Fifteen healthy adults (8 men, 7 women) volunteered. Applications of heat and cold were achieved through water immersions in two tanks maintained at 42 and 12 degrees C water temperature, respectively, in an A-B-A-B fashion. Throughout the experiment, the participants&#8217; right hand up to the ulnar styloid process was placed inside a temperature-controlled box set at 0 degrees C air temperature.<\/p>\n<p>Results demonstrated that cold-induced vasodilation occurred only during condition B and at times when body heat content was decreasing but rectal temperature had not yet dropped to baseline levels.\u00a0Following the occurrence of all cold-induced vasodilation events, rectal temperature was reduced, and the phenomenon ceased when rectal temperature fell below baseline. Heart rate variability data obtained before and during cold-induced vasodilation demonstrated a shift of autonomic interaction toward parasympathetic dominance, which, however, was attributed to a sympathetic withdrawal. Receiver operating characteristics curve analyses demonstrated that the cold-induced vasodilation onset cutoff points for rectal temperature change and finger temperature were 0.62 and 16.76 degrees C, respectively.<\/p>\n<p>It is concluded that cold-induced vasodilation is a centrally originating phenomenon caused by sympathetic vasoconstrictor withdrawal. It is dependent on excess heat, and it may be triggered by excess heat with the purpose of preserving thermal balance.<\/p>\n<p><span style=\"color: #000000;\"><strong>Full Text Link: <\/strong><\/span><\/p>\n<p><a href=\"https:\/\/journals.physiology.org\/doi\/full\/10.1152\/japplphysiol.91426.2008\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/journals.physiology.org\/doi\/full\/10.1152\/japplphysiol.91426.2008<\/a><\/p>\n<p><span style=\"color: #000000;\"><strong>Download PDF:<\/strong><\/span><\/p>\n<p><a href=\"https:\/\/www.famelab.gr\/wp-content\/uploads\/2022\/04\/Influence-of-thermal-balance-on-cold-induced-vasodilation_2009.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/www.famelab.gr\/wp-content\/uploads\/2022\/04\/Influence-of-thermal-balance-on-cold-induced-vasodilation_2009.pdf<\/a><\/p>\n<p><img decoding=\"async\" class=\"alignnone wp-image-8302 size-full\" src=\"https:\/\/www.famelab.gr\/wp-content\/uploads\/2021\/11\/Line.png\" alt=\"\" width=\"1316\" height=\"1\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>Flouris AD, Cheung SS.
