you would suffocate
letting air etc in makes nonsense of the idea of a closed system
the total amount of heat would rise at 1st  , then stabilize ( assuming the material doesnt absorb any heat from within the system )

but what you're really asking is what would the temperature be  ( 98.6 f is a measure of temp , not heat )
and it would rise ( both body temp and air temp ) until you die , and the metabolic reactions stopped( whether that be from lack of oxygen , or cell death )



there is no entropy of heat
heat would be generated ( as the expense of cell fuel ) , until death
once this happened , its a closed system , with no mechanism to transform the heat into work


Well entropy can cause heat, however, the idea of 'entropy of heat' is a little goofy.

EDIT: Which on a re-read is pretty much what you said.

My bad :P

If you were completely enveloped in a material barrier that let absolutely no heat in and no heat out would you burn, freeze, or stay at exactly 98.6 degree Fahrenheit? Could you survive inside this barrier provided you somehow had food, water, and air?


this scenario isnt possible in terms of "absolutely" no heat in/out since all matter conducts heat.

Aside from that, the scenario is almost contradictory. If youre able to breathe, you would release heat when you exhaled; and if you trapped that heat then you would have major pressure issues.

There will be heat exchange when you'll breathe and drink.

You would over heat, also your skin would become very dry and itchy. A Very Horrible and painful death...Do Not Try This At Home :P

also this

allowing the person to exhale would be a violation of your barrier, therefore the person would suffocate long before they overheated
if they were allowed to exhale, they would lose heat that way and maybe avoid overheating altogether

You would run out of oxygen before heat became an issue.

if its a closed system then where does the food/drink/air come from?

your body controls your core temperature but cannot stop heating itself completely. sweating, while helpful, only expells body-temperature mass, nothing hotter. even thinking produces heat. with NOWHERE to go it amplifies over time until you are deceased. then (assuming you decompose in your bubble) your rotting carcass continues to produce heat. i wonder if you could predict the temperature in the bubble after 2 years.
