How is cortisol good for you?
When cortisol is secreted, it creates the following:
- A breakdown of muscle protein, leading to the release of amino acids (which
are the "building blocks" of protein) into the bloodstream.
- These amino acids are then used by the liver to synthesize glucose for energy,
in a process called gluconeogenesis.
- This process raises the blood sugar level so the brain will have more glucose
for energy.
- At the same time, the other tissues of the body decrease their use of glucose
as fuel.
- Cortisol also leads to the release of so-called fatty acids, an energy source
from fat cells, for use by the muscles.
- Taken together, these energy-directing processes prepare the individual to deal with stresses and ensure that the brain receives adequate energy sources.
