Frequently asked questions

Why is oxytocin called the 'love hormone'?
It surges during bonding moments like hugging, intimacy, and parent-child contact, promoting feelings of trust and attachment.
What does oxytocin do in childbirth?
It drives the contractions of labor and later triggers the 'let-down' reflex that releases milk during breastfeeding.
Can oxytocin be negative?
Its effects depend on context — it can deepen trust within a group while sharpening wariness of outsiders, so it is not purely a 'feel-good' chemical.
