Hair cortisol concentration differs across site and person: localisation and consistency of responses to a brief pain stressor

Sharpley, C. F. and Kauter, K. G. and McFarlane, J. R. (2010) Hair cortisol concentration differs across site and person: localisation and consistency of responses to a brief pain stressor. Physiological Research, 59 (6). pp. 979-983. ISSN 0862-8408

Abstract

Although in vitro studies have shown that cortisol concentrations in human and animal hair respond to environmental stressors, few data have been reported regarding the in vivo variability of hair cortisol to brief pain stressors. As an extension of a previous study, hair was collected and assayed for cortisol concentrations from each of three sites (elbow, mid-forearm, wrist) before and after participants immersed their hand in ice water for 1 min. Results showed that the 'localization' boundary of hair cortisol responses previously reported was able to be reduced to only 250 mm between sites. Furthermore, all participants showed considerable variability in hair cortisol across the three sites at each collection period, although consistency across participants in overall responsivity of hair cortisol to the pain stressor was observed.
