Body Temperature

Seriously explain why you think I'm wrong.
Or can't you?
Seriously, go away if you cant act right.
No, really seriously. Can you explain why you think I'm wrong?
At all?
Or are you going to persist in your dishonesty?
And I'd also like an explanation of why you think I am the one "not acting right" when you're the one that can't or won't explain.
I am not explaining anything to you, we are trying to have a nice discussion without being harassed. What were you raised by wolves?
I gave an answer, you declared I was wrong. I asked for an explanation.
Do you not have the simple courtesy to provide one?
Must you resort to insults and false accusation because of inability/ unwillingness to give a rational explanation?
Any further failure to provide an explanation, (which was asked for fairly politely) will result in me reporting you for trolling your own thread. Thank you.

Apparently John99 has elected to be reported rather provide an explanation. I, however, will give mine. (Just to see if he can find fault with it).
His question was:
So what would be the ideal ambient temperature to reach some equilibrium?
Since equilibrium is defined as the condition of a system in which competing influences are balanced and the discussion so far seems to have centred around heat loss from the body then, by default, the only condition that satisfies this is air at body temperature. Any cooler and we lose heat, any warmer and we gain. Admittedly we will start to overheat due to not radiating/evaporating body heat away anyway, but given John's apparent concern with body temperature not dropping over time, see posts 68 and 69, there seems to be no other answer to the (extremely-vaguely worded) question.
I think John realised this (or possibly not, it's hard to tell how [or if] his thought processes work) since he rephrased it (or changed altogether) in post 79.

through all of this NOBODY has mentioned the function of hormones
definition
1 : a product of living cells that circulates in body fluids or sap and produces a specific effect on the activity of cells remote from its point of origin; especially : one excerting a stimulatory effect on cellular activity
Trolling to you is asking anything relating to science but your harassment is not trolling?
You dont only do this to me because i have seen you do it too many people. I dont know why you get away with it.
You are ruining another science thread though.
Your body has an entire system devoted to regulating body temperature, hunger, and other internal conditions -- it's called the endocrine/neuroendocrine system. An area of the brain called the hypothalamus is in charge of regulating internal conditions such as body temp, hunger/satiety, thirst, emotional state, and your sleep cycle (circadian rhythm). Endocrine functions are achieved through the release of specific neurotransmitters, neuropeptides, and hormones that act at areas throughout your brain and other areas of the body.
The hypothalamus gland, located at the base of the brain, controls internal body temperature. This gland responds to sensory signals from temperature receptors in the skin and deep inside the body. The hypothalamus establishes a "set point" for the internal body temperature, then constantly compares this with its own actual temperature. If the two temperatures do not match, the hypothalamus activates temperature-decreasing or temperature-increasing procedures until the temperatures are equalized.
Body temperature regulation is then achieved through a variety of mechanisms including is sweating by the sudoriferous glands in the skin to cool the body, and muscle contraction which causes body temperature to rise.

I'm with yeah
sometimes Dywyddyr gets a big head
anyway I hope my recent posts helps
It was interesting, i just know a little about the hypothalamus. As a matter of fact i just read about it yesterday.
Seems like we thought the brain was responsible for those things you mentioned, or was this discovered earlier? Hypothalamus seems like a better candidate and it is actually part of the brain?
Perhaps the hypothalamus is similar to a BIOS and the brain is still the computer or rather CPU.
Moderator note: John99 has been permanently banned from sciforums.
John99 has been through the entire ban cycle. He continues to post idiotic nonsense as if it was science. He never attempts to back up his claims with evidence or argument.
He has been repeatedly warned. He has been repeatedly banned. None of this has produced any change in behaviour.
Goodbye John99.

hmm... good
my biology dictionary is old ( 1982 ) , although I got the quote online , just easier
yes the hypothalamus is part of which makes up the Brain
BIOS ?
can't remember what this acrinum stands for
explain
I think his whole point was to provoke and then play the victim - he won't be missed by me.
In computer-speak, BIOS= Basic Input Output System.
John99 did make a point about Dywyddyr that is valid. He tends to attack with his range of one liners and his evasive question with a question, under the pretense of being scientific, while rarely offering reasons that enhance the discussion. He tries to provoke others so they get blamed, with the staff not seeming to notice the antics of this Eddie Haskell. http://en.wikipedia.org/wiki/Eddie_Haskell
The staff needs to define the rules for science critics that are not based on a dual standard.
Back to the discussion, chemical reaction kinetics are effected by temperature but not always in a linear way. For example, endothermic reactions benefits by additional heat, while heat can become limiting for exothermic reactions. Heat can also be needed as part of the activation energy, such as rubbing sticks together until they get hot enough to start the fire. There are also molecular diffusion and viscosity issues which often benefits by some heat. Plus with life we are also dealing with water, which has some anomalous properties. If we balance it all, 98.6 F tends to be the sweet spot for the human body.
If we tweak temperature to below 98.6 and above 98.6, certain systems lose optimization while others improve. The result is an imbalance in terms of limiting reactions.
If you look at a cold blood critter, they need an external source of heat to get their cells warmed up for optimization. At cooler temperature, there is shift in kinetics more based on the needs of hybernation.
The human body makes use of the hypothalamus as part of the body's thermal control system. When we have a fever, the temperature set point can rise, favoring certain systems.

Wrong.
I ask questions for the purpose of getting an answer.
If someone doesn't know what they're talking about, e.g. John99, you, etc they evade.
False.
There isn't a "dual standard".
