A recent report from the Phoenix Center for Advanced Legal & Economic Public Policy Studies found that social media and Internet usage have the potential to reduce depression levels in senior citizens by 20%–and hence trim the nation’s health care costs.

“Maintaining relationships with friends and family at a time in life when mobility becomes increasingly limited is challenging for the elderly,” says Dr. Sherry G. Ford, a co-author of the study and an associate professor of communication studies at University of Montevallo in Alabama. “Increased Internet access and use by senior citizens enables them to connect with sources of social support when face-to-face interaction becomes more difficult.”
