How may adrenal glands impact how you feel, think, and act?

Answer 1

They have considerable impact on your emotional well being.
They produce substances which work to assist in many bodily functions. They potentiate the transmission of neuro impulses, so that affects your thinking, your emotional state etc. They also produce substances that are antagonists for cortisol, the stress hormone, produced elsewhere in the body, so without those substances, people gain weight in their abdominal region, develop heart disease and so on. There are many benefits gained from what the adrenal glands produce.
