Adrenaline is produced in the medulla in the adrenal glands, as well as some of the neurons within the central nervous system. Within a couple minutes during a stressful situation, adrenaline is quickly released into the blood, sending impulses to organs to create a specific response. Also called epinephrine, adrenaline triggers the body’s fight-or-flight response when in a threatening situation.
The role of adrenaline in the body
An adrenaline rush occurs when a sudden increase in the secretion of adrenaline from the adrenal glands, as a result of the brain communicating to the glands there needs to be a fight-or-flight response. When we perceive something as exciting or threatening, the hypothalamus in the brain sends signals to the adrenal glands, and tells them to produce adrenaline along with other stress hormones. To produce adrenaline, the adrenal glands take the amino acid tyrosine and convert it into dopamine. Oxygenation of dopamine yields noradrenaline—which is converted into adrenaline—and then binds to arteries, the heart, liver, pancreas, muscles, and fatty tissue. In addition to physical threats causing a rush, strenuous exercise, heart failure, imagined threats, chronic stress, anxiety, or a disorder of the adrenal glands or brain.
In people suffering from heart disease, adrenaline rushes can be dangerous by causing weakening of the heart muscle, heart failure or a heart attack. When stress hormones are experienced on a continuous basis, the hippocampus—the brain’s main memory center, can shrink. According to the October 2008 Journal of Neuroscience, a research team found accelerated activity of adrenergic and noradrenergic neurons can have a profound, negative effect on memory.
On the other hand, mildly increased levels of stress hormones can have positive effects on the blood content of the protein leptin, which is produced in the body’s white fatty tissue. Stress hormones may possibly have the power to regulate the amount of leptin that fatty cells produce, and the less they do, the slower cancer cells will grow.
Everyone experiences an adrenaline rush at some point in their lives, and intermittent adrenaline rushes likely will not require any treatment. In some of the more intense cases, however, treatment may be necessary for chronic adrenaline rushes. Sometimes people experience anxiety or panic disorders, which trigger excessive secretion of adrenaline. In these cases, anti-anxiety medication or beta-blockers may be a good treatment choice.
