Research indicates that excessive TV watching can adversely affect aging, as it typically promotes a sedentary lifestyle. This decrease in physical activity and potential impact on cognitive function can lower the likelihood of aging healthily.
A study suggests that watching TV for over two hours daily may decrease the likelihood of aging healthily. The research involved surveying 45,000 female nurses who were 50 years of age or older in 1992 and free from chronic illnesses. It asked about their sedentary and active behavior at home and work, as well as their general well-being.
The researchers then conducted a 20-year follow-up, collecting data on individuals’ sitting time at work and home, including television viewing, as well as their hours spent standing or walking at home and work. This data was then analyzed in relation to their aging process.
The study revealed that watching TV accounted for the most significant portion of sitting time among the participants, often for extended durations. It indicated that every additional 2 hours spent sitting and watching TV was linked to a 12% reduction in the likelihood of healthy aging. Conversely, increasing moderate physical activity at work by 2 hours led to a 6% improvement in the chances of aging healthily.
Sitting in front of the TV typically involves various associated behaviors, such as consuming junk food and prepackaged meals, lack of social interaction, and disruptions to sleep patterns. These accompanying activities can compound the negative impacts of extended television viewing.
A practical approach might be to combine TV viewing with healthy habits, such as staying active or snacking on nutritious foods while watching. Alternatively, substituting TV time with light exercise, more intense physical activity, or additional sleep could also contribute positively to maintaining good health as you age.
