Why it is important
People with strong social relationships live longer. Connections and interactions with close others promote health through shaping daily health behavior choices. Having close friends may promote brain health as we age. Social contact is one of the most important drivers of subjective well-being. A strong support system will help you manage stress. Social support is associated with increased psychological well-being and increased resilience during important life events. In stressful times, social support helps people reduce psychological distress (e.g., anxiety or depression). People having strong relationships are half as likely to catch a common cold. Lack of social connections can increase your chances of becoming sick through immune system dysregulation. Loneliness can also increase levels of depression, pain, and fatigue. Loneliness accelerates the rate of physiological decline. Studies consistently show increased risk of death among persons with a low quantity, and sometimes low quality, of social relationships. Experimental studies of humans and animals suggest that social isolation is a major risk factor for mortality from widely varying causes.
