New Delhi, Feb 21 (ANI): A new study now finds scientists saying that variety in social circle may help a person live longer. Researchers at The University of Texas at Austin have found that older adults who spend more time interacting with a wide range of people were more likely to be physically active and had greater emotional well-being. In a paper out today in the Journals of Gerontology Series B: Psychological Sciences and Social Sciences, researchers found that study participants who interacted more with family members and close friends, as well as acquaintances, casual friends, service providers and strangers were more likely to have higher levels of physical activity, less time spent sitting or lying around, greater positive moods and fewer negative feelings. It is the first study to link social engagement with physical activity throughout the day. The researchers asked study participants about their activities and social encounters every three hours for about a week. Participants also wore electronic devices to monitor their physical activity. Fingerman and the team observed that during the three-hour periods when participants were engaging with a greater variety of social partners, they reported engaging in a greater variety of activities such as leaving the house, walking, talking with others, or shopping. They also engaged in more objectively measured physical activity, and less time being sedentary. This study showed those acquaintances or peripheral ties may encourage older adults to be more physically active, a key factor that has been shown to contribute to physical and emotional health, as well as cognitive ability.
