according to nurse's 5-minute clinical consult: signs & symptoms diaphoresis is an autonomic nervous system response to physical or psychogenic stress and heart failure is one of the causes of this stress in the human body.

You must have a good understanding of receptor physiology to understand the core concepts of this question. Sweating occurs as a result of a sympathetic response. However, the exact answer is related to the receptors.

Sweat glands are special in that they are enervated by the sympathetic nervous system; however, these glands are activated by musacrinic receptors. While, muscarinic receptors are typically associated with a parasympathetic response, this is one situation where the rule of "there is always an exception" rings true.

...and....if you can't pump blood where it needs to go, and have to pump harder, and breathe harder, that's WORK...and might make you sweat a bit or more than a bit....

Anything that causes a sympathetic response can cause increased sweating.

Wow - there folks.

I was being all profound in thinking it is really just related to that fear of "dying" by not being able to breathe. Oh wait - I was on the right track.

You guys rock!

Chris - Glad your back in the USA!
