Social support from relationships is important for health and well-being. There are four main types of social support: instrumental, emotional, informational, and appraisal. Social support reduces mortality, provides health benefits through touch, and helps alleviate loneliness. Close friendships that allow for confiding can also buffer stress. Maintaining and enriching social connections, such as with friends and pets, is important for health, especially during times of loss or divorce when support networks are weakened.
