Hi Kirsten,
I also think the mechanism could be via decreased stress in response to
oxytocin release?? at least partially??
I talk one of my papers about how oxytocin release can happen in mums due to
skin to skin contact and my refs for this are
Matthiesen A, Ransjo-Arvidson A, Nissen E, Uvnas-Moberg K: Postpartum
maternal oxytocin release by newborns: effects of infant hand massage and
sucking. Birth 2001, 28:13-19.
32. Uvnas-Moberg K: Oxytocin may mediate the benefits of positive social
interaction and emotions. Psychoneuroendocrinology 1998, 23:819-835.
I haven't had time to look in them to work ouyt which says this but from
memory it was talkeda bout as being something that everyone knows (ie not
something new). I also found suggestions here and there that oxtocin would
be released in both mother and child response to the social interactions bet
mothem....I like to tell the story of an adoptive mum I know who was
carrying her 2 day placed toddler daughter in a sling going for a walk and
started experiencing vagina contractions.....oxytocin says I, how wonderful!

Subject: oxytocin increased by skin-to-skin alone?
I have a student who is asking me about the mechanism of benefit for
skin-to-skin. I have
a feeling that increased oxytocin levels in both mom and baby are
responsible for a lot
of the physiological stabilization, as well as the increase in feeding
behaviors and
maternal behavior. However, I can't come up with 1) a mechanism for
how this would work
in things like heart rate and breathing, and 2) evidence for the fact
that oxytocin is
increased by skin contact (without necessarily breastfeeding). I know
that it must be, but if anyone has evidence for this,
or a reference, I would greatly appreciate it.
I imagine the effects on physiological stabilization must be through
the mechanism of
inhibition of stress responses (cortisol) and the sympathetic nervous
system, but I'm
missing a real link to skin-to-skin and also lacking clarity on
mechanisms involved.
Thanks for any help to this incorrigible physiology geek!
