How to promote social connection



There are plenty of ways to improve social connectedness. According to the CDC, small acts can make a big difference.







We can do simple things like reaching out and checking on one another. There is power in a simple check-in with a friend to let them know you're thinking about them. Even though no official guidelines exist, here is a list of some suggestions.

Commit to Connect is an initiative launched by the U.S. Administration for Community Living to fight social isolation and loneliness by helping people connect and engage to build the social connections they need to thrive.

The AARP Foundation's Connect2Affect invites anyone who may be impacted by social isolation to take a 3-minute assessment to better understand their risk level. At the end of the assessment, helpful information and local recommendations will be provided based on your results.

Local groups and nonprofit organizations are also getting involved in creating environments that foster social connections. Additionally, nursing homes and assisted living communities, grocery stores, doctors' offices and community groups can foster community connectedness.
