Exercise and physical activity are crucial for healthy ageing , as research shows that even light activities like housework can improve one 's odds of reaching 70 free of mental health issues , memory problems , physical impairments , and chronic diseases . The latest findings from the Nurses Health Study , conducted over 20 years by Harvard T.H. Chan School of Public Health and other institutions , indicate that every two hours of daily TV watching reduces the chance of healthy ageing by 12 percent , while two hours of light physical activity can increase it by 6 percent.
The impact of technology and sedentary behaviors on healthy ageing is a growing concern , with prolonged TV watching linked to negative health outcomes . Excessive sitting has been shown to impair skeletal muscle function , disrupt sugar and fat metabolism , and reduce insulin sensitivity , affecting overall health . Research suggests that any light physical activity , such as housework , can positively impact various aspects of health and improve the odds of healthy ageing without the need for high - intensity exercise plans.
The study underscores the importance of reducing sedentary behaviors and increasing physical activities to promote healthy ageing . Public health campaigns should focus on encouraging light physical activities and decreasing prolonged TV watching to improve overall health outcomes in older populations . With the support of grants from the National Institutes of Health , ongoing research aims to raise awareness about the benefits of exercise and physical activity in maintaining health and functionality as individuals age.
