Inside needs a constant temp of 98. Outside has ways of cooling off (sweat) or heating up (shivering) our outside doesn’t need a constant tempature but the inside does. Ofcourse we have our outside ways of cooling off and heating up. (Clothes, swimming etc…) why you go from hot to cold when you have a cold. Your body is trying regulate its tempature. Your body also raises its internal temp to fight off diseases.
Because your body has always the same temperatura aprox. unless if you have a problem.
(First of all, I’m not a doctor so I could be perfectly misstaken).
The sweat is part of the cooling system that most animals have and we’re not different (In fact is one of our best advantages in terms of evolution compared to other animals, that is why the humans are the absolute chad in terms of hunting). When the enviroment is hotter than our body, by the laws of thermodynamics, we would be hotter until we reach the ambient temperature but our *cooling system* allow us to keep that temperature unless is something that the system cant hold ( This is when we have a heat stroke). When we’re on a colder enviroment the blood system restrict how much blood we have on our limbs and concentrate on the mayor organs and the brain to protect them and also we “burn” more nutrients to try to keep the temperature.
The chemical reactions always happen between a certan level of temperature so when we have more temperature that what is normal for us (Hiperthermia) or less than that (Hipothermia) those reactions needed to keep us alive begging to have problems, they could stop at all or just being more and more slow.
This is what happen for example when we have feber, our body tries to kill whatever infect us by raising the temperature but the body also suffers the blow.
(What I dont know is why if the body strategy is to warm up the body we sweat so much, maybe someone that knows more than me about it, which is not very difficult, could answer that. I’m really curious about it)
The “adapting to higher temperatures on hotter days” has a limit: wet bulb temperature >35C.
Our bodies use evaporative cooling to keep our internal temperature from climbing too high. Once evaporative cooling maxes out at 35C your internal temperature will climb to feverish and then deadly levels. The only remedy is to find or create a location that is cooler than 35C wbt.
Underground, dry the air, cool spring, HVAC, etc.
Something to keep in mind as extreme weather events become more frequent. A location at 35C 100% humidity will have a 100% mortality rate for anyone not able to find a cooler sheltering spot.
This simplest explanation of explicitly what you asked is actually philosophical, not scientific (in that, you really answered your own question):
We adapt to higher external temperatures through various means, like evaporative cooling from sweat.
If we have an increased internal temperature, it means we haven’t adapted in a manner to cool ourselves.
This has been brought to you by interpreting the semantics and ignoring the pragmatics.
