Crazy cortisol....a stress hormone produced in the adrenal gland...how does it affect my body?
Here are some...
-increased appetite and larger stores of abdominal fat (with a high exposure of cortisol over time)
-suppresses the immune system
-anti-diurectic
-increased blood sugar
-increased blood pressure

What can increase cortisol levels?  Anorexia nervosa, long-term exhaustion, sleep deprivation, alcohol, and caffeine.

Manage your stress.  Schedule time to de-stress...even if it is 5 minutes of your day.  This will help decrease those cortisol levels.  Try some music therapy or yoga or something that de-stresses you.
