Affection Deprivation Is Associated With Physical Pain and Poor Sleep Quality

Social bonds are necessary for human survival and affectionate communication is paramount for their formation and maintenance. Consequently, affection deprivation—the condition of receiving less affectionate communication than desired—is associated with social pain, and contemporary research indicates that social pain has substantial neurological overlap with physical pain. Thus, it was proposed that affection deprivation would be associated with the sensation of physical pain as well as with poor-quality sleep. Three studies involving a total of 1,368 adults from nearly all U.S. states and several foreign countries revealed significant associations between affection deprivation, physical pain, and multiple facets of disturbed sleep.
