“Thermoregulation is achieved by modulating physiological efferent functions (skin blood flow, sweating, shivering) and implementing behavioural strategies, following the central integration of thermal feedback from the deep body and superficial tissues.
“In all environments, cutaneous thermoreceptors provide the first thermal feedback signals, giving rise to thermal sensations, physiological adjustments and eventually to decisions relating to the pleasantness or comfort…
“The principal nerves carrying thermoreceptor feedback from the hand are the radial and median nerves, with the latter having a more important sensory role.”
