The adrenal gland's job produce hormones that help the body control blood sugar, burn protein and fat, react to stressors like a major illness or injury, and regulate blood pressure.

If you are in constant "fight or flight" mode, your adrenals "Steal" hormones (instead of pregnenolone to estrogen, testosterone... it makes cortisol). Cortisol is meant to give you a boost TEMPORARILY to get out of a threatening situation. If cortisol remains in your body for an extended period of time it begins to eat at your tissue and your muscle. It's a CATABOLIC hormone! As a trainer, please educate your clients about critical muscle mass, this is real, it's not a myth. When you stress your adrenals to produce more cortisol then needed, you are loosing critical muscle mass.
A "fight of flight" state can be brought by just worrying about traffic, picking up the kids, how your sister-in-law is a bitch... from work environment to relationships, we could be flooding our body with unnecessary cortisol, which is made because your body decided it was in danger so instead of producing the "rest and digest" hormones, your producing cortisol. From digesting to trying to get pregnant, all that's put on hold. It DOES wear at the body, and it DOES LEAD to autoimmune disease such as Addison's. Addison's disease doesn't "Just happen," you MAKE it happen. You are forcing your body to use adrenals in a negative way. Just like you can lift weights the wrong way and wear out your joints, you can use your adrenals the wrong way which will affect every organ in your body.
