How wild is this??
Here’s the process:
Newborns are born coated in a mix of amniotic fluid, vernix caseosa, and active sweat glands, creating a highly specific, unique chemical signature on their heads.
When a mum pulls her baby close and takes a deep sniff, those scent molecules hit her olfactory system and travel straight to her limbic system (the emotional center of the brain).
This instantly cues the posterior pituitary gland to flood her body with oxytocin - the “love hormone.”
That massive hormonal surge then tells the uterus to contract hard. These contractions are what shear the placenta away from the uterine wall and safely compress open blood vessels to prevent postpartum hemorrhage.
At the same time, the scent activates the dopamine reward pathway (the same area that lights up with delicious food), delivering a rush of natural euphoria and pain relief exactly when a new mother needs it most.
Nature really thought of everything. 🤍
