Why is the safe/normal temperature range of the human body so limited?


I’ve always been curious about this – I feel like I wouldn’t feel the difference between 37c/98f and 40c/104 if I was sitting in a bath. How come the difference is so significant inside your body?

Internal organs can definitely feel and notice the difference and the will function or not function accordingly

The human body is an enormously complex chemical reaction robot.

Temperatures affect how fast chemical reactions happen (and similar things like dissolving stuff in water).

If the reaction rates get too far out of whack, the chemistry gets out of whack, and starts to fail at the important job of keeping us alive. We might have too much of this, not enough of that, or a bunch of chemicals might start producing different products that weren’t intended.

As someone who owned a hot tub for a few years, you can definitely feel the difference between 98 & 104.

While there are other effects, the biggest thing keeping an organism only viable within a small temperature window are the enzymes it uses. Basically put, an enzyme is a protein that reduces the necessary energy required to make a reaction happen

If our enzymes even started finding it slightly harder to do the things they did, we would be dead. If it gets too hot, they may just stop working permanently due to unwanted reactions occurring, and if it gets too cold it won’t have the energy to make the wanted erections happen

TL;DR: important proteins do fucky wucky and throw a hissy fit if it isn’t in perfect conditions

Proteins are large, fragile molecules that make things in the human body work. For this reason, they are sometimes called living molecules. Many of them break apart at higher temperatures than, say, 105 -110 degrees Fahrenheit. When this happens, you die.
