Effects of Massage Versus Rest on Hormones

Investigating the Effects of Massage vs. Rest on Oxytocin, ACTH, and B-endorphins

This study will investigate the effects of 15 minutes of massage compared to 15 minutes of quiet rest on physiological variables. Specifically, the investigators will measure the effects on levels of the social hormone oxytocin, and on other physiological variables that interact with oxytocin or that may be influenced by massage (including ACTH, Beta-endorphin, and IL-1alpha). The investigators will also investigate whether, in the case of hormones changes, these influence social decision making.

Interested participants will have the experiment explained both verbally and in writing, and asked to give their informed consent in writing. After consent, the participants will be led to a private room for their first 30ml blood draw by a qualified phlebotomist. Participants will then have a second 30ml blood draw.
