It is when you feel like you belong and have the support and care that you need.

How it works Creating social connections People are social creatures by nature. Our relationships with family, friends, coworkers, and community members are important to our survival. Stable and supportive relationships give us the support we need to cope with stressful life challenges. People with healthy relationships are more likely to make healthy choices that lead to better mental and physical health. Social connections give us:
* Emotional support: people we can turn to during good times and hard times.
* Physical support:
* A ride to the doctor or grocery store.
* Help with childcare on short notice.
Community connections Communities that offer supportive connections are just as important. They can help create trust and resilience among community members in public places, such as:
* Neighborhoods.
* Schools.
* Places of worship.
* Workplaces.
* Parks and recreation centers.
Having safe access to public areas for people to connect encourages: * Connections among people in the community. * Less social isolation and loneliness. * Community members to give back, further strengthening the bonds.
