Boston, MA – Swapping out sedentary activities like sitting in front of the TV for physical activity is linked to better chances of healthy aging, a recent study reveals. Researchers from Harvard’s T.H. Chan School of Public Health found that replacing TV time with light physical activity, exercise, and adequate sleep can contribute to healthier aging outcomes.
The study, published in JAMA Network Open, involved analyzing data from over 45,000 individuals aged 50 or older who were free of chronic diseases in 1992. The researchers tracked the participants for 20 years, monitoring their sedentary behaviors like watching TV and their engagement in physical activities at work and home.
Healthy aging was defined as living to at least 70 years old while maintaining several key health indicators, including no major chronic diseases and no impairments in memory, physical health, and mental health. The study found that for every two hours spent watching TV, there was a 12% decrease in the likelihood of aging in a healthy manner. Conversely, adding two hours of light physical activity at work led to a 6% increase in the odds of healthy aging.
Dr. Andrew Freeman, director of cardiovascular prevention and wellness at National Jewish Health in Denver, emphasized the importance of reducing sedentary behaviors, as prolonged sitting has been associated with negative health outcomes. He suggested incorporating more movement into daily routines, such as using standing desks or engaging in walking meetings, to combat the adverse effects of prolonged sitting.
Additionally, Freeman highlighted the correlation between sedentary behaviors in childhood and increased risk of heart disease later in life. These unhealthy habits, often accompanied by poor dietary choices and lack of social interaction, can have detrimental effects on overall health and well-being.
In conclusion, Freeman recommended finding a balance between sedentary activities like watching TV and engaging in physical movement. Setting limits on screen time, incorporating healthy snacks, and leveraging technology tools to monitor activity levels can help individuals maintain a healthy and active lifestyle as they age. By making small changes to reduce sedentary time, individuals can improve their chances of aging in a healthier and more vibrant manner.
