Enzyme strength depends on temperature

How temperature affects the enzymes

Enzymes become soft and lose their firmness and rigidity if temperatures are too warm. If temperatures are too cold, enzymes become too rigid and lack the necessary flexibility and adaptability. Both states quickly affect the optimal functioning of our digestive system resulting in an impaired metabolism and organism as a whole. Processes occur with great ease, minimal loss and optimal speed at an optimal temperature (98.05°-99.15°F); however, outside of this temperature range the same processes require more energy, accelerate depletion and are prone to more errors. The entire metabolism suffers if our body temperature is too hot, too cold or too unstable since the enzymes are not in their optimal structure.

High fevers have, therefore, always been a great concern to medical professionals since high temperatures can denaturize the enzymes in the brain. The loss of form can trigger a life-threatening delirium. The dangers of extreme low temperatures are, of course, also well known in emergency medical care, e.g. when treating people buried in avalanches or pulled from frigid waters. This makes it all the more surprising that a fever is taken seriously by the medical profession while milder lower temperature deviations are barely acknowledged. Temperatures that deviate from the norm or optimum are always a step towards poor health and illness. If a high fever or an extremely low temperature is regarded as life-threatening, mild deviations from the norm should at least be regarded as indications of poor health that can cause illness, especially when these conditions become chronic. Every loss of vitality and optimal enzyme activity always means a loss of functionality for the respective organ, tissue or body part. This can be a decisive disadvantage in survival situations.


This chart shows 100% enzyme activity at 98.6° Fahrenheit while lower and higher temperatures already indicate a massive loss of enzymatic capacity.

Why is it precisely this temperature window around 98.5°F that is most beneficial for us humans? The enzymes that provide an essential function for the well-being of our organism have most likely been calibrated to this temperature range by evolution. Some enzymes also function in deviating conditions. It becomes apparent that the enzymes that are most quickly affected by temperature deviations are responsible for non-essential functions. Our bodies can absorb functional losses if these enzymes are not operating properly; however, such losses nonetheless indicate a deviation from the norm.
