Are you feeling stressed? A bit fatigued? Let?s look at the hormones related to stress. Epinephrine, also adrenaline, is a hormone secreted by the adrenal gland. Epinephrine normally is present in the bloodstream in minute quantities. In times of excitement or emotional stress, however, epinephrine is secreted, exerting a marked effect on body structures in preparation for physical exertion. For example, epinephrine stimulates the heart, constricts the small blood vessels, raises the blood pressure, releasing sugar stored in the liver, and relaxes certain involuntary muscles while contracting others.

The adrenal gland also secretes norepinephrine, a substance chemically related to epinephrine. It is a chemical agent responsible for transmission of nerve impulses in the autonomic nervous system. Large amounts of epinephrine and norepinephrine are produced by some tumors of the adrenal glands, resulting in a great increase in blood pressure.

The adrenal glands, skin, and brain also produce a sex steroid hormone called dehydroepiandrosterone (DHEA). DHEA is associated with levels of vigor and vitality and the rate of aging. DHEA is commonly known as the "Fountain of Youth" hormone.

The adrenal cortex produces the glucocorticoid hormone cortisol, more commonly known as the stress hormone. Cortisol a derivative or cortisone, helps the body cope with stresses of all kinds.

In conclusion, monitoring these hormone levels is essential for maintaining a healthy response to physical and emotional stress. An imbalance of cortisol, DHEA, Epinephrine and Norepinephrine can influence the immune system, sleep patterns, and energy levels.
