In the article Sweatology, many aspects of sweat are discussed. From body temperature regulation to medical consequences sweat proves itself to be more functional and necessary than I previously thought. Sweat is a process that comes from the excretory system, speciefically when "the skin stops losing heat to the air and absorbs it instead. Then temperaure-sensing nerves in the skin and he body's interior tell the brain to unleash a flow of swear for heavy-duty evaporation and cooling". Throughout Sweatology there are a lot of interesting facts. For example, as the early humans lost their fur sweat glands evolved. Also, the human body can tolerate overcooling but "we have little tolerance for even brief overheating". I found it interesting that "we run a little cooler in the morning, a little warmer in the late afternoon." Suprisingly this article also reveals that, wearing less clothes while out in the sun as an attempt to not sweat as much may be counterproductive due to the fact that unprotected skin takes in more heat. In relation to global warming, this article is optimistic that our system is "sturdy, adjustable and even reproducible by engineers working to make our future sweaty selves more comfortable". In regards to "adjustable" Sweatology claims that humans can develope "larger, more effecient sweat glands and slightly moister skin" as our planet heats up. Sweat also has a lot of medical consequences that are tied into it's system. If a body is overheated the brain malfunctions wuth six or seven degrees of fever and elderly people are more at risk for heat stroke because they sweat less "even if they are in good physical condition, and even if they become seriously overheated".

People have about 2-4 million and the bigger sweat glands= more sweat because they are more sensitive to nerve stimuli.

when does the brainsend a signal via the nerve? when nerves in the skin detect temperature they send a signal to the brain when the skin is to hot. When the skin is at a temperature in the 90's whether the heat source is internal or external...when muscles contract they generate heat. Heat is a waste of cellular respiration-or external like weather... a signal is sent to the brain to stimulate sweat

[|Research] done by Nina G. Jabolensky. [|Always Revealing, Human Skin Is an Anthropologist’s Map] Jabolsky's take on sweat is, "Absolutely. It’s often said that our large brains are what made it possible for us to evolve from ape to human. But those big brains could never have developed if we didn’t have exceptionally sweaty skin."
