Insensible perspiration is the continuous loss of body fluids through the skin in the form of sweat which is barely noticeable. Different synonyms for insensible perspiration include "invisible sweat", "unnoticeable sweat" or "latent sweating". Insensible perspiration is a critical process in regulating body temperature, as it works alongside other cooling mechanisms such as sweating. This process is essential, as it prevents the body from overheating, which can result in heat exhaustion or heat stroke in extreme cases. These synonyms for insensible perspiration can be used interchangeably, with each term describing the same physiological process of water loss through the skin.
