Maximum temp possible with a constant heat source?

Click For Summary

Discussion Overview

The discussion revolves around the maximum temperature achievable in a confined space with a constant heat source, specifically focusing on human bodies as the primary source of heat and the effects of humidity on perceived temperature. The conversation explores the relationship between body temperature, environmental conditions, and heat dissipation mechanisms.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that the perceived heat in a crowded room is primarily due to high humidity rather than actual temperature, arguing that the air temperature cannot exceed the temperature of the human body.
  • Another participant agrees with the initial reasoning, stating there are no flaws in the logic presented.
  • A different viewpoint is introduced, questioning whether insulation (like wearing a heavy jacket) could prevent the body from dissipating heat effectively, potentially leading to an increase in body temperature.
  • One participant asserts that if the body cannot cool itself, the temperature could rise above 100F, with a maximum threshold of around 105F before critical health risks arise.
  • It is noted that in a perfectly insulated environment, individuals might lose consciousness before the room temperature reaches 100F.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between body temperature and environmental temperature, with some agreeing on the initial reasoning while others challenge it by introducing scenarios involving insulation and heat dissipation.

Contextual Notes

The discussion includes assumptions about heat dissipation and the effects of humidity, which may not be fully explored or defined. The potential impact of insulation on body temperature regulation is also a point of contention that remains unresolved.

About a month ago I went to a show in a rather small basement room. I've been there several times and it is usually very hot in there with all the people packed in. You will sweat profusely simply standing there. This last time I was with some people who hadn't been there before and found the heat quite surprising. Later though, I began to think about the situation and it seemed to me that the temperature couldn't have been that high. Rather, it was the 100% humidity that made it seem so hot. Upon explaining this idea they expressed doubt that the temperature wasn't above 100F.

My logic is this. The main source of heat is human bodies. The human body couldn't sustain a temperature significantly above 100F for a long period of time. It is impossible for the surrounding air temperature to rise above the source of the heat.

Can anyone see any flaws in that reasoning?

Yup.

Unless some idiot left the heating on...
Take a thermometer next time.
 
I think I disagree in this.
If you wear a big jacket designed for really cold weather, but you're in your living room at 25C, according to what your thoughts are, the temperature of your body won't raise. The cells produce heat, which needs to be dissipated in order to maintain the body at its normal temp. But being very insulated keeps you from dissipating the heat, and your body starts to sweat to dissipate more heat, but shouldn't there be a point that even sweating a lot woulnd't be enough to maintain the temperature?
 
Yes, your body temperature will rise above 100F if it can't adequately cool itself. The highest it can go is about 105F before you die. Even if the room was perfectly insulated, people would be passing out before the temperature of the room got above 100F.
