SUPPORTED
the evidence backs this
confidence 90/100
Multiple studies demonstrate that specific neurological, neuroendocrine, and neuroanatomical mechanisms—including limbic system dysfunction, opioid receptor alterations, and HPA axis dysregulation—underlie the feelings and states associated with loneliness.
