The early phase of love represents an extreme neurobiological state somewhat contradictory in a physiologic sense from subsequent phases and states. Stress appears to be the trigger for a quest for pleasure, proximity, and closeness. As a norm, moderate stress encourages social interaction.
Within a homeostatic range, stress-related physiologic processes including the hormones of the hypothalamo-pituitary adrenal axis can help develop and promote social bonding. Indeed, some of the signs commonly associated with love-anxiety palpitations increased peristalsis are manifestations of the stress response (albeit in a pleasurable way). Indeed, subjects in love show higher levels of cortisol when compared to controls. Irrespective https://kissbrides.com/fi/blogi/ruotsinkieliset-treffisivustot-ja-sovellukset/, this stress response appears to be important in the formation of social contact and attachment.
This “love induced hypercortisolemia” may represent a nonspecific stress response to change that characterizes early phases of relationships or a physiologic state of alertness that may help overcome neophobia
Central norepinephrine may also be involved. Increased activity of norepinephrine generally produces alertness energy sleeplessness and loss of appetite, increased attention, and increased memory for new stimuli which characterize (the earlier) phases of human love. Norepinephrine is also associated with peripheral sympathetic nervous systems including increased heart rate, sweating trembling which may explain this experience in love.
Positive social interactions and pair bonding (see below) appear to alleviate stress through oxytocin (OT) facilitating security and support. It appears therefore that initial anxiety and stress is an inherent component of early love which reaches its fulfillment through “the chill” rendered by love and deep relationships. These appear to be mediated by a complex interaction between pathways that link stress response to reward mechanisms.Leggi tutto
