Effects of repeated whole-body cold exposures on serum concentrations of growth hormone, thyrotropin, prolactin and thyroid hormones in healthy women.

What Was Tested

This randomized controlled trial looks at Exogenous HGH, sermorelin & older GHRPs (why they're passed over).

The aim of the present study was to examine the effects of two types of cold therapy, winter swimming in ice-cold water (WS) and whole body cryotherapy (WBC), on the serum levels of the growth hormone, prolactin, thyrotropin and free fractions of thyroid hormones (fT3, fT4).

Why It Was Studied

Cold therapy is used to relieve pain and inflammatory symptoms.

Humoral changes may account for the pain alleviation related to the cold exposures.

Who Took Part

PubMed tags the participants as women only.

How the Study Was Run

In design terms this was a randomized study.

The participants were allocated by chance, so the Exogenous HGH, sermorelin & older GHRPs (why they're passed over) group and the comparison group should start out alike.

What Was Measured

Blood samples used for the hormone measurements were taken on weeks 1, 4 and 12 before and 35 min after the cold exposures and on the days of the respective weeks, when the cold exposures were not performed.

Topics PubMed links to this paper include Adaptation, Physiological, Body Temperature, Cold Temperature, Cryotherapy, Growth Hormone, Prolactin and Thermosensing.

What This Means in Plain Language

The paper is a randomized study of Exogenous HGH, sermorelin & older GHRPs (why they're passed over).

The publication is from 2009 (Cryobiology), a journal based in Netherlands.
