If you are asking how you can tell whether you are suffering from adrenal stress/burnout, check this out:
"How Can You Tell If Your Adrenal Glands Are Stressed Out?"
Traditional medicine recognizes only the most extreme form of adrenal burnout: Addison's disease, a potentially life-threatening condition in which the adrenals make no cortisol hormones. However, there's a wide spectrum of diminishing function between healthy adrenals and Addison's disease. A person could feel horrible and have virtually no energy because of poor adrenal function and yet not show any abnormalities on the standard adrenal function test.
If your adrenal glands are stressed out, you
may experience:
Chronic fatigue.
Lightheadedness.
Cold hands and feet.
Low blood pressure.
Loss of appetite.
Food or environmental allergies.
Cravings for salt or sweets.
Headaches.
Nervousness and irritability.
Dry skin.
Thinning hair.
Excessive worrying and weeping.
Dr. Robert Atkins suggests a simple method for determining if your adrenal glands are working properly. (You'll need a blood pressure gauge to do this test.):
Have your blood pressure gauge nearby.
Lie down and rest for 5 minutes.
Take a blood pressure reading while still lying down.
Stand up.
Take your blood pressure again, immediately.
If your blood pressure is lower when you stand up, your adrenal glands are probably stressed. The greater the drop in pressure, the more stress your adrenals are experiencing. Note: If your blood pressure drops significantly when you stand up, you should probably discuss the problem with your physician.
In addition, if you hit the wall about 3pm each day, I'd say that's a pretty big indicator of adrenal stress.
