Explanation:

How does cortisol affect stress?

As your body perceives stress, your adrenal glands make and release the hormone cortisol into your bloodstream. Often called the “stress hormone,” cortisol causes an increase in your heart rate and blood pressure. It's your natural “flight or fight” response that has kept humans alive for thousands of years.

What is cortisol?

Cortisol, the primary stress hormone, increases sugars (glucose) in the bloodstream, enhances your brain's use of glucose, and increases the availability of substances that repair tissues. Cortisol also curbs functions that would be nonessential or detrimental in a fight-or-flight situation.
