Love, and the affection that flows from it, regulates the body's stress system - the circuit of peptides, hormones, and pathways between the mind and body that keeps us wound up tight or calmly centered - and manages all other systems from the immune to the endocrine. Love and affection balance the stress system and help maintain health. With the hard science to support its physical benefits, learn how affection, self-nurturance, and altruistic works improve health, create an inner stillness, and enable the neurobiology of love to bring the body and mind into a state of flow and resilience.
