high incidence of cardiovascular disease. Now many young people are advocating the concept of “stay at home”, shopping and watching movies can be done online, and even meals can be ordered for delivery, greatly reducing the normal exercise time. It is best to have 100 minutes a day, 100 steps per minute frequency of walking, or 30 minutes of brisk walking or 15 minutes of running to replace.
