“A lot of people like snow. I find it to be an unnecessary freezing of water.” – Carl Reiner
At its core, the human body is a symphony of chemical reactions. The complexities and interdependencies of the molecular machinery that makes our bodies function are almost too staggering to ponder. As any chemist can attest, chemical reactions are usually quite sensitive to temperature, and sensitivity to temperature varies substantially across reaction pathways. As such, temperature control not only dictates reaction rates, but it also influences product and byproduct distributions. At one temperature, two reagents might react cleanly to produce a desired product with high purity. At a different temperature, an undesirable pathway might become more kinetically favored, leading to the accumulation of unwanted impurities.
One of the miracles of the body is its ability to maintain strict internal temperature control, which allows it to regulate the speed and product distributions of the myriad of chemical reactions that are occurring inside you as you read this. The equilibria are delicate, so much so that fluctuations of a mere few degrees can be fatal. This concept of “normal” body temperature is widely understood, but its direct, vital connection to the core chemical reactions occurring inside you is less well known.
