The stressful and fast-paced lives that many of us lead can deplete our resources in many ways.  Your adrenal glands produce the hormones and chemicals that keep you going in times of stress, giving you bursts of energy for the "fight-or-flight" response when necessary.  If you live at a higher level of stress at all times your adrenal glands will gradually fail to keep up with the demands, and eventually you wont even have the energy for simple daily activities.

This condition can be easily assessed with a urine collection to measure cortisol, one of your main adrenal hormones.  If your level is low there are natural medications and herbs that may be used to replace the lacking hormones and support your body's own production. 

The real answer lies in lifestyle change however.  Getting to bed on time (by 10p.m.), managing emotional stresses, eating healthy food, getting proper exercise and supplementing with necessary nutrients can get your body back on track for the long-term.  Using adrenal replacement and herbs as a "crutch" will only work for so long.  As usual, it is of utmost importance that you make proper lifestyle adjustments to achieve optimal health.
