The Stress Hormone: Cortisol
by Jess Mullen, MS, RD, RRCA Certified Running Coach
Cortisol, a glucocorticoid (steroid hormone), is produced from cholesterol in the two adrenal glands located on top of each kidney. It is normally released in response to events and circumstances such as waking up in the morning, exercising, and acute stress.
Through a combination of nerve and hormonal signals, this system prompts your adrenal glands, located atop your kidneys, to release a surge of hormones, including adrenaline and cortisol.
Adrenaline increases your heart rate, elevates your blood pressure and boosts energy supplies. 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. It alters immune system responses and suppresses the digestive system, the reproductive system and growth processes. This complex natural alarm system also communicates with the brain regions that control mood, motivation and fear.
The body's stress-response system is usually self-limiting. Once a perceived threat has passed, hormone levels return to normal. As adrenaline and cortisol levels drop, your heart rate and blood pressure return to baseline levels, and other systems resume their regular activities.
But when stressors are always present and you constantly feel under attack, that fight-or-flight reaction stays turned on. The long-term activation of the stress-response system and the overexposure to cortisol and other stress hormones that follows can disrupt almost all your body's processes. This puts you at increased risk of many health problems, including: Anxiety, Depression, Digestive problems, Headaches, Heart disease, Sleep problems, Weight gain, Memory and concentration impairment...
